Description

Technical Field

[0001] The invention relates to the field of air source heat pump defrosting and discloses an air source heat pump heat storage defrosting device combined with solar energy. Background Art

[0002] It is well known to those skilled in the art that air source heat pumps are environmentally friendly and energy-saving heating equipment. Their heat comes from outdoor air, and there is no pollutant emission, which conforms to the ideal model of ecological heating. At present, the application of air source heat pumps in my country is becoming more and more widespread, playing an increasingly important role in major livelihood projects such as building energy conservation and replacing coal-fired heating. However, when the air source heat pump is operated in an outdoor low temperature and high humidity environment, the outdoor heat exchanger will frost, resulting in a decrease in its heating performance, and periodic defrosting is required to ensure the normal operation of the heat pump. The reliability and stability of defrosting is a key issue to ensure the efficient operation of air source heat pumps in various regions and various meteorological conditions.

[0003] From the practical application of air source heat pumps in recent years, the frosting and defrosting problems have not been well solved, especially under the harsh working conditions of medium and heavy frosting, the defrosting is often not clean, mainly manifested in that the outdoor heat exchanger often retains some defrosting water, and when heating again, a layer of ice that is difficult to melt will form at the bottom of the outdoor heat exchanger, increasing the heat transfer resistance of the outdoor heat exchanger, which has a serious impact on the heating quality of the air source heat pump. At present, the frosting and defrosting of air source heat sources has become a hot topic in the industry.

[0004] Air source heat pumps can be divided into two categories based on their capacity. One is large and medium-sized air source heat pump hot water units; the other is small split air source heat pumps. Small air source heat pumps have been widely used in recent years because of their convenient and flexible installation and low cost. Because the indoor heat exchanger of a small air source heat pump acts as an air-cooled condenser when providing heat, it can only produce heat by directly exchanging heat with the air in the heating environment. The evaporation characteristics of the heat exchanger when it serves as an evaporation device during defrosting have a more direct and rapid impact on the heating environment. In the actual operation of a small split air source heat pump (heating capacity below 5kW), "cold air" is often blown out at the end of defrosting, affecting the thermal comfort of the indoor environment.

[0005] In response to the restrictive technical problems currently encountered, as technical personnel in this field, the technical problem that urgently needs to be solved is: how to design an air source heat pump heat storage and defrosting device that can realize the effect and influence on the split air source heat pump and overcome the drawbacks of the existing technology.

[0042] like Figure 2 As shown, the energy storage body 31 disclosed in the present invention is a well-shaped energy storage device with a sealed structure. The well-shaped energy storage device is circular or polygonal in shape. The well-shaped energy storage device includes a protective body, a heat storage body 3106, and an energy conversion tube.

The purpose of the above structure is to make the well-shaped energy storage device have better heat insulation and high temperature resistance.

[0044] The heat storage body 3106 is located inside the enclosure. Figure 5 As shown, the heat storage body 3106 includes a heat storage enclosure 501 and a heat storage cavity 502. The heat storage cavity 502 is filled with heat storage material. The heat storage enclosure 501 is made of metal or ceramic and has a circular or polygonal shape. The heat storage material is a coupling of organic and inorganic.

[0045] The heat collection air inlet 23 and the heat collection source energy storage outlet 36 are connected through a transmission pipeline to transmit energy. The transmission pipeline is a galvanized air duct with a circular or rectangular shape. The outside of the transmission pipeline is coated with an insulation structure, and the insulation material is rock wool, glass fiber or polyurethane.

[0046] The first temperature detector 3108 is arranged inside the energy storage body 31 and is a thermal resistance sensor with a temperature measurement range of 0 to 200°C.

[0047] A second temperature control detector 2104 is arranged inside the upper flow channel of the collector 21 and is a thermocouple sensor with a temperature measurement range of 0 to 1000°C.

[0048] The energy storage defrost module 3 switches between the energy storage mode and the defrost mode through the first reversing valve 32 and the second reversing valve 34 , and the heat transfer medium is ethylene glycol or propylene glycol.

[0049] The collector 21 is located on the side or top of the air source heat pump module 1. The internal structure of the collector 21 includes a flow guide 2103, a lower flow channel 2101 as an air inlet side flow channel, and 2102 as a return air side flow channel; the flow guide 2103 is an arc-shaped fluid structure, and its material is aluminum alloy or copper alloy; the upper flow channel 2102 and the lower flow channel 2101 are cylindrical in shape, and flow guide holes are evenly distributed on one side of the outer arc surface of the flow channel.

