Description

Technical Field

[0001] This utility model relates to the field of heating equipment technology, specifically a novel radiative heat dissipation and convection cooling composite terminal device. Background Technology

[0002] A dual-source heat pump system is an air-source heat pump system that integrates cooling and heating functions. It achieves both summer cooling and winter heating through a single main unit, and has advantages such as high efficiency, energy saving, and high comfort. It is widely used in residential and commercial buildings.

[0003] Currently, the heating and cooling terminals and pipelines in dual-source heating and cooling systems are two independent sets of devices, mainly including the heat source and cold source main unit, terminal equipment, distribution system, control system and other auxiliary components. The fan coil unit in the existing terminal equipment is mainly divided into left and right structures, and the water tank in the traditional distribution system occupies a large space, which leads to many limitations during installation. In addition, the system requires professional installation, which is highly professional and expensive, thus increasing the cost. Moreover, in actual installation, underfloor heating requires increasing the floor height, and horizontal installation of fan coil units will reduce the indoor ceiling height, so the room height is affected by the terminal equipment, reducing the comfort of people using the system.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a novel radiative heat dissipation and convection cooling composite terminal device, comprising a radiative unit and a convection unit. The convection unit consists of a housing and a surface cooler installed inside it. An air outlet is provided on the front of the housing, and an air inlet is provided on the side of the housing. A circulation pipeline is also provided inside the housing. A radiative unit is configured outside the housing. The radiative unit is installed on the outside of the housing, and the radiative unit is connected to the surface cooler through the circulation pipeline.

[0006] Optionally, the circulation pipeline is located inside the shell and connected to the surface cooler and the radiant unit. The first water inlet is provided at one end of the circulation pipeline located on the outer side of the bottom of the shell, and the first water outlet is provided at one end of the circulation pipeline located on the outer side of the top of the shell. A second valve is installed between the first water outlet and the connection part of the surface cooler. The second valve is controlled by the dual-supply control system.

[0007] Optionally, the housing has an overall vertical structure and multiple flow channels inside to ensure efficient operation of the convection heat dissipation / cooling unit.

[0008] Optionally, the radiant unit is a steel column radiator with a large enough water output to replace the traditional buffer tank, reducing the space occupied by the equipment while ensuring a sufficient and stable water volume when the unit is working. A second water inlet is set at the bottom of the left side of the radiant unit, which is connected to the circulation pipeline through the first valve. A second water outlet is set at the top of the left side of the radiant unit, which is connected to the first water outlet.

[0009] Optionally, the first valve is connected to the inlet of the second water inlet, and the first valve is controlled by the dual-supply control system.

[0010] Optionally, the surface cooler piping is equipped with an electric valve structure, which can supply on demand and save energy. At the same time, it ensures that no condensation occurs in the terminal devices when they are not in operation during summer when multiple terminal devices are running. The convection heat dissipation / cooling unit piping is also equipped with an electric valve structure, which can supply on demand and save energy. At the same time, it ensures that no condensation occurs in the terminal devices when they are not in operation during summer when multiple terminal devices are running.

[0011] Optionally, the circulation pipeline is divided into an inlet pipeline and an outlet pipeline. The inlet pipeline is connected to the first inlet and has three inflow interfaces with the surface cooler. The outlet pipeline has three outflow interfaces with the surface cooler. The inlet and outlet pipelines correspond one-to-one and are evenly distributed vertically on one side of the surface cooler. The outlet pipeline is connected to the second valve, which can improve the efficiency of water flow through the convection unit, thereby improving the heating and cooling efficiency of the convection unit.

[0012] This utility model provides a novel combined radiative heat dissipation and convective cooling terminal device, which has the following beneficial effects: 1. This novel radiative heat dissipation and convection cooling composite terminal device, through the cooperation of radiative heat dissipation and convection cooling units, can avoid the installation limitations caused by the left and right structure of the pipe opening of traditional fan coil units, improve the adaptability of the terminal device of the dual-supply system during installation and use, and can also achieve surface installation, avoiding the problem of occupying extra space on the ground and ceiling required by traditional concealed installation methods, improving the comfort of use, and reducing installation, later use and maintenance costs, providing convenience for users.

