Energy-saving and environment-friendly programmable constant temperature and humidity test machine

Abstract

The invention provides an energy-saving and environment-friendly programmable constant temperature and humidity test machine, which comprises a box body, and an air circulation device, a heating device, a humidification device, a refrigeration device and a temperature adjustment device which are arranged in the box body; a test chamber and an equipment chamber are arranged in the box body, the heating device, the humidification device, the refrigeration device and the air circulation device are all arranged in the test chamber, the temperature adjustment device comprises a circuit device and apower pump connected onto the circuit device, the power pump guides normal temperature gas or liquid into the circuit device, and heat in the test chamber is taken out of the test chamber by the normal temperature gas or liquid. The temperature in the test chamber is adjusted and controlled by adding the temperature adjustment device, thereby increasing the dew point temperature, to reduce the dehumidification capacity, achieve high temperature and high humidity long-term testing, reduce the loss of electrical energy and water by the heating device and the humidification device, as well as carbon dioxide emissions, and achieve the effects of energy saving and environment protection.

Description

technical field [0001] The invention relates to a testing device, in particular to an energy-saving and environment-friendly programmable constant temperature and humidity testing machine. Background technique [0002] The environmental testing machine is composed of heating, humidifying and cooling devices, which can adjust the temperature and humidity in the test room to the state to be tested, so as to test the temperature and humidity resistance of products in different environments. Among them, the humidifying device of the customary testing machine usually sets a water tray filled with water in the testing room, and uses a heater to heat the water into water vapor to increase the relative humidity in the testing room. The relative temperature of the room. [0003] When the test temperature and humidity of the test room need to be constant within a certain area, the traditional method is to use compressor refrigeration to suppress the temperature in the test room, and ...
