Problems solved by technology
The problem is: single function, such as heat exchange between outdoor air and indoor air, outdoor air enters the room, and indoor air is discharged outside; in the case of bad external environment, or by closing the outdoor air inlet to prevent pollution or heat exchanger condensation resulting insecurity
However, it is equivalent to the shutdown of the heat exchanger, which does not play the role of ventilation and heat exchange.

A total-heat fresh air exchanger with an internal circulation air purifying function comprises a shell, an air filtering device, a heat exchanger and an air supply device. An outdoor air inflow portion and an indoor air inflow portion are arranged on the air filtering device. The heat exchanger is matched with the air supply device. The air filtering device, the heat exchanger and an exhaust device are sequentially arranged in the shell. The air supply device comprises a first draught fan and a second draught fan. The total-heat fresh air exchanger further comprises a switching device and an exhaust switching device. In a first working manner, indoor air and outdoor air are filtered and exchange heat, the indoor air is exhausted outdoors, and the outdoor air is exhausted indoors. In a second working manner, the indoor air is fed and filtered, the outdoor air is fed and filtered, the indoor air and the outdoor air are totally exhausted indoors, and outdoor air feeding plays a role in supplementing fresh air. It is guaranteed that the indoor air is fresher and more healthy, the parallel-connection double-draught-fan air way effect can be fully used, and energy saving and high efficiency are achieved.
Description
technical field [0001] The invention relates to an indoor air and an indoor air purification device. Background technique [0002] In the current prior art, a total heat exchanger includes a shell, a heat exchange base heat exchanger, and an air supply device. The heat exchange base has an outdoor air intake portion and an indoor air intake portion; the heat exchanger is in the shape of a rhombus, etc. The heat exchanger has a first passage and a second passage, and the outdoor air intake part and the indoor air intake part communicate with the first and second passages respectively; the heat exchanger cooperates with the air supply device; the air filter device, the heat exchanger and the discharge device are sequentially arranged in the housing. The problem is: single function, such as heat exchange between outdoor air and indoor air, outdoor air enters the room, and indoor air is exhausted outside; in the case of bad external environment, or by closing the outdoor air in...
