Causes of abnormal frost formation in air source heat pumps
. When the outdoor ambient temperature is greater than ℃, condensation water on the surface of the radiator fins on the entire heat exchanger will condense into thin frost soon after the power is turned on. The frost will soon become thicker and thicker. The indoor heating effect is poor and defrost occurs frequently. This fault is generally caused by the surface of the radiator fins on the outdoor heat exchanger being dirty and blocked, the outdoor fan system failing, or obstructions at the inlet and outlet of the outdoor heat exchanger.
.The outdoor ambient temperature is higher than ℃. Shortly after the startup, the bottom of the outdoor heat exchanger (starting from the capillary outlet and the heat exchanger inlet) is frosted very thickly. Most of the heat exchanger has no condensation water. Over time, frost will form from the bottom. The indoor fan is always running at low speed to prevent cold wind and the air conditioner is frequently defrosted.
.The outdoor ambient temperature is higher than ℃. Shortly after starting the machine, the upper half of the outdoor heat exchanger (the heat exchanger outlet and the return pipe) is frosted very thickly, and the frost accumulates on the heat exchanger over time from top to bottom (with the exchanger The frost is spreading (direction from the heater outlet to the heat exchanger inlet) and the heating effect is poor. The air conditioner defrosts frequently. This fault usually occurs when there is too much refrigerant in the system and often occurs after adding refrigerant during maintenance.
What are the effects of frost on air source heat pumps?
.Block the passage between fins to increase air flow resistance
.Increase the thermal resistance of the heat exchanger and reduce the heat transfer capacity
.Frequent defrosting and insufficient defrosting. The defrosting process is not only an air conditioning operation process, It cannot make hot water and at the same time it needs to consume the energy of the original hot water. The discharged frozen water rushes back into the insulated water tank, causing the water temperature to drop further
. The evaporation temperature decreases and the energy efficiency ratio decreases. The operating performance of the heat pump deteriorates until it cannot work normally.
.Because the unit cannot work properly, it will directly cause economic losses to customers, and even cause fear of heat pump products, which will affect their consumption choices.
Air source heat pump defrosting method
You can increase the fan speed to increase the exhaust air volume. The frosting process is that the steel pipe is frosted first, then the evaporator fins are frosted, and then the inside of the evaporator is frosted.
As the heat exchange area increases, the temperature difference between the evaporation temperature and the ambient temperature will be relatively small, and frost will not easily form.
Use a small circulation system to give the unit a rest. Reducing the defrost time can ensure that the hot water storage tank has hot water of sufficient temperature and improve the energy efficiency ratio, but the cost will increase.
