Air cooled chiller refrigeration cycle system is a common refrigeration equipment. Its working principle is based on the principle of refrigeration cycle system and air flow. In the refrigeration cycle, the fluid absorbs and releases heat through processes such as compression, condensation, expansion, and evaporation to achieve refrigeration. In an air-cooled chiller, air is used as the condensing medium, and the heat released by condensation is taken away by forced air flow.

Specifically, the air cooled chiller refrigeration cycle system consists of a compressor, condenser, evaporator and control system. Among them, the compressor sucks in low-temperature and low-pressure refrigerant, compresses it into high-temperature and high-pressure gas, and then sends it to the condenser. In the condenser, the refrigerant exchanges heat with the air, releasing heat into the air while the refrigerant is condensed into a liquid. Next, the refrigerant is throttled through the expansion valve, the pressure and temperature are reduced, and then enters the evaporator, where it exchanges heat with the cold water, thereby cooling the cold water. Finally, the refrigerant is sucked into the compressor and the cycle repeats.

Features of air cooled chiller refrigeration cycle system

1. Stable performance: Multiple compressors are used in parallel. Each compressor has its own independent refrigeration circuit, that is, the evaporator and condenser are also completely independent; all compressors are commanded by a unified microcomputer control system to turn on and off one by one. , will never interfere with each other, and all machines of this brand are made with original equipment, so the failure rate of a single machine is extremely low. ​

2. Power saving and energy saving: multiple small and medium-power compressors are used in parallel, which will cause minimal interference to the power grid when turning on and off. As the load changes, the unit will automatically determine the number of startups to ensure that the compressors that are turned on are in good working condition. , thereby effectively saving electric energy. ​

3. Long service life: The evaporator and condenser are very reasonably designed and placed above the compressor. During the entire operation, most of the lubricating oil always stays in the compressor, ensuring good lubrication of the compressor.
