How to maintain the Temperature Humidity Chamber

1.  Cleaning and maintenance inside and outside the Temperature Humidity Chamber
①. Before the high and low temperature test, the internal impurities must be removed.
②. The power distribution room shall be cleaned at least once a year, and the indoor dust can be removed by vacuum cleaner after each cleaning.
③. The surface of the chamber shall be cleaned and wiped more than once a year.

2. Check and maintain the humidifier of Temperature Humidity Chamber
In order to ensure clean water quality, the water in the humidifier should be replaced once a month. The humidifier should be cleaned once a month to ensure smooth water flow.

3. Check the overheat protector
During the operation of Temperature Humidity Chamber, the set temperature of overtemperature protection is 20~30 ℃. After the temperature in the test chamber rises to the over-temperature protection setting value, the power supply of the heater will stop immediately. The overtemperature alarm light is on, but the electric fan is still on. In case of long-term operation and unattended, please check whether the over-temperature protection is set before operation.

4. Condenser dust collection of Temperature Humidity Chamber
The capacitor shall be regularly maintained every month, and the capacitor shall be sucked by vacuum pipette or high pressure air as required.

5. Replace the cloth for wet bulb test
After the surface of the cloth test material is not clean or hard, or the temperature control work is completed, the cloth test must be replaced before continuing to control the temperature and humidity. Replace the test cloth every three months. When changing the cloth, use a clean cloth as the temperature measuring body. When changing the test cloth, clean it first.

6. Inspection and adjustment of wet bulb water level
The water level of the ponding tank should not be too high, so that the water overflows the tank or is too low, so that the water absorption of the wet bulb test cloth is abnormal, and the water level that affects the wet bulb accuracy can be maintained above 6 points. The water level of the bucket can be adjusted, and the water level of the ponding point can be adjusted.

Basic preconditions for operation of Temperature Humidity Chamber
1. When the equipment is running, please do not touch it directly with your hand, otherwise the operator may get an electric shock or be injured by an electric fan, causing risks.

2. During the operation of the Temperature Humidity Chamber, it is forbidden to turn off or turn on the water chiller within 15 minutes. Unless there are special requirements, the light must be turned off at any time.

3. When the equipment is running, open the door of the chamber, or the following results will be caused: high temperature and humidity will rush out of the box; If the door of the equipment is kept at high temperature, the high temperature air will cause fire; The switch chamber of the equipment is damaged to the compressor during the test, and the design requirements are necessary, otherwise the user is not recommended to open and close the chamber door during the test.

4. The installation direction of wet ball gauze in the Temperature Humidity Chamber shall be accurate, so as to measure the accurate relative humidity. The circuit breaker and overtemperature protector of the equipment provide the machine with test commodities and environmental protection for the operator. It needs to be checked regularly and regularly. When completing a low temperature operation, the temperature range should be 60 ° C for analysis and boring skills. The door of the tank should be opened after about half an hour, so as to avoid affecting the measuring time of the later test or icing of the evaporator.

5. It is not allowed to repair and check the equipment if it is not a professional operator. Because during the inspection, there must be professional personnel to discuss, and professional electricians or circuit maintenance personnel must be together, so that the uninformed operators can switch on and off, and then spread the risk of electric shock.
