What is an Air Cooled Chiller?
ChillerOne air cooled chiller uses ambient air as the cooling medium and dissipates the heat generated by the system into the atmosphere through its own equipped fans and condensers. Therefore, it does not rely on an additional cooling water system.
Our air cooled chiller has a simple structure and is easy to install. It operates for cooling only with ambient air, achieving remarkable energy-saving effects. Its energy efficiency is usually lower than that of water-cooled units that require cooling towers.
Working Principle of Air Cooled Chiller
- Step 1: After the refrigerant absorbs the heat of cold water in the evaporator, it turns into low-temperature and low-pressure steam. Then it enters the compressor and is compressed into high-temperature and high-pressure steam.
- Step 2: When the high-temperature and high-pressure refrigerant vapor enters the condenser, the fan forces the ambient air to flow through the condenser coil, taking away the heat of the refrigerant, causing it to cool and condense into a high-pressure, normal-temperature liquid.
- Step 3: Subsequently, the high-pressure liquid refrigerant flows through the expansion valve, and its pressure and temperature drop sharply.
- Step 4: The low-temperature and low-pressure refrigerant wet vapor enters the evaporator, absorbs the heat of the cold water flowing through the evaporator, and evaporates into gas, thereby cooling the cold water. The cooled cold water is then transported by water pumps to various places that need refrigeration, forming a repetitive cycle process.
Components of Air Cooled Chiller
Compressor
The compressor provides power for the refrigeration cycle flow by compressing the low temperature and low pressure refrigerant vapor into a high temperature and high pressure state.
- Screw Compressor: The screw compressor is a type of positive displacement compressor. When the motor drives the rotor to rotate, the refrigerant gas is captured, compressed and pushed towards the exhaust end between the rotor teeth and grooves, thus completing a continuous and smooth compression process.
It features a compact structure, smooth operation, long service life and good regulating performance, making it an ideal choice for medium to large cooling capacity air cooled chillers.
- Scroll Compressor: The scroll compressor is composed of a stationary scroll and a moving scroll nested within each other. The moving scroll rotates translationally around the center of the stationary scroll driven by the motor, forming a sealed cavity between the two. As the moving vortex disk moves, the volume of the cavity continuously shrinks, continuously compressing the inhaled low-pressure refrigerant gas and pushing it towards the exhaust port.
It features a simple structure, extremely low noise and vibration, and high reliability. It is the most commonly used compressor type in small and medium-sized air cooled chillers.
Condenser
Condensers are usually composed of copper tubes and aluminum fins. When the high-temperature and high-pressure refrigerant flows through its internal pipes, the condenser fan will drive the ambient air to the outside of the finned tubes, taking away the heat of the refrigerant and causing it to cool and condense, transforming from high-pressure gas into high-pressure liquid.
Condenser Fan
The condenser fan provides the forced convection cooling airflow required by the condenser. It conveys ambient air to the condenser through powerful ventilation, and then this air will carry away the heat carried by the refrigerant into the atmosphere.
Evaporator
Evaporators are usually of shell and tube structure. The low-temperature and low-pressure liquid refrigerant from the expansion valve flows in the pipes of the evaporator, while the water that needs to be cooled flows outside the pipes. The refrigerant absorbs the heat of water and evaporates into a gaseous state, thereby forcibly lowering the temperature of the flowing liquid and continuously providing chilled water to external devices.
Expansion Valve
The expansion valve is typically located between the condenser and the evaporator. It can reduce the pressure of the high-pressure, normal-temperature liquid refrigerant from the condenser into a low-temperature, low-pressure, mist-like mixture that is easy to evaporate. In addition, it automatically adjusts the flow of refrigerant entering the evaporator based on the superheat at the end of the evaporator, ensuring that the refrigerant is fully and efficiently utilized within the evaporator. This not only avoids a decrease in refrigeration efficiency due to insufficient flow but also prevents liquid hammer damage to the compressor caused by excessive flow.
Drying Filter
The drying filter is usually installed on the liquid pipe between the outlet of the condenser and the inlet of the expansion valve. Its interior is filled with desiccant and filters to adsorb and remove trace amounts of moisture and solid impurities that may be present in the refrigerant, preventing impurities from clogging the expansion valve, which ensures the safe and reliable operation of the entire air cooled chiller.
Advantages and Disadvantages of Air Cooled Chillers
Advantages
- Simple System: ChillerOne air cooled chillers do not rely on complex cooling water systems such as cooling towers and cooling water pumps. Their system composition is simple and installation is convenient, and the cost is usually lower than that of water cooled chillers.
- Space-Saving: You can directly install it on the roof, ground or outdoors, which makes it particularly suitable for water-scarce areas or places where cooling towers cannot be installed.
- Easy Maintenance: The daily maintenance of our air cooled chiller mainly focuses on cleaning the condenser fins and inspecting the fan. You don’t need to deal with common problems in the cooling water system such as scale, algae and bacterial growth, and the maintenance workload is relatively small.
Disadvantages
- Lower Energy Efficiency: Due to the fact that the heat exchange efficiency of air is much lower than that of water, the condensing temperature of air cooled chillers is higher, and the compressor needs to consume more power. Therefore, its energy efficiency ratio is much lower than that of water cooled chillers.
- Affected by Environment: In the hot summer weather, its condensation effect will significantly decline, resulting in a decrease in cooling capacity and energy efficiency.
- High Noise: Both the compressor and the fan are located in the outdoor unit, generating considerable noise during operation, which may have an impact on the surrounding environment. You need to consider the rationality of the installation location.
Comparisons Between Air Cooled Chillers and Water Cooled Chillers
Cooling Method
