Introduction of chemical recirculating chiller

A chemical recirculating chiller is a kind of water cooling equipment. A water chiller is a cooling water equipment that can provide constant temperature, constant flow and constant pressure. The working principle of the chiller is to first inject a certain amount of water into the water tank inside the machine, cool the water through the chiller refrigeration system, and then send the low-temperature cooling water to the equipment that needs to be cooled by the water pump. The chilled water of the chiller takes away the heat and the temperature rises. High and then flow back to the water tank to achieve cooling effect.

How chemical recirculating chiller works?

The refrigerant absorbs the heat of the object to be cooled and vaporizes into steam in the evaporator. The compressor continuously extracts the generated steam from the evaporator and compresses it. The compressed high-temperature and high-pressure steam is sent to the condenser and then The cooling medium (such as water, air, etc.) releases heat and condenses into a high-pressure liquid. After being decompressed by the throttling mechanism, it enters the evaporator, vaporizes again, and absorbs the heat of the object being cooled. The cycle continues over and over again. During heating, the refrigerant changes the flow direction of the refrigerant through the four-way valve. The flow direction of the refrigerant is just opposite to that during cooling. The refrigerant first passes through the evaporator, then returns to the condenser and then returns to the compressor.

Classification of chemical recirculating chillers

According to the compressor type: piston chiller, screw chiller, centrifugal chiller;

By fuel type: fuel type (diesel, heavy oil), gas type (kerosene, natural gas);

According to the condenser cooling method: water-cooled chiller, air-cooled water chiller;

According to the energy utilization form: single-cooling heat pump type, heat recovery type, single-cooling, ice storage dual-function type;

According to the cold water outlet temperature: high temperature type (7℃, 10℃, 15℃, 35℃), medium and low temperature type (5℃ ~ -30℃), ultra low temperature type (-30℃ ~ -120℃);

According to the sealing method: open, semi-closed, fully closed;

According to the refrigerant: water-cooled chiller, brine chiller, ethylene glycol chiller;

According to different types of energy compensation: electric power compensation (compression type), thermal energy compensation (absorption type);

By refrigerant: R22, R123, R134a, R404a, etc.;

According to different heat sources (absorption type): hot water type, steam type, direct combustion type.
