Programmable constant temperature constant humidity testing box use method and programmable constant temperature constant humidity testing box control method

Abstract

The present invention relates to the technical field of test equipment, in particular to the use method and control method of a programmable constant temperature and humidity test box. and humidity and other parameters; then close the door and observe the test object in the observation window; when the temperature in the test room is too high, the controller will control the compressor and condenser to cool down the test room; when the temperature in the test room When the temperature is too low, the controller will control the heating system to heat the test chamber. Beneficial effects of the present invention: the test system of the present invention has advanced and reasonable structural design, standardized manufacturing process, beautiful and generous appearance, and the main functional components of the test box are all equipped with world famous brands, which improves the safety and reliability of the product and can guarantee the long-term use of users. Time and high-frequency use requirements, the equipment has good operability, maintainability, good temperature stability and durability, and good safety performance.

Description

technical field [0001] The invention relates to the technical field of test equipment, in particular to a method for using a programmable constant temperature and humidity test chamber and a control method system. Background technique [0002] The constant temperature and humidity testing machine is an important test equipment in the constant temperature and humidity test of the product. It is mainly used to simulate the environmental temperature of the product. There are certain problems in the design of the existing constant temperature and humidity testing machine. There is a problem in the water supply system device. The major problems are: (1) the water supply is unstable, and the water level cannot be accurately controlled; (2) there is no alarm when there is no water; (3) due to the imbalance of air pressure, the water cannot be supplied in place.

AI Technical Summary

Problems solved by technology

[0002] The constant temperature and humidity testing machine is an important test equipment in the constant temperature and humidity test of the product. It is mainly used to simulate the environmental temperature of the product. There are certain problems in the design of the existing constant temperature and humidity testing machine. There is a problem in the water supply system device. Major problems, (1) The water supply is unstable, and the water level cannot be accurately controlled; (2) There is no alarm when there is no water; (3) Due to the imbalance of air pressure, the water cannot be supplied in place

As a result, the whole machine fails. At the same time, in terms of constant humidity, the overflow circuit cannot be well controlled, resulting in overflow problems and affecting the instability of the entire system. At the same time, the temperature control cannot be accurately controlled.

[0003] The existing constant temperature and humidity test chambers generally stop heating after the temperature of the chamber is too high to lower the temperature, so that the temperature in the chamber will continue to rise for a certain period of time, and the rate of decrease is very slow and unstable, and the control effect very poor

At the same time, it is not conducive to monitoring real-time temperature and humidity, and there is no accurate understanding of the experimental conditions, so there may be some errors in the experiment
