Purchasing Chillers and Mini Chillers
Category: Chillers
A chiller is an air conditioning system that produces the cold water required for air conditioning systems. This chilled water enters various systems, such as air handling units and fan coil units through pipelines and pumps. In large buildings, absorption and compression chillers can be used to produce thermal energy from domestic hot water. For larger buildings with greater areas, it is more sensible and cost-effective to purchase a chiller system.
 
Purchasing Chillers
What Is a Domestic Chiller?
Heating or cooling has become essential in today’s environments. If you are buying or renting a home or visiting an office space, evaluating its heating and cooling system should be a top priority. A domestic chiller is one of the most common and efficient systems in this regard.
A domestic chiller is designed to regulate the temperature in smaller spaces, like apartments. These chillers, which possess an air condenser, are typically placed in outdoor areas such as courtyards or rooftops.
 The main purpose of a domestic chiller is to independently warm up or cool down the apartments or buildings that do not have central heating and cooling systems.
 Due to their structures, these chillers distribute comfortable air throughout the apartment or building. In the summer, the system cools the building using fans and coils to make the air inside comfortable. In winter, the system transfers hot water from hot water packages into the coils, thus warming the space.
 A mini domestic chiller is a small-scale cooling system that pumps cold and warm air through fans and coils to produce cool or hot air.  It should be noted that domestic chillers are often used in spaces larger than 150 m2.
 Domestic or mini chillers are connected to several fan coils through a water piping system. The cooled water is transferred to the coils with the help of a pump. Each fan coil has a copper coil and fan, which blows air through the cooled coils, thereby regulating the environment’s temperature.
 
 What Is an Industrial Chiller?
Industrial chillers are among the most important cooling equipment in many industries. They utilize a cycle of compression, evaporation, condensation, and expansion of refrigerant to produce cool air.
 
The industrial chillers have numerous benefits:

Ensuring Ideal Temperatures for Industrial Processes: Chillers can provide the required temperatures for various industrial applications.
Increasing Energy Efficiency: Modern industrial chillers have high energy efficiency, and thus significantly reduce energy expenses.
Reliability: Chillers have durability and stable design and can work with great reliability over time.

Components of a Domestic Chiller
Air Handling Unit (AHU): The air handling unit plays an important role in air conditioning systems. It not only provides clean, purified air but also has the ability to heat and cool the air but it is important to note that the air handling unit only distributes hot or cold air. Therefore, another device that can generate cold air is required to cool the air. In this case, a chiller is the best solution. Thus, a chiller is necessary for distributing the generated air. This makes AHU a vital component. Given its importance, the cost of AHU is reasonable.
 
 Compressor: Compressors have different types, but screw or scroll compressors are commonly used in domestic mini chillers. Their main function is to compress the refrigerant.
 Condenser: The condenser cools the refrigerant, using either water or air depending on the type. For mini chillers, the refrigerant cooling process is usually achieved by air.
Evaporator: This part of the chiller facilitates the heat exchange between the refrigerant and water.
 Expansion Valve: After the refrigerant exits the condenser, it enters the expansion valve and then enters the evaporator. At this stage, the refrigerant undergoes a significant pressure drop.
 

Benefits of Domestic Mini Chillers
The mini chiller is a small cooling device designed for various purposes, including water cooling, air cooling in small spaces, or cooling electronic equipment. The key benefits of this device are as follows:
Small Size: The mini chiller is small in size, making it suitable for installation and use in compact spaces or specialized environments.
Low Energy Consumption: Many models of mini chillers are built with modern technologies that save energy and enhance performance.
Easy Transportation: Transporting the mini chiller is easy due to its lightweight and small size.
Multi-Purpose Use: This device can be employed for cooling water in dental clinics, cooling air in small rooms, or cooling electronic devices.
Minimal Noise and Vibration: Advanced design features in many mini chiller models produce little noise and minimal vibration.
Easy Maintenance: Many mini chillers are equipped with easy maintenance and cleaning systems, enabling optimal use.
 
The use of mini chillers in various cases enhances users’ quality of life and provides greater comfort due to the aforementioned benefits.
 
 What Area is Ideal for Using These Domestic Chillers?
Domestic chillers are greatly similar to air-cooled chillers but with significantly smaller sizes and lower capacities. They also have an internal pump and expansion tank. Domestic chillers are usually suited for areas with an area of 150 m2 or more. It is worth mentioning that for spaces between 150 to 300 m2, a mini chiller is ideal, while spaces larger than 300 m2 would be better to have a central chiller.
 
