Description
Technical Field
The utility model relates to a domestic heat pump water heater's cold water moisturizing device in advance.
Background
At present, the water tank of the household heat storage type water heater adopts a pressure bearing design, a water inlet, a water outlet, a sewage discharge outlet, a temperature measuring point and the like are arranged, a heat exchanger is arranged in a common water tank for heating, although the heat exchanger is in direct contact with water, the heat exchange efficiency is high, however, the water replenishing in the using process generally occurs at a high water temperature, the temperature of a refrigerant is higher, the throttling loss is large, cold water is directly replenished into the water tank, cold water and hot water are mixed easily, the grade of the hot water is reduced, and the utilization rate is reduced.
SUMMERY OF THE UTILITY MODEL
To the above problem, the utility model provides a domestic heat pump water heater's cold water preheats moisturizing device has effectively solved the problem pointed out in the background art.
The utility model adopts the technical proposal that:
the utility model provides a domestic heat pump water heater's cold water preheats moisturizing device, includes the water tank, the lower part of water tank is equipped with cold water inlet and refrigerant export, and upper portion is equipped with hot water export and refrigerant import, the water tank in be equipped with around continuous preheat heat exchanger and inner heat exchanger, preheat the heat exchanger and be located the top of inner heat exchanger, refrigerant import and the refrigerant passageway of preheating the heat exchanger link to each other, refrigerant export link to each other with the inner heat exchanger, cold water inlet with through advance water pipeline with preheat the water passageway of heat exchanger and link to each other, the water passageway of preheating the heat exchanger extends to the bottom of water tank for the other end of advancing water pipeline through back water pipeline.
Preferably, the bottom of the water tank of the rear water inlet pipeline is provided with a plurality of water outlet spray heads, and water outlets of the water outlet spray heads are vertically upward.
Preferably, a temperature monitoring probe is arranged in the middle of the water tank.
The utility model discloses a preheat the heat exchanger and realize moisturizing cold water and refrigerant and high temperature hot water heat transfer, realize that the moisturizing cold water preheats, reinforce the heat transfer, improve the moisturizing temperature, improve the hot water utilization ratio, reduce the unit energy consumption, solved current structure water tank and caused the hot and cold water to mix, the water tank temperature descends rapidly during the use, the water yield is low, influence result of use's problem, and simultaneously, because rivers flow the heat transfer, local heat transfer coefficient has been improved, the problem that present structure water tank heating efficiency is low has been solved to the part, the unit efficiency has been improved.
