Description

Technical Field

[0001] This utility model relates to the field of heating equipment, and in particular to a heating device and a heating system. Background Technology

[0002] With increasing global concern about climate change, many countries and regions are promoting reductions in fossil fuel use. Electric heating systems, especially those combined with renewable energy sources such as wind and solar power, can significantly reduce carbon emissions. Furthermore, as environmental awareness grows, more and more consumers are opting for heating methods with less environmental impact.

[0003] An air source heat pump is a highly efficient and environmentally friendly heating and cooling system. It provides heating by extracting heat from outdoor air and transferring it indoors, and vice versa, providing cooling in the summer.

[0004] Most indoor heating systems require ductwork for heat exchange with the outdoors. Conventional heating systems are typically designed with specific airflow directions in mind. For systems with high aesthetic requirements, installing conventional systems can present the following problems:

[0005] 1. Mismatch between product installation location and product air inlet / outlet location: Traditional products generally specify the location of the air inlet / outlet, such as at the top of the unit, where the unit draws in and exhausts air from the top. However, the user's installation location may not match the product. In this case, due to the internal structure, air can only be drawn in from the left and exhausted from the right. Such an installation method requires drilling holes from the top to install ductwork outdoors. At the same time, the ductwork cannot be hidden, affecting the indoor aesthetics. Therefore, the product installation will affect the indoor aesthetics.

[0006] 2. Affects normal product maintenance: Improper product installation will affect the daily maintenance and repair of the equipment, and it will be difficult to solve problems in a timely manner when they occur;

[0007] 3. Affects the insulation effect of the house: Using conventional heating equipment may require the removal of multiple or larger areas of walls to achieve the purpose of compatibility with the product. This will lead to a decrease in the insulation effect of the house, increase heat loss, affect the performance of the product, and worsen the user experience. Utility Model Content

[0037] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0038] In this utility model, when directions (up, down, left, right, front, and back) are described, it is only for the convenience of describing the technical solution of this utility model, and does not indicate or imply that the technical features referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0039] In this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," "exceeding," etc. are understood to exclude the stated number; "above," "below," "within," etc. are understood to include the stated number. In the description of this utility model, if "first" or "second" is used, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of indicated technical features or the order of the indicated technical features.

[0040] In this utility model, unless otherwise explicitly defined, terms such as "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a direct connection or an indirect connection through an intermediate medium; a fixed connection, a detachable connection, or an integrally formed connection; a mechanical connection, an electrical connection, or a connection capable of mutual communication; or the internal connection of two components or the interaction between two components. Those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model based on the specific content of the technical solution.

[0041] in, Figure 1 The reference direction coordinate system of this utility model embodiment is given below, in conjunction with Figure 1 The embodiments of this utility model will be described in the directions shown.

[0042] See Figure 1 This utility model provides a heating device, including a body 100, a fan 200, and a heat pump unit. The body 100 has an air inlet chamber 101 and an air outlet chamber 102 inside. Multiple preset air inlets 103, communicating with the air inlet chamber 101, are located on different sides of the body 100 and are embedded in the body 100. These preset air inlets 103 are flexibly selected during installation, and can be used as an air inlet as needed. Similarly, multiple preset air outlets 104, communicating with the air outlet chamber 102, are located on different sides of the body 100 and are embedded in the body 100. These preset air outlets 104 are flexibly selected during installation, and can be used as an air outlet as needed. The body 100 has an airflow channel between the air inlet cavity 101 and the air outlet cavity 102. The heat pump unit includes a first heat exchanger 400 disposed in the airflow channel and a fan 200 disposed in the body 100. The fan 200 is used to generate airflow that flows sequentially through a preset air inlet 103, air inlet cavity 101, first heat exchanger 400, air outlet cavity 102 and preset air outlet 104. During this process, the airflow exchanges heat with the first heat exchanger 400 of the heat pump unit.

[0043] The embodiments of this utility model can be used for heating and cooling. For example, when used for heating, the heat pump unit operates, the first heat exchanger 400 acts as an evaporator, and the fan 200 generates airflow that flows through the air inlet, air inlet cavity 101, first heat exchanger 400, air outlet cavity 102, and air outlet. The first heat exchanger 400 exchanges heat with the airflow, and the heat pump unit absorbs heat from the airflow through the first heat exchanger 400 and further transfers the heat to the water pipe system of the heating system to achieve the heating function. When used for cooling, the first heat exchanger 400 acts as a condenser, and the fan 200 generates airflow that flows through the air inlet, air inlet cavity 101, first heat exchanger 400, air outlet cavity 102, and air outlet. The first heat exchanger 400 exchanges heat with the airflow, and the heat pump unit continuously transfers heat from the water pipe system of the heating system to the first heat exchanger 400, and further cools the heat through the airflow via the first heat exchanger 400 to achieve the cooling function.

[0044] Combination Figures 1-13 In the technical solution of this utility model, multiple preset air inlets 103 communicating with the air inlet cavity 101 are provided on the side wall surfaces of the body 100 in different orientations. During use, a preset air inlet 103 in a specific direction can be selected according to the specific arrangement requirements during installation. At the same time, multiple preset air outlets 104 communicating with the air outlet cavity 102 are provided on the side wall surfaces of the body 100 in different orientations. During use, a preset air outlet 104 in a specific direction can be selected according to the specific arrangement requirements during installation.

