Constant temperature and humidity test chamber frosted how to solve?

Constant temperature and humidity testing-equipment' target='_blank'>test chamber is a inspection for raw materials in a variety of natural environment, features of the machinery, equipment and test all kinds of raw materials, high temperature resistant, low temperature resistant, resistant to dry, wet resistance to machinery and equipment. Universal electronics, household appliances, mobile phones, communication, instrument panel, the car, xiangsu products, metal materials, decorative materials, ingredients, organic chemistry, medical, aerospace, and other products quality inspection. Constant temperature and humidity test chamber compared with traditional environmental test chamber, more economic development, environmental protection, environmental protection and energy saving. But also has the industry, in the application process, constant temperature and humidity test chamber of the tightening machine chassis frequently, perhaps the problem of frost freezes. Encounter this kind of situation in all normal? And what should I do? Constant temperature and humidity test chamber if frosting condition, actually cannot be called a technical problem, the key point or maintenance problems. And related machinery and equipment, the quality is on the other hand, in terms of maintenance on the service life of the constant temperature and humidity test chamber plays a fundamental practical effect. According to the analysis, constant temperature and humidity test chamber iced maybe frosting condition is the key in any of the following a few big reason. The processing technology of the constant temperature and humidity test chamber tube after open, not sealing or not immediately repair. Long-term implantation of frost, and often start, moisture in the air will be from branch to go to the machine. Not sealing long-term implantation of tightening machine, not by the dry manic solution turns to frost application, also can produce ice. Damage to the constant temperature and humidity test chamber refrigeration evaporator start, will be frozen for a long time, Hide) Water vapor in the air along with the moisture in the room, to tighten machine ( Startup produce negative pressure in the evaporator, atmospheric pressure brings the moisture in wet air inside the machine) , also can produce icy conditions. Constant temperature and humidity test chamber evaporator if natural ventilation is poor, refrigerating capacity with fixed can also make evaporator frosting or frozen, then bottom pressure caused by work pressure is too low, will produce tightening machine chassis frost. Constant temperature and humidity test chamber in the normal work of all cases, the tightening machine is back in refrigerant steam instead of liquid, if the refrigeration unit cold media and refrigeration oil filling into too much or too much air conditioner expansion valve and nurse too much traffic, make the refrigerant in the evaporator not completely evaporate, causing cold media in wet steam or fluids are tightening machine back, certified public accountants to produce ice. Constant temperature and humidity test chamber tightening machine when pressurized water vapor in the air is tightened into water leakage, to introduce the line also can produce ice. Appropriate steps and timing to perform maintenance to apply for the lower machine equipment problems and abnormal situations, and related to broaden the service life of equipment is a very big help. In addition, the control WenHeng environmental test chamber in research and development in the whole process of making, should pay attention to the rationalization of design scheme. The interpretation of the above is the constant temperature and humidity test chamber frosted solution, 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!
