[table 1]
Indoor set machine title Machine class code Capability code
a A0 01
b A1 02
c A2 03

As shown in table 1, for example, be called the indoor set of a for machine name, its classification information is that machine class code is A0, and limit of power information is that capability code is 01, for the indoor set of machine b by name, its classification information is that machine class code is A1, and limit of power information is that capability code is 02.In addition, for the indoor set of machine c by name, its classification information is that machine class code is A2, and limit of power information is that capability code is 03.Higher limit determination section 11, according to these information, judges the condensation endurance of indoor set 3,3a, 3b.And higher limit determination section 11 is by the operating number combination of the power of the condensation endurance of this judgement and indoor set, to revising at the maximum speed of the predefined compressor 4 of off-premises station 2 side., the power of the condensation endurance of higher limit determination section 11 and this judgement correspondingly determines the higher limit (step S2) of the rotating speed of compressor 4.Modification method for the maximum speed (higher limit of rotating speed) of compressor 4 is illustrated in table 2.
[table 2]
As shown in table 2, the maximum speed (higher limit of rotating speed) of compressor 4 adds up to capability code and the fast combination form of indoor set Fan (fan) to be corrected according to indoor set operating number, indoor set.Wherein, indoor set adds up to capability code to refer to the aggregate value of the capability code of the indoor set of real-world operation in all indoor sets that are connected.In addition, as indoor set Fan speed combination form, setting A:Fan speed is only that fast mixing, the C:Fan speed for Hi and M (middle speed) of Hi (at a high speed), B:Fan is only 3 such combination forms of Lo (low speed).In addition, be 1 at the operating number of indoor set, being suitable for A:Fan speed is 3 such combination forms of Lo for Hi, B:Fan are fast for M, C:Fan are fast.
To connect 3 indoor sets at 1 off-premises station, (be respectively indoor set a, indoor set b, indoor set situation c) as example, the correction of the maximum speed to compressor 4 describes.In addition, making the capability code of indoor set a is 01, and making the capability code of indoor set b is 03, and the capability code that makes indoor set c is 04.The indoor set of such specification being connected in the multi-connected air conditioner of off-premises station, at indoor set a be failure to actuate (OFF), when indoor set b and indoor set c action (ON), indoor set adds up to capability code to be 03, and (indoor set b) adds 04, and (indoor set c), is 07.In addition, now, if indoor set b:Hi, indoor set c:M, because the fast combination form of these indoor sets Fan is mixed with Hi and M, therefore, setting Fan speed or passing through the Fan speed that setting (Auto) determines is automatically B.Like this, be 2 at indoor set operating number, it is 07 that running indoor set adds up to capability code, be 06-10, when indoor set Fan speed combination form is B, according to table 2, in the time t from entry into service, the maximum speed of compressor 4 (higher limit of rotating speed) is set to 70Hz.And through after time t, the maximum speed of compressor 4 (higher limit of rotating speed) is changed as 60Hz.Like this, the maximum speed of compressor 4 can be from till starting running to elapsed time t and through after time t, change setting.
Then, under the state of higher limit of rotating speed that has determined compressor 4, as shown in Figure 3, Figure 4, one side communicate by letter each indoor set 3,3a, 3b running ON/OFF state and set Fan speed, one side is carried out the running (step S3) of air conditioner 1.In addition, the indoor set being connected with off-premises station 2 is not limited only to 3, as shown in Figure 3, Figure 4, can be also 4 indoor sets 3,3a, 3b, 3c, also can connect the more indoor set comparing.
And the adjustment part 12 in control part 10, judges whether the rotating speed of compressor 4 is the higher limit (step S4) determining at step S2.In the case of the rotating ratio higher limit of compressor 4 is low, owing to there being the leeway of rise of rotational speed of compressor 4, so, the running ON/OFF state of again simultaneously communicate by letter each indoor set 3,3a, 3b and setting Fan speed, one side is carried out the running (step S4's is no) of air conditioner 1.On the other hand, be higher limit at the rotating speed of compressor 4, enter next step (step S4 is).
Calculate fiducial temperature in next step.The indoor temperature that this fiducial temperature detects according to indoor temperature test section 19 is calculated (step S5).In addition, also can use pre-recorded temperature difference chart, from indicated running by remote controller 23, the setting indoor temperature of indoor set of running and the difference of the temperature of the heat exchanger indoor unit 6 that heat exchanger indoor unit temperature detecting part 20 detects are inferred this fiducial temperature (the step S5a of Fig. 5).Have again, also can calculate as test section 18 (not shown go out) by Hygrothermograph is set.In addition, also can determine fiducial temperature as basis taking the difference of indoor temperature and design temperature.
