Problems solved by technology

[0002] At present, when the fresh air air conditioner provides fresh air to the room, it cannot take into account the fresh air volume and temperature control. For example, when the outdoor air temperature is high and the fresh air supply temperature is too high, the fresh air volume is reduced to reduce the fresh air supply temperature. As a result, it is impossible to provide enough fresh air to the room, reducing the fresh air volume will reduce the heat exchange capacity, and when the room needs cooling capacity, it cannot meet the demand; when the fresh air supply temperature is too low, take frequent start and stop compressors or increase the fresh air supply fan The speed is used to increase the fresh air volume. Increasing the air volume increases the heat exchange capacity. When the room does not need cooling capacity, it provides more cooling capacity to the room. At the same time, the frequent start and stop of the compressor will cause large fluctuations in the fresh air supply temperature, affecting The comfort of the user, and the frequent start and stop of the compressor will reduce the service life and consume more energy

Embodiment 1

[0045] figure 1 Show the structural representation of the fresh air air conditioner of embodiment 1 and embodiment 2; figure 2 show figure 1 Schematic diagram of the local structure of A; Figure 3 to Figure 5 show figure 1 Schematic diagram of the angle range of the medium-mix air damper.

[0046] Such as figure 1 and image 3 As shown, the fresh air air conditioner according to one embodiment of the present invention includes: a condenser 302 and an evaporator 202; The air outlet 104, the indoor side of the housing 10 is provided with an indoor air inlet 106 and an indoor air supply outlet 108; the housing 10 includes: an evaporator chamber 20, which communicates with the outdoor air inlet 102 and the indoor air supply outlet 108, and the evaporator chamber 20 is provided with The evaporator 202; the condenser chamber 30 is connected to the outdoor air outlet 104, and the condenser chamber 30 is provided with a condenser 302; the air mixing chamber 40 is connected to ...

Embodiment 2

[0054] Such as Figure 1 to Figure 5 As shown, the fresh air air conditioner according to an embodiment of the present invention also includes: a blower 204 disposed in the evaporator chamber 20, the air outlet of the blower 204 is connected to the indoor air supply port 108; an exhaust fan 304 is disposed in the condenser chamber 30, the air outlet of the exhaust fan 304 is connected with the outdoor air outlet 104.

[0055] By setting the blower 204, the flow efficiency of the fluid flowing into the room from the evaporator cavity 20 through the indoor air outlet 108 is increased, and by setting the exhaust fan 304, the flow efficiency of the fluid flowing from the condenser cavity 30 to the outside through the outdoor air outlet 104 is increased. , further, by setting the blower 204 and the exhaust fan 304, the circulation efficiency of the indoor fresh air volume is increased.

Embodiment 3

[0057] Figure 6 A schematic flow chart of the air supply method in Embodiment 3 is shown.

[0058] Such as Figure 6 As shown, the air supply method according to one embodiment of the present invention is used for the fresh air air conditioner in any one of the technical solutions of the first aspect, including:

[0059]Step S602, after the fresh air conditioner runs for a preset time, obtain the indoor temperature, and determine the absolute value of the temperature difference between the indoor temperature and the preset temperature;

[0060] Step S604, judging the relationship between the absolute value of the temperature difference and the temperature difference threshold;

[0061] Step S606, when the absolute value of the temperature difference is greater than the temperature difference threshold, adjust the damper angle of the mixed air damper of the fresh air conditioner according to the magnitude relationship between the indoor temperature and the preset temperature...
