Description

Technical Field

[0001] This utility model belongs to the field of heating technology and relates to an air heat source pump heating device. Background Technology

[0002] An air source heat pump is an energy regeneration device that uses air heat energy for heating. It absorbs a large amount of low-temperature heat energy from the air with very little electricity and converts it into high-temperature heat energy through compression by a compressor. It is widely used in the energy storage, heating and heating industries.

[0003] CN209840251U discloses an intelligent air source heat pump heating and hot water supply system, including an air source heat pump and a distribution tank. The air source heat pump is equipped with heat exchange tubes inside. A main water supply pipe is provided on one side of the air source heat pump. One end of the main water supply pipe is installed on the surface of the working water tank. The air source heat pump and the working water tank are connected through the main water supply pipe. A pressure gauge is provided on one side of the working water tank. The pressure gauge is installed on the surface of the cold water pipe. A cold water replenishment tank is provided at one end of the cold water pipe, so that the heat from the underfloor heating radiant pipe can be fully supplied to the floor for heating through the heat dissipation metal mesh.

[0004] CN208595591U discloses an air source heat pump-assisted solar heating and domestic hot water supply device. When the solar collector cannot reach the heating temperature, the air source heat pump serves as an auxiliary supplement to the heating supply, ensuring that the heating and hot water temperature requirements are met.

[0005] Because the heating capacity and efficiency of air source heat pumps gradually decrease as the outdoor ambient temperature drops, resulting in poor stability, they are usually coupled with other forms of heat sources (such as solar energy, water source heat pumps, and underfloor heating pumps) to meet heating needs in extreme weather conditions. As ambient temperatures decrease, building heat loads continuously increase, but existing heating systems cannot flexibly adjust their temperature according to actual needs, still suffering from poor stability, low heating efficiency, and high operating costs. Therefore, a new air source heat pump heating system needs to be designed to address these issues. Utility Model Content

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0031] It should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] In one specific embodiment, this utility model provides an air source heat pump heating device, including an air source heat pump unit, a water source heat pump body, a heat storage device, and a heating terminal. The heat storage device includes a high-temperature heat storage tank, a low-temperature heat storage tank, and a mixed heat storage tank, used to store heat energy at different temperatures respectively. The high-temperature heat storage tank contains high-grade heat energy at the highest temperature, the low-temperature heat storage tank contains low-grade heat energy at the lowest temperature, and the mixed heat storage tank contains heat energy at an intermediate temperature. The mixed heat storage tank is connected to the high-temperature heat storage tank, the low-temperature heat storage tank, and the heating terminal. The high-grade heat energy in the high-temperature heat storage tank and the low-grade heat energy in the low-temperature heat storage tank can enter the mixed heat storage tank and mix, so that the heat energy temperature is in the intermediate range that meets the heating temperature requirements. The mixed heat storage tank can directly supply heat to the heating terminal. The high-temperature heat storage tank is also connected to the main body of the water source heat pump and the heating terminal. The heat energy of the main body of the water source heat pump enters the high-temperature heat storage tank for storage, and the high-temperature heat storage tank can directly use the stored heat to provide high-grade heat energy to the heating terminal. The low-temperature heat storage tank is connected to the air source heat pump group and the heating terminal. The heat energy of the air source heat pump group enters the low-temperature heat storage tank for storage, and the low-temperature heat storage tank can directly use the stored heat to provide low-grade heat energy to the heating terminal. The air source heat pump group is also connected to the main body of the water source heat pump and the heating terminal, so that the low-grade heat energy in the air source heat pump group enters the main body of the water source heat pump for further heating and storage or direct heating. The heating terminal is also circulated to the main body of the water source heat pump, and the water outlet of the heating terminal flows back to the air source heat pump group and the main body of the water source heat pump, respectively, to realize heat energy circulation.

[0034] In some embodiments, the air source heat pump unit includes at least two air source heat pumps connected in series, such that the temperature of the heat energy flowing through multiple air source heat pumps increases progressively, reducing the adverse effects of extreme external air on heat energy transfer. Those skilled in the art can adjust the number of air source heat pumps to 2, 3, 4, 5, or other numbers according to actual process conditions to ensure heating needs are met. Furthermore, the outlet end of the air source heat pump unit is equipped with an outlet temperature detection component for real-time monitoring of the outlet temperature, allowing operators to select low-grade heat energy storage or heat energy heating based on the outlet heat energy temperature of the air source heat pump unit. When storing low-grade heat energy, the outlet heat energy of the air source heat pump unit is directly input into the heat storage device; when heating, the outlet heat energy of the air source heat pump unit is passed into the main body of a water source heat pump for reheating.

[0035] Specifically, the outlet of the air source heat pump unit is connected to the water source heat pump body and the low-temperature heat storage tank via a first pipe and a second pipe, respectively. When the heat energy temperature of the air source heat pump unit cannot reach the set temperature, the outlet heat energy of the air source heat pump unit is introduced into the water source heat pump body through the first pipe for further heating. When the heat energy temperature of the air source heat pump unit reaches the set temperature for low-grade heat energy, the outlet heat energy of the air source heat pump unit can be directly input into the low-temperature heat storage tank for storage through the second pipe according to the actual heating demand, and heating can be provided according to the heating load.