[0050] Based on the above basic structure, the operating principle of the present invention is as follows:

[0051] Example 1: Heat collection and energy storage and auxiliary defrosting process

[0052] like Figure 1 As shown, when the temperature in the second temperature detector 2104 in the heat collection module 2 reaches the set value, the first air valve 25 is opened and the second air valve 25 is closed, and the power transmission device 22 and the transmission pipeline are used to transmit the heat collected by the collector 21 to the energy storage body 31, and the heat storage body 3106 in the energy storage body 31 collects and stores the heat to provide the defrosting heat demand of the air source heat pump module 1; when the temperature in the first temperature detector 3108 reaches the set value and remains unchanged for two hours, the first air valve 25 is closed and the second air valve 26 is opened, and the power transmission device 22 and the transmission pipeline are used to transmit the heat collected by the heat collection module 2 to the auxiliary defrost port 15, so as to increase the ambient temperature when the evaporation device 11 is in operation, thereby improving the working efficiency of the heat pump system; when the temperature in the second temperature detector 2104 in the heat collection module 2 is lower than the set value, the first air valve 25 is closed, the second air valve 26 is closed, and the power transmission device 22 stops running.

[0053] Further, such as Figure 3 As shown, under the action of the power transmission device 22, the transmission medium enters the lower flow channel 2101 and is evenly transmitted to the inside of the collector 21. Under the guidance of the flow guide 2103, the fluid flows evenly and is transmitted to the energy storage module 3 through the return air side flow channel 2101. The flow guide 2103 retards the movement speed of the fluid to a certain extent and changes the disordered flow in the direction of fluid transmission. This structure can improve the efficiency of energy absorption and conversion transmission of the collector module 2.

[0054] Furthermore, the heat storage body 3106 in the energy storage body 31 can be flexibly configured according to the use area, ambient temperature and defrosting heat requirements through the detachable upper movable top cover 3105.

[0055] Example 2: Energy storage and defrosting process of air source heat pump system

[0056] When the temperature in the second temperature detector 2104 in the thermal collection module 2 is lower than the set value and the temperature in the first temperature detector 3108 is lower than the set value, the first reversing valve 32 and the second reversing valve 34 switch to the energy storage mode of the air source heat pump system, and the energy storage defrosting power device 33 starts, and the heat transferred in the condensing device 14 is circulated through the energy storage outlet 3101 and the energy storage inlet 3102 and stored in the heat storage body 3106 in the energy storage body 31.

[0057] Furthermore, when the air source heat pump module 1 has a demand for defrosting heat, the first reversing valve 32 and the second reversing valve 34 are switched to the defrost mode. After a delay of 15 seconds, the energy storage defrost power device 33 is started, and is connected in parallel with the outside of the evaporator 11 through the energy storage defrost inlet 16 and the energy storage defrost outlet 17. The heat in the energy storage module 2 is used to melt the frost on the coil of the evaporator 11. At this time, the energy supply module 4 and the defrost cycle operate independently, and the source of defrost heat comes from the heat stored in the energy storage defrost module 3. The indoor heating cycle of the building and the outdoor defrost cycle of the air source heat pump module 1 do not interfere with each other, which ensures the stability of the indoor temperature of the building during defrosting, greatly improving the system operation stability and the comfort of building heating.

[0058] In another preferred embodiment of the present application, the air source heat pump heat storage defrosting device combined with solar energy also includes an air-assisted heating device (not shown in the figure), which is arranged inside the energy storage body 3-1. Under extreme weather conditions, the heat of the heat collection module 2 and the air source heat pump module 1 cannot meet the heat storage heat demand of the energy storage body 3-1. At the same time, the heat demand of the air source heat pump module 1 during the defrosting stage is too high, and the heat storage body 3-106 inside the energy storage body 3-1 is insufficient. At this time, the air-assisted heating device is started to provide the heat storage heat demand of the energy storage body 3-1 and the defrosting heat demand of the air source heat pump module 1, ensuring the stable and continuous supply of defrosting heat under extreme weather conditions and the operating stability of the energy supply module 4.

[0059] The above description is only a preferred embodiment of the invention and is not intended to limit the invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the invention should be included in the protection scope of the invention.
