Description

Technical Field

[0001] The utility model relates to the technical field of heating, ventilation and air conditioning, and in particular to a waste heat recovery heating device. Background Art

[0002] HVAC is a central air conditioner for each household. The biggest feature of central air conditioner is that it can create a comfortable indoor environment. The common split air conditioner in the home can only solve the problem of heating and cooling, but cannot solve the air treatment process. HVAC can solve the above problems very well.

[0003] The air treatment process has the following steps: first, after the air comes in, in addition to introducing fresh air, the air can be cooled and then filtered. After filtering, several major features are added: first, an electronic dust collector is added, which can mainly capture very small particles of dust. Generally speaking, it can capture one micron dust, and most of the dust within the range are bacteria, viruses, smoke, or odors, which can be filtered out; the other is to add a humidification device, which can create a relative humidity of about 40% in our room, so that people will feel very comfortable.

[0004] However, the existing HVAC has a common problem of all air conditioners, that is, when heating, the air it inhales is from above it. As we know, cold air is heavier than hot air, so the proportion of cold air contained in the intake air is very small, which is why the heating time is long. For this reason, we propose a waste heat recovery heating device to improve the heating effect and simultaneously utilize the waste heat resources. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a waste heat recovery heating device to solve the technical problems mentioned in the above background.

[0007] By adopting the above technical solution, the waste heat of the HVAC is used to preheat the cold air, thereby improving the quality and efficiency of heating, and the cold air at the bottom of the room can be extracted, thereby further improving the quality of heating.

[0008] The utility model is further configured such that a water cavity is opened inside the air guide plate, and the water cavity is filled with a water source, a U-shaped tube immersed in the water source is also provided inside the air guide plate, and an air duct extending to the outside is installed at one end of the U-shaped tube, and an exhaust pipe connected to the air intake pipe is installed at the other end of the U-shaped tube.

[0009] By adopting the above technical solution, the cold air can be preheated.

[0010] The utility model is further configured such that an air suction box is installed at the bottom end of the air conditioner indoor unit, and a suction fan is installed inside the air suction box, the bottom end of the air suction box is connected to multiple groups of threaded pipes, the outer wall of the air suction box is connected to an air outlet pipe connected to the inside of the air suction box, and the air outlet pipe is connected to the air induced air duct.

[0011] By adopting the above technical solution, the cold air at the bottom of the room can be sucked in.

[0012] The utility model is further configured that an air cavity is opened inside the air intake box, and a filter screen and an activated carbon layer are installed in the air cavity in sequence from top to bottom.

[0013] By adopting the above technical solution, the gas can be purified.

[0014] The utility model is further configured that an air outlet valve is provided at the bottom end of the air inlet box, and the air outlet valve is connected to the air inlet system of the air conditioner indoor unit through a pipeline.

[0015] By adopting the above technical solution, the air supply effect for the indoor unit of the air conditioner is achieved.

[0016] In summary, the utility model mainly has the following beneficial effects:

[0017] 1. The utility model sets an air guide plate and an air suction box. First, when the HVAC is heating, hot air will be blown out through the air outlet to heat the room. In this process, the air guide plate will continue to be affected by the hot air, so the water source inside it will be heated. Then the threaded pipe will be stretched to 30 cm above the ground. The suction fan in the air suction box will draw the cold air at the bottom of the room and discharge it to the induced air pipe through the air outlet pipe. Further, the gas will flow into the U-shaped pipe. In this process, the water source will preheat the cold air. The preheated gas will enter the air intake box through the exhaust pipe and the air intake pipe, and finally enter the air conditioner through the air outlet valve for use, thereby improving the quality and efficiency of heating, and utilizing the waste heat, which is energy-saving and environmentally friendly.

[0018] 2. The utility model provides an air intake box, a filter and an activated carbon layer. After the gas enters the air intake box, the gas will flow in the air cavity and then pass through the filter and the activated carbon layer. Under the action of the filter and the activated carbon layer, the gas will be highly purified, thereby further improving the air purification quality of the HVAC. BRIEF DESCRIPTION OF THE DRAWINGS
