The constant temperature and humidity test box is mainly composed of a box body, a wind circulation system, a refrigeration system, a heating system and a humidity control system. The air circulation system generally adopts a structure that can adjust the direction of air supply; the humidification system adopts two types of boiler humidification and surface evaporation; the cooling and dehumidification system adopts an air conditioning working condition refrigeration structure; the heating system adopts electric heating fin heating and electric furnace direct heating. Structure; temperature and humidity test method adopts dry and wet ball test method, and also uses humidity sensor direct measurement method; control and display operation interface adopts temperature and humidity separation independent and temperature and humidity combination controller.
The constant temperature and humidity test box mainly consists of constant temperature and humidity, and can also be said to be a high and low temperature damp heat test box. The constant temperature and humidity test box is mainly used for constant temperature and constant humidity detection of industrial products and obtains relevant data of reliability. At present, it is widely used as a high-level and low-temperature alternating cycle test for high-level and low-temperature alternating materials, such as electronic and electrician, automobile motorcycle, aerospace, and ship weapons, as well as related scientific research units.
  In the process of using, we can use the CNC machine tool in the equipment to carry out related operations. There are no relevant reaction handles in the shape. In addition to the beautiful appearance, the important point of Zui is that it is easy to operate. The liner is made of high-grade stainless steel mirror panel. Sprayed with A3 steel plate. A large observation window with built-in tempered glass in the heating body is attached to the illuminator to keep the box bright, so that the operator can clearly observe the test situation in the box at any time.
  1. The temperature around the fuselage of the constant temperature and humidity test box should be kept clean at all times;
  2. The machine should remove the internal impurities (objects) before operation; at least once a year in the laboratory;
  3. When opening or closing the test object from the box, do not allow the item to come into contact with the door seal;
  4. When the product is taken after the time of the test product arrives, the product must be picked up and put in the off state;
  5. The refrigeration system is the core of the constant temperature and humidity test chamber. It is necessary to inspect all copper pipes for leaks once every six months. All functional joints and welded joints must be disposed of immediately if there is any oil spill.
  6. The condenser should be regularly maintained and kept clean. Dust-adhesive condenser will cause the compressor high-voltage switch to trip and cause false alarm. The condenser should be regularly maintained monthly. Use the vacuum cleaner to remove the dust attached to the condenser heat-dissipating mesh or use a hard brush after booting. Brush or use a high pressure nozzle to blow clean dust;
  7. At the end of each test, it is recommended to clean the test chamber with clean water to keep the equipment clean; after the cabinet is clean, the box should be dried to keep the box dry;
  8, circuit breakers, over-temperature protectors, provide the test products of this machine and the operator's safety protection, so please check regularly.
  When operating in a constant temperature and humidity test chamber , do not open the door, unless it is necessary to open it, otherwise it may cause these adverse consequences: high temperature moisture impacts the outside of the box; the inside of the door still maintains high temperature; high temperature air may The fire alarm is triggered to cause a mistake; during the experiment, the switch box has certain damage to the compressor. Unless the test requires, it is not recommended to switch the door frequently during the experiment.
