As shown in fig. 3, in the air mixing and temperature adjusting mode, the temperature and humidity of the indoor air are adjusted while the fresh air is introduced, and the energy of the exhausted air is recycled for the second time, so that the energy consumption is reduced. Taking a common three-person family as an example, the requirement on fresh air volume is about 150m3H, and in this case, 500-600m is required to satisfy the refrigeration requirement3The air volume per hour. Obviously, the air quantity of the fresh air is difficult to satisfyThe requirement of daily refrigeration of users, so we introduce partial exhaust air and fresh air to mix together for refrigeration. In the air mixing refrigeration mode, the first air valve 51 is opened, a part of the exhaust air passes through the internal circulation air duct 50 and then is mixed with the fresh air, and then is blown to the fresh air heat exchanger 41 to be subjected to temperature adjustment, while the other part of the exhaust air firstly passes through the heat exchange core 30 to realize the first energy recovery, and then passes through the exhaust air heat exchanger 42 to realize the second energy recovery, and then is discharged.
As shown in fig. 4, in the internal circulation temperature adjustment mode, when the user does not need to exchange indoor and outdoor air, in order to avoid the temperature and humidity coincidence caused by the fresh air entering the room, the internal circulation temperature adjustment mode is started, and the mode can be understood as an air conditioner and an air purifier. The fresh air is not introduced, and only the indoor air is purified and the temperature is adjusted. The tuyere fourth air valve 24 and the tuyere third air valve 14 are closed, and the first air valve 51 is opened.

As shown in fig. 5, in the constant temperature dehumidification mode, this mode is used to realize the dehumidification effect at a constant temperature, and when the constant temperature dehumidification is required to be realized in a general dehumidifier, the temperature is first reduced to remove moisture and then the temperature is raised to the room temperature through two heat exchangers. And the utility model discloses utilize the full heat transfer core in the new fan, saved the energy that the part intensification process consumed, specifically realize the principle as follows: the second damper 61 is open and the tuyere fourth damper 24 and the tuyere third damper 14 are closed. Indoor air enters the machine from the air exhaust air inlet 21, firstly passes through the heat exchange core 30, then passes through the air exhaust heat exchanger 42, and then is used as an evaporator to cool and separate out moisture, the air after cooling and dehumidification enters the heat exchange core 30 again through the dehumidification air duct 60 to raise the temperature, and then is used as a condenser to heat again and return to the original temperature through the fresh air heat exchanger 41, so that constant temperature dehumidification is realized.
According to the above, the technical scheme of the utility model, realized refrigeration, heat, fresh air dehumidification, multiple functions in an organic whole such as constant temperature dehumidification, new trend. The combination of the functions can be independently used without mutual restriction, and the combination can effectively reduce the energy consumption of refrigeration and dehumidification.
