Cabinet type fresh air ventilator

Abstract

The invention relates to a cabinet type fresh air ventilator. The cabinet type fresh air ventilator is of a multilayer layout structure, and the layers are mutually separated; the cabinet type fresh air ventilator comprises an exhaust channel and a fresh air channel; the cabinet type fresh air ventilator is divided into a first layer, a second layer and a third layer from bottom to top, and partition plates are arranged among the layers and provided with open holes enabling the adjacent layers to communicate; an air inlet section of the fresh air channel is arranged in the first layer and provided with a fresh air inlet and a first filter; a cold-hot exchanger and an air inlet section of the exhaust channel are arranged in the second layer, and the air inlet section of the exhaust channelis provided with an exhaust inlet and a second filter; and the third layer is provided with a first fan and a second fan which are arranged in the fresh air channel and the exhaust channel correspondingly in a mutual-separation mode, an air outlet of the first fan communicates with the indoor space, and an air outlet of the second fan communicates with the outdoor space. The cabinet type fresh airventilator is orderly and compact in overall layout.

Description

technical field [0001] The invention relates to air purification equipment, in particular to a cabinet-type fresh air fan. Background technique [0002] In recent years, indoor air quality has attracted more and more attention. At present, there are mainly two types of purification equipment to improve air quality: indoor air purifiers that can only purify indoor air, and fresh air fans that can exchange indoor and outdoor air. The indoor air purifier has no ventilation function, and it cannot change the indoor air composition (carbon dioxide, etc.), while the fresh air fan can force the indoor air to be partially discharged to the outside through the indoor and outdoor two-way ventilation, and at the same time introduce the outdoor fresh air. , thereby changing the composition of the indoor air. [0003] Since fresh air fans have more functions than indoor air purifiers, their functional modules and structural configuration are also more complex than indoor air purifiers....
