What is the effect of frost on the air source heat pump?
Block the passage between the fins and increase the air flow resistance.
Increase heat resistance for heat exchanger and decrease in heat exchange.
3. Frequent frost, the frost of frost process is an air-conditioning running process, not only can't hot water, also need to consume the old hot water energy consumption at the same time, the discharge frozen water recoil in the heat preservation water tank, water temperature decline further;
The evaporation temperature drops, the efficiency ratio decreases, the heat pump performance deteriorates until it is not working properly.
Because the unit is not able to work properly to cause economic loss directly to the customer, until it produces the fear of the heat pump product, affect its consumption choice.
Air source heat pump defrosting method:
It can increase the fan speed, increase the air quantity, the frost process is the steel pipe frosting, the rear evaporator fins, and the inside of the evaporator.
The temperature difference between evaporation temperature and ambient temperature is relatively small when the heat transfer area is increased, and the frost is not easy.
3, use the small circulation system to get the crew to rest. Reduce the amount of time it takes to melt the cream, and ensure that the heat storage tank has enough hot water to warm the water, and make sure that it increases the energy efficiency, but the cost increases.
