Chilling Heating Circulator

Contact us today for the perfect temperature control solution

The chilling heating circulator is composed of many accessories, such as compressor, condenser, expansion valve, heat exchanger, temperature controller, circulation pump, pre-cooling unit, heating unit, refrigeration unit, etc. Each component has its own role and advantage.

Introduction to the components of chilling heating circulator

1. Compressor: The most important thing in a chilling heating circulator is the compressor. It mainly plays the role of refrigeration. It is called the heart of the unit and is a key component. A good compressor must not only operate stably, but also ensure reliable operation. Good energy efficiency.

2. Evaporator and condenser: The evaporator and condenser play the role of absorbing and releasing heat respectively. Sufficient and appropriate heat exchange can give full play to the efficiency of the compressor. If the heat exchange of the condenser is insufficient, it will directly Affects the refrigeration effect of the unit. In summer, high pressure is prone to occur, and even excessive high pressure may cause the cooling and heating cycle unit to shut down for protection. The heat exchange rate of the evaporator is more important. Insufficient heat exchange will not only cause low efficiency of the unit, but also cause severe under-efficiency. The refrigerant cannot completely evaporate and returns directly to the compressor, causing liquid shock and damaging the compressor, thus making the entire cooling and heating cycle unit unusable.

3. Expansion valve: The expansion valve is both a flow regulating valve in the chilling heating circulator and a throttle valve in the refrigeration equipment. Its main function is to throttle and reduce the pressure of the high-pressure and normal-temperature refrigerant liquid when it flows through the thermal expansion valve. The wet vapor of low-temperature and low-pressure refrigerant enters the evaporator, vaporizes and absorbs heat in the evaporator, and achieves the purpose of cooling and cooling.
