Air conditioner can stop the identical setting of the timing of (operation of the air-conditioning of each indoor set stops) from controlling via remote controller 50a, the 50b of the outdoor control part 34 of off-premises station 30 or the indoor control part of indoor set, each indoor expansion valve that 50c makes each indoor set with heating starting (the operation of the air-conditioning of each indoor set), heating, therefore can provide an air conditioner to realize the isolated operation of each indoor set, move simultaneously.
Described isolated operation refers to the following running status of air conditioner: by indoor expansion valve is set in each indoor set, can carry out individually indoor expansion valve control, operation start/stop control, heating starting/heating for each of each indoor set and stop control.
Described operation simultaneously refers to the following running status of air conditioner: the indoor expansion valve that carries out individually each indoor set is controlled, but in the whole indoor set being connected with 1 off-premises station, moves start/stop control, heating starting/heating stops control simultaneously.
Then, use Fig. 2 that the transmission of control information of the air conditioner of an embodiment of the invention is described.Fig. 2 is the block diagram of having recorded the transmission of the control information while carrying out above-mentioned isolated operation.Solid arrow represents the transmission of set information and the information of detection, and dotted arrow represents the transmission of control instruction information.
Indoor set 10a, 10b, 10c are provided with: force-feeling sensor 15a, the 15b, the 15c that detect the human action in air-conditioning object space; Detect inlet temperature sensor 14a, 14b, the 14c of inlet temperature; Regulate indoor expansion valve 12a, 12b, 12c and indoor control part 13a, 13b, the 13c of the flow of cold-producing medium; Indoor fan 16a, the 16b, the 16c that for air quantity, control; And shutter 17a, the 17b, the 17c that for wind direction, control.
The outdoor control part 34 that off-premises station 30 arranges compressor 31 and controls the capacity of compressor.Be made as when having connected many indoor sets can isolated operation or move each indoor set simultaneously, and is made as also and can selects its method of operation.
In addition, in indoor, possess design temperature and set remote controller 50a, 50b, the 50c that air quantity is set.Remote controller 50a, 50b, 50c respectively with become right indoor control part 13a, 13b, 13c and be connected, these indoor control parts are connected with outdoor control part 34.Below, the indoor set 10a of take carrys out description operation as representative.
Air conditioner can carry out controlling individually the running status of a plurality of indoor sets, the isolated operation that starts to stop by 1 off-premises station 30.The information starting from the operation of remote controller 50a (for example design temperature, set air quantity), the people that detects by force-feeling sensor 15a /not or the information of people's activity be sent to indoor control part 13a, according to these information, by indoor control part 13a, the design temperature of setting by remote controller 50a and setting air quantity are changed to the information of appropriate design temperature and setting air quantity.The information of this information after changing and the inlet temperature that detected by indoor inlet temperature sensor 14a sends to outdoor control part 34 from indoor control part 13a.Also the transmission of carrying out identical information in other indoor set receives, and information is pooled to outdoor control part 34.
Outdoor control part 34 calculates each the air conditioner load of air-conditioning object space and the air conditioner load of the conditioned space integral body based on these air-conditioning object spaces of each indoor set according to the information receiving from each indoor set.According to this result of calculation, 34 pairs of compressors of outdoor control part 31 carry out volume controlled.In addition, from outdoor control part 34, to indoor control part 13a, send information, make for the mobile refrigerant amount of each indoor set adjustment or adjust the rotating speed of indoor fan 16a, aperture and the wind direction of shutter 17a.And expansion valve 12a makes each indoor set control individually in indoor control part 13a control room, and indoor control part 13a control room internal fan 16a and shutter 17 make to become design temperature after changing and set air quantity.
In the situation that by the driving arrangements such as compressor, indoor fan, shutter successively being moved and control the air conditioner of realizing power saving according to air conditioner load, the information quantitative change between the equipment of formation air conditioner is many, sends the mode receiving and also become complicated.But, according to the present invention, the information of collecting from remote controller 50a, force-feeling sensor 15a, inlet temperature sensor 14a is between indoor control part 13a and outdoor control part 34, to send reception and by the information of outdoor control part 34 computing air conditioner loads, outdoor control part 34 directly or via indoor control part 13a is controlled driving arrangement, therefore in the situation that the situation of 1 indoor set of isolated operation or move many, the control law of air conditioner is all identical, controls and becomes simple.
Thus, outdoor control part 34 calculates the air conditioner load of air-conditioning object space separately and the air conditioner load of the conditioned space integral body based on these air-conditioning object spaces of the indoor set connecting, when compressor 31 being carried out to volume controlled according to this result of calculation, need to not carry out each other the exchange of control information at indoor set.In addition, do not need to send control information with upper control equipment connection and to upper control appliance yet.

When becoming power saving operational mode 1, make the design temperature set by remote controller higher when cooling than common state of a control, low when heating.Meanwhile, make the setting air quantity of indoor fan less than common state of a control.According to the variation of this control method, the power consumption of air conditioner compares with common state of a control the more power saving that becomes.In the present embodiment, in each power saving operational mode, changed design temperature and set air quantity the two, but can be also some.Mainly, as long as realize power saving and make air-conditioning object sky become appropriate environment by jumping to these power saving operational modes.
When being judged as by force-feeling sensor at longer time of the time than jumping to above-mentioned power saving operational mode 1, air conditioner load hour in certain indoor set air-conditioning object space in little, the air-conditioning object space of nobody or people's activity, this indoor control part is controlled, and makes the indoor set of this air-conditioning object space jump to individually power saving operational mode 2.
When having become power saving operational mode 2, make the design temperature set by remote controller higher when cooling than power saving operational mode 1, low when heating.Meanwhile, the setting air quantity of indoor fan is made as identical with power saving operational mode 1 or less.According to the variation of this control method, the power consumption of air conditioner is compared more power saving with power saving operational mode 1.
When being judged as by force-feeling sensor at longer time of the time than jumping to above-mentioned power saving operational mode 2, air conditioner load hour in certain indoor set air-conditioning object space in little, the air-conditioning object space of nobody or people's activity, this indoor control part is controlled, and makes the indoor set of this air-conditioning object space jump to individually power saving operational mode 3.
When becoming power saving operational mode 3, this indoor set is made as heating to be stopped, and stops fan, and the air quantity of indoor fan is made as to 0.According to the variation of this control method, the power consumption of air conditioner is compared more power saving with power saving operational mode 2.
In addition, under the condition as power saving operational mode 3, also consider by force-feeling sensor judge for people not quite long state of time, exist and to forget the possibility of turning off indoor unit.Thus, when become as power saving operational mode 3 condition time, also can make indoor set out of service individually.
From described power saving operational mode 1, power saving operational mode 2, power saving operational mode 3, by described force-feeling sensor, be judged as and in each room conditioning object space, have people or activity large in the situation that, this indoor control part is controlled, and makes the indoor set of this air-conditioning object space jump to common control.
