- control may be performed so that each adjacent machine 130f to l 30h, 130m, 130p, and so on;
- the boundary corresponding to the adjacent machine 130f to 30h, 130m, 130p to l 30r in order to prevent the adjacent machine 130f to 130h, 130m, 130p, and 130r from operating as selected by the user.
- the side space N1 there is a risk that comfort may be impaired due to high temperatures. Therefore, in this modification, when the operating units 130k and 1301 perform the cooling operation, the air volume of the adjacent units 130f to 130h, 130m, 130p to 130r is increased. That is, in this modification, the airflow in the boundary side space N1 is promoted, and the difference in the temperature of the sensation between the boundary side space N1 and the inner space N2 is reduced, so that the above problem is solved. .
- the adjacent machine 130f ⁇ ; 130h, 130m, 130p ⁇ ; 130r force S, the boundary side space N1 where it is installed, and the cell space Ta ⁇ Te, Ti, Tj, Tn, Since the temperature difference between To, Ts, Tt, and Tu ⁇ Ty is not so large, the diffusion of cold air from the space N is suppressed.
- each adjacent machine 130f ⁇ ; 130h, 130m, 13 Op ⁇ ; 130r may be controlled by the adjacent machine control unit 114 so that the difference between the two is less than a predetermined value.
- the body If the temperature difference cannot be kept below the specified value, increase the capacity of the operating units 130k, 1301, the adjacent units 130f ⁇ ; 130h, 130m, 130p ⁇ ; 130r, or both. Such control may be performed.
- the difference in sensory temperature is the user's preference for the output value and draft feeling of the suction temperature sensor installed near the suction port 33 of the adjacent machine 130f ⁇ 130h, 130m, 130p ⁇ ; 130r and the driver 130k, 1301. It can be indexed based on information about etc. Further, instead of the difference in temperature of the sensation, the comfort of the boundary side space Nl (cell spaces Tf to Th, Tm, Tp to Tr) may be indexed and measured. Note that ⁇ ⁇ appropriate life means each adjacent machine 130f ⁇ ; 130h, 130m, 130p ⁇ ; 130r suction V, suction suction attached near the inlet 33, and the output value and draft feeling of the inlet temperature sensor It can be indexed based on information about user preferences, etc.
- the driver control unit 113 determines the direction of the air flow from each driver 130k, 13C ⁇ . Adjacent machine 130f ⁇ ; 13 Oh, 130m, 130p ⁇ ; In this case, the wind directions of the respective drivers 130k and 1301 are almost horizontal, and an airflow is formed over the ceiling near the ceiling of the space N. This makes it easy for the cool air that tends to accumulate downward to accumulate near the ceiling of space N, and the cold air blown from the driver 130k, 13 ( ⁇ does not immediately diffuse near the floor of space N. Since the cool air accumulated in the vicinity gradually diffuses toward the floor over time, in this modification, the entire space N can be uniformly cooled.
- each of the indoor units 130a, 130b,..., 130y flaps 31a to 31d can be opened and closed independently as in the modification (3).
- the air currents from the flaps 31a to 31d of the respective operating units 130k and 1301 are controlled so as not to collide with each other.
- Cool air power Neighboring machine 130f ⁇ ; 130h, 130m, 130p ⁇ ; 130r force, etc. Will be formed.
- the entire space N can be uniformly cooled.
- the adjacent machines 130f ⁇ ; 130h, 130m, 130p ⁇ ; 130ri are controlled by the adjacent machine control unit 114 as follows! That is, the adjacent machine control unit 114 stops and sucks air from the flaps close to the operating machines 130k and 1301 among the respective flaps 31a to 31d of the adjacent machines 130f to 130h, 130m, and 130p to 130r. Air is blown out only from the flap farther from the inner space N2 than the mouth 33.
- each adjacent machine 130f ⁇ 130h, 130m, 130p ⁇ ; 130r (or the operating machine 130k, 1301 force, etc.) can be easily sucked in through the suction inlet 33, and the cold air can be sucked into the adjacent machine 130f.
- the adjacent device control unit 114 performs the difference in the sensible temperature and the boundary side between the boundary side space N1 and the inner space N2. Comfort in space N 1 ⁇ ⁇ Based on this, each adjacent machine 130f ⁇ ; 130h, 130m, 130p ⁇ ; Can of 130r wind direction and air volume IJ P can be fi. Therefore, it is also possible to form a swirling airflow in the space N while directing the air blown by the adjacent machine 130f ⁇ ; 130h, 130m, 130p ⁇ ; 130r force to the living body in the boundary side space N1.
- the air conditioning control device 101 may be a central remote controller for the air conditioner including the indoor units 130a, 130b,..., 130y. Therefore, the user can also input an operation command for each of the indoor units 130a, 130b,..., 130y via an input unit (not shown) of the air conditioning control device 101.
- the operation command input via the input unit (not shown) of the air conditioning control device 101 is processed in the same manner as the operation command input via the remote controllers 40a, 40b,..., 40y.
- the present invention improves the air-conditioning operation efficiency in the part of the space, thereby saving energy.
- the air conditioning system installed in one space It is useful as an air-conditioning control device and control method that collectively control the operation of a group of indoor units consisting of several indoor units.
