Introduction for the High and Low temperature humidity Chamber:
High and Low temperature humidity Chamber adopts imported special man-machine interface temperature and humidity controller, which is reliable in performance, easy to operate, and the control technology has reached the current international advanced level. The cost performance is significantly better than that of similar imported equipment. Ideal equipment for alternating damp heat test. The equipment tests various materials for heat resistance, cold resistance, dry resistance and humidity resistance. It is widely use in factories of electronics, electrical appliances, food, vehicles, metals, chemicals, building materials, etc.
Application Area:
This equipment is mainly lead in LED industry. It conducts high temperature, low temperature and humidity tests on street lamps, fluorescent lamps, LED displays and other products. It simulates whether the products and materials have malfunctions, changes in quality, and cannot work normally after alternating temperature and humidity. It can meet different high and low temperature requirements.
The structure of the High and Low temperature humidity Chamber:
Standard:
Fully meet IEC60068-2-1 (GB/T2423.1) and IEC60068-2-2 (GB/T2423.2),IES LM-80-08 Standard.
Working Principle:
The working principle of refrigeration: the refrigeration cycle adopts the reverse Karro cycle, which consists of two isothermal processes and two adiabatic processes. The process is as follows: the refrigerant is adiabaticly compressed by the compressor to a higher pressure, and the consumed work causes exhaust the temperature rises, and then the refrigerant exchanges heat with the surrounding medium isothermally through the condenser to transfer heat to the surrounding medium. After the refrigerant passes through the shutoff valve adiabatic expansion to perform work, at this time the refrigerant temperature decreases. Finally, the refrigerant absorbs heat isothermally from the higher temperature object through the evaporator, so that the temperature of the cooled object is reduced. This cycle repeats to achieve the purpose of cooling down. The design of the refrigeration system applies energy adjustment technology, which 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 to keep the refrigeration system in the best operating state. Using balance temperature regulation (BTC), even when the refrigeration system is working continuously, the control system controls the output of the heater through the PID automatic calculation output according to the set temperature point, and finally achieves a dynamic balance.
