Stating first exhaust condenser coil 1a and second exhaust condenser coil 5a can be simultaneously to the cold water in the static submerged coil condenser 2
It is heated, can not only meet the cooling needs to the container-type data center computer room 9, can also be met simultaneously relatively large
Hot water use demand.
Operational mode 2：
The operational mode 2 is divided to for two kinds of situations：
The first situation is that have a small amount of hot water use demands, at this point, first compressor 1 work, the second compressor 5
It closes, the exhaust blower 8 is opened, the first motorized adjustment air-valve 11c, third motorized adjustment air-valve 12d, the second motor-driven valve 16
And third motor-driven valve 17 is opened, the second motorized adjustment air-valve 11d, the 4th motorized adjustment air-valve 12e, the 5th motorized adjustment
Air-valve 12f, the first motor-driven valve 15 and the 4th motor-driven valve 18 are closed；In this case, due to 1 work of the first compressor
Make, the second compressor 5 is closed, and therefore, the first exhaust condenser coil 1a can be to cold in the static submerged coil condenser 2
Water is heated, and the cooling needs to the container-type data center computer room 9 can be not only met, and can also be met simultaneously a small amount of
Hot water use demand；
The second situation is without using hot water, at this point, first compressor 1 works, the second compressor 5 is closed, institute
State the unlatching of exhaust blower 8, the first motorized adjustment air-valve 11c, third motorized adjustment air-valve 12d, the 4th motorized adjustment air-valve
12e, the first motor-driven valve 15 and the 4th motor-driven valve 18 are opened, the second motorized adjustment air-valve 11d, the 5th motorized adjustment air-valve
12f, the second motor-driven valve 16 and third motor-driven valve 17 are closed；In which case it is possible to use cold wind comes after evaporator 4 exchanges heat
Meet the cooling needs of container-type data center computer room 9, and since hot water need not be provided, refrigerant is not into meditation
State submerged coil condenser 2 exchanges heat.
Operational mode 3：First compressor 1 is closed, and the second compressor 5 is opened, and the exhaust blower 8 is closed, and described the
Two motorized adjustment air-valve 11d, the 5th motorized adjustment air-valve 12f, the second motor-driven valve 16 and third motor-driven valve 17 are opened, and described the
One motorized adjustment air-valve 11c, third motorized adjustment air-valve 12d, the 4th motorized adjustment air-valve 12e, the first motor-driven valve 15 and
Four motor-driven valves 18 are closed；In operational mode 3, since first compressor 1 is closed, the second compressor 5 is opened, therefore, institute
The cold water in the static submerged coil condenser 2 can be heated by stating second exhaust condenser coil 5a, in the operational mode 3
Under, it can not only realize and meet the cooling needs to the container-type data center computer room 9 using nature cold wind, it can also be same
When meet a small amount of hot water use demands.
Operational mode 4：First compressor, 1 and second compressor 5 simultaneously closes off, and the exhaust blower 8 is opened, and described the
Two motorized adjustment air-valve 11d and third motorized adjustment air-valve 12d are opened, the first motorized adjustment air-valve 11c, the 4th electric adjustable
Save air-valve 12e, the 5th motorized adjustment air-valve 12f, the first motor-driven valve 15, the second motor-driven valve 16, third motor-driven valve 17 and the 4th
Motor-driven valve 18 is closed, in operational mode 4, since first compressor, 1 and second compressor 5 simultaneously closes off, and, it is suitble to
Hot water need not be being provided, outdoor temperature is relatively low, disclosure satisfy that the cooling needs of the container-type data center computer room 9
In the case of use.
A kind of container-type data center computer-room air conditioning system control method of the present invention, the method need to use the sky
Adjusting system 100, the control method include：
One hot water flow fiducial value of an outdoor temperature fiducial value and setting is set by the control device；
It is and described when the second temperature sensor 14 detects that outdoor temperature is more than or equal to the outdoor temperature fiducial value
When flow gauge 10 detects that the flow of hot water is more than or equal to the hot water flow fiducial value, described in the control device control
First compressor 1, evaporator 4, the second compressor 5 and heat exchanger 7 work at the same time, and control the closing of the exhaust blower 8, control institute
It states the first motorized adjustment air-valve 11c, the 5th motorized adjustment air-valve 12f, the second motor-driven valve 16 and third motor-driven valve 17 to open, control
Make the second motorized adjustment air-valve 11d, third motorized adjustment air-valve 12d, the 4th motorized adjustment air-valve 12e, the first motor-driven valve
15 and the 4th motor-driven valve 18 close；In this case, since outdoor temperature is more than or equal to the outdoor temperature fiducial value of setting,
And the demand of hot water is bigger, it is therefore necessary to while the first compressor 1 and the second compressor 5 are opened, in this way, not only can profit
