2. Complete fresh air natural cooling
When the outdoor environment temperature meets the natural cooling condition, the combined air conditioning unit operates in a natural cooling mode. As shown in fig. 10, the condensing air intake valve 217 and the indoor air return valve 218 are closed, the fresh air valve 219, the indoor air exhaust valve 215 and the air exhaust port air valve 118 are opened, the compressor 280 is closed, outdoor fresh air enters the third chamber 220 of the evaporation unit through the fresh air valve 219, flows through the filter 240 and the evaporator 230 in sequence and enters the air supply unit 300, and then is supplied to the indoor air through the air supply port 311 under the action of the air supply fan 320; the indoor return air enters the first chamber 150 of the condensing unit through the first air return opening 117 and the second air return opening 114, then flows through the first chamber 150 of the condensing unit and the first chamber 260 of the evaporating unit in sequence, enters the second chamber 250 of the evaporating unit through the indoor exhaust valve 215, then flows through the condenser 130 and the condensing fan 140 in sequence, and finally is discharged from the indoor load through the exhaust air outlet valve 118. Therefore, indoor hot air is replaced by continuously entering outdoor low-temperature air to realize cooling of the inside of the data center machine room.
In addition, when the outdoor temperature is low, the supply air temperature can also be adjusted by opening the indoor return air valve 218.
3. Partial natural cooling mode
When the outdoor temperature is in a proper range, the unit operates in a partial natural cooling mode. As shown in fig. 11, the condensing air intake valve 217, the indoor air return valve 218, the air exhaust port air valve 118, the fresh air valve 219 and the indoor air exhaust valve 215 are opened, the compressor 280 is opened, outdoor fresh air enters the second chamber 250 of the evaporation unit through the condensing air intake valve 217, indoor return air enters the second chamber 250 of the evaporation unit through the indoor air exhaust valve 215, and the two parts of air sequentially flow through the condenser 130 and the condensing fan 140 and finally are exhausted out of the indoor load through the air exhaust port air valve 118;
the outdoor fresh air enters the third chamber 220 of the evaporation unit through the fresh air valve 219, the indoor return air enters the third chamber 220 of the evaporation unit through the indoor return air valve 218, and the two gases sequentially flow through the filter 240 and the evaporator 230 to enter the air supply unit 300, and then are supplied to the indoor through the air supply port 311 under the action of the air supply fan 320.
Therefore, by controlling the opening and closing states of the condensation air inlet valve 217, the indoor air return valve 218, the fresh air valve 219, the indoor air exhaust valve 215 and the compressor 280, the combined air conditioning unit can be switched between a mechanical refrigeration mode, a natural cooling mode and a partial natural cooling mode, and the outdoor natural cooling source can be fully utilized to reduce the temperature in a data center machine room in winter and in a transition season with lower outdoor temperature, so that the flexibility of the operation mode of the combined air conditioning unit is improved and the energy is saved. In addition, the independent fresh air intake and independent air exhaust functions can be realized by controlling the opening and closing states of the four air valves, namely the condensation air intake valve 217, the indoor return air valve 218, the fresh air valve 219 and the indoor air exhaust valve 215.
