According to incomplete statistics, about 6800 communication machine rooms of operators in the whole country are counted, but the refrigeration structure of the communication machine rooms is incomplete due to the fact that the construction investment time of the communication machine rooms is early, meanwhile, the refrigeration structure of the communication machine rooms is different from that of a data center, and most of existing communication machine rooms adopt distributed air-cooled air-conditioning systems.
The distributed air-cooled air-conditioning system generally adopts a mode that the air-conditioning external units and the air-conditioning internal units are in one-to-one correspondence, and the adoption of the mode causes huge deployment quantity of the air-conditioning external units, so that the space of an external building of a communication machine room is limited, and the subsequent addition of the air-conditioning system is difficult to continue; the air conditioner internal unit is mostly room level air conditioner, and is far away from heat dissipation IT equipment, and IT is not good to lead to the circulation of air in the computer lab, and refrigeration efficiency is low, appears the overheated phenomenon of computer lab local space easily to distributing type forced air cooling air conditioning system does not possess the natural cooling function, leads to communication computer lab air conditioning system energy consumption high on the left.
For the reasons, when the air conditioning system of the communication machine room is installed, in order to respond to a low-carbon and environment-friendly call, the heat pipe and the compressor are mainly used for coupling refrigeration, and the following problems exist in two air conditioning modes: 1. only the refrigeration in a compressor mode or a heat pipe mode can be realized, and the better utilization of a natural cold source cannot be realized in the intermediate transition stage; 2. the amount of cooling between the compressor mode and the heat pipe mode cannot be better controlled to meet the refrigeration requirements of the machine room.
For the compressor mode and the heat pipe mode refrigeration of better nimble application air conditioner, also for better control computer lab refrigeration demand simultaneously, this application provides an air conditioner control system as shown in figure 2, the air conditioner control system that this application embodiment provided includes air conditioner end, power cabinet 3 and outdoor heat abstractor 7, and air conditioner end and outdoor heat abstractor 7 communicate through power cabinet 3.
The outdoor heat dissipation device 7 adopts a water-cooled heat dissipation device, the water-cooled heat dissipation device comprises a spraying device 6 and a plate-tube heat exchanger 8, the spraying device 6 is arranged above the plate-tube heat exchanger 8 and used for spraying and cooling the plate-tube heat exchanger 8, and air inlet airflow 9 enters from the lower part of the plate-tube heat exchanger 8.
The power cabinet 3 comprises a heat exchange unit 16, a compressor 10, a flow device 15, a gas pipeline and a liquid pipeline; the primary sides of the gas pipeline and the liquid pipeline are communicated with the tail end of the air conditioner, and the secondary sides of the gas pipeline and the liquid pipeline are communicated with the outdoor heat dissipation device.
A three-way valve 13 is arranged on the liquid pipeline, the inlet of the three-way valve 13 is connected with a liquid return pipe on the secondary side of the liquid pipeline, the first outlet of the three-way valve 13 is connected with the inlet on the primary side of a heat exchange unit 16 through the liquid pipeline, and the outlet on the primary side of the heat exchange unit 16 is connected with a liquid supply pipe 1 on the primary side of the liquid pipeline to form a heat pipe system.
A second outlet of the three-way valve 13 is connected in series with an inlet of the flow device 15 through a refrigeration pipeline, an outlet of the flow device 15 is connected with a secondary side inlet of the heat exchange unit 16, the compressor 10 is arranged on the refrigeration pipeline at the secondary side outlet of the heat exchange unit 16, and the refrigeration pipeline at the secondary side outlet of the heat exchange unit 16 is communicated with the steam supply pipe 4 at the secondary side of the gas pipeline, so that the air conditioning system is formed.
The gas pipeline and the liquid pipeline are connected through a branch provided with a bypass valve 14, the outlet of the branch is arranged between the first outlet of the three-way valve 13 and the heat exchange unit 16, and the inlet of the branch is communicated with the return pipe 2 on the primary side of the gas pipeline.
The heat exchange unit 16 is a plate heat exchanger for exchanging heat of two refrigerants; the compressor 10 is used for compressing low-pressure gas into high-pressure gas and driving a refrigerant to circulate in the air conditioning system; the flow device 15 is an electronic expansion valve and is used for adjusting the cooling capacity of the air conditioner; the outdoor heat radiator is a water cooling tower, and a plate-tube heat exchanger is arranged in the outdoor heat radiator and is used for enabling a refrigerant to exchange heat with the outside, so that the purpose of changing the state of the refrigerant is achieved.
In one possible design, for example, when the air conditioning system is in an air conditioning operation mode, the high-temperature gaseous heat flow at the air conditioning terminal is liquefied in the heat exchange unit 16 to release heat, and the refrigerant in a low-temperature liquid state flows back to the air conditioning terminal. The low-temperature liquid refrigerant of the outdoor heat sink 7 enters the heat exchange unit 16 to exchange heat with high-temperature gaseous heat flow, is evaporated and absorbed by the heat exchange unit 16 to become low-pressure gaseous refrigerant, is compressed into high-pressure gaseous refrigerant by the compressor 10, and is finally released into the atmosphere through the outdoor heat sink.
When the air conditioning system is in a heat pipe operation mode, high-temperature gaseous heat at the tail end of the air conditioner flows through the air supply pipe 4 to enter the outdoor heat dissipation device, the heat in the pipeline is released by the outdoor heat dissipation device to be converted into liquid refrigerant, then flows through the first outlet of the three-way valve 13 and the liquid supply pipe 1 through the liquid return pipe 5 to enter the tail end of the air conditioner, and at the moment, natural cooling is adopted.
When the air conditioning system is in a cold compensation operation mode, high-temperature gaseous heat at the tail end of the air conditioner flows through the air return pipe 2, flows through the air supply pipe 4, enters the outdoor heat dissipation device, releases heat in a pipeline from the outdoor heat dissipation device, is converted into liquid refrigerant after being cooled, flows through the first outlet and the second outlet of the three-way valve 13 through the liquid return pipe 5, the liquid refrigerant at the first outlet enters the heat exchange unit 16, is liquefied and releases heat, forms low-temperature liquid refrigerant, and flows back to the tail end of the air conditioner, at the moment, only the heat pipe operation mode is adopted for cooling, namely natural cooling is adopted, but the temperature reduction effect is not obvious because the atmospheric environment temperature is high, and the temperature after cooling does not reach the required temperature; therefore, the liquid refrigerant at the second outlet of the three-way valve 13 flows through the flow device 15 to enter the heat exchange unit 16, the heat exchange unit 16 further performs heat exchange, the cooled liquid refrigerant enters the tail end of the air conditioner through the liquid supply pipe 1, meanwhile, the heat exchange unit 16 evaporates and absorbs heat, the gas is low-pressure gas, the compressor 10 operates to compress the low-pressure gas into high-pressure gas, and finally the high-pressure gas is released into the atmosphere through the outdoor heat dissipation device.
Based on above-mentioned technical scheme, the air conditioning system that this application provided includes that the air conditioner is terminal, power cabinet 3 and outdoor heat abstractor 7, and the air conditioner is terminal to communicate through power cabinet 3 with outdoor heat abstractor 7, and power cabinet 3 includes heat transfer unit 16, compressor 10, flow device 15, gas pipeline and liquid pipeline.