In next step, whether the temperature of judging the heat exchanger indoor unit 6 that heat exchanger indoor unit temperature detecting part 20 detects in adjustment part 12 is than the fiducial temperature high (step S6) calculating at step S5 or step S5a.In the case of the temperature of heat exchanger indoor unit 6 is lower than fiducial temperature, if wish reduces the temperature of heat exchanger indoor unit 6, encourage the condensation of indoor set 3,3a, 3b, therefore, again one side communicate by letter each indoor set 3,3a, 3b running ON/OFF state and set Fan speed, one side is carried out the running (step S6's is no) of air conditioner 1.On the other hand, in the case of the temperature of heat exchanger indoor unit 6 is higher than fiducial temperature, enter next step (step S6 is).Like this, indoor set 3 and off-premises station 2 as shown in Figure 3, Figure 4, turn round except communicating by letter ON/OFF state and setting Fan speed, the temperature of the heat exchanger indoor unit 6 of also communicating by letter.
Like this, it is the higher limit (step S4 is) determining at step S2 at the rotating speed of compressor 4, and the temperature of heat exchanger indoor unit 6, than in the situation of fiducial temperature high (step S6 is), makes the higher limit rising (step S7) of the rotating speed of compressor 4.And, according to the temperature of heat exchanger indoor unit 6, compressor 4 rotating speeds itself also rise, to approach the temperature (being called target temperature below) (step S8) of the heat exchanger indoor unit 6 as target determining by the operating condition of indoor set 3,3a, 3b.
Like this, the temperature of the heat exchanger indoor unit 6 detecting according to target temperature and heat exchanger indoor unit temperature detecting part 20 poor, determines the ascensional range of the rise of rotational speed that makes compressor 4.If the temperature of heat exchanger indoor unit 6, higher than fiducial temperature, even if make the temperature of heat exchanger indoor unit 6 be reduced to fiducial temperature, also can simultaneously be suppressed at indoor set 3,3a, 3b produce condensation, the further cooling room air of one side.Thus, higher as condition than fiducial temperature taking the temperature of heat exchanger indoor unit 6, make the higher limit of the rotating speed of compressor 4 increase, and make its rotating speed itself also increase.In addition, the design temperature set is high, do not need to improve the refrigerating capacity of air conditioner 1 in the case of the user of air conditioner 1, therefore, return to step S3, remain in operation.
Like this, in step S8, make the rise of rotational speed of compressor 4, with this rotation speed operation compressor 4 (step S9) having risen.And, judge that whether the temperature of heat exchanger indoor unit 6 is than target temperature (becoming the temperature of the heat exchanger indoor unit 6 of target) low (step S10).In the case of the temperature of heat exchanger indoor unit 6 is higher than target temperature, again return to step S9, proceed the running of compressor 4 with the rotating speed having risen, to make the temperature of this heat exchanger indoor unit 6 arrive target temperature (step S10's is no).On the other hand, in the case of the temperature of heat exchanger indoor unit 6 is lower than target temperature, do not need the temperature of heat exchanger indoor unit 6 to reduce, therefore, enter next step (step S10 is)., make the rotating speed decline (step S11) of compressor 4.And, under the state of rotating speed that has reduced compressor 4, return to step S3, again, the running ON/OFF state of simultaneously communicate by letter each indoor set 3,3a, 3b and setting Fan speed, one side continues the running of air conditioner 1.
As explained above, air conditioner 1 in the case of the temperature of heat exchanger indoor unit 6 is higher than fiducial temperature so that the rise of rotational speed of compressor 4 state turn round.Thus, even the not detection means beyond indoor set 3,3a, 3b carry indoor temperature test section 19 and heat exchanger indoor unit temperature detecting part 20, also can detect the indoor set 3 being connected with off-premises station 2, the operating condition of 3a, 3b, be suppressed at the framework condensation of indoor set 3,3a, 3b and water droplet dropped to indoor, and carry out suitable cooling operation, for example, in the scope that does not produce condensation, turn round with the minimum temperature that blows out.The present invention is having connected in the multi-connected air conditioner of various indoor machines, only by indoor temperature test section 19 and heat exchanger indoor unit temperature detecting part 20 are set, just can seek anti-condensationly, therefore, decline and also bring into play effect for the cost of exploitation machine.
