The air-conditioner of the embodiment of the present invention and the control method of air-conditioner are described with reference to the accompanying drawings.
Fig. 1 is the block diagram of the air-conditioner of the embodiment of the present invention.As shown in Figure 1, this air-conditioner comprises: outdoor heat exchanger 1 and indoor heat exchanger 2, multiple switch module 3, load detecting module 4 and control module 5.
Wherein, at least one in outdoor heat exchanger 1 and indoor heat exchanger 2 has multiple independently heat exchange unit 10, and namely say, outdoor heat exchanger 1 and/or indoor heat exchanger 2 have multiple independently heat exchange unit 10, and multiple independently heat exchange unit 10 is arranged with parallel way; Multiple switch module 3 is corresponding with multiple independently heat exchange unit 10 to be arranged; Load detecting module 4 is for detecting the running load of air-conditioner; Control module 5 is for controlling to control the open and close of multiple independently heat exchange unit 10 to the open and close of multiple switch module 3 respectively according to running load.
That is, by carrying out segmentation transformation to outdoor heat exchanger and/or indoor heat exchanger, be divided into multiple heat exchange unit 10, the parallel running of multiple heat exchange unit 10, and multiple heat exchange unit 10 is separate, namely the heat exchange of each heat exchange unit is not all by the impact of other heat exchange units, thus outdoor heat exchanger and/or indoor heat exchanger used different change heat demand, namely meet the demand of different service abilities.In addition, the corresponding switch module of each heat exchange unit, controls the flowing of corresponding heat exchange unit inner refrigerant by the open and close of switch module.Control module 5 can control multiple switch module 3 independently.
In operation of air conditioner process, when running load is less, switch module corresponding to heat exchange unit can be controlled by control module 5 and close to close this heat exchange unit, make the cold-producing medium in this heat exchange unit stop flowing, thus the ability reducing air-conditioner export; When running load is larger, switch module corresponding to heat exchange unit can be controlled by control module 5 and open to open this heat exchange unit, make the flow of refrigerant in this heat exchange unit, thus the ability increasing air-conditioner export.
Thus, the embodiment of the present invention proposes the adjustable air-conditioner of a kind of service ability, adjust between low service ability and high service ability, run under lower service ability when running load is less, run under higher service ability state when environment temperature is higher, thus solve the problem can only run with 72 machines when the service ability of 35 machines just can meet the demands, according to the service ability of practical operation situation adjustment air-conditioner, and promote the comfortableness of air-conditioner, and effectively save electric energy.
In addition, it should be noted that, when air-conditioner runs on refrigeration mode, indoor heat exchanger 2 also can be described as evaporimeter, and multiple heat exchange unit 10 can be multi-stage evaporation pipeline, and outdoor heat exchanger 1 also can be described as condenser, and multiple heat exchange unit 10 can be multistage condenser pipe; When air-conditioner runs on heating mode, indoor heat exchanger 2 also can be described as condenser, and outdoor heat exchanger 1 also can be described as evaporimeter.Wherein, be example in a chiller mode, in operation of air conditioner process, when running load is less, switch module corresponding to pipeline can be evaporated by closedown one section, make the cold-producing medium in this section of evaporation pipeline stop flowing, thus the ability reducing air-conditioner exports in addition, also can close one section of condenser pipe, to keep normal compression ratio, thus ensure the reliability of refrigeration system.
According to a specific embodiment of the present invention, each switch module includes: the first magnetic valve and the second magnetic valve.Wherein, the first magnetic valve can be arranged at the import of corresponding heat exchange unit; Second magnetic valve can be arranged at the outlet of corresponding heat exchange unit.
Particularly, as shown in Figure 2, for indoor heat exchanger 2, there are three independently heat exchange units, three independently heat exchange unit can comprise the first heat exchange unit 11, second heat exchange unit 12 and the 3rd heat exchange unit 13.Wherein, the first magnetic valve 35 and the second magnetic valve 36 of the first magnetic valve 33 that may correspond to of the first magnetic valve 31 that may correspond to of the first heat exchange unit 11 and the second magnetic valve 32, second heat exchange unit 12 and the second magnetic valve the 34, three heat exchange unit 13 correspondence.
Such as, control module 5 can control the first magnetic valve 31 and the second magnetic valve 32 cuts out, control the first magnetic valve 33 and the second magnetic valve 34, first magnetic valve 35 and the second magnetic valve 36 to open simultaneously, thus make the cold-producing medium in the first heat exchange unit 11 stop flowing, make the flow of refrigerant in the second heat exchange unit 12 and the 3rd heat exchange unit 13.
