Description

Technical Field

[0001] This utility model relates to the field of heat pump technology, and in particular to a heat pump heating water supply device. Background Technology

[0002] With the continuous growth of energy demand and the increasing awareness of environmental protection, efficient and energy-saving hot water supply technology has become a hot topic in research and application. Traditional hot water supply devices mostly use electric heating, coal or gas heating, which have problems such as high energy consumption, high operating costs and serious environmental pollution. Heat pump technology, as a highly efficient and energy-saving heating method, heats water by absorbing heat from the environment. Compared with traditional heating methods, it can significantly reduce energy consumption and has significant energy-saving advantages and environmental benefits. Therefore, it has been widely used in the field of hot water supply. Utility Model Content

[0003] The purpose of this invention is to address the many shortcomings of existing heat pump water heating devices. For example, the overall structure design of the device is not reasonable enough, the components are scattered, resulting in a large installation space occupation and making it difficult to centrally manage and maintain the equipment; the heating efficiency of some heat pump units is low, making it difficult to meet the demand for large-scale, high-intensity hot water supply; and the insulation performance of the water storage tank is poor, causing serious heat loss during the storage of hot water and resulting in energy waste.

[0004] This utility model achieves the above objectives through the following technical solutions: A heat pump water heating and supply device includes a rectangular water storage tank containing water to be heated. A repair and maintenance inlet is located at one upper corner of the tank. A heat pump unit is mounted on one side of the tank, with a support base fixedly connected to its bottom. A delivery pipe is located on one upper side of the tank. An insulation layer surrounds the outside of the tank. The heat pump unit includes at least three heat pump compressors and matching heat exchange piping, connected to the water storage tank via the piping for heating the water inside. One end of the delivery pipe is connected to... The top of the water storage tank extends to the external water supply end of the device, used to transport heated water to the point of use. By clearly defining the integrated structure of the water storage tank, inspection and repair inlet, heat pump unit, support base, delivery pipeline, and insulation layer, a complete heat pump heating water supply system is constructed. The rectangular water storage tank is suitable for conventional installation space, and the inspection and repair inlet optimizes the convenience of operation and maintenance. The heat pump unit integrates multiple compressors and heat exchange pipelines to ensure heating efficiency and capacity. The insulation layer reduces heat loss, and the delivery pipeline is precisely connected to the internal and external water circuits to achieve stable and efficient heating water supply function. The overall architecture ensures that the device is practical and reliable.

[0005] Furthermore, the heat pump unit includes a heat pump, with flanged splicing pipes connected to both ends of the bottom of the heat pump. A flow regulating valve is installed on the flanged splicing pipe, and a pipe is connected to one side of the flanged splicing pipe. This refines the components and connection methods of the heat pump unit. The flanged splicing pipe facilitates quick disassembly and maintenance of the pipeline, and the flow regulating valve can flexibly adjust the water flow to adapt to different water usage scenarios (such as flow adaptation for peak and off-peak water usage). The modular design makes the installation and maintenance of the heat pump unit more convenient, and can optimize energy consumption and water supply stability through flow regulation, improving the adaptability and operation and maintenance efficiency of the device.

[0006] Furthermore, the insulation layer is made of polyurethane foam with a thickness of 5-10mm, which is used to reduce the heat loss of hot water in the water storage tank.

[0007] Furthermore, the heat exchange pipeline of the heat pump unit is connected to the interface on the bottom side of the water storage tank via a flange, and the three heat pump compressors are arranged in a straight line at equal intervals on the support base, with the distance between adjacent compressors being 15-25cm, which facilitates pipeline connection and equipment maintenance.

[0008] Furthermore, the conveying pipeline is made of stainless steel, and the outer surface of the pipeline is coated with an anti-corrosion coating.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. This device significantly improves heating efficiency by integrating at least three heat pump compressors and matching heat exchange pipelines, enabling it to quickly meet the demand for large-scale hot water supply. At the same time, the water storage tank is wrapped with a 5-10mm thick polyurethane foam insulation layer, which effectively reduces heat loss during hot water storage and lowers energy consumption. While ensuring a stable hot water supply, it greatly improves the energy-saving effect of the device, which is in line with the trend of energy conservation and environmental protection.

[0010] 2. The rectangular water tank design is suitable for conventional installation spaces, and a repair and maintenance inlet is provided at the top for easy daily maintenance and water replenishment. The heat pump unit uses flanged splicing pipes for connecting pipelines and is equipped with a flow regulating valve for easy and quick disassembly and maintenance, and can flexibly control the water flow. In addition, the three heat pump compressors are arranged in a straight line at equal intervals on the support base, which further optimizes the pipeline connection and equipment maintenance process, reduces maintenance difficulty and cost, and improves operation and maintenance efficiency.

[0011] 3. The conveying pipeline is made of stainless steel and has an anti-corrosion coating, which enhances the corrosion resistance and service life of the pipeline and ensures the stability of the hot water delivery process; the flow regulating valve can flexibly adjust the water flow according to different scenarios such as peak and off-peak water usage. Combined with the efficient heating of the heat pump unit and the stable heat storage of the water tank, precise water supply is achieved, making the device widely applicable to various water usage scenarios and greatly improving the applicability and water supply stability of the device.