[0045] This utility model provides a more convenient and flexible installation method. Users can choose the placement direction of the product according to their actual application scenario. Since the product can be installed in a variety of layouts, it is more practical and can be more widely used in actual scenarios such as apartments and old house renovations. In addition, this special design can perfectly fit the wall and hide the air duct connected to the outside after installation, making the interior more beautiful.

[0046] In some embodiments, see Figures 1-10 The preset air inlet 103 and preset air outlet 104 are equipped with removable covers 105, which are used to close the unused preset air inlet 103 and preset air outlet 104. The removable connection method, such as screws and clips, allows for easy selection of any preset air inlet 103 or preset air outlet 104, while the unused preset air inlet 103 and preset air outlet 104 are closed by the covers 105.

[0047] In some embodiments, see Figure 1The body 100 has an internal cavity arranged along the height direction. The air inlet cavity 101 is located at the bottom of the internal cavity, and the air outlet cavity 102 is located at the top of the internal cavity. The airflow generated by the fan 200 flows in from the bottom of the body 100 and flows out from the top of the body 100. During this process, it can more fully exchange heat with the first heat exchanger 400, thereby improving the heat exchange efficiency.

[0048] In some embodiments, see Figure 1 The internal cavity of the unit has a unit chamber between the air inlet chamber 101 and the air outlet chamber 102. The unit chamber is divided into a first unit chamber 107 and a second unit chamber by a partition. The first unit chamber 107 is located on the back side of the second unit chamber and forms an airflow channel connecting the air inlet chamber 101 and the air outlet chamber 102. Airflow can flow from the air inlet chamber 101 to the air outlet chamber 102 through the first unit chamber 107. The heat pump unit also includes a compressor and a second heat exchanger, which are disposed in the second unit chamber. This embodiment optimizes the internal structure of the heating equipment, making the entire structure more compact, achieving optimal structure and function, and reducing the overall volume of the heating equipment.

[0049] In some embodiments, see Figure 1 , Figure 11 The first heat exchanger 400 includes at least two heat exchanger units, with two adjacent heat exchanger units arranged in a V-shape in the first unit cavity 107. This design uses a V-shaped structure for the first heat exchanger 400, allowing air to enter from both sides of the V-shape and exit from the top, greatly improving heat exchange efficiency.

[0050] It is understandable that the first heat exchanger 400 can also adopt a single-piece structure, which is inclined or horizontally arranged in the first unit cavity 107.

[0051] In some embodiments, see Figures 1-10 The body 100 is provided with a front panel 108, a rear wall panel 109, a left side panel 110, and a right side panel 111. The front panel 108, rear wall panel 109, left side panel 110, and right side panel 111 can be integrated or assembled as one piece. The body 100 defines the internal cavity of the body through the front panel 108, rear wall panel 109, left side panel 110, and right side panel 111. The rear wall panel 109 of the body 100 is provided with a rear preset air inlet 103 and a rear preset air outlet 104. The rear preset air inlet 103 is located below the rear preset air outlet 104. The left side panel 110 of the body 100 is provided with a left preset air inlet and a left preset air outlet. The left preset air inlet is located below the left preset air outlet. The right side panel 111 of the body 100 is provided with a right preset air inlet and a right preset air outlet. The right preset air inlet is located below the right preset air outlet. In this embodiment, the body 100 is provided with three preset air inlets 103 and three preset air outlets 104 on the left, rear, and right sides, respectively. In actual use, this can form a configuration as follows: Figures 2-10The nine installation methods shown allow for nine different layouts, making them more practical and applicable to a wider range of scenarios such as apartments and old house renovations.

[0052] In some embodiments, see Figure 1 The fan 200 is located in the air outlet cavity 102. The fan 200 can be an axial flow fan or a centrifugal fan, etc. The fan 200 generates negative pressure in the air outlet cavity 102, thereby generating airflow that flows sequentially through the preset air inlet 103, the air inlet cavity 101, the first heat exchanger 400, the air outlet cavity 102, and the preset air outlet 104. By placing the fan 200 in the air outlet cavity 102 instead of the air inlet cavity 101, the normal operation of the fan 200 is also avoided due to water droplets generated during the operation of the first heat exchanger 400.

[0053] Furthermore, in some embodiments, see Figure 1 The fan 200 includes a centrifugal fan that can generate airflow that is drawn in from the bottom and discharged from the side. The centrifugal fan has a higher air pressure, which improves the heat exchange efficiency of the first heat exchanger 400.

[0054] In some embodiments, see Figures 1-10 The heating equipment also includes an air vent connector 112, which can be detachably installed on the preset air inlet 103 and preset air outlet 104. The air vent connector 112 extends outward from the body. In use, the air vent connector 112 can be assembled to the selected preset air inlet 103 and preset air outlet 104 as needed to realize air intake and air exhaust.

[0055] See Figure 12 , Figure 13 The embodiments of this utility model primarily focus on the product application market, targeting apartments or old house renovation markets. For single-family homes or villas, heating equipment can be installed independently within 600mm of the wall to replace boilers or other non-clean energy heating equipment. For apartment buildings, the limitation of outdoor installation due to limited public space can be ignored, and the equipment can be installed indoors, placed within 500mm of a washbasin or other locations. The concealed installation saves indoor space while maintaining aesthetics, and does not affect the normal use and maintenance of the product. Especially for foreign markets such as Europe, the use of clean energy offers higher economic benefits as well as better safety and reliability.

[0056] An embodiment of this utility model also provides a heating system, including the heating equipment in any of the above embodiments.
