A recirculating chiller or heater is a device that transfers low-temperature heat energy or high-temperature heat energy into high-temperature heat energy or low-temperature heat energy. It includes two parts, the refrigeration cycle and the heating cycle, which are used to realize the functions of cooling and heating respectively.

In the refrigeration cycle, the refrigerant absorbs the heat in the room and discharges it to the outside through the steps of compression, condensation, expansion and evaporation. In this way, the temperature in the room can be lowered to achieve the purpose of cooling.

In the heating cycle, the working medium absorbs external energy through combustion or electric heating, and then transports the heat to the place that needs to be heated through heat transfer. In this way, the temperature in the room can be raised to achieve the purpose of heating.

Recirculating chiller or heater is widely used in various fields of life, such as air conditioners, refrigerators, water heaters, heaters and so on. It can not only improve our living comfort, but also save energy, and has a positive effect on environmental protection.

A recirculating chiller or heater is a device used to change the temperature of an object. Its working principle is to absorb heat energy (high temperature heat energy or low temperature heat energy) in a certain place first, and then transfer the heat energy to another place, so as to achieve the effect of heating or cooling.

A recirculating chiller or heater is mostly composed of a compressor, an evaporator, a condenser, and an expansion valve. Among them, the compressor is mainly used to increase the pressure of the refrigerant to increase its temperature; the condenser is used to transfer the heat in the refrigerant to the external environment; the expansion valve is used to adjust the flow of the refrigerant and pressure; while the evaporator is used to absorb the heat in the room and transfer it to the refrigerant, thereby reducing the room temperature.

The application range of recirculating chiller or heater is very wide, covering various fields. For example, household appliances such as air conditioners, refrigerators, water heaters, and heaters all use refrigeration and heating cycle devices to achieve the effect of temperature control; in industrial manufacturing, agricultural production, medical and health and other fields, refrigeration and heating cycles are also required device.

The operation of recirculating chiller or heater can not only improve our quality of life, but also play an important role in protecting the environment and saving energy. Therefore, it is the general trend to develop and promote refrigeration and heating cycle devices.