According to one embodiment of present invention, air-conditioner also comprises: multiple air outlet 6.Wherein, multiple air outlet 6 is corresponding with multiple independently heat exchange unit 10, and multiple air outlet 6 is opened simultaneously with corresponding multiple independently heat exchange units 10 or closes.And control module 5 can control multiple air outlet 6 carries out combined type air-supply.
Particularly, as shown in Figure 3, this air-conditioner can comprise three air outlets, and three air outlets can be air outlet 61, air outlet 62 and air outlet 63.Air outlet 61 can, air outlet 62 corresponding with the first heat exchange unit 11 can corresponding and air outlet 63 can be corresponding with the 3rd heat exchange unit 13 with the second heat exchange unit 12.
Such as, close when control module 5 controls the first heat exchange unit 11, control the second heat exchange unit 12 and the 3rd heat exchange unit 13 when opening, the air outlet 61 that control module 5 can control the first heat exchange unit 11 correspondence is simultaneously closed, and the air outlet 63 of the air outlet 62 and the 3rd heat exchange unit 13 correspondence that control the second heat exchange unit 12 correspondence is opened, and namely carries out combined type air-supply from air outlet 62 and air outlet 63.
According to a specific embodiment of the present invention, the running load of air-conditioner is one or more in the personnel amount in the second difference between the first difference between the temperature of room temperature and user's setting, the temperature of user's setting and room temperature, the area in room, air-conditioner place or room.
Specifically, when room area is too narrow and small or the first difference is less or the second difference is less or personnel amount is less, can judge that the running load of air-conditioner is lower, the magnetic valve before and after one section of evaporimeter is closed by one section, the cold-producing medium in this section of evaporimeter is made to stop flowing, close the air outlet that this section of evaporimeter is corresponding, the ability that this reduces air-conditioner exports simultaneously.
For the personnel amount in room, when personnel amount is greater than predetermined number, judge that the running load of air-conditioner is higher, now, need air-conditioner to run under higher service ability, such as, run the demand that could meet user with the service ability of 72 machines; But when personnel amount is less than or equal to predetermined number, judge that the running load of air-conditioner is lower, now, air-conditioner is needed to run under lower service ability, such as run the demand that just can meet user with the service ability of 35 machines or 51 machines, and now just waste electric energy with the operation of the service ability of 72 machines.
According to one embodiment of present invention, when at least one in outdoor heat exchanger 1 and indoor heat exchanger 2 have three independently heat exchange unit and running load be the first difference or the second difference time, if the first difference is greater than the first predetermined threshold value, or, if the second difference is greater than the 3rd predetermined threshold value, then control module 5 control three independently heat exchange unit all open; If the first difference is greater than the second predetermined threshold value and be less than or equal to the first predetermined threshold value, or, if the second difference is greater than the 4th predetermined threshold value and be less than or equal to the 3rd predetermined threshold value, then control module 5 controls three two unlatchings independently in heat exchange unit, and other are closed; If the first difference is less than or equal to the second predetermined threshold value, if or the second difference be less than or equal to the 4th predetermined threshold value, then control module 5 controls three unlatchings independently in heat exchange unit, and other are closed.
Particularly, when air-conditioner runs on refrigeration mode, the temperature T0 deducting user's setting according to the first difference and room temperature T1 controls the open and close of three independently heat exchange units.When air-conditioner runs on heating mode, the temperature T0 according to the second difference and user's setting deducts the open and close that room temperature T1 controls three independently heat exchange units.
According to another embodiment of the invention, control module 5 is also for controlling according to the running frequency of running load to the compressor 7 of air-conditioner.Wherein, if the first difference is greater than the first predetermined threshold value, or if the second difference is greater than the 3rd predetermined threshold value, then control module 5 improves the running frequency of compressor 7; If the first difference is less than or equal to the first predetermined threshold value, if or the second difference be less than or equal to the 3rd predetermined threshold value, then control module 5 reduces the running frequency of compressor 7, thus room temperature is maintained in a more stable value or preset range.
According to the present invention's concrete example, compressor 7 can be frequency-changeable compressor.
Be that difference between the temperature that sets of room temperature and user is as example is to describe the air-conditioner of the embodiment of the present invention in detail below with running load.
