Function description of hot and cold temperature impact test chamber

Product function: impact at different temperature sections: correspondingly cut off by the multi-stage evaporator structure, control the evaporation area to match the cooling capacity expansion valve, use the output of the cooling system to reasonably reduce the output of the heater neutralization, and achieve constant energy saving; There is also an independent ventilation valve, which acts to introduce ambient air during exhaust (normal temperature recovery).

a. The air inlet sucks in the outside air when the ambient temperature is exposed.

b. The exhaust port discharges the hot air from the mechanical room and the test area to the scheduled function.

c. Pre-set the test start time, the test chamber will automatically start and prepare to start the test.

d. Exposure time shortening function.

e. The function of switching to the next exposure after the downwind temperature of the test area reaches the exposure temperature.

f. Pre-processing/post-processing functions.

g. Before or after the cycle test begins, the sample is exposed to a high temperature environment (heat treatment) for a certain period of time.

h. Dry running function.

j. Run for a certain time under the test result.

The hot and cold temperature impact test chamber is divided into three-box type and two-box type according to the test requirements and test standards. The difference lies in the test method and internal structure. The three-box type is divided into a cold storage room, a heat storage room and a test room, and the product is placed in the test room during the test. The two-box type is divided into a high-temperature room and a low-temperature room. The high and low temperature switching is realized by driving the movement of the basket by the motor. The product is placed in the basket and moves with the basket.
