The auxiliary function of cold and hot impact chamber and the air circulation device are discussed
Accessory function
Impact of different temperature segments: the multi-stage evaporator structure is cut off accordingly, the evaporation area is controlled and the cooling capacity expansion valve is matched, and the output of the refrigeration system is reasonable to reduce the neutralization of the heater, so as to achieve constant energy saving; There is also an independent air exchange valve, in the exhaust (normal temperature recovery) action to introduce the ambient air inlet in the ambient temperature exposure to the outside of the air outlet from the mechanical room and test area discharge hot gas timing predetermined function preset test start time, The test chamber starts automatically and is ready to start the test. The exposure time is shortened. After the downwind temperature in the test area reaches the exposure temperature, it is transferred to the next exposure function. The low temperature tank can operate for a certain period of time under dry conditions.
Air circulator
Huanyi cold and heat shock test chamber is equipped with air conditioning room, circulating air duct and long-axis centrifugal fan. Efficient refrigerating machine and energy regulating system are used to carry out effective exchange through efficient fan to achieve the purpose of temperature change. By improving the air flow, improve the air flow and heat exchange capacity with the heater and air surface cooler, thus greatly improving the temperature uniformity of the test chamber.