When air-conditioner runs on refrigeration mode, if the first difference is greater than the first predetermined threshold value, then control module 5 can control the first magnetic valve 35 and the second magnetic valve 36 is opened, the air outlet 63 simultaneously controlling the 3rd heat exchange unit 13 correspondence is opened, improve the running frequency of compressor 7, and, control module 5 also controls the first magnetic valve 31 and the second magnetic valve 32 and the first magnetic valve 33 and the second magnetic valve 34 and opens, like this, make the first heat exchange unit 11, second heat exchange unit 12 and the 3rd heat exchange unit 13 work simultaneously, thus make air-conditioner run with higher refrigerating capacity when room temperature is higher.
If the first difference is less than or equal to the first predetermined threshold value, then control module 5 can control the first magnetic valve 35 and the second magnetic valve 36 cuts out, and the air outlet 63 simultaneously controlling the 3rd heat exchange unit 13 correspondence is closed, and reduces the running frequency of compressor 7.Judge whether the first difference is greater than the second predetermined threshold value further, if the first difference is greater than the second predetermined threshold value, then control module 5 control first magnetic valve 33 and the second magnetic valve 34 are opened, the air outlet 62 simultaneously controlling heat exchange unit 22 correspondence is opened, and control module 5 also controls the first magnetic valve 31 and the second magnetic valve 32 is opened, like this, the first heat exchange unit 11 and the second heat exchange unit 12 is only made to work, thus make air-conditioner run with lower refrigerating capacity when room temperature is lower, decrease the output of service ability, decrease unnecessary power consumption.
If the first difference is less than or equal to the second predetermined threshold value, control module 5 can control the first magnetic valve 33 again and the second magnetic valve 34 cuts out, the air outlet 62 simultaneously controlling heat exchange unit 22 correspondence is closed, reduce the running frequency of compressor 7, like this, only make the first heat exchange unit 11 work, thus when room temperature is very low, air-conditioner is run with low refrigerating capacity, decrease the output of service ability, decrease unnecessary power consumption.
When air-conditioner runs on heating mode, if the second difference is greater than the 3rd predetermined threshold value, then control module 5 can control the first magnetic valve 31 and the second magnetic valve 32 is opened, the air outlet 61 simultaneously controlling heat exchange unit 21 correspondence is opened, improve the running frequency of compressor 7, and, control module 5 also controls the first magnetic valve 33 and the second magnetic valve 34 and the first magnetic valve 35 and the second magnetic valve 36 and opens, like this, make the first heat exchange unit 11, second heat exchange unit 12 and the 3rd heat exchange unit 13 work simultaneously, thus make air-conditioner run with higher heating capacity when room temperature is lower.
If the second difference is less than or equal to the 3rd predetermined threshold value, then control module 5 can control the first magnetic valve 31 and the second magnetic valve 32 cuts out, and the air outlet 61 simultaneously controlling heat exchange unit 21 correspondence is closed, and reduces the running frequency of compressor 7.Judge whether the second difference is greater than the 4th predetermined threshold value further, if the second difference is greater than the 4th predetermined threshold value, then control module 5 control first magnetic valve 33 and the second magnetic valve 34 are opened, the air outlet 62 simultaneously controlling heat exchange unit 22 correspondence is opened, and control module 5 also controls the first magnetic valve 35 and the second magnetic valve 36 is opened, like this, the second heat exchange unit 12 and the 3rd heat exchange unit 13 is only made to work, thus make air-conditioner run with lower heating capacity when room temperature is higher, decrease the output of service ability, decrease unnecessary power consumption.
If the second difference is less than or equal to the 4th predetermined threshold value, control module 5 can control the first magnetic valve 33 again and the second magnetic valve 34 cuts out, the air outlet 62 simultaneously controlling heat exchange unit 22 correspondence is closed, reduce the running frequency of compressor 7, like this, only make the 3rd heat exchange unit 13 work, thus when room temperature is very high, air-conditioner is run with low heating capacity, decrease the output of service ability, decrease unnecessary power consumption.
Fig. 4 is the flow chart of the control method of air-conditioner according to the embodiment of the present invention.Air-conditioner comprises outdoor heat exchanger and indoor heat exchanger, at least one in outdoor heat exchanger and indoor heat exchanger has multiple independently heat exchange unit, multiple independently heat exchange unit is arranged with parallel way, the multiple switch modules that arrange corresponding to multiple independently heat exchange unit.As shown in Figure 4, the method comprises the following steps:
S1: the running load detecting air-conditioner.
S2: respectively the open and close of multiple switch module are controlled to control the open and close of multiple independently heat exchange unit according to running load.
