A common problem of precision air conditioning high pressure alarm

A low supply voltage, low power supply voltage is not start up don't start is often caused by the voltage reduction or lack of phase, the power supply voltage is low, the output voltage 24 v transformer is insufficient; 24 v ac contactor can't work within the condenser. To identify specific need to use multimeter to test. When necessary, a power grid voltage regulator. Compressor fault alarm is one of the most common alarm computer room precision air conditioning, in the refrigeration system, high voltage controller is set in the 350 psig, in the operation of the machine, when the high pressure value reached the limit, high pressure alarm is generated. If you want to make the compressor to start again, must be manually reset; But before pressing the reset button, must be the cause of high pressure to find out, to make the machine working normally. Second, the compressor high pressure alarm for refrigeration system suggest that clean the condenser surface dust and dirt, but should pay attention not to damage the copper tube and fin. After maintenance also appear alarm in the system menu, maintenance cycle maintenance can eliminate the alarm. Three, humidifier refrigeration system needs to maintain it is usually caused by problems to refrigeration cycle, such as freon pressure is too low or too high, thus cause the compressor overheating, etc. To identify specific need to use pressure gauge to test.