 The advantage of domestic chillers over split systems is that several fan coils can be connected to a single domestic chiller, allowing independent temperature control for each fan coil. In contrast, a ducted split system is a central air handling unit in a false ceiling, distributing cool or warm air to rooms via ducting. The problem is that the air conditioning system for all rooms or halls connected to a ducted system shares the same air temperature, with the system turning on and off together.

How a Chiller Operates
A chiller is a device that removes heat from a liquid using the refrigeration cycle. The cooled liquid can then be used in systems such as fan coils and air handling units. In addition to its use in air conditioning and cold-water production, chillers are also used in industrial processes in which this fluid is used to reduce the temperature of machinery.
 

Applications of Domestic Chillers
Domestic chillers can be used in various settings. Here are some common uses:

Domestic chillers can be used in yards, rooftops, or terraces.
They are suitable for areas that exceed 150 m2 in size.
Fan coils can be installed in individual rooms and connected to a central chiller system. 

 
Types of Domestic Chillers
Chillers are different in terms of functionalities and consumption type but they can generally be classified into two main types:

Compression Chillers
Absorption Chillers

 
Below, we deeply study both types of chillers.
 

Types of Chillers
What is a Compression Chiller?
In a compression chiller, the compressor increases the pressure of the gas, which then enters the condenser, transforming it into a liquid. This liquid is directed through an expansion valve into the evaporator, where the water’s heat is absorbed. (For price information, you can contact the HiWater team.)
Compression chillers are commonly used for cooling both building spaces and industrial environments. They produce cold water that is sent to air distribution systems, such as fan coils, and then cool the space. With their evaporator, compression chillers can create water temperatures lower than freezing.
There are two main types of compression chillers: water-cooled and air-cooled. Water-cooled chillers are often used in boiler rooms, while air-cooled chillers are usually installed on rooftops or in yards.
In water-cooled systems, the refrigerant passes through the evaporator pipes, and air flows over the pipes but in air-cooled systems, fans are used to cool the refrigerant. Therefore, a benefit of air-cooled chillers is that they do not require water.
  
Types of Compression Chillers
Compression chillers are divided based on the type of condenser: air-cooled or water-cooled. Additionally, they can be categorized by their compressor type into four options:

Screw Compressor
Scroll Compressor
Piston Compressor
Centrifugal Compressor

 
 Types of Compressors in Compression Chillers
A screw compressor uses a spiral mechanism to compress the refrigerant gas, which is then sent to the evaporator, expansion valve, and condenser for cooling the water. Screw compressors are known for their complex oil-lubrication systems, high efficiency, and positive displacement. Compared to other compressors, screw compressors have several advantages:

Low vibration
Low noise
Long operational life
High reliability
Low discharge temperatures

Other benefits include their smaller size, a reciprocating type, and lower maintenance costs, making them more cost-effective and easier to be repaired.

Key Components of a Compression Chiller
Compressor: The role of a compressor is to compress the refrigerant gas, which increases its pressure and temperature.
 

Evaporator: The evaporator is a heat exchanger that is used in the shell-and-tube chillers. Refrigerant gas flows through tubes and water passes around them. The refrigerant gas absorbs the water’s heat, cooling the water and sending it to air conditioning systems by a pump.
 

Switchboards
Vibration Dampers
Expansion Valve: The expansion valve reduces the refrigerant’s pressure after it leaves the compressor. It diminishes the pressure on the refrigerant, making it into gas before sending it to the evaporator.
  
How Compression Chillers Work
In compression chillers, the refrigerant gas first enters the compressor, where it is compressed and then sent to the condenser to cool down. The refrigerant gas is then condensed into a liquid through cooled air.
The remaining liquid is sent to the expansion valve. From there, it moves to the evaporator, where pressure reduction causes it to evaporate into gas. This evaporation process cools the surrounding components. The generated vapor is then returned to the compressor.

What is a Domestic Absorption Chiller?
An absorption chiller is a type of air conditioning system used for cooling. This system operates using an absorption cycle, where thermal energy is converted into cooling energy. Instead of a compressor, an absorption chiller uses a thermal generator and an absorber. Lithium bromide is the cooling agent in absorption chillers.
 
