In addition, the device is mainly improved aiming at the condition that the temperature of the outdoor air is increased to be higher than the return air temperature of the indoor air so as to reduce the overall power consumption of the indirect evaporative cooling unit.
When the air inlet temperature of the first air channel of the heat exchange core body 3 is greater than the air inlet temperature of the second air channel, the first air valve 6 can be opened, at this time, as the first air valve 6 is arranged at the upstream of the condenser 7, the air resistance between the first air valve 6 and the condenser 7 is smaller, and outdoor air outside the box body can be directly introduced into the air inlet side of the condenser 7, namely, most of the outdoor air does not pass through the heat exchange core body 3, the heat load of the heat exchange core body 3 on the system can be ignored, and the mechanical cooling power consumption of the evaporator 4 and the condenser 7 can not be increased. Or, the first air valve 6 can be opened and the second air valve 1 can be closed at the same time, at this time, outdoor air enters the condenser 7 and the first fan 8 through the first air valve 6, that is, the outdoor air does not pass through the heat exchange core 3, and the heat exchange core 3 does not generate heat load on the system, so that the power consumption of mechanical cooling is not increased.

And, the air that gets into condenser 7 has not had the resistance of heat exchange core 3 for the total resistance of outdoor air reduces, and the consumption of first fan 8 reduces, improves whole energy.
In one embodiment, an air inlet filter screen 2 is arranged between the heat exchange core body 3 and the second air valve 1, so that impurities can be removed when outdoor air flows through the air inlet filter screen 2, the air in the first air channel is cleaner, and the air channel blockage of the heat exchange core body 3 is avoided.

It should be further noted that, besides the fact that the condenser 7 and the heat exchange core 3 are distributed in a vertically staggered manner, the condenser 7 can be directly arranged above the heat exchange core 3, and the first air valve 6 is arranged on one side of the condenser 7, so that outdoor air directly enters the condenser 7 through the first air valve 6, does not need to pass through the heat exchange core 3, and the condenser 7 and the heat exchange core 3 are arranged in such a way, so that the device has a more compact structure and occupies a smaller space.

It should be noted that, the evaporator 4 may be disposed below the heat exchange core 3, the air inlet side of the evaporator 4 is communicated with two sides of the heat exchange core 3, and, since the third air valve 9 and the fourth air valve 10 are disposed at two sides of the heat exchange core 3, the third air valve 9 and the fourth air valve 10 are all communicated with the evaporator 4 through the second cavity 12 to form a second bypass channel and a third bypass channel of the second air duct respectively, the structure is as shown in fig. 2 and 3, and the curve direction in the drawing is the indoor air flow track.
The second bypass channel and the third bypass channel of the second air channel have the function of bypassing the heat exchange core 3 through the third air valve 9 and/or the fourth air valve 10 when the third air valve 9 and/or the fourth air valve 10 is opened, so that indoor air does not pass through the heat exchange core 3, the total resistance is reduced, and the fan power is reduced.

It should be noted that, the bypass channel of outdoor air and the bypass channel of indoor air are both used to make air pass through the bypass channel directly without passing through the heat exchange core 3, so as to avoid negative work of the heat exchange core 3, reduce resistance of the whole machine, and reduce power consumption of the fan. Also, only the bypass passage of the outdoor air, or only the bypass passage of the indoor air, or both the bypass passage of the outdoor air and the bypass passage of the indoor air may be provided.

