Dongguan high and low temperature

Dongguan high and low temperature 
 Constant temperature and humidity testing machine 
 Instrument uses: 
 Constant temperature and humidity testing machine, also known as environmental testing machine, experiment with various materials, heat, cold, resistant to dry, the moisture performance. Suitable for the use of electronics, electrical appliances, food, vehicles, metal, chemical, building materials factory quality control. 
 How it works: 
 The operation of the machine system of humidity humidity cycle through three interrelated systems: the refrigerant circulating system, air circulation systems, electrical automatic control system; 
 The refrigerant cycle system: 
 Evaporator liquid refrigerant absorbs the heat of the air (air cooling and dehumidification) and evaporation, and ultimately between a certain temperature, the liquid refrigerant is completely evaporated into gaseous refrigerant and empty after the compressor inhalation and compression (pressure and temperature increase), the gaseous refrigerant to absorb heat through the condenser (air / water), condenses into liquid. Through the expansion valve (or capillary) throttled into low temperature low pressure refrigerant into the evaporator to complete the refrigerant cycle. 
 Air ring system: 
 Fan is responsible for the air from the return air inhalation, air passes through the evaporator (cooling, dehumidification), humidifiers, electric heaters (heating) outlet sent to the space required by the user, the outgoing air and space air mixing and returned to the return air. 
 Electrical automatic control system: 
 Including the power part and the automatic control section. 
 Power in part through the contactor, compressor, fan, power adder, humidifiers, and other power supply; automatic control sub-section is divided into the part of the temperature and humidity control and fault protection; temperature and humidity control by temperature, humidity controller the return air temperature and humidity with the user-set temperature and humidity for comparison, automatically run the compressor (cooling, dehumidification), humidifiers, electric heating (warming) and other components to achieve a constant temperature and humidity automatically controlled; fault protection control mutual combination of protection by pressure, time delay relays, overload protection of fault protection control, compressor, fans, humidifiers, and other components.
