Common problems with high-pressure alarms in high-precision constant temperature and humidity air conditioners
Release time:
2020-03-12
High-precision constant temperature and humidity air conditioner low power supply voltage does not start often due to voltage reduction or phase loss, low power supply voltage, resulting in insufficient output voltage of 24v transformer; 24v AC contactor in condenser cannot work. Specific needs to be tested and determined with a multimeter. If necessary, a power grid voltage stabilizer is equipped.
1. Low power supply voltage does not start
High-precision constant temperature and humidity air conditioner low power supply voltage does not start often due to voltage reduction or phase loss, low power supply voltage, resulting in insufficient output voltage of 24v transformer; 24v AC contactor in condenser cannot work. Specific needs to be tested and determined with a multimeter. If necessary, a power grid voltage stabilizer is equipped.
Compressor failure alarm is one of the most common alarms of high-precision constant temperature and humidity air conditioner. In the refrigeration system, the high-pressure controller is set at 350psig. When the high pressure value reaches this limit during machine operation, a high-pressure alarm is generated. To restart the compressor, it must be manually reset; but before pressing the reset button, the cause of the high pressure must be found to make the machine run normally.
2. Compressor high-pressure alarm
For the refrigeration system, it is recommended to clean the dust and dirt on the surface of the condenser, but be careful not to damage the copper tube and fins. If the alarm still appears after maintenance, you can perform maintenance in the system menu, high-precision constant temperature and humidity air conditioner maintenance cycle to eliminate the alarm.
3. Humidifier refrigeration system needs maintenance
High-precision constant temperature and humidity air conditioners are usually caused by obstacles in the refrigeration cycle, such as excessive Freon pressure, too low pressure, or the resulting compressor overheating. The specific need to be tested and determined with a pressure gauge.
