Detailed Description
To further illustrate the embodiments, the present invention provides the accompanying drawings. The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the embodiments. With these references, one of ordinary skill in the art will appreciate other possible embodiments and advantages of the present invention. Elements in the figures are not drawn to scale and like reference numerals are generally used to indicate like elements.
The present invention will now be further described with reference to the accompanying drawings and detailed description.
The embodiment provides a heating defrosting air source hot water pump, which comprises a heat pump unit, wherein the heat pump unit comprises a heating circulating pipeline, a plurality of first condensers are arranged on the heating circulating pipeline, and the first condensers are connected to the heating circulating pipeline in parallel and are arranged indoors to form an indoor air conditioning unit for supplying heat.
Referring to fig. 1, the heat pump unit of this embodiment is further connected to a water module 11 through a heat exchanger 2.
The water module 11 includes a water supply pipe and a water return pipe connected to the heat exchanger 2 to output hot water and inject cold water, respectively.
The heat exchanger 2 is internally provided with a second condenser which is also connected to a heat circulation pipeline of the heat pump unit in parallel. Under the normal heating condition, the second condenser supplies heat to the outside; after the evaporator of the heat pump unit heats and defrosts, the temperature of water in the heat exchanger can be reduced due to the temperature reduction of the second condenser.
Therefore, one end of the first condenser is also provided with a first electronic expansion valve, and the first electronic expansion valve is opened at a large angle under the heating defrosting mode, so that the first condenser completes refrigerant circulation; meanwhile, a second electronic expansion valve 21 is further disposed at one end of the second condenser, and at this time, the second electronic expansion valve 21 is closed, so that it is ensured that the low-temperature refrigerant cannot flow into the heat exchanger 2.
Preferably, the second electronic expansion valve 21 is disposed on a liquid pipe of the second condenser, and meanwhile, a filter is disposed on each of two end pipes of the second electronic expansion valve 21 to complete the filtering. As can be seen from fig. 1, a temperature sensor and an electric water outlet control valve are further arranged at one end of the water supply pipe close to the heat exchanger, the temperature sensor is electrically connected with the controller, so that water outlet can be timely cut off when low-temperature/superheated water flows out, water supply safety is ensured, and a function of supplying water again after the water temperature is qualified after reheating after defrosting.
While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
