Description

technical field [0001] The invention relates to the technical field of air conditioning and ventilation, in particular to a new fan. Background technique [0002] The traditional fresh air fan is only installed with a fan in the casing. Although it can introduce outdoor fresh air, it lacks the function of heat preservation and noise reduction, so that when the outdoor cold air enters the body, if the indoor temperature is too high or too low, condensation will occur on the body. Water (cold bridge) can corrode the body and motor, and the dripping of condensed water will also lead to mildew of interior decoration materials, affecting people's living and health. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a fresh air blower to solve the above-mentioned problems in the background art. [0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a fresh air fan, comprising a...
