Problems solved by technology

Since the intensity of sunlight received by each square meter area does not exceed 1kW, it greatly limits the improvement of the heating capacity of the heat pump; in addition, since this form of evaporator has no fins, it can be used from the evaporator at night when there is no sunlight. The heat absorbed in the air is greatly reduced, resulting in a low utilization rate of the product, which can only be used to heat a small amount of domestic hot water during the day, and its heating capacity is much lower than that of an air source heat pump water heater
[0004] 2. The heat pump water heater and the solar panel are independently designed: the solar panel converts the received sunlight into alternating current through the inverter, which is used to drive the compressor, fan, and hot water cycle of the heat pump water heater pump; however, since the intensity of sunlight received by each square meter area does not exceed 1kW, and the existing photoelectric conversion efficiency is extremely low, it determines not only the huge area required by the solar panel, but also the The investment is very expensive; therefore, it is difficult to have commercial promotion value at the current state of the art

Abstract

The invention discloses a heat pump water heater driven by an air-solar hybrid source. (1) solar energy is absorbed via a reflector, a transparent blade, and a fin hohlraum, air energy is absorbed via a fin, and integrated design of a solar energy absorber and an air fin evaporator is realized; (2) an air-solar hybrid source heat pump water heater is built, and the heating capacity of the heat pump and the energy efficiency ratio are improved through improving the evaporation temperature; and (3) the solar energy is used for driving the heat pump in a high-efficiency and cheap photo-thermal conversion form, and the application threshold of the solar heat pump water heater is reduced.

Description

(1) Technical field [0001] The invention relates to an air-solar composite source-driven heat pump water heater. (2) Background technology [0002] The existing solar heat pump water heater mainly has two product forms: [0003] 1. The heat pump evaporator is designed as a solar panel absorber: it is made of double-layer aluminum plates painted black on the surface facing the light, and the distributor and circulation pipe of Freon heat pump working fluid are formed between the double-layer aluminum plates; among them, the black-coated aluminum plates are used to absorb the sun. light and provide heat for evaporation, while distributors and flow ducts are used to optimize the evaporation process in the heat pump cycle. Since the intensity of sunlight received by each square meter area does not exceed 1kW, it greatly limits the improvement of the heating capacity of the heat pump; in addition, since this form of evaporator has no fins, it can be used from the evaporator at n...
