The constant temperature and humidity machine mainly provides testing environment and test conditions such as electronic parts, industrial materials, finished products in the tests of all aspects of research and development, production and inspection., Rubber, toys, and other industries.
Constant temperature and humidity machine repair
1. High -pressure alarm in the refrigeration system ① Instead of heat dissipation, install the appropriate power air conditioner to cool down or open doors and windows at the equipment use site to make the air flow.② The refrigeration system is blocked, the blocking point is found, the drying filter is replaced, the refrigerant identified by the compressor is added, and the debugging.③ The condensed fan is damaged and the condenser fan is replaced.2. Compressor overcurrent alarm ① poor heat dissipation.② The compressor is damaged and replaced the compressor of the same model (preferably the same brand).③ Excessive protectors abnormal, overcurrent protection damage, or poor debugging causes the current setting value to shrink.
Principle of constant temperature and humidity machine
The constant temperature and humidity machine consists of a refrigeration system, heating system, control system, humidity system, air supply circulation system, and sensor system. The above systems are divided into two aspects of electrical and mechanical refrigeration.Here are the working principles and work processes of several main systems.1. Refrigeration system: Refrigeration system is one of the key parts of the constant temperature and humidity machine.Generally speaking, the refrigeration method is mechanical refrigeration and auxiliary liquid nitrogen refrigeration. Mechanical refrigeration uses steam compressed refrigeration. They are mainly composed of compressors, condenser, throttle, and evaporator.If the temperature of our test must reach -55 ° C, the single-stage refrigeration is difficult to meet the requirements, so the refrigeration method of the constant temperature and humidity machine generally uses a folded refrigeration.The refrigeration system of the constant temperature and humidity machine consists of two parts, which are called high -temperature and low -temperature parts. Each part is a relatively independent refrigeration system.
