The outlet channel and the fresh air outlet channel are respectively provided with an exhaust fan and an air supply fan.

The operating principle of the unit, in the winter heating or summer air conditioning season, the outdoor fresh air enters the fresh air inlet channel through the fresh air inlet, and then is filtered and cleaned by the filter, and enters the fresh air channel of the energy recovery heat exchanger; while the indoor air enters the exhaust through the exhaust inlet. The inlet channel, and then the indoor air enters the exhaust channel of the energy recovery heat exchanger through the filter. The indoor air in the exhaust channel and the outdoor fresh air in the fresh air channel perform energy recovery and heat exchange, but in severe cold or hot seasons, after energy recovery When the heat exchange of the heat exchanger cannot meet the requirements of the indoor temperature, the outdoor fresh air enters the fresh air outlet channel after passing through the energy recovery heat exchanger, and is heated or cooled by the cooling and heating coil in the fresh air outlet channel to achieve the indoor temperature requirement, and then passes through the fresh air outlet channel. The air supply fan is sent into the room from the fresh air outlet, and the indoor air is discharged into the exhaust outlet channel through the energy recovery heat exchanger, and then discharged to the outside through the exhaust air outlet through the exhaust fan.

Preferably, a bypass air channel is added between the fresh air inlet channel and the fresh air outlet channel, and a bypass air valve is arranged in the bypass air channel. In the transitional season, when the temperature difference between indoor and outdoor is almost zero, the bypass ventilation valve can be opened, and the fresh air directly enters the fresh air inlet channel from the fresh air inlet without passing through the energy recovery heat exchanger, and then enters the fresh air outlet channel through the bypass ventilation valve, and then is supplied by the supply air. The fan is sent into the room through the fresh air outlet, which greatly reduces the energy consumption, reduces the operation cost for the customer, has significant energy saving effect and is more environmentally friendly.

Preferably, filters are provided at the inlet end of the fresh air channel and the inlet end of the exhaust channel of the energy recovery heat exchanger to ensure that the fresh air entering the energy recovery heat exchanger and the indoor air are clean gases.

Compared with the prior art, the utility model has the following beneficial effects:

The utility model has a reasonable structure design, and can realize multiple uses of one machine. It can not only complete the most basic energy recovery and ventilation, but also can be used in a cooling or heating environment. Heating, which has reached the indoor temperature, can also be used in transitional seasons. Open the bypass ventilation valve, so that the outdoor fresh air can enter the room directly through the bypass ventilation valve and the air supply fan, without passing through the energy recovery heat exchanger, which greatly reduces the energy consumption. Energy consumption, reduce operating costs for customers, significant energy-saving effect, more environmentally friendly.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described:

1 and 2 , the multifunctional fresh air ventilator of the present invention includes a main body casing 1, and the interior of the main body casing 1 is divided into a fresh air inlet channel 3 by a fresh air partition plate 15 and an exhaust air partition plate 17 , the fresh air outlet channel 9, the exhaust air inlet channel 7 and the exhaust air outlet channel 2, and the main body shell 1 is provided with an energy recovery heat exchanger 6, and the fresh air inlet channel 3 and the fresh air outlet channel 9 pass through the energy recovery heat exchanger 6. The fresh air channel is connected, the exhaust air inlet channel 7 is connected with the exhaust air outlet channel 2 through the exhaust air channel of the energy recovery heat exchanger 6, the fresh air inlet channel 3, the fresh air outlet channel 9, the exhaust air inlet channel 7 and the exhaust air outlet channel 2 are respectively Connecting the fresh air inlet 4, the fresh air outlet 11, the exhaust air inlet 8 and the exhaust air outlet 14, the fresh air outlet passage 9 is provided with a cooling and heating coil 12, and the exhaust air outlet passage 2 and the fresh air outlet passage 9 are respectively provided with an exhaust fan 13 and blower fan 10.
