Description

Technical Field

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

[0002] HVAC is the name of a classification of work types in building equipment, mainly including heating, ventilation, and air conditioning. Air conditioning: referred to as air conditioning, is a building environment control system used to adjust the temperature, humidity, cleanliness and air flow rate in a room or space, and provide a sufficient amount of fresh air. It generally consists of two parts: an outdoor unit and an indoor unit. The outdoor unit of the air conditioner is also called the main unit. According to the refrigeration principle of the air conditioner, the main unit will discharge the hot air after heat exchange to the outside, so that the indoor unit can produce cold air after heat exchange.

[0003] A heat recovery device for a heating, ventilation and air conditioning system is disclosed in the Chinese utility model patent application publication specification CN215724034U. A fixing mechanism is provided inside the air conditioner outer unit body, a hood is provided on one side of the air conditioner outer unit body, the top of the hood is connected to an air suction pipe, one end of the air suction pipe is connected to a fan, the top of the fan is connected to an air supply pipe, the bottom end of the air supply pipe is connected to an insulation box, and one side of the insulation box is movably connected to an air outlet pipe. Compared with the prior art, the utility model can pump hot air into the insulation box for storage by providing a fan, an air suction pipe and an air supply pipe. When the pressure of the hot air in the insulation box increases, the hot air can be decompressed by providing a pressure reducing valve. By using the fixing mechanism, by pressing the pressing plate, the pressing plate drives the second spring and the clamping rod to move up and down, and the clamping rod drives the clamping block to move into the groove, so that the hood can be disassembled, and it can be conveniently disassembled when the hot air hood plate needs to be replaced.

[0004] However, the device also lacks the function of effectively filtering impurities in the hot air and improving the recycling quality. When in use, the recycled hot air contains impurities and dust, which affects the environment when it is used again, resulting in reduced recycling quality and the recycled hot air is not conducive to use. Not only that, the device also lacks the function of improving the efficiency of reuse after recycling. When in use, the recycled hot air can only be used in a separate pipe for reuse, and the utilization rate is reduced, which results in easy waste. Utility Model Content
