Problems solved by technology

[0003] However, when the airflow passes through the heat exchanger, the fan often needs to output a large power consumption to ensure that the airflow passes through the heat exchanger smoothly. Therefore, during heat exchange, the power consumption of the new fan is relatively large.
And because generally in winter and summer, when the indoor and outdoor temperature difference is large, the heat exchanger has a high heat exchange recovery rate. In spring and autumn, there is generally no indoor heating or cooling, and the indoor and outdoor temperature difference is small. At this time, the effect of the heat exchanger is low, but it needs to consume more electric energy, and the electric energy paid is not proportional to the heat exchange energy obtained, resulting in energy waste

Abstract

The invention discloses a fresh air ventilator capable of reversing airflow and a reversing method. The fresh air ventilator comprises: a machine shell provided with an air exhaust channel and a fresh air channel, a first air exhaust branch and a second air exhaust branch are formed in the air exhaust channel, and a first fresh air branch and a second fresh air branch are formed in the fresh air channel; a heat exchanger which is arranged in the machine shell, wherein the heat exchanger is connected to the first exhaust branch and the first fresh air branch so as to conduct heat exchange on the waste air and the fresh air; and a reversing valve which is arranged on the air exhaust channel and the fresh air channel, wherein the reversing valve can be switched to a first state or a second state, and responds to state switching to conduct the first air exhaust branch and the first fresh air branch and cut off the second air exhaust branch and the second fresh air branch, or cut off the first air exhaust branch and the first fresh air branch and conduct the second exhaust branch and the second fresh air branch. The waste air and the fresh air can flow through or not flow through the heat exchanger according to needs, reasonable use is guaranteed, the service life is prolonged, and energy consumption of the suction ventilator is reduced.

Description

technical field [0001] The invention relates to the technical field of fresh air blowers, in particular to a fresh air blower with reversible air flow and a reversing method. Background technique [0002] The fresh air fan is an effective air purification equipment. It can circulate the indoor and outdoor air by setting the exhaust channel and the fresh air channel. Introduced into the room through the fresh air channel. In the prior art, in order to make the temperature of the incoming fresh air tend to be indoors, heat exchangers are usually arranged on the exhaust air channel and the fresh air channel, so that the exhaust air and the fresh air can exchange heat in the heat exchanger. [0003] However, when the airflow passes through the heat exchanger, the fan often needs to output a large power consumption to ensure that the airflow passes through the heat exchanger smoothly. Therefore, the power consumption of the new fan is relatively large during heat exchange. And ...
