Problems solved by technology

The disadvantage is that solar energy can only provide domestic hot water energy, and cannot participate in heating, and cannot take advantage of solar energy to produce low-temperature hot water. The circulation pipelines and control systems of the two heat sources are independent, and organic integration has not been realized.

Embodiment 1

[0035] Such as figure 1 , 3 As shown, an air source heat pump heating, cooling and hot water system includes a water storage and exchange tank 100, an air source heat pump cooling and heating unit, a water supply main pipe 600 and a return water main pipe 700, and the water supply main pipe 600 and the return water main pipe 700 are connected to the heating system. and cooling end connections.

[0036] The heat storage and exchange tank 100 includes an outer shell, an inner tank, and an insulation layer between the outer shell and the inner tank. The inner tank is divided into an upper sub-water tank 111 and a lower sub-water tank 112 via a partition 110. The upper sub-water tank 111 is provided with The heat pump medium inlet 103 and the water outlet 102, the lower sub-water tank 112 is provided with the heat pump medium outlet 104 and the water inlet 101, the upper sub-water tank 111 is provided with an upper heat exchange device 109, and the lower sub-water tank 112 is pro...

Embodiment 2

[0045] Such as figure 2 As shown, it is another air source heat pump heating, cooling and hot water system. The main difference between it and Embodiment 1 is that a solar thermal collector 200 is added, and its structure includes a solar thermal collector 200, a heat storage and exchange tank 100, Air source heat pump cooling and heating unit, water supply main pipe 600 and return water main pipe 700, the water supply main pipe 600 and return water main pipe 700 are connected to the heating and cooling terminals;

[0046] The heat storage and exchange tank 100 includes an outer shell, an inner tank, and an insulation layer between the outer shell and the inner tank. The inner tank is divided into an upper sub-water tank 111 and a lower sub-water tank 112 via a partition 110. The upper sub-water tank 111 is provided with The heat pump medium inlet 103 and the water outlet 102, the lower sub-water tank 112 is provided with the heat pump medium outlet 104 and the water inlet 10...

Embodiment 3

[0059] Such as Figure 4 As shown, the difference from Embodiment 1 is that the upper heat exchange device 109 is a coiled tube, and the lower heat exchange device 107 is a finned tube.

[0060] The two can also be interchanged, that is, the upper heat exchange device 109 is a finned tube, and the lower heat exchange device 107 is a coiled tube. It is also possible that both the upper heat exchange device 109 and the lower heat exchange device 107 are finned tubes.

[0061] Such as Figure 5 As shown, the lower heat exchanging device 107 is a heat exchanging cylinder, which has a cylindrical structure as a whole, and is provided with an inlet and an outlet, and the cylinder itself can realize internal and external heat exchange.

Abstract

The invention discloses an air source heat pump heating, refrigerating and water heating system and a control method thereof in the technical field of air source heat pumps. The system involves a heatstorage and exchange water tank, an air source heat pump cooling and heating unit, a water supply main pipe and a water return main pipe, wherein the water supply main pipe and the water return mainpipe are connected with a heating and refrigerating tail end, a heat pump medium inlet and a heat pump medium outlet are formed in the heat storage and exchange water tank, an inner container of the heat storage and exchange water tank is divided into an upper sub-water tank and a lower sub-water tank by a partition plate, and an upper heat exchange device and a lower heat exchange device are arranged in the upper sub-water tank and the lower sub-water tank respectively. The air source heat pump heating, refrigerating and water heating system can effectively solve the problems of high-pressureprotection and frequent starting in the operation of a heat pump main machine, can be further organically combined with a solar heat source, and is low in cost; and start and stop of the air source heat pump cooling and heating unit, start and stop of a heat pump circulating pump and reversing of an electric control three-way valve are controlled through temperature, the integrated control of theheating, refrigerating and water heating system is achieved, the control of the heating, refrigerating and water heating system is easy, and the maintenance is convenient.

Description

technical field [0001] The invention relates to an air source heat pump device and a control method thereof, in particular to an air source heat pump device integrating heating, cooling and hot water systems and a control method thereof. Background technique [0002] Air source heat pump heating and cooling systems are increasingly used for heating and cooling, and can provide users with heating capacity in winter or cooling capacity in summer. The system consists of an air source heat pump heating and cooling unit, a heat pump circulating pump, a buffer water tank, heating and cooling terminals and pipelines. If the user needs domestic hot water at the same time, a water tank needs to be added. Through the heat exchange tube, the water in the water tank is indirectly heated. During use, when the water temperature of the water tank is insufficient and domestic hot water is given priority, it is necessary to shut down the heating pipeline and start the heat pump to produce h...
