The principle and difference of direct heating and circulating heating of hot water heat pumpThere are two heating methods for air source hot water heat pumps: direct heating and circulating. Both methods are healthy and effective heating methods. But they are slightly different. The following Leomon Technology introduces you to the principle and difference between direct heating and circulating heating of air source hot water heat pumps.
Direct heating hot water heat pump:
The tap water is directly connected to the cold water inlet of the hot water heat pump unit, and the cold water flow is adjusted through the operation of the host and the circuit control program, so that the cold water entering the condenser of the host is heated to the set water temperature at one time (default 55 degrees can be freely Adjust), and then enter the hot water storage tank for storage. The host keeps working continuously and stops when the water level in the hot water storage tank reaches the set water level.
Circulating hot water heat pump:
The tap water is first replenished into the hot water storage tank by the water level control of the host. When the water level is higher than the minimum heating level of the hot water heat pump, the heat pump unit will start and continue to replenish cold water to the water tank. It will stop when the water level is full. The cold water in the water tank passes through the circulating water pump Operation, continuously circulates between the water tank and the host, slowly heating up, and continuously working, so that the heat pump stops working when the water temperature in the water tank reaches the set temperature.
The direct heating and circulating heating of air source hot water heat pumps are suitable for heat pumps without volume. Generally 270L uses direct heating. It is more energy-efficient to use circulatory heating above 270L. Leomon Technology is a professional manufacturer of air source hot water heat pumps.
