Description

Technical Field

[0001] This utility model relates to the field of electric auxiliary heating technology, and more specifically, to an air source heat pump heating control device with adaptive adjustment function. Background Technology

[0002] An air source heat pump is a device that uses heat energy from the air to heat water. Its working principle involves a refrigerant absorbing heat from the air and then transferring that heat to the water. Air source heat pumps offer advantages such as high energy efficiency, environmental friendliness, and energy saving, and are widely used in residential, commercial, and industrial applications. However, under certain extreme climatic conditions (such as cold weather), the performance of air source heat pumps may be affected, leading to reduced heating efficiency and failure to meet users' hot water needs.

[0003] To address this issue, an electric auxiliary heating device has been introduced into the air source heat pump system. The role of the electric instantaneous auxiliary heater is to provide additional heating capacity when the air source heat pump cannot operate effectively, ensuring a continuous and stable supply of hot water. This combined system not only improves the overall reliability and stability of the system but also ensures a sufficient supply of hot water even under special conditions. However, existing air source heat pump electric auxiliary heating systems still have some shortcomings in design and function, requiring further optimization and improvement.

[0004] First, existing systems still have room for improvement in heating efficiency and energy utilization. How to better combine the advantages of air source heat pumps and electric instantaneous auxiliary heaters to maximize heating efficiency and reduce energy consumption is a pressing issue. Second, the system's automated control and monitoring methods are not yet perfect. How to use intelligent control methods to monitor and adjust the system's operating status in real time to ensure it operates at its optimal condition is also an important research direction. Furthermore, existing systems need further strengthening in terms of safety monitoring measures to prevent malfunctions or hazards under extreme conditions. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide an air source heat pump heating control device with adaptive adjustment function. It can achieve comprehensive automated monitoring and control. Through the first circulation pump and the second circulation pump, it realizes the circulation heating and reflux of hot water, ensuring the stability and uniformity of water temperature, improving user experience, and reducing energy consumption and carbon emissions through energy efficiency optimization design, thus contributing to the achievement of environmental protection goals.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] An air source heat pump heating control device with adaptive adjustment function includes a thermal storage and hot water supply tank and an air source heat pump. A cold water supply pipe is installed on the upper right side of the thermal storage and hot water supply tank, and a hot water supply pipe is located directly below the cold water supply pipe. A hot water circulation system component is located on the right side of the thermal storage and hot water supply tank. An instantaneous electric auxiliary heater and a fluid monitoring and power device are respectively installed at both ends of the left side of the thermal storage and hot water supply tank. An air source heat pump is connected to one side of the instantaneous electric auxiliary heater and the fluid monitoring and power device. Water in the thermal storage and hot water supply tank enters through the cold water supply pipe, is heated by the air source heat pump and the electric auxiliary heater, and then flows out through the hot water supply pipe.

[0010] Furthermore, the hot water circulation system components include a first solenoid valve, a first temperature sensor, a first pressure gauge, a first circulation pump, and a hot water return pipe. The first circulation pump returns hot water from the hot water supply pipe to the heat storage hot water tank through the hot water return pipe, and the first temperature sensor (7) located at the end of the return pipe (10) controls the start and stop of the circulation pump.

[0011] Based on the above characteristics, the fluid monitoring and power equipment includes a second circulation pump, a second pressure gauge, and a third temperature sensor. The second circulation pump is responsible for pressurizing the hot water in the hot water storage tank to heat and circulate it through the air source heat pump device. The third temperature sensor controls the start and stop of the solenoid valve before the auxiliary heat source. When heating with the auxiliary heat source is required, the solenoid valve before the auxiliary heat source is opened and the solenoid valve of the bypass pipe is closed, so that the water from the air source heat pump is heated to the standard by the auxiliary heat source and then enters the water tank. When heating with the auxiliary heat source is not required (the water temperature of the air source heat pump is up to standard), the solenoid valve before the auxiliary heat source is closed and the solenoid valve of the bypass pipe is opened, so that the hot water from the air source heat pump that meets the standard directly enters the hot water storage tank.

[0012] In some embodiments, a control box is installed in front of the thermal storage and hot water supply tank. A liquid level sensor and a second temperature sensor are respectively installed on the left side of the thermal storage and hot water supply tank, offset from the position of the instantaneous electric auxiliary heater and the fluid monitoring and power equipment. The liquid level sensor is used to monitor the change of water level in the thermal storage and hot water supply tank. A second solenoid valve is installed on the instantaneous electric auxiliary heater to control the working state of the instantaneous electric auxiliary heater.

[0013] According to the above features, the air source heat pump is provided with an inlet pipe and an outlet pipe on the lower right side. The bottom of the air source heat pump is equipped with a base. The inlet pipe is used to introduce hot or cold water into the air source heat pump, and the outlet pipe is used to transport the heated hot water to the hot water storage tank.

[0014] 3. Beneficial effects

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] 1) This utility model effectively ensures reliable heating of the hot water system under extreme temperatures through an instantaneous electric auxiliary heater, greatly improving heating efficiency and shortening waiting time. This system combines the advantages of an air source heat pump and electric auxiliary heating, allowing for flexible switching under different operating conditions, maximizing energy savings and reducing operating costs.

[0017] 2) The system is equipped with various sensors and control devices, including level sensors, temperature sensors, pressure gauges, and solenoid valves, enabling comprehensive automated monitoring and control to ensure optimal system operation and minimize human intervention. The first and second circulation pumps facilitate the circulation, heating, and recirculation of hot water, ensuring temperature stability and uniformity and improving user experience.

[0018] 3) The system is designed with multiple safety monitoring measures, including water level monitoring, temperature monitoring, and pressure monitoring, to ensure safety under various operating conditions and prevent dangerous situations such as overheating and overpressure. The air source heat pump can introduce hot or cold water through the inlet pipe and deliver the hot water to the storage tank through the outlet pipe. It has strong adaptability and scalability and can be applied to different scenarios and needs.

[0019] 4) This utility model, through its modular system design, makes the inspection and replacement of each component more convenient, reducing maintenance costs and time. Through energy efficiency optimization design, it reduces energy consumption and carbon emissions, contributing to the achievement of environmental protection goals. Attached Figure Description