 Purchasing Absorption Chillers
Purchasing HiWater Absorption Chillers
Main Components of an Absorption Chiller
Condenser The condenser is at the top of absorption chillers and serves to condense the refrigerant vapor, which is evaporated by the generator. Indeed, refrigerant vapor condenses when contacting the cold pipes.
 
Evaporator
The evaporator is at the lower part of the absorption chiller. In this component, the refrigerant liquid evaporates due to the low pressure in the evaporator chamber, thereby decreasing the temperature of the water in the evaporator tubes.
 
Generator It is located at the upper part of the absorption chiller, and it separates the water vapor from the lithium solution.
 
Absorber It is in the lower shell of the absorption chiller and is responsible for absorbing the vapor from the evaporator.
 
 How Absorption Chillers Work
The operation starts with the water vapor being cooled by a substance called lithium bromide, then absorbed by the evaporator. The pump moves the lithium bromide solution to the thermal generator. The solution then evaporates, enters the condenser, and the cycle continues.
 
Advantages of Absorption Chillers
 
Lower Noise and Vibration
Absorption chillers generate much less noise and vibration compared to compression chillers. This is due to the absence of a compressor in absorption chillers, but instead, it is equipped with small pumps that circulate the lithium bromide solution.
Reduced Electricity Consumption
These chillers consume far less electricity since they do not rely on electric power as a primary energy source.
Return on Initial Investment
Absorption chillers consume less electricity, which significantly reduces operating expenses. Even though the initial cost of purchasing a compression chiller is much lower than an absorption chiller of the same capacity, the considerable energy savings by an absorption chiller demonstrate that it is more economical in the long term.
Decreased Greenhouse Gas Emissions and Pollutants
Absorption chillers produce fewer greenhouse gases and pollutants than compression chillers, thereby reducing environmental pollution.
 
 Domestic Chiller Price
Price of Purchasing a Domestic Chiller
Initial Boiler Cost Savings in Chillers
Absorption chillers can be used as heaters, which helps decrease heating costs.
  
Refrigerant Type in Absorption Chillers
Absorption chillers use distilled water as refrigerant, which is safe but compression chillers use chlorofluorocarbons (CFCs), which can harm the environment.
Absorption chillers are generally taller than compression chillers and the height of the boiler room should also be designed to be high.
They also use significantly less energy compared to air conditioning units or similar systems. A separate fan coil unit can be connected to each room, which is then attached to the chiller.
These chillers can be installed in yards, terraces, or rooftops.
Absorption cycles differ from compression cycles in two main ways:
In absorption cycles, the compressor is replaced by a pump, a generator, and an absorber. In fact, a primary and a secondary refrigerant, which is called the absorber, are used.
 

Types of Absorption Chillers
Absorption chillers have cooling capacities ranging from 100 to 1000 tons of refrigeration. Domestic absorption chillers have several types, including:
 
Type of Heat Generator in Chillers
These chillers use hot water, steam, or direct flame.
 
Type of Absorption Chiller Mechanism
These chillers can be either single-effect or double-effect.
 
Types of Refrigerants and Absorbent
 
Water and Ammonia Absorption Chillers: In these chillers, ammonia is the refrigerant, and water is the absorbent.
 
Water and Lithium Bromide Absorption Chillers: This type uses water as the refrigerant and lithium bromide as the absorbent, making it more common in industry.
 

Differences Between Absorption and Compression Chillers
Absorption chillers are generally suitable for capacities over 1000 tons of refrigeration but while compression chillers are economical for capacities above 600 tons. Furthermore, compression chillers have more applications. A comparison of the two is presented as follows:
 

Compression chillers consume a much higher amount of electricity than absorption chillers.
Absorption chillers occupy more space.
Absorption chillers require significantly more water.
Compression chillers are easier to maintain compared to absorption chillers which operate under vacuum conditions.
Absorption chillers are less effective in humid climates.
Absorption chillers can be connected to Combined Heat and Power (CHP) systems.
Absorption chillers can be connected to systems of the boiler room.
Absorption chillers use fossil fuels.
Absorption chillers generally have a shorter lifespan because of the corrosive effects of the absorbent materials.

Difference Between Domestic and Building Chillers
Domestic and building chillers differ in several ways as follows.

