Embodiment 1

[0052] Such as figure 1 As shown, the air conditioning system disclosed in this embodiment includes a compressor 1 , an outdoor heat exchanger 8 , a refrigerant pump 12 , and an indoor heat exchanger 20 connected in series in sequence. The inlet of the compressor 1 is connected in series with the second one-way valve 24, and then the compressor 1 and the second one-way valve 24 are connected in parallel with the first solenoid valve 2, and the branch where the first solenoid valve 2 is located constitutes the first branch, and the second A solenoid valve 2 is the first switching device. By controlling the switch of the first solenoid valve 2, the compressor 1 can be switched into the air conditioning system. When the first solenoid valve 2 is opened, the refrigerant will pass through the second compressor instead of the compressor 1. A first branch where the solenoid valve 2 is located, when the first solenoid valve 2 is closed, the refrigerant will pass through the compressor...

Embodiment 2

[0071] Such as figure 2 As shown, it is the air conditioning system disclosed in this embodiment, which includes a compressor 1, a second electromagnetic valve 3, a first shut-off valve 4, a second shut-off valve 5, a third electromagnetic valve 6, an outdoor heat exchanger 8, Refrigerant pump 12, fifth solenoid valve 14, third stop valve 15, fourth stop valve 16, sixth solenoid valve 17, electronic expansion valve 19, indoor heat exchanger 20, and indoor heat exchanger 20 is connected to the compressor 1 to form a complete circuit. Same as the first embodiment of the device, the outdoor unit of the air-conditioning system in this embodiment also includes an outdoor fan 7, an outdoor unit heating device 9 and a temperature sensing device 10, wherein the outdoor unit heating device 9 and the temperature sensing device 10 are arranged outside the outdoor unit. At the air inlet position of the heater 8. The indoor unit of the air conditioning system also includes an indoor uni...

Abstract

The invention discloses an air conditioning system and the controlling method thereof. The air conditioning system comprises a refrigerant circulation circuit which is provided with an indoor heat exchanger, an outdoor heat exchanger and a compressor. Besides, the refrigerant circulation circuit is provided with a supercharging device for driving refrigerant cycle that can be in series with the compressor. The controlling method of the air conditioning system is divided into the working mode of the compressor, the alternate mode of the compressor and the refrigerant pump, the mode of the refrigerant pump and the co-working mode of compressor and refrigerant pump according to the difference between the length of the connecting pipe between the indoor heat exchanger and the outdoor heat exchanger and height between the indoor heat exchanger and the outdoor heat exchanger. The air conditioning system and the method thereof have solved the low working efficiency and the energy efficiency ratio problems causing by the low environmental temperature and the long distance between the indoor and outdoor machine and the like, thereby being more reliable and economical.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning system and a control method thereof. Background technique [0002] With the development of large-scale and large-scale data centers, data centers and similar places will generate relatively stable heat due to the long-term operation of internal equipment, which will cause the temperature of data centers and similar places to rise and the relative humidity to drop, which is not conducive to The stable operation of its internal equipment. In order to maintain the reliability of equipment in data centers and similar places, the air conditioners configured in these places must be kept in cooling operation all year round. [0003] The air conditioner is the guarantee for the stable operation of equipment in data centers and similar places, and it is also one of the main power-consuming equipment in data centers and similar places. s concern. [0004] Wh...
