The cooling and heating circulator is a temperature control device for refrigeration and heating used in the fields of medicine, chemical industry, laboratory, scientific research, industry and production. It can control the temperature within a temperature range to meet the experimental temperature requirements of various applications.
1. The principle of cooling and heating circulator:
The cooling and heating circulator usually adopts a compression cycle refrigeration system, which is mainly composed of a compressor, a condenser, an expansion valve and an evaporator, etc., which can circulate the refrigerant to absorb and release heat, thereby realizing the process of cooling or heating.
When the temperature is lower than the set temperature, the refrigeration system of the cooling and heating circulator starts, and the compressor compresses the low-temperature refrigerant to form a high-temperature and high-pressure refrigerant, which dissipates heat through the condenser and turns it into a low-temperature refrigerant, which expands through the expansion valve And enter the evaporator, absorb heat in the evaporator to achieve refrigeration. When the temperature is higher than the set temperature, the heater starts to heat through the heating element, thereby increasing the temperature. The heating principle of the heater is opposite to the cooling principle of the refrigerator.
The cooling and heating circulator can control the temperature of the device and keep it constant, the user can set the desired temperature, and monitor and control the temperature of the device through the built-in sensor. The cooling and heating circulator can be used in different environments and adapted to various needs.
2. Application fields of cooling and heating circulator:
1） Laboratory: It can be used in chemical experiments, biological experiments, medical experiments and other fields in the laboratory, and can meet the constant temperature requirements of different experiments.
2） Chemical industry: Accurate temperature control is required in the production of chemical products, which can meet the temperature control needs of various chemical industry production fields.
3） Food industry: It can be used in food processing to ensure the quality and safety of food.
4） Electronics industry: Accurate temperature control is required in the manufacturing process of circuit boards, and this requirement can be met.
