The floor is designed with a drainage tank,and the test chamber has no water inside after the end of high temperature and humidity test Conventional constant humidity method: When the actual temperature reaches the set temperature, the compressor's cooling capacity remains unchanged, and the heating method is used to offset the compressor's cooling capacity to achieve temperature balance in the box.
Cold balance method: When the actual temperature reaches the set value, the cold solenoid valve output is controlled by the controller PID, and the temperature in the box is balanced through the controlled cooling output. Compared with the conventional constant humidity method, the heating output is reduced to make the whole unit Compared with the conventional method, the equipment can achieve 40% energy saving

Freezing and dehumidifying by the refrigeration system (the air in the box passes through the evaporator below the dew point temperature, and water is precipitated).
*Choose evaporator fins with hydrophilic membrane treatment, better dehumidification performance, because the water tension of the hydrophilic membrane aluminum fins is small, the water droplets from air condensation are easy to slip off, and it is not easy to produce obstructive water bridges in the fin gap. Thereby greatly improving the dehumidification efficiency!
