We all know that the high and low temperature test chamber is the most widely used test equipment in environmental testing equipment, and its compressor is an important part of the high and low temperature test chamber. How to make the high and low temperature test chamber play a greater role, we need to understand the high and low temperature test Relevant analysis of the box compressor and the introduction of its role. The high and low temperature test chamber adopts the French "Taikang" fully enclosed refrigeration compressor unit, each unit is monitored by the European "Taikang" computer network item by item and has an anti-counterfeiting code, which can be searched on the Internet through the computer; The cooling rate and the requirement to reach the lowest temperature. The connecting container is an evaporative condenser. The function of the evaporative condenser is to use the low-pressure circulation evaporator as the high-pressure circulation condenser; the design of the refrigeration system should have energy adjustment technology. An effective treatment method can not only ensure the normal operation of the refrigeration unit, but also effectively adjust the energy consumption and cooling capacity of the refrigeration system, and reduce the operating cost and failure rate of the refrigeration system to a more economical state; Refrigeration auxiliary parts: air-cooled coil condenser, fin-type multi-stage evaporator, the main refrigeration accessories and control devices are imported originals, such as: American "Danfoss" thermal expansion valve, American "Aigao" drying filter; Italy "Castor" solenoid valve; refrigerant: refrigerant R502 (low pressure cycle); cooling method: air cooling The high and low temperature test chamber compressor uses a new type of PWM cold control technology to achieve low temperature energy-saving operation: low temperature working state, the heater does not participate in the work, PWM technology is used to adjust the refrigerant flow and flow direction of the refrigeration unit, the cooling pipe, cold bypass pipe, heat The three-way flow adjustment of the bypass pipe realizes the automatic constant temperature of the working room. This method can reduce energy consumption by 40% under low temperature conditions.
