It is suitable for damp heat tests of various small electrical appliances, instruments, materials and components. It is also suitable for aging tests. The test box adopts the most reasonable structure and stable and reliable control method, so that it has beautiful appearance, simple operation, safety, high precision of temperature and humidity control, and it is an ideal equipment for constant temperature and humidity test.
(1) The test box body is in the form of a whole structure, the refrigeration system is located at the lower part of the box, and the control system is located at the upper part of the test box.
(2) In the air duct interlayer at one end of the working chamber, distributed heaters, refrigeration evaporators, blades and other devices; the left side of the test box is provided with 电缆50 cable holes, and the test box is a single-open door (stainless steel embedded door handle)
(3) Double-layer high temperature resistant anti-aging silicone rubber seal can effectively guarantee the loss of test chamber temperature
(4) The door is provided with an observation window, an anti-frost device and a switch-controlled lighting. The observation window is made of multi-layer hollow tempered glass, and the inner glued sheet type conductive film is used for heating defrosting. The lighting lamp adopts the imported brand Philips lamp, which can effectively observe the test changes in the working room.
The temperature regulation and humidity conditioning refrigeration cycle adopts an inverse card cycle, which consists of two isothermal processes and two adiabatic processes. The process is as follows: the refrigerant is adiabatically compressed to a higher pressure by the compressor, and the consumed power is discharged. The temperature of the gas rises, and then the refrigerant is heat-exchanged with the surrounding medium through the condenser to transfer heat to the surrounding medium. After the refrigerant is adiabatically expanded by the shut-off valve, the temperature of the refrigerant is lowered. Finally, the refrigerant absorbs heat from the higher temperature object isothermally through the evaporator, so that the temperature of the object to be cooled is lowered. This cycle is repeated to achieve the purpose of cooling.
The design of the refrigeration system of the test chamber applies energy regulation technology, which not only ensures the normal operation of the refrigeration unit, but also effectively adjusts the energy consumption and cooling capacity of the refrigeration system to keep the refrigeration system in an optimal operating state. Balanced temperature regulation (BTC) is adopted. When the refrigeration system is in continuous operation, the control system controls the output of the heater according to the result of the PID automatic calculation output according to the set temperature point, and finally achieves a dynamic balance.
