How to realize the wind speed adjustment function of the programmable constant temperature and humidity chamber

The programmable constant temperature and humidity test chamber, also known as the constant temperature and humidity test chamber, is an essential test equipment for aviation, automobiles, home appliances, scientific research, etc. We have already talked about many refrigeration systems and control systems for programmable constant temperature and humidity chambers. Electrical system, today we mainly talk about Beijing Yashilin programmable constant temperature and humidity box wind speed adjustment function What is its advantage?

(1) When the programmable constant temperature and humidity test chamber is in the heating process, the circulating fan runs at high speed, which can speed up the air convection in the working chamber, shorten the heating time and improve the working efficiency;

(2) When the temperature in the working chamber is close to the control temperature, the programmable constant temperature and humidity chamber meter automatically adjusts the circulating fan from high speed operation to low speed operation, so that the air in the working chamber is gently convected, and the life of the circulating fan is effectively extended;

(3) If the automatic wind speed adjustment function is not needed, the control parameter adjustment method can be used to adjust the high and low speed control parameters to 999.9, and the circulation fan will always be in the high speed running state.
