What is 2 ton water chiller the made of?
1. Refrigerant circulating system of LC -25°C ~ -5°C Low Temperature Chillers.
The liquid refrigerant in the evaporator absorbs the heat in the water and begins to evaporate. A certain temperature difference is formed between the refrigerant and the water.
The liquid refrigerant is also * vaporized into a gaseous state and then sucked in and compressed by the compressor (pressure and temperature increase).
The gaseous refrigerant absorbs heat through the condenser (air cooling/water cooling) and condenses into a liquid. After throttling by the thermal expansion valve (or capillary), it becomes a low temperature and low pressure refrigerant and enters the evaporator, Complete the refrigerant circulation process.
Basic composition of refrigeration system:
Compressor: compressor is the core component of the whole refrigeration system, and also the power source of refrigerant compression. Its function is to convert the input electrical energy into mechanical energy and compress the refrigerant.
Condenser: During the refrigeration process, the condenser plays the role of outputting heat energy and condensing the refrigerant.
After the high-pressure superheated steam discharged from the refrigeration compressor enters the condenser, all the heat absorbed by it in the working process, including the heat absorbed from the evaporator and refrigeration compressor and in the pipeline, is transferred to the surrounding medium (water or air) to take away.
Refrigerant high-pressure superheated vapor recondenses into liquid. (According to different cooling media and cooling methods, condensers can be divided into three types: water-cooled condensers, air-cooled condensers and evaporative condensers.)
Liquid receiver: the liquid receiver is installed behind the condenser and is directly connected with the discharge pipe of the condenser. The refrigerant liquid of the condenser should flow into the liquid reservoir without obstruction, so that the cooling area of the condenser can be fully utilized.
On the other hand, when the heat load of the evaporator changes, the demand for refrigerant liquid will also change. At that time, the liquid receiver will play the role of regulating and storing refrigerant. For the small refrigeration device system, it is often not equipped with a liquid receiver, but uses a condenser to regulate and store the refrigerant.
2. Water circulating system of 2 ton water chiller.
The water circulation system is the equipment that the user needs to cool by pumping water from the water tank. The temperature of the chilled water rises after the heat is taken away, and then returns to the chilled water tank.
3. Electric automatic control system of 2t water chiller.
The electrical automatic control system includes the power supply part and the automatic control part.
The power supply part supplies power to the compressor, fan, water pump, etc. through the contactor.
The automatic control part includes temperature controller, pressure protection, time delay device, relay, overload protection and other functions combined to achieve automatic start and stop, protection and other functions according to water temperature.