That is, in operation of air conditioner process, when running load is less, can be closed to close this heat exchange unit by the switch module that control heat exchange unit is corresponding, make the cold-producing medium in this heat exchange unit stop flowing, thus the ability reducing air-conditioner exports; When running load is larger, can be opened to open this heat exchange unit by the switch module that control heat exchange unit is corresponding, make the flow of refrigerant in this heat exchange unit, thus the ability increasing air-conditioner exports.
Thus, the embodiment of the present invention proposes the adjustable air-conditioner of a kind of service ability, adjust between low service ability and high service ability, run under lower service ability when running load is less, run under higher service ability state when environment temperature is higher, thus solve the problem can only run with 72 machines when the service ability of 35 machines just can meet the demands, according to the service ability of practical operation situation adjustment air-conditioner, and promote the comfortableness of air-conditioner, and effectively save electric energy.
In addition, it should be noted that, when air-conditioner runs on refrigeration mode, indoor heat exchanger also can be described as evaporimeter, and multiple heat exchange unit can be multi-stage evaporation pipeline, and outdoor heat exchanger also can be described as condenser, and multiple heat exchange unit can be multistage condenser pipe; When air-conditioner runs on heating mode, indoor heat exchanger also can be described as condenser, and outdoor heat exchanger also can be described as evaporimeter.Wherein, be example in a chiller mode, in operation of air conditioner process, when running load is less, switch module corresponding to pipeline can be evaporated by closedown one section, make the cold-producing medium in this section of evaporation pipeline stop flowing, thus the ability reducing air-conditioner exports in addition, also can close one section of condenser pipe, to keep normal compression ratio, thus ensure the reliability of refrigeration system.

Specifically, when room area is too narrow and small or the first difference is less or the second difference is less or personnel amount is less, can judge that the running load of air-conditioner is lower, the magnetic valve before and after one section of evaporimeter is closed by one section, the cold-producing medium in this section of evaporimeter is made to stop flowing, close the air outlet that this section of evaporimeter is corresponding, the ability that this reduces air-conditioner exports simultaneously.
For the personnel amount in room, when personnel amount is greater than predetermined number, judge that the running load of air-conditioner is higher, now, need air-conditioner to run under higher service ability, such as, run the demand that could meet user with the service ability of 72 machines; But when personnel amount is less than or equal to predetermined number, judge that the running load of air-conditioner is lower, now, air-conditioner is needed to run under lower service ability, such as run the demand that just can meet user with the service ability of 35 machines or 51 machines, and now just waste electric energy with the operation of the service ability of 72 machines.
According to one embodiment of present invention, when at least one in outdoor heat exchanger and indoor heat exchanger have three independently heat exchange unit and running load be the first difference or the second difference time, if the first difference is greater than the first predetermined threshold value, or, if the second difference is greater than the 3rd predetermined threshold value, then control three independently heat exchange unit all open; If the first difference is greater than the second predetermined threshold value and be less than or equal to the first predetermined threshold value, or, if the second difference is greater than the 4th predetermined threshold value and be less than or equal to the 3rd predetermined threshold value, then control three two unlatchings independently in heat exchange unit; If the first difference is less than or equal to the second predetermined threshold value, if or the second difference be less than or equal to the 4th predetermined threshold value, then control three unlatchings independently in heat exchange unit.
Particularly, when air-conditioner runs on refrigeration mode, the temperature T0 deducting user's setting according to the first difference and room temperature T1 controls the open and close of three independently heat exchange units.When air-conditioner runs on heating mode, the temperature T0 according to the second difference and user's setting deducts the open and close that room temperature T1 controls three independently heat exchange units.
According to another embodiment of the invention, the method for the embodiment of the present invention also comprises: control according to the running frequency of running load to the compressor of air-conditioner.Wherein, control specifically to comprise according to the running frequency of running load to the compressor of air-conditioner: if the first difference is greater than the first predetermined threshold value, or, if the second difference is greater than the 3rd predetermined threshold value, then improve the running frequency of compressor; If the first difference is less than or equal to the first predetermined threshold value, if or the second difference be less than or equal to the 3rd predetermined threshold value, then reduce the running frequency of compressor.
Be that difference between the temperature that sets of room temperature and user is as example is to describe the air-conditioner of the embodiment of the present invention in detail below with running load.Particularly, suppose three independently heat exchange unit can comprise the first heat exchange unit, the second heat exchange unit and the 3rd heat exchange unit, as shown in Figure 5, the method for the embodiment of the present invention specifically comprises the following steps:
