Factors affecting the stability of the constant temperature and humidity test chamber

The reliability of the constant temperature and humidity test chamber half from manufacturers design scheme, it is the customer in the application can't change; The other half is the set of the whole application process, this is the ability to manipulate by the customer. Equipment good and not so good, most is how you use, but most of the factory is no professional skills training and using of the only, according to a paper instructions in the actual operation is difficult to reach ideal situation. Referring to the reliability of the constant temperature and humidity test chamber, will have to talk about constant temperature and humidity test chamber refrigeration unit. Most can application in the constant temperature and humidity box unipolar refrigeration cycle USES the temperature in the media is the R404A, the evaporating temperature is at a pressure - 46. 5 ℃, but evaporative cooling type cooler heat transfer temperature difference generally take 10 ℃, only made - in other words in the box 36. Ultra-low temperature of 5 ℃, so in order to get a lower temperature requirements? This time can through reduce the volatilization of refrigeration compressor working pressure, can reduce the least volatile temperature of the refrigerant to - 50 ℃, hence to obtain - Ultra-low temperature of 50 ℃, and the following must be used when temperature in medium and low temperature medium cascade refrigeration cycle, it can ensure the constant temperature and humidity test chamber refrigeration reliability. Constant temperature and humidity test chamber refrigeration unit and the refrigerating compressor is complementary to each other, unipolar least volatile temperature steam to reduce the refrigeration unit, doubt is the key to its cold working pressure and engine compression ratio. All the refrigerant, evaporating temperature is lower, is also the less volatile working pressure. When evaporating temperature is too low, some common cold media has reached condensation temperature, and can't complete the refrigerant activity, the theme of the circulatory system. Volatile working pressure decreases, the volume of refrigerant, refrigerant mass flow is reduced, the time needed to get air conditioning refrigerating capacity, must expand the breathing capacity, excessive large refrigeration compressor volume. Constant temperature and humidity test chamber temperature reduction and wet all by refrigeration unit, the same system software makes equipment arrived in two different situations, it's all about people to the actual operation, so the accurate setting of constant temperature and humidity test chamber work system software is critical, effective application of appropriate, will be able to reach you want results. The above explanation is the factors influencing the stability of the 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!
