Description

Technical Field

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

[0002] HVAC systems control air temperature and humidity, improving indoor comfort and are a crucial component of medium- to large-scale industrial buildings and office structures (such as skyscrapers). During summer use, HVAC units often blow large amounts of hot air. To improve resource efficiency, an HVAC heat recovery device is required.

[0003] However, the existing heat recovery device has a weak insulation function. When the device uses cold water and hot air to exchange heat, the water needs to be stored. During the storage process, the heat of the water will continue to be lost as time goes by, resulting in poor heat exchange quality of the device, which is not conducive to improving resource utilization efficiency. Not only that, the existing heat recovery device has poor working efficiency. When in use, the hot air flows in the device to exchange heat with the cold water. The slow air speed during the heat exchange work will result in low heat exchange efficiency, which in turn leads to poor working efficiency of the device. Utility Model Content