The most significant difference is in their capacity: Domestic chillers have capacities of up to 12 tons, while building chillers can reach up to 850 tons, with some models as high as 2500 tons of refrigeration.
Another difference is their compressor types: Domestic chillers use hermetic scroll compressors but building chillers can use piston, scroll, screw, and centrifugal compressors.
The condensers of domestic and building chillers also vary: domestic units use air-cooled condensers to cool down heat but building chillers can use either water-cooled or air-cooled condensers according to the capacity of domestic chillers.
Domestic chillers are designed for outdoors but building chillers are installed in boiler rooms (due to differences in their condensers).
Finally, domestic chillers include a pump and an expansion vessel within the system but building chillers lack pumps and expansion vessels as they depend on pumping mechanisms and require pipelines with indefinite lengths.

 
 Mini Absorption Chiller Performance in Cooling and Heating
Mini absorption chillers are highly effective for both cooling and heating. Here’s how they work at each temperature:
  
Domestic Mini Chillers in a Cooling Mode
The main reason for using chillers and mini chillers is for cooling. Therefore, in cooling mode, the refrigerant enters the compressor, where it is compressed, increasing pressure and temperature for circulation in the refrigerant cycle. The refrigerant is then heated and transferred to the condenser, where it cools down by releasing heat to the surrounding air, transforming it into a mix of liquid and vapor. The refrigerant then moves to the expansion valve, experiencing a sudden pressure drop, and enters the evaporator. Here, it absorbs heat from the water being cooled, and the process completes when the refrigerant returns to the compressor. Meanwhile, the water loses heat and is sent to the cooling devices, such as air handling units and fan coils.
 

How Domestic Heating Mini Chillers Operate
When water heating starts, it is first heated by steam generators of the boiler room or boilers. However, when it comes to mini chillers, it is more efficient and reasonable to use the hot water produced by the packages. To this end, the heating system’s piping or boiler is connected to the domestic chiller and the hot water is then transferred to the consumption devices, ensuring the heating of the environment.
 
How Domestic Cooling Chillers Operate
In these types of chillers, the liquid enters the evaporator and undergoes cooling. This cooled liquid is then sent to fan coils or air handlers by pumps, and cool down the environment.
 
How Domestic Heating Chillers Operate
A domestic heating chiller requires a connection to a flow of hot water. To generate this hot water, a heating system, like a boiler or a package, must be used. Domestic chillers usually rely on wall-mounted packages. The hot water produced then flows through the fan coil’s coil, and the warm air is sent to the environment.

The Difference between Chillers and Split Systems:
Chillers are devices that produce only cool water, delivered to air conditioning units such as fan coils and air handling units, where it cools the air in the room but split systems and air conditioners use refrigerant to cool the space directly.
 
Choosing the Best Chiller for Residential Apartments and Houses
If you are looking for a heating and cooling system for your house, you can select the most modern and specialized cooling system. When selecting the right chiller for your house, consider the size of the property, and then choose a suitable fan coil based on that.
 
Key Considerations When Selecting a Chiller for Different Projects

Climate: Weather and environmental conditions have a significant effect on the choice of chiller.
Temperature: These are categorized into mild, cold, and tropical (hot) climates.
Humidity: Humidity levels are divided into dry, moderate, and humid categories.

Best Chiller for Factories
Factories are usually larger than 1,000 m2, and selecting the right chiller depends on the local climate conditions. Generally, compression chillers are used in factories, along with fan coils or air handlers.
 
About Air Conditioning Chillers
Heating and cooling systems, including chillers, fan coils, and air handling units, provide heating and cooling options for all seasons. In air conditioning systems, chilled water produced by chillers is used to lower the temperature in various types of spaces such as industrial, office, and commercial environments.

What is an Industrial Chiller?
An industrial chiller is used in different industries to absorb excessive heat. This chiller cools through either compression or absorption refrigeration processes. The cooling produced is used for equipment cooling, dehumidification of compressed air, and air conditioning purposes.
 
Structure of an Industrial Chiller
These systems are generally used in compression-type industries. Depending on the requirements, industrial chillers can either be air-cooled or water-cooled. The structure of an industrial chiller closely resembles a compression chiller, consisting of four main components, namely evaporator, condenser, compressor, and expansion valve, in addition to several other parts.
 