That is, when the outdoor air temperature rises to be higher than the indoor air return temperature, the heat exchange core 3 is stopped, and only the cooling system is used for cooling. And, the first damper 6 is opened; or the second air valve 1 is closed and the first air valve 6 is opened at the same time, so that the outdoor air enters the condenser 7 and the first fan 8 from the first air valve 6, most of the outdoor air does not pass through the heat exchange core 3 or the outdoor air does not pass through the heat exchange core 3 at all, the heat load generated or generated by the heat exchange core 3 on the system is negligible, the mechanical cooling power consumption is not increased, and meanwhile, the total resistance of the outdoor air is reduced, the power consumption of the first fan 8 is reduced, and the whole energy is improved.
In addition to the air conditioner, the present application also provides a control method applied to the air conditioner disclosed in the foregoing embodiment, where the control method includes:
when the air inlet temperature of the first air channel of the heat exchange core body 3 is greater than or equal to the air inlet temperature of the second air channel, the third air valve 9 and/or the fourth air valve 10 are/is opened so as to operate the cold compensation circulation loop.
Further comprises: the second damper 1 is closed and the first damper 6 is opened.
It should be noted that, by detecting the air inlet temperature of the first air duct and the air inlet temperature of the second air duct, it may be determined whether the air inlet temperature of the first air duct is greater than or equal to the air inlet temperature of the second air duct, if so, the second air valve 1 is controlled to be closed, the first air valve 6 and/or the third air valve 9 and the fourth air valve 10 are controlled to be opened, if not, the switching temperature is calculated, and the opening and closing of the second air valve 1, the first air valve 6, the third air valve 9 and the fourth air valve 10 are controlled according to the relation between the switching temperature and the air inlet temperature of the first air duct.
That is, when the air inlet temperature of the first air channel is smaller than the air inlet temperature of the second air channel, the control device calculates the switching temperature, and when the air inlet temperature of the first air channel is equal to the switching temperature, the control device controls the second air valve 1 to be closed and controls the first air valve 6 and/or the third air valve 9 and the fourth air valve 10 to be opened so as to enable the increased power consumption of the compressor to be equal to the reduced power consumption of the fan; when the air inlet temperature of the first air channel is higher than the temperature of the switching point, the second air valve 1 is controlled to be closed, and the first air valve 6 and/or the third air valve 9 and the fourth air valve 10 are controlled to be opened;
when the air inlet temperature of the first air channel is smaller than the temperature of the switching point, the second air valve 1 is controlled to be opened, and the first air valve 6, the third air valve 9 and the fourth air valve 10 are closed;
when the air inlet temperature of the first air channel is greater than or equal to the air inlet temperature of the second air channel, the second air valve 1 is controlled to be closed, and the first air valve 6 and/or the third air valve 9 and the fourth air valve 10 are controlled to be opened.
Wherein, the controlling the opening of the first air valve 6 and/or the third air valve 9 and the fourth air valve 10 comprises: a first mode of controlling the second damper 1 to be closed and the first damper 6 to be opened; a second mode of controlling the second damper 1 to be closed and controlling the third damper 9 and the fourth damper 10 to be opened; and a third mode of controlling the second damper 1 to be closed and controlling the first damper 6, the third damper 9 and the fourth damper 10 to be opened.
In the first mode, the first damper 6 is opened and the third damper 9 and the fourth damper 10 are closed, since the second damper 1 is closed, at which time outdoor air is taken in from the first damper 6, through the first cavity 11, into the condenser 7 and the first fan 8. That is, in the first mode, the outdoor air does not pass through the heat exchange core 3, and the heat exchange core 3 does not generate heat load on the system, so that the power consumption of mechanical cooling is not increased. And, the resistance of the heat exchange core body 3 is not used for outdoor air, so that the total resistance of the outdoor air is reduced, the power consumption of the first fan 8 is reduced, and the overall energy efficiency is improved.
In the second mode, since the second damper 1 is closed, the third damper 9 and the fourth damper 10 are opened, and the first damper 6 is closed, so that indoor air enters the evaporator 4 from the side of the heat exchange core 3 through the second cavity 12 and then flows out of the second fan 5. That is, in the second mode, the indoor air does not pass through the heat exchange core 3, so that the wind resistance of the indoor air can be reduced, the power consumption of the second fan 5 can be reduced, and the energy efficiency of the whole machine can be improved.
In the third mode, since the second damper 1 is closed, the third damper 9, the first damper 6 and the fourth damper 10 are all opened, at this time, outdoor air enters from the first damper 6, enters the condenser 7 and the first fan 8 through the first cavity 11, and indoor air enters the evaporator 4 from the side of the heat exchange core 3 through the second cavity 12, and then flows out from the second fan 5. I.e. the third mode combines the advantages of the first mode and the second mode.
In the use process of the device, the control device can compare and analyze the power consumption of the whole machine in three modes, and automatically select an operation mode with relatively lower power consumption of the whole machine to determine the control modes of the first air valve 6, the third air valve 9 and the fourth air valve 10.
It should be noted that the second damper 1, the first damper 6, the third damper 9, and the fourth damper 10 mentioned in the present document are only for distinguishing the difference in position, and are not sequentially distinguished.
