Control system of constant temperature and humidity test chamber

Constant temperature and humidity test chamber of the automatic control system is very important, decided to test chamber, temperature automatic control system precision, and other important indicators. Nowadays most of the controller test chamber adopts PID control, is also a small portion of the PID control method and controller design. Thermostatic oscillator due to most of the automatic control system belongs to the level of mobile phone software, and this part of the use of the whole process, the general is not easy to appear the difficulty. Cooling method of constant temperature and humidity test chamber was full of mechanical refrigeration equipment and its auxiliary liquid nitrogen refrigeration, mechanical equipment cooling steam shrink used refrigeration, their key by the refrigeration compressor, condenser, throttle valve tissue and air conditioning evaporator, ultra-low temperature stainless steel sink because everybody should do the experiment of cryogenic temperature 55 ℃, single-stage refrigeration can't conform to the requirements, thus cooling method in test chamber choose cascade refrigeration. Constant temperature and humidity test chamber is divided into two subsystems humidification and dehumidification. Constant temperature and humidity test chamber of the humidifying methods usually use wet steam, the bottom pressure steam humidifying introduction experiment indoor space design at once. This kind of humidifying method humidifying professional ability, speed faster, humidification control alert, especially in is very easy to maintain when cooling humidifying. Constant temperature and humidity test chamber of relative refrigeration system, heating system is very simple. Key composed of high-power resistance wire, because, as prescribed by the test chamber temperature speed greatly, thus the heating system output power of the test chamber relatively big, and blank in the test chamber and set up the electric heater. Constant temperature and humidity test chamber air circulation system, air dryer using the pump dehumidification is pulled out the air in the experiment box, and introduces the air dry mania, moist air will be sent to other recyclable dry, dry mania mania finished and then sent to the box, so wet cycle system. Constant temperature and humidity test chamber wiring must be correct, be sure to ground. No grounding is likely to result in electric shock accidents, incorrect posture safety accidents, has a great deviation display abnormal information or accurate measurement. Regular maintenance terminal screws and fixed bracket, please don't loose under the condition of the application. The interpretation of the above is the control system of constant temperature and humidity test chamber, hope can help you, if you want to learn more about information of constant temperature and humidity test chamber, welcome to the online consulting service or call the company service hotline ( Website top right corner) For consultation, we will wholeheartedly provide high quality service for you!
