The specific embodiment
To provide the detailed reference of the preferred embodiment of the present invention below, the example is shown in the drawings.
Below, a kind of drive control apparatus and method that is used to have the air-conditioning of a plurality of compressors is described, it can control the refrigerant amount of discharging from condenser according to the driving capacity of compressor, thereby prevents because the driving efficient that the energy consumption increase causes reduces.
Fig. 2 is the block diagram that the drive control apparatus of the air-conditioning that is used to have a plurality of compressors according to the present invention is shown.
As shown in the figure, the drive control apparatus that is used to have the air-conditioning of a plurality of compressors according to the present invention comprises: switch element 100, cold-producing medium collector unit 200 and control module 300.
Switch element 100 is installed in the exit of condensing unit, and switches by control signal, thus the cold-producing medium stream that control is discharged from condensing unit.
More specifically, switch element 100 is installed between condensing unit and the expansion valve, and selects from two streams that the cold-producing medium that condensing unit is discharged will flow through one.
As switch element 100, use the triple valve or the close/open valve that are installed on each stream.
Cold-producing medium collector unit 200 is collected a certain amount of, as to pass through switch element 100 import systems cold-producing medium, thus the refrigerant amount that flows in the minimizing system.
More specifically, when compressor drove with the minimum capacity drive pattern, cold-producing medium collector unit 200 was collected the cold-producing medium of import system too much, thereby the cold-producing medium of aequum is circulated to carry out kind of refrigeration cycle.
Control module 300 detects present load, selects drive pattern based on detected load, and is used for the control signal of gauge tap unit 100 based on selected drive pattern output.
At this, control module 300 detects indoor temperature, and detected indoor temperature and user's preset temperature is compared, thereby detects present load.Perhaps, control module 300 detects outdoor temperature, and detected outdoor temperature and reference temperature are compared, thereby detects present load.
When compressor drove with the heap(ed) capacity drive pattern, control module 300 switched to switch element 100 and stops refrigerant flow direction cold-producing medium collector unit 200, and will import expansion valve from the cold-producing medium that condensing unit is discharged.
On the contrary, when compressor drives with the minimum capacity drive pattern, control module 300 switches to the cold-producing medium of will discharge from condensing unit with switch element 100 and partly is collected in the cold-producing medium collector unit 200, and all the other cold-producing mediums that will not be collected in the cold-producing medium collector unit 200 import expansion valve.
The following explanation with reference to Fig. 3 stated operation.
At first, control module 300 detects when front wheel driving load (SP1), and selects the driven compressor capacity based on detected driving load.
More specifically, when judging when the front wheel driving load is overload, then select the heap(ed) capacity drive pattern.On the contrary, when judge when the front wheel driving load when hanging down load, then select the minimum capacity drive pattern.
For example, when compressor drove with the heap(ed) capacity drive pattern, two compressors drove simultaneously.On the contrary, when compressor drives with the minimum capacity drive pattern, a compressor only being arranged, mainly is a driven compressor that has than low capacity.
Then, control module 300 gauge tap unit 100, with the refrigerant amount (SP3) of discharging from condensing unit according to selected drive pattern control, thus control circulating mass of refrigerant (SP4).
More specifically, when compressor drove with the heap(ed) capacity drive pattern, control module 300 switched to switch element 100 and stops refrigerant flow direction cold-producing medium collector unit 200, and will import expansion valve from the cold-producing medium that condensing unit is discharged.
On the contrary, when compressor drives with the minimum capacity drive pattern, control module 300 switches to the cold-producing medium of will discharge from condensing unit with switch element 100 and partly is collected in the cold-producing medium collector unit 200, and all the other cold-producing mediums that will not be collected in the cold-producing medium collector unit 200 import expansion valve.
As mentioned above, the drive control apparatus at the air-conditioning that is used for having a plurality of compressors according to the present invention is provided with two streams that comprise the cold-producing medium collector unit in the exit of condensing unit.Therefore, the refrigerant amount of discharging from condensing unit according to the driving volume controlled of compressor, thus prevent because cold-producing medium too much causes and drives decrease in efficiency and energy consumption increases.
Because the present invention can be embodied as various ways and not deviate from its spirit or substantive features, so be to be understood that, except as otherwise noted, the foregoing description is not limit by any details of above stated specification, and should in the spirit and scope that the claims of enclosing limit, broadly explain, therefore, falling into all changes in the boundary of claims and the equivalent scope thereof and remodeling all should be the claims of enclosing and contains.
