How does the industrial chiller work? What is the core system?

Release time:


The operation and work of a machine will have several core systems, so today we will talk about the core system and operation of the cold water machine.

The refrigerant circulation system of the industrial chiller is that the liquid refrigerant in the evaporator absorbs the heat from the water and begins to evaporate. Finally, a certain temperature difference is formed between the refrigerant and the water. The liquid refrigerant also completely evaporates into a gaseous state, and then is sucked in by the compressor and compressed (pressure and temperature increase). The gaseous refrigerant absorbs heat through the condenser (air-cooled/water-cooled) and condenses into liquid. After being throttled by the expansion valve (or capillary tube), it becomes a low-temperature and low-pressure refrigerant and enters the evaporator to complete the refrigerant cycle process.

The water circulation system is the water pump that is responsible for pumping water from the water tank to the equipment that the user needs to cool. The chilled water takes the heat away and the temperature rises, and then returns to the chilled water tank.

The electrical automatic control system includes the power supply part and the automatic control part.

The power supply part is to supply power to the compressor, fan, water pump, etc. through the contactor. The automatic control part includes thermostat, pressure maintenance, delay timer, relay, overload protection and other combinations to achieve automatic start and stop according to water temperature, maintenance and other functions.
