For many newly installed users, how long the service life of the air source heat pump, in addition to the installation price, is one of the concerns. At present, the service life advertised by manufacturers is generally 15 years. Through the use of more than 10 years, it is proved that there is no problem with the service life of air source heat pump of more than 10 years. Then why does the manufacturer's warranty only last for about 2 months? So what are the factors that affect the service life of air source heat pump?
Unit running time
The operating time of the unit is generally no more than 12 hours. When the operating time exceeds this time, the failure rate of the unit will increase and the service life will be affected. In the process of selection, we should listen to the Suggestions of the manufacturer and reasonably select the unit equipment.
The environment temperature
The ambient temperature can also directly affect the service life of the unit. Under the condition of low ambient temperature, a dedicated heat pump unit should be selected to ensure the normal start-up and operation of the unit under low temperature. Under the condition of the ambient temperature below -25 degrees, we should try not to use the heat pump unit for a long time.
External factors
External factors mainly refer to human factors, which are reflected in whether the installation of the unit is installed and adjusted by professional technicians. During the use, the unit should be avoided from running under high water temperature and pressure. In the winter use, we should pay attention to do a good job of anti-freeze work, when the unit is not in use, remember not to cut off the power supply, if the power supply is cut off, we need to keep the unit dry; In the unit selection and installation location, we should stay away from the smoke and leaves, so as not to beat the leaves off the wind, affecting the service life of the unit.
Start and stop times of compressor
The long life of the unit is determined by the compressor. When starting and stopping frequently, the compressor will be impacted by the over current, resulting in the low life of the unit.