[0013] 2. This new type of radiant heat dissipation and convection cooling composite terminal device achieves heating through radiant heat dissipation of steel columns. It can replace the traditional buffer water tank while ensuring the unit's water consumption, reducing the space occupied by the unit and lowering the installation conditions of the unit.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figure 1 This utility model provides a technical solution: it consists of a convection unit and a radiation unit 5. The convection unit mainly consists of an outer shell 1 and an internally installed surface cooler 3. The top and bottom ports of the surface cooler 3 are connected to a circulation pipe 8. The inlet and outlet of the circulation pipe 8 are a first inlet 81 and a first outlet 82, respectively. The radiation unit 5 is arranged on the left side of the shell 1. The bottom and top of the radiation unit 5 are respectively provided with a second inlet 51 and a second outlet 52. A first valve 6 is connected to the left end of the bottom of the circulation pipe 8. The other end of the first valve 6 is connected to the second inlet 51, and the second outlet 52 is connected to the first outlet. 82 connects the two valves. At the same time, a second valve 7 is provided between the first water outlet 82 and the surface cooler 3. The other end of the second valve 7 is connected to the water outlet of the surface cooler 3 through the circulation pipe 8. When the device is working, the first valve 6 and the second valve 7 are opened at the same time. Water flows from the first water inlet 81 through the first valve 6 and the second water inlet 51 into the radiant unit 5, and then is discharged from the second water outlet 52 and the first water outlet 82, realizing the heating function of the radiant unit 5 and the surface cooler 3. When the first valve 6 is closed, the second valve 7 remains open, and water flows from the first water inlet 81 and then from the first water outlet 82, realizing the cooling function of the surface cooler 3.

[0018] Please see Figure 1The device has a vertical structure, and the radiant unit 5 is a steel column radiant heat dissipation structure, which realizes the main winter heating function. By setting the radiant unit 5 as a steel column radiant heat dissipation structure, its large water storage capacity can be used to replace the traditional buffer water tank, ensuring sufficient and stable water capacity when the unit is working, ensuring the normal operation of the unit, and greatly reducing the impact of the large space occupation of the traditional dual-supply system. At the same time, with the cooperation of the surface cooler 3, convection cooling is realized in summer, and the entire dual-supply system can be installed on the surface, avoiding the problem of occupying room floor and ceiling space required by the traditional structure, reducing space occupation, replacing the concealed structure of the traditional dual-supply system, eliminating the need for professional installers, and improving the installation efficiency of the system by 90% compared with the traditional fan coil system. It greatly reduces the labor costs of installation, use and subsequent maintenance, and can be used immediately after installation.

[0019] Please see Figure 2 The housing 1 has an air inlet 4 on its side and an air outlet 2 on its front, which ensures normal airflow during system operation. The vertical structure also enables multi-component flow channels, ensuring efficient operation of the convection heat dissipation / cooling unit. It also solves the installation limitation caused by the left and right structure of traditional fan coil units, allowing the radiative heat dissipation and convection cooling composite terminal device to be properly matched on both sides, improving the adaptability and practicality of the device.

[0020] Please see Figure 1 The cooling coil 3 has an electric valve structure installed in its piping, which can achieve on-demand supply and energy saving. At the same time, it can also ensure that when multiple terminal devices are running, there will be no condensation in the terminal devices when they are not in operation during the summer.

[0021] In summary, this novel radiant heat dissipation and convection cooling combined terminal device is used by installing it in the area of ​​use, connecting the power supply and other lines, and connecting the circulation pipe 8 to the corresponding water source. After being put into use, when the heating function is needed, the dual-supply system controls the opening of the first valve 6 and the second valve 7. Water flows from the first inlet 81 through the second inlet 51 and out through the second outlet 52, thus achieving simultaneous heating function of the radiant unit 5 and the convection heat dissipation unit. When cooling, the system closes the first valve 6, and water flows from the first inlet 81 and out through the first outlet 82. The convection cooling unit controls the surface cooler 3 to achieve the cooling function. If it is necessary to shut down the convection heat dissipation / cooling unit, simply close the second valve 7.
