Description

Technical Field

[0001] This utility model relates to the field of waste heat utilization technology of central air conditioning, and specifically to a waste heat utilization device for central air conditioning. Background Technology

[0002] Central air conditioning is a system that uses a main unit to drive multiple terminals through air ducts or chilled / hot water sources, thereby achieving unified regulation of air temperature, humidity, and cleanliness throughout a house or multiple rooms. It adopts a centralized cooling / heating method, which is highly efficient and energy-saving, and provides uniform and comfortable airflow. It can be perfectly concealed in the ceiling, saving space while maintaining the aesthetics of the interior. It is widely used in homes, commercial and industrial places.

[0003] During operation, the outdoor unit of a central air conditioning system discharges waste heat gas. The waste heat gas discharged by the outdoor unit is the sum of indoor heat and heat generated by the compressor. However, the waste heat gas is directly discharged into the air, resulting in heat loss and energy waste.

[0004] Therefore, a waste heat utilization device for central air conditioning is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a central air conditioning waste heat utilization device in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A central air conditioning waste heat recovery device includes a base plate, a support column on the top of the base plate, a fixed shell on the top of the support column, a waste heat recovery mechanism for recovering waste gas heat inside the fixed shell, and the waste heat recovery mechanism is located on the top of the base plate. Connecting pipes are provided on both sides of the fixed shell. An auxiliary mechanism for stirring and turbulence is provided on the waste heat recovery mechanism, and the auxiliary mechanism is located on the top of the base plate.

[0008] Furthermore, the waste heat recovery mechanism includes a fixed channel, which is fixedly installed inside the fixed shell and corresponds to the connecting pipe. A baffle is fixedly installed inside the fixed channel.

[0009] Furthermore, the number of baffles is set to four, which are arranged in pairs, alternating vertically.

[0010] Furthermore, heat dissipation fins are fixedly installed on the outer wall of the fixed channel, an oil pump is fixedly installed on the top of the base plate, a plate heat exchanger is fixedly installed on the top of the base plate, and the oil pump and the plate heat exchanger are connected by pipes. Both the oil pump and the plate heat exchanger are connected by pipes to the fixed shell.

[0011] Furthermore, the auxiliary mechanism includes a support base, which is fixedly installed inside the fixed channel. A T-shaped circular groove is formed on the surface of the support base, and a T-shaped shaft is rotatably installed on the inner wall of the T-shaped circular groove.

[0012] Furthermore, fan blades are fixedly mounted on the surface of the T-shaped shaft, and the fan blades are distributed in the center of the fixed channel.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model, through the setting of a waste heat recovery mechanism and auxiliary mechanisms, allows the waste heat gas generated by the central air conditioning system to enter the waste heat recovery mechanism through a connecting pipe during use. As the waste heat recovery mechanism absorbs, converts, and recovers the heat, it can be reused. Meanwhile, the waste heat gas generated by the central air conditioning system drives the auxiliary mechanism to disrupt the laminar flow state, increase the airflow turbulence, and make the heat more evenly distributed to the waste heat recovery mechanism, thereby improving the overall heat exchange efficiency. This enables the recovery and utilization of the heat energy of the waste heat gas generated by the central air conditioning system, saving energy consumption and demonstrating strong practicality.

[0023] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0024] In the description of the embodiments of this utility model, it should be noted that the terms "inner", "outer", "upper", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship that the utility model product is usually placed in during use.

Therefore, they should not be construed as limitations on this utility model.

[0025] like Figure 1-2 As shown, a central air conditioning waste heat recovery device includes a base plate 1, a support column 2 on the top of the base plate 1, a fixed shell 3 on the top of the support column 2, a waste heat recovery mechanism 5 for recovering waste gas heat inside the fixed shell 3, and the waste heat recovery mechanism 5 is located on the top of the base plate 1. Connecting pipes 4 are provided on both sides of the fixed shell 3. Figure 1-3 As shown, specifically, the waste heat recovery mechanism 5 includes a fixed channel 501, which is fixedly installed inside the fixed shell 3 and corresponds to the connecting pipe 4. A baffle 502 is fixedly installed inside the fixed channel 501, and the number of baffles 502 is set to four, which are arranged in pairs, one above the other. Heat dissipation fins 503 are fixedly installed on the outer wall of the fixed channel 501. An oil pump 504 is fixedly installed on the top of the base plate 1, and a plate heat exchanger 505 is fixedly installed on the top of the base plate 1. The oil pump 504 and the plate heat exchanger 505 are connected by a pipe, and both the oil pump 504 and the plate heat exchanger 505 are connected by a pipe to the fixed shell 3.

[0026] More specifically, when the waste heat gas generated by the central air conditioning enters the fixed channel 501, multiple baffles 502 block the waste heat gas, causing it to dissipate slowly. The fixed channel 501 is heated by the conduction of the waste heat gas, and the heat dissipation fins 503 absorb the heat. There is heat transfer oil in the cavity between the fixed shell 3 and the fixed channel 501. The heat transfer oil absorbs the heat from the heat dissipation fins 503. The heated heat transfer oil is circulated by the oil pump 504. The high-temperature heat transfer oil enters the plate heat exchanger 505, where the heat is transferred and utilized.

[0027] The waste heat recovery mechanism 5 is equipped with an auxiliary mechanism 6 for stirring and turbulence, and the auxiliary mechanism 6 is located on top of the base plate 1; for example Figure 2-4 As shown, specifically, the auxiliary mechanism 6 includes a support base 601, which is fixedly installed inside the fixed channel 501. A T-shaped circular groove is formed on the surface of the support base 601. A T-shaped shaft 602 is rotatably installed on the inner wall of the T-shaped circular groove. A fan blade 603 is fixedly installed on the surface of the T-shaped shaft 602, and the fan blade 603 is distributed in the center of the fixed channel 501.

[0028] More specifically, the airflow of waste heat gas from the central air conditioning system drives the fan blades 603 to rotate, which in turn drives the T-shaped shaft 602 to rotate. Due to the support base 601 and the T-shaped shaft 602, the fan blades 603 can be stably supported. The rotating fan blades 603 can stir and turbulent the airflow, disrupting the laminar flow and increasing the turbulence. The interior of the fixed channel 501 can come into more full contact with the hot air, so that the heat is more evenly distributed across the entire cross-section of the fixed channel 501, thereby improving the overall heat exchange efficiency.

[0029] In summary, during use, when the waste heat gas generated by the central air conditioning enters the waste heat recovery mechanism 5 through the connecting pipe 4, the waste heat recovery mechanism 5 absorbs, converts, and recovers the heat, which can be reused. The waste heat gas generated by the central air conditioning will drive the auxiliary mechanism 6 to disrupt the laminar flow state, increase the airflow turbulence, and make the heat more evenly distributed to the waste heat recovery mechanism 5, thereby improving the overall heat exchange efficiency. This achieves the recovery and utilization of the heat energy of the waste heat gas generated by the central air conditioning, saving energy consumption and demonstrating strong practicality.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
