Example Embodiment

[0022] Example 1

[0023] like figure 1 , figure 2 , image 3 and Figure 4 shown, figure 1 In this embodiment, the solar-air dual heat source heat pump water heater includes a compressor 1, a solar-air dual heat source heat exchanger 2, a storage Hot water tank 3, throttle valve 4, hot water heat exchange coil 5 and connecting pipeline. The specific connection relationship between its components is as follows: an interface of the solar-air dual heat source heat exchanger 2 and an interface of the heat exchange coil 5 are connected through the compressor 1, and the other interface of the solar-air dual heat source heat exchanger 2 is connected. One interface and the other interface of the heat exchange coil 5 are connected through the throttle valve 4; the heat exchange coil 5 is placed in the hot water storage tank 3, and the hot water storage tank 3 is provided with a water supply port and a hot water supply port , the hot water supply pipe 11 is connected to the hot ...

Example Embodiment

[0027] Example 2

[0028] like figure 1 , Figure 5 , Image 6 and Figure 7 As shown in the figure, the difference between this embodiment and Embodiment 1 is that the solar-air dual heat source heat exchanger is of a wound fin structure, the heat exchange tube 6 is bent in an S shape, and a plurality of annular fins 7 are sleeved On the outside of the heat exchange tube, the upper and lower adjacent layers of fins are separated structures, and the single fins in the upper and lower adjacent layers of fins are aligned up and down to form an air flow channel.

[0029] In addition to the above-mentioned solutions, the various structures of the present invention can be modified in many ways. For example, the shape of the solar-air dual heat source heat pump water heater can also be in other forms, not necessarily a square shape. This can be done by changing the shape of the fins in Example 1 and the arrangement of the fins in Example 2. At the same time, The fins can also b...

Abstract

The invention discloses a solar-air dual-heat-source heat pump water heater. The water heater comprises a compressor, a heat exchanger, a hot water storage tank, a throttle valve, a hot water heat exchanging coil pipe and a connecting pipeline, wherein the heat exchanger is a solar-air dual-heat-source heat exchanger; one port of the solar-air dual-heat-source heat exchanger is connected with one port of the hot water heat exchanging coil pipe through the compressor, while the other port is connected with the other port of the hot water heat exchanging coil pipe through the throttle valve; the hot water heat exchanging coil pipe is arranged in the hot water storage tank; and the solar-air dual-heat-source heat exchanger comprises a heat exchanging pipe, fins combined with the outer wall of the heat exchanging pipe, and a solar radiation absorbing coating on the external surfaces of the heat exchanging pipe and the fins. The water heater can obviously improve the heating coefficient of performance (COP) and the running stability thereof and simplify the system composition by simultaneously using the air source and the solar radiation energy as the heat pump heat source.

Description

technical field [0001] The invention relates to a solar utilization device, in particular to a heat pump device utilizing solar energy, in particular to a solar-air dual heat source heat pump water heater. Background technique [0002] At present, energy shortage and environmental pollution have become two prominent problems restricting global sustainable development, and have attracted more and more attention from all countries in the world. The energy shortage is manifested in two aspects: on the one hand, the main body of the global energy system is “carbon-based energy”—petroleum and coal, and these non-renewable energy sources have been depleted; Waste is serious, further exacerbating the energy shortage. In addition, with the development of society and the improvement of people's living standards, energy consumption for heating, air conditioning and domestic hot water production accounts for an increasing proportion of the total energy. For this reason, vigorously de...
