High and low temperature hot and humid alternating test chamber as a temperature control chamber, high and low temperature test chamber and high and low temperature alternating hot and humid test chamber are mainly used for industrial products, high and low temperature reliability test. The parts and materials and other related products of automobile and motorcycle, electrician, universities, scientific research units, aerospace, ship weapons and other related products in the high and low temperature (alternating) cycle changes in the circumstances, to test its performance indicators.

High and low temperature and humidity alternating chamber by the box, the wind circulation system, refrigeration systems, heating systems and humidity control system components. The air circulation system adopts the structure of adjustable air supply direction. The humidification system adopts two kinds of boiler humidification and surface evaporation. The cooling and dehumidification system adopts the air conditioning condition refrigeration structure. The heating system adopts electric heating and electric heating. Structure; temperature and humidity test method using wet and dry ball test method, but also useful humidity sensor direct measurement method; control and display the operation interface with separate temperature and humidity independent temperature and humidity combination controller and so on.

The control part of the high and low temperature and humidity alternating chamber is mainly through programmable temperature and humidity instruments. General programmable instrument, is fully automatic control, you can set the parameters and the number of tests set in advance, and then in accordance with the program set to work. Programmable temperature and humidity instrument is equipped with ordinary programmable instrument at the same time more than a waterway system control function. High and low temperature alternating hot and humid test chamber due to the refrigeration dehumidification system configuration, electrical system configuration requirements and temperature control system is basically the same.

High and low temperature and humidity alternating test chamber installation site

In order to facilitate the cooling and maintenance of the box, the installation of the equipment must meet the following conditions:

1, the distance between the adjacent walls or objects 50CM.

2, high and low temperature hot and humid alternating test chamber installation site of the ambient temperature should not drastically change.

3, should be installed on the level of the ground;

4, should be installed in the place without direct sunlight.

5, should be installed in a well ventilated place.

6, should be installed in less dusty places.

7, as far as possible installed near the power supply in the place.

8, high and low temperature hot and humid alternating test chamber should be installed away from combustibles, explosives and high temperature heat source place.

9, high and low temperature and humidity alternating test chamber In order to play the function of the test chamber, performance, should choose the annual temperature of 15 ~ 25 ℃, relative humidity less than 85% of the place.
