Air source water heater maintenance phone number 64933511 in Sheshan Town, Songjiang District, Shanghai

Air source heat pump water heater repair center in Sheshan Town, Songjiang District, Shanghai Analysis and solutions on five common problems of heat pumps Symptom 1: The set water temperature cannot be reached or the temperature rises slowly, but some engineering units run much longer than the design time The water temperature still cannot be reached, and the hot water can only be used directly or even cannot be used. The measured temperature is around or lower. The system's ring pump keeps ringing, and the temperature does not rise. Symptom 2: The unit works for too long, running continuously for more than an hour, and the electricity consumption greatly exceeds the budget given by the merchant to the customer. The cost increases or the expected use of the valley electricity price discount plan is meaningless, and the customer's trust in the air source heat pump hot water unit is greatly reduced. , and even proposed cost compensation. Overloading of power distribution components and increased circulation in waterways caused by long continuous operation of the unit will inevitably lead to a series of chain system problems. Symptom 3: The unit freezes when it is cold and cannot be started


When the temperature drops below ℃, the entire system enters a shutdown state. Even if the temperature rises, it still cannot start running, or the outside of the machine The fan rotates and the compressor stops working.

Symptom 4: The refrigerant ring pipe bursts, the refrigerant is lost, and the whole machine is paralyzed


The performance is that after continuous operation or starting for a period of time, the noise of the outdoor main unit becomes louder, and the local There was a crack in the refrigerant return pipe, and the refrigerant leaked out, and the pressure test was zero. Sometimes the fan can rotate, the water temperature does not change, and the resistance of the compressor when tested with a multimeter is extremely small.


Symptom 5: The outdoor unit is severely frosted and the heating effect is seriously insufficient


It may even crash due to frost or the defrost time may take up More than % of the unit's running time will cause the heating capacity of the entire unit to decrease and the power consumption to increase.
