Control device 7 is connect with detection device 8, two pumps 4 and two 3 signals of compressor respectively, and according to receiving
The comparison result of parameter and given threshold, selectively controls two pumps 4 and two compressors 3 are run.
In the above-described embodiments, it is run, is filled by selectively controlling the various combination of two pumps 4 and two compressors 3
Divide using 4 low operation energy consumption features of outdoor cold source and pump, significantly reduces air-conditioning while realizing heat source refrigeration demand
Operation consumption.
Wherein, parameter is outdoor temperature or condensing pressure.Can be achieved detect the parameter when, can according to the parameter with set
The comparison result of threshold value is determined to control the operation of air-conditioning.Understanding to air-conditioning provided in this embodiment for convenience, below with room
Outer temperature is as a parameter to be described, it should be appreciated that described below is only the specific embodiment enumerated, and is not used to
The limitation present invention.

When the outdoor detection temperature received is less than the second set temperature, two pumps, 4 operation is controlled.
Different control models can be selected according to the actual situation in above-mentioned three kinds of control modes, i.e., can both be separately provided
Perhaps pump+compressor control model or any combination are above-mentioned for the mode that the mode of two pump operations, two compressors are run
Control model, i.e. can be set in an air-conditioning system operational mode there are two pump operation mode and two compressors or
The different control model of two pump operation modes and pump+compressor mode etc. is arranged in person, and user can make according to actual
The selection of mode is carried out with situation.
Understanding to above-mentioned specific embodiment for convenience, is with reference to the accompanying drawing described in detail it.
Temperature outside by sensing chamber, i.e. ambient temperature, and adjusted by ambient temperature as decision condition
The operational mode of whole air-conditioning, in order to realize supply air temperature control, the refrigerating capacity under Three models must reach the nominal cooling capacity of unit.
As shown in Fig. 2, two cooling devices are respectively A and B, each cooling device includes pump 4 and compressor 3, due to pumping system
Efficiency is much higher than compressor assembly, therefore the control thinking of unit is that preferential open pumps 4, is run with pumping system, is unsatisfactory for wanting in pump 4
In the case where asking, it is then turned on compressor 3, is run with compressor assembly.When the refrigerating capacity of pumping system reaches the water of compressor assembly
Flat, pump 4 replaces compressor 3 completely, and unit enters 4 mode of double pump, and two cooling devices open pump 4；When the refrigerating capacity ratio of pump 4
3 refrigerating capacity of compressor is small, and this small part refrigerating capacity can be by the compressor 3 of another cooling device come when compensating, then machine
Group enters 4 modes of the mono- pump of single compressor 3+, i.e. a cooling device opens compressor 3, another cooling device opens pump 4, this
When, it pumps as capacity operation；When pumping 4 this part refrigerating capacitys smaller than compressor 3, the compressor 3 of another cooling device is
It can not be fully compensated, then enter 3 mode of double-compressor, two cooling devices open compressor 3.
Due to the raising with outside air temperature, the cooling capacity that pumping system is capable of providing is gradually reduced, and compressor assembly is cold
Amount is basically unchanged.Therefore in order to accurately control supply air temperature, the condition that double pump 4 is opened is the refrigerating capacity that pumping system is capable of providing
Reach the refrigerating capacity of compressor assembly.I.e. as shown in Figure 3, Fig. 3 shows the control flow of air-conditioning provided in this embodiment,

Using frequency-changeable compressor or digital scroll compressor, capacity is adjustable, maximum cooling capacity it is more general than nominal cooling capacity it is big by 20%~
30%；With the raising of outdoor temperature, cooling capacity constantly decaying pumping system, when the refrigerating amount attenuation of pump 4 is to the 70% of compressor 3
~80%, i.e., 1 compressor 3 and 1 pump 4 need to be opened, the insufficient cooling capacity of pumping system is compensated by compressor assembly, and system enters
Single compressor 3+ 4 modes of mono- pump, i.e. a cooling device are run with compressor mode, another cooling device is to pump mode fortune
Row.When the refrigerating capacity for pumping 4 is lower than the 70% of 3 ability of compressor, in order to accurately control supply air temperature, pump 4 cannot be then turned on.I.e.
As shown in Figure 3, as outdoor temperature T > M, system enters 3 mode of double-compressor, and two sets of cooling devices are with 3 mode of compressor
Operation, the value interval of M is (- 5,20), and the value of M need to be greater than the value of N.Preferably, 4 modes of the mono- pump of single compressor 3+
Temperature range of operation is (0,10).In above-mentioned specific control mode, it should be appreciated that the specific control under different mode
Mode, which can according to need, to be selected, selection as it is above-mentioned different modes is set within air-conditioning systems, both can be with
It is used alone, can also arbitrarily be combined to use.

Control device 7 is connect with temperature-detecting device signal, and is greater than the first setting temperature in received outdoor detection temperature T
M is spent, two compressors 3 is controlled and runs, or control two pumps less than the second set temperature N in the outdoor detection temperature T received
When 4 operation, when the supply air temperature of detection is more than or equal to the first setting supply air temperature and is less than or equal to the second setting supply air temperature, control
System pump 4 or compressor 3 keep former power output, detection supply air temperature be greater than second setting supply air temperature when, control pump 4 or
Compressor 3 increases output power；When the supply air temperature of detection is less than the first setting supply air temperature, control pump 4 or compressor 3 drop
Low output power.It is described in detail with reference to the accompanying drawing in order to facilitate description.
