Description

Technical Field

[0001] The utility model relates to the technical field of heat recovery and fresh air integrated machines, in particular to a fresh air condensation and exhaust heat recovery integrated machine. Background Art

[0002] The heat recovery fresh air fan introduces fresh air from the outside, passes through several filtering devices, and then exchanges heat with the indoor return air in the heat exchange device, thereby increasing (lowering) the fresh air temperature and reducing indoor energy consumption. The heat recovery fresh air fan is a device that uses the recovered exhaust heat (cold capacity) to reduce the indoor heating and cooling loads. It can not only introduce fresh air from the outside, but also greatly reduce energy consumption, which is environmentally friendly and energy-saving.

[0003] The current heat recovery and fresh air integrated machine requires the use of dual pipes for air intake and exhaust respectively, which results in the need for a large number of electronic components, increasing the overall cost and energy consumption of the machine. At the same time, a protective net is usually installed at the outward pipe mouth of the pipe to prevent foreign matter or large particles of dust from entering the pipe. The protective net needs to be cleaned regularly, which is also quite troublesome. Utility Model Content
