Detailed Description

Next, the specific structure of the air inlet box 200 and the air conditioning unit provided in the embodiment of the present application will be described in detail with reference to the drawings.

Fig. 1 is a schematic structural diagram of an air conditioning unit in an embodiment of the present application. As shown in fig. 1, the air conditioning unit in the embodiment of the present application includes: an air inlet box 200 and an indoor unit 100. The air inlet box 200 is connected to the outside of the room through a duct 300 penetrating through the wall of the room, so that the outdoor air can be introduced into the indoor unit 100 when the outdoor temperature is low, thereby reducing the energy consumption of the indoor unit 100.

The indoor unit 100 includes a casing 110, and a compressor 120, a heat exchanger 130, and a blower 140 provided in the casing 110. A first air duct 111 is arranged in the housing, the first air duct 111 is provided with a second air inlet 112 at the top of the casing 110, and an air supply outlet 113 is arranged at the bottom of the casing 110. The second air valve 114 is arranged on the second air inlet 112, the second air valve 114 is provided with a blade with an adjustable angle, and the second air valve 114 can change the opening degree of the second air inlet 112 by adjusting the angle of the blade, so that the air inlet amount of the second air inlet 112 can be adjusted.

The air outlet 113 is connected with a cold air duct 400 in the machine room, and the blower 140 is disposed at a position corresponding to the air outlet 113, and can suck indoor air through the first air duct 111 and send the air into the cold air duct 400. The heat exchanger 130 is disposed in the middle of the first air duct 111, the heat exchanger 130 is connected to the compressor 120, a refrigerant circulates between the heat exchanger 130 and the compressor 120, and the refrigerant is vaporized in the heat exchanger 130 to absorb a large amount of heat, so as to exchange heat with air passing through the first air duct 111, and the air is sent into the cold air duct 400 through the air supply opening 113 after the temperature of the air is reduced. The air with the reduced temperature can be conveyed to different positions in the machine room through the cold air duct 400, so that the machine room is cooled.

The first air duct 111 is further provided with a first air inlet 115 at a side portion of the outer case 110, and the first air inlet 115 is located between the blower 140 and the heat exchanger 130 and is used for connecting with a fresh air outlet 213 of the below-described air inlet box 200.

Fig. 2 is a schematic view of the internal structure of the air inlet box 200 in fig. 1. As shown in fig. 1 and 2, the air inlet box 200 includes: a case 210, and an air filter 220 disposed in the case 210. Wherein, set up second wind channel 211 in the box 210, second wind channel 211 is provided with new trend entry 212 and new trend export 213 on box 210, and new trend entry 212 can pass the computer lab wall through equipment such as pipeline 300 and be connected with outdoor, and new trend export 213 is connected with first air inlet 115. Accordingly, when the outdoor air temperature is low, the indoor temperature can be reduced by introducing the low-temperature outdoor air into the indoor space, thereby reducing the energy consumption of the indoor unit 100.

The air filter 220 may be a bag filter or other filter, and is not limited thereto. Air cleaner 220 sets up in second wind channel 211, and when outdoor air passed through second wind channel 211, air cleaner 220 can filter outdoor air to it is inside to avoid the impurity in the outdoor air to go into the computer lab, pollutes the inside air of computer lab, influences the normal work of computer lab equipment.

The fresh air outlet 213 is further provided with a first air valve 214, and the structure of the first air valve 214 is the same as that of the second air valve 114, which is not described herein again. The opening degree of the fresh air outlet 213 can be adjusted by the first air valve 214, so that the air output of the fresh air outlet 213 can be adjusted.

As shown in fig. 1, after the blower 140 is operated, the air in the second air duct 211 can be sent into the cold air duct 400 in the machine room, so that negative pressure is generated in the second air duct 211 and the first air duct 111 connected to the second air duct 211. Therefore, indoor air enters the first air duct 111 through the second air inlet 112, is subjected to heat exchange by the heat exchanger 130 and is cooled and then is sent to the cold air duct 400 through the air supply outlet 113; outdoor air enters the second air duct 211 through the fresh air inlet 212, and after being filtered by the air filter 220, the outdoor air enters the first air duct 111 through the fresh air outlet 213 and is sent into the cold air duct 400 through the air supply outlet 113.

Therefore, when the outdoor temperature is higher than the first temperature threshold, for example, the outdoor temperature is higher than the indoor temperature, the first air valve 214 may be controlled to close the fresh air outlet 213, and only the heat exchanger 130 cools the indoor air and then sends the cooled air duct 400 to cool the room.

When the outdoor temperature is lower than the second temperature threshold, for example, the outdoor temperature is lower than the temperature of the indoor air after the heat exchange with the heat exchanger 130 in the first air duct 111, the second air valve 114 may be controlled to close the second air inlet 112, and at the same time, the compressor 120 is controlled to stop working, and the blower 140 sucks the outdoor air into the first air duct 111 through the second air duct 211, and sends the air into the cold air branch duct to cool the interior of the machine room.

When the outdoor temperature is higher than the second temperature threshold and lower than the first temperature threshold, for example, the outdoor temperature is higher than the indoor air temperature in the first air duct 111 after heat exchange with the heat exchanger 130, and is lower than the indoor temperature, the opening degree of the fresh air outlet 213 is controlled by the first air valve 214, so that the ratio of the outdoor air to the indoor air is adjusted, the temperature of the room in the machine room can be reduced by the outdoor air, and the energy consumption of the air conditioning unit is reduced.

In some embodiments, the first gas inlet 115 may also be disposed at a position between the second gas inlet 112 and the heat exchanger 130, which is not limited thereto. Therefore, indoor air and outdoor air need to be sent into the cold air duct 400 after heat exchange through the heat exchanger 130, and then the temperature of the machine room is reduced.

When the outdoor temperature is lower than the indoor temperature, the second damper 114 may be controlled to be closed and the first damper 214 may be controlled to be opened. Therefore, the air conditioning unit obtains air from the outdoor with lower temperature, the required power of the air conditioning unit is reduced when the air temperature is reduced to the threshold temperature, and the energy consumption of the air conditioning unit can be reduced.

Thereby be convenient for more carry out erection joint to air inlet box 200, improved air inlet box 200 to the adaptability of installation environment.

As shown in fig. 1, 3 and 4, the first inlet 212a and the second inlet 212b are further provided with a tuyere flange 230 and a tuyere guard 240. Wherein, both the tuyere flange 230 and the tuyere baffle 240 can be installed with the first inlet 212a and the second inlet 212b, the tuyere flange 230 is used for the connection between the pipeline 300 and the first inlet 212a or the second inlet 212b, and the tuyere baffle 240 is used for closing the first inlet 212a or the second inlet 212 b.

The tuyere flange 230 and the tuyere block 240 may be configured to have the same or compatible installation structure, and the specific installation positions of the tuyere flange 230 and the tuyere block 240 may be that, as shown in fig. 1, the duct 300 is connected to the first inlet 212a through the tuyere flange 230, and the tuyere block 240 is disposed at the second inlet 212b to close the second inlet 212 b; the specific installation position of the tuyere flange 230 and the tuyere block 240 may also be such that the duct 300 is connected to the second inlet 212b through the tuyere flange 230 as shown in fig. 4, and the tuyere block 240 is disposed at the first inlet 212a to close the first inlet 212 a.
