Working Principle:
The main components of an air-cooled chiller include a compressor, an air condenser, an expansion valve, and an evaporator. Here is a basic overview of its workflow:
1.The compressor takes in low-pressure, low-temperature refrigerant gas and compresses it into high-pressure, high-temperature gas.
2.This high-temperature, high-pressure refrigerant gas enters the air condenser, exchanges heat with the ambient air, and discharges heat to the environment, while the refrigerant condenses from a gaseous state to a liquid state.
3.The high-pressure refrigerant liquid passes through the expansion valve, the pressure suddenly drops, and it turns into a low-pressure and low-temperature refrigerant liquid.
4.The low-temperature and low-pressure refrigerant liquid enters the evaporator, absorbs indoor heat, evaporates into a gaseous state by itself, and the indoor temperature drops to achieve the purpose of refrigeration.
5.The refrigerant gas is sucked into the compressor again to complete a cycle.
The advantages of air-cooled chillers include simple installation, no need for cooling towers and cooling water pumps, and low maintenance costs. However, its efficiency is lower than that of water-cooled chillers, especially at high ambient temperatures, and its efficiency will be further reduced

How does the energy efficiency of air-cooled cryogenic chillers compare to water-cooled methods?
There are some differences in energy efficiency between air-cooled low-temperature chillers and water-cooled methods.
1. Heat dissipation efficiency: The water cooling method transfers heat to the cooling water through the water cooler, and then discharges the heat through the cooling water circulation system. In contrast, air-cooled low-temperature chillers dissipate heat directly to the surrounding environment through built-in fans and radiators. Due to the higher specific heat capacity of water, water cooling usually has higher heat dissipation efficiency and can remove heat more effectively.
2. Energy consumption: Since the water-cooling method requires additional water-cooling equipment and a water circulation system, in comparison, air-cooled low-temperature chillers usually have lower energy consumption. The air-cooled low-temperature chiller does not require additional water pumps and cooling water circulation systems, thus saving water energy consumption and pump energy consumption.
3. Environmental adaptability: The water cooling method requires a stable water supply and drainage system, and is suitable for areas with sufficient water resources. The air-cooled low-temperature chiller does not require water sources and drainage systems, and is suitable for various environmental conditions, especially in areas where water resources are scarce or where water-cooling equipment cannot be used.
It should be noted that the specific energy efficiency comparison is also affected by other factors, such as the design of the equipment, the efficiency of the compressor, and the design of the radiator. When choosing a chiller, comprehensive consideration should be given to the climate conditions, water resources, energy consumption requirements and actual application requirements of the equipment in the area.
On the whole, the water cooling method has advantages in terms of heat dissipation efficiency, but in terms of energy consumption and environmental adaptability, air-cooled low-temperature chillers have more advantages. Therefore, which method to choose depends on the actual situation and needs.
