Abstract

The invention provides a device for the recovering and ventilating of air and air energy with a bypass defrosting function, relating to an air energy recovering and ventilating device and aiming at solving the problems that the existing air energy recovering and ventilating device can not be used normally at the cold area, the heat exchanging efficiency is reduced and the air exhaust quantity is reduced due to the defrosting. A heat exchanger frame is fixedly connected with the top end in a shell; the heat exchanger is arranged in the heat exchanger frame; an air exhaust fan is arranged in anair exhaust chamber; a new wind fan is arranged in a new wind chamber; an air exhaust outlet, a new wind outlet, a first duct outlet and a second duct outlet are respectively arranged on the heat exchanger frame; a bypass wind valve is arranged at the new wind inlet and is pivotally connected with the shell by a hinge; one end of a connecting rod is pivotally connected with the bypass wind valve and the other end thereof is pivotally connected with a sliding block; and the sliding block is connected with the output end of the motor by a key. The device can be shifted as a defrosting state andcan be also reverted to a heat-exchanging state after the defrosting is completed, thus leading the device to be normally used even at the cold areas in frosting winters.

Description

technical field [0001] The invention relates to an air and air energy recovery ventilation device. Background technique [0002] When the existing air energy recovery ventilation device is used in winter in severe cold and cold regions of our country, there is a problem of frosting. If the frost accumulation is not removed in time, it will block the air passage and reduce the heat transfer area, which will increase the air flow resistance and make ventilation difficult. The volume and heat transfer efficiency are significantly reduced. The reason for frosting is: when the indoor exhaust air passes through the heat exchanger, the temperature decreases. When the temperature of the humid air is lower than the surface temperature of the heat exchanger, frosting will occur on the cold surface. If the temperature of the cold surface is lower than that of the water At freezing temperatures, water vapor will condense and form frost on cold surfaces. The existence of the frost prob...