Prices of Industrial Chillers
The price of an industrial chiller varies based on its temperature range, as chillers come in various ranges to suit different needs. Each project requires a specific chiller. To determine the cost of an industrial chiller, factors such as cooling capacity (nominal and actual), operational temperature range, installation location, duration of use, compressor type, component brand, build quality, and type of expansion valve must be taken into account.
When considering these factors, it becomes clear that domestic chillers offer a wide variety of options, leading to a range of prices. However, each of these factors individually affects the price of an industrial chiller.
 
For example, the cooling capacity of a chiller plays a key role in its pricing. Chillers are available in various capacities, and typically, the higher the capacity, the more expensive the unit. For example, a 200-ton chiller will be much more expensive than a 30-ton one.
 
Regarding the operating temperature range, chillers are generally produced in two categories: below zero and above zero because some projects require temperatures below freezing, and this requirement, along with other factors, affects the price.
 
Regarding the site where the chiller will be installed, it can be used in different environments, but this is related to the wide variety of available devices. For example, in environments with high humidity or in cities with hard water, a chiller suitable for those conditions should be selected. This is another factor contributing to the range of prices for these systems.
 
 In areas with hard water, additional equipment, like water softeners, are necessary alongside the chiller. If the water is soft, such extra equipment is not necessary
 Regarding the type of compressors, by exploring additional articles on the website about chillers, it becomes clear that compressors come in various models in terms of functionality, capacity, and other characteristics. Each chiller uses a specific compressor based on certain factors. Some examples of compressor types include screw, scroll, centrifugal, and others. These models differ in price due to their distinct performance characteristics and design features, which ultimately affect the overall price of the chiller.

Industrial Chiller Maintenance: Considering that industrial chillers operate for extended hours, proper maintenance is important. Taking good care of these systems can significantly reduce electricity consumption and maintenance costs, while also increasing their operational efficiency. Routine checks on industrial chillers should be conducted daily, weekly, and monthly to detect any issues early, prevent costly repairs, and enhance the equipment’s lifespan.
 
 Important Tips for Maintaining Industrial Chillers:
Begin by taking notes from the performance of the chiller in various components.
In compression chiller models, water passes through the condenser and circulates within the system. As part of this process, some water vaporizes, making it crucial to control water hardness. Excessive hardness can raise the biological level of the water, which may cause corrosion and damage to the condenser pipes.
 Compression chillers should undergo an acid wash annually to avoid performance issues, such as reduced efficiency and increased energy consumption.
During the maintenance of industrial chillers, particularly compression chillers, ensure that the water flow rate remains within standard limits, as fluctuations in water flow can significantly affect chiller performance.
Regularly check the compressor oil, as it influences the overall functioning of the chiller, including cooling water, dissipating heat, and circulating air.
 
For optimal performance while maintaining a chiller, consider installing a driver and using variable-frequency inverters in the chiller.
To sum up, during industrial chiller maintenance, servicing, and repairs, the following points should be observed:

Monitor the inlet and outlet temperatures.
Control the chiller amperage consumption.
Inspect the water filters.
Pay attention to vibrations in the compressor and fan.
Clean the cooling tower.
Wash the condenser.
Control oil levels of suction and discharge pressures.
Pay attention to noise of the fan or compressor.

About Air-Cooled Chillers:
An air-cooled chiller is a type of compression chiller. The term “air-cooled” comes from the design of its condenser because it cools the refrigerant by drawing in ambient air. Therefore, this type of chiller should be positioned in an open area to allow the condenser to effectively exchange heat with the surrounding environment.
Air-cooled chillers are designed to function in various climatic conditions, especially in humid areas.
 
Price Differences Between Air-Cooled and Water-Cooled Chillers:
To make a comparison of these two types of chillers in terms of their prices, we must examine them at equal capacities. In general, air-cooled chillers are more expensive than water-cooled ones. Several reasons contribute to this price difference, which we will explain in further detail.
  
One significant reason for the higher cost of air-cooled chillers is the size of the switchboard. As you may know, the switchboard plays a vital role in the operation and lifespan of the chiller. Switchboards vary in size and features, and their main function is to protect components such as pumps and compressors. Additionally, the switchboard manages the chiller’s performance, including energy consumption and switching, and because the air-cooled chiller’s switchboard is larger, the overall cost of the chiller also increases.
 
Since air-cooled chillers utilize fans to improve heat transfer between the air and the condenser, which requires additional protective components for fan control. This adds to the overall cost. Moreover, the compressor in an air-cooled chiller is larger than that in a water-cooled chiller, contributing to the higher price of the air-cooled version.
