Xenon lamp aging test chamber refrigeration system working status

The inspection of the refrigeration system of the xenon lamp aging test box not only requires the maintenance personnel to have a high theoretical knowledge, but also judges whether the refrigeration system of the test box is in working condition. 1, refrigeration system compressor The refrigeration system compressor has a buzzing sound and a slight vibration during normal operation. The exhaust pipe is hot and the return pipe is frozen. When cooling, it is generally condensed and boiled. There may be a slight frost during heating, and the compressor has an overload protector. When the compressor is at high temperature and over current, The protector is disconnected and the internal circuit of the compressor is cut open. When the temperature is normal, the protector will automatically close. 2. Refrigeration system indoor and outer heat exchangers When the refrigeration system is refrigerated, the inlet of the exchanger outside the test will be very hot, the temperature at the outlet will be reduced, the indoor heat exchanger will freeze hands, and the surface of the ear fins will have a condensed water path. When the heating is performed, The outdoor exchanger will be very cold and may have frost, and the indoor heat exchanger will be hot.