[0036] The outlet end of the water source heat pump body is connected to the high-temperature heat storage tank and the inlet end of the heating terminal via a third pipe and a fourth pipe, respectively. The high-grade heat energy from the water source heat pump body is input into the high-temperature heat storage tank for storage via the third pipe, or it can be directly supplied to the heating terminal via the fourth pipe. Those skilled in the art can, according to actual needs, turn on the water source heat pump body to directly supply heat to the heating terminal during peak heating periods, or simultaneously turn on the high-temperature heat storage tank and the water source heat pump body for joint heating; during off-peak heating periods, a portion of the high-grade heat energy from the water source heat pump body can be stored.

[0037] This utility model does not specifically limit the structure of the main body of the water source heat pump. Its essential components include the condenser, evaporator, expansion valve, compressor, necessary pipelines, conventional valves and general pump equipment, etc., which are necessary to realize the complete process. Those skilled in the art can add layouts based on the process flow and equipment structure selection. This utility model does not make any special requirements or specific limitations in this regard.

[0038] The outlet of the heating terminal is connected to the inlet of the air source heat pump unit and the inlet of the water source heat pump body via a first return pipe and a second return pipe, respectively. Furthermore, a filter is installed at the outlet of the heating terminal, so that the water from the heating terminal is filtered and purified before flowing back to the air source heat pump unit or the water source heat pump body.

[0039] Each of the first, second, third, and fourth pipes, as well as the first and second return pipes, is independently equipped with a control valve to control the flow and shut-off of different pipes. The control valve can be a manual valve, a solenoid valve, or an electric valve; this invention does not specifically limit the type. Furthermore, the first, second, third, and fourth pipes, as well as the first and second return pipes, are also equipped with drive pumps necessary for ensuring the integrity of the process.

[0040] Furthermore, the low-temperature heat storage tank is connected to the inlet of the water source heat pump body via a water replenishment pipe. Since the water source heat pump body stores some heat energy in the form of hot water in the high-temperature heat storage tank during operation according to heating demand, the water volume in the water source heat pump body decreases. Therefore, this invention utilizes the low-grade hot water in the low-temperature heat storage tank to replenish the water source heat pump body, preventing hot water from causing malfunction, reducing temperature difference and energy consumption, and improving operating efficiency.

[0041] In some embodiments, the high-temperature heat storage tank and the low-temperature heat storage tank are connected to the mixed heat storage tank via a first mixing branch pipe and a second mixing branch pipe, respectively. Each of the first and second mixing branch pipes is independently equipped with an electric butterfly valve and a mixing drive pump. The outlets of the high-temperature heat storage tank, the low-temperature heat storage tank, and the mixed heat storage tank are respectively equipped with a first heating branch pipe, a second heating branch pipe, and a third heating branch pipe. The outlets of the first, second, and third heating branch pipes are independently connected to a heating pipeline, which is connected to the inlet of the heating terminal. Each of the first, second, and third heating branch pipes is independently equipped with a regulating valve. By opening or closing different regulating valves, the supply of heat energy from the high-temperature heat storage tank, the low-temperature heat storage tank, or the mixed heat storage tank to the heating terminal can be switched.

[0042] Furthermore, the high-temperature heat storage tank is equipped with a first temperature detection component and a first liquid level detection component for real-time monitoring of the temperature and liquid level within the high-temperature heat storage tank. The low-temperature heat storage tank is equipped with a second temperature detection component and a second liquid level detection component for real-time monitoring of the temperature and liquid level within the low-temperature heat storage tank. The mixed heat storage tank is equipped with a third temperature detection component and a third liquid level detection component for real-time monitoring of the temperature and liquid level within the mixed heat storage tank.

[0043] A first insulation layer is provided between the high-temperature heat storage tank and the mixed heat storage tank, and a second insulation layer is provided between the mixed heat storage tank and the low-temperature heat storage tank. Furthermore, the outer walls of the high-temperature heat storage tank, the low-temperature heat storage tank, and the mixed heat storage tank are independently provided with insulation layers to reduce heat transfer loss. This invention does not specifically limit the materials of the first insulation layer, the second insulation layer, and the insulation layers; any commonly used insulation material in the art can be used.

[0044] It should be noted that the air source heat pump unit and the water source heat pump body described in this utility model are also provided with necessary connecting pipes and switch control valves. This utility model does not make any special limitations on these. Those skilled in the art should reasonably adjust, add or delete them according to actual production needs. It should be clarified that new technical solutions generated by deleting some unnecessary connecting pipes and switch control valves, or replacing single-function switch control valves with multi-function integrated control valves, or using external automatic control systems electrically connected to the switch control valves to control the opening of the corresponding valves, etc., which are common and well-known technical means by those skilled in the art, also fall within the scope of disclosure and protection of this utility model.
