Air-conditioning controller and air-conditioning apparatus

Abstract

An air-conditioning controller configured to control an air-conditioning apparatus includes: an environmental-state-quantity acquisition unit; an occupant-information acquisition unit; a temperature-preference input unit; a storage unit configured to store the quantity of environmental state at a point in time when comfort information is acquired, occupant information, and the comfort information such that the quantity of environmental state at the point in time, the occupant information, and the comfort information are associated with each other; a comfort calculation unit; and a set-value calculation unit configured to calculate a set value to the air-conditioning apparatus based on a calculated comfort range such that a maximum in number of occupants of a plurality of occupants are satisfied with the state of the air-conditioning target space.

1 . An air-conditioning controller configured to control an air-conditioning apparatus, the air-conditioning controller comprising a processor and a memory, the processor being configured to:
 acquire a quantity of environmental state that indicates a state of an air-conditioning target space;   acquire occupant information that specifies a plurality of occupants present in the air-conditioning target space; and   acquire comfort information that is input by the plurality of occupants and indicates a warm-cold sense of each of the plurality of occupants to the air-conditioning target space;   the memory being configured to store the quantity of environmental state at a point in time when the comfort information is acquired, the occupant information, and the comfort information such that the quantity of environmental state at the point in time, the occupant information, and the comfort information are associated with each other;   the processor being configured to   calculate a comfort range for each of the plurality of occupants based on the quantity of environmental state at the point in time, the occupant information, and the comfort information that are associated with each other and stored in the memory; and   calculate a set value to the air-conditioning apparatus based on the calculated comfort range such that a maximum in number of occupants of the plurality of occupants are satisfied with the state of the air-conditioning target space.   
     
     
         2 . The air-conditioning controller of  claim 1 , wherein the processor is configured to
 define, as the comfort range, a range of a quantity of environmental state between a maximum value of the quantity of environmental state when the occupant feels cold and a minimum value of the quantity of environmental state when the occupant feels hot.   
     
     
         3 . The air-conditioning controller of  claim 1 , wherein the processor is configured to
 set, as an optimum set value, the set value that causes a number of the comfort ranges for the plurality of occupants within which the set value falls to be maximized.   
     
     
         4 . The air-conditioning controller of  claim 3 , wherein the processor is configured to,
 when there are a plurality of the optimum set values, define one of the optimum set values, at which the air-conditioning apparatus achieves lowest power consumption, as the optimum set value.   
     
     
         5 . The air-conditioning controller of  claim 1 , wherein
 the air-conditioning target space is divided into a plurality of zones, and one or a plurality of the air-conditioning apparatuses are located to condition air in each of the divided zones, and   wherein the process is further configured to:   calculate a destination to which the occupant moves from the zone where the occupant is present based on the comfort information and the set value to each of the zones; and   instruct the occupant to move from the zone based on a result of calculating destination.   
     
     
         6 . The air-conditioning controller of  claim 5 , wherein
 the processor is configured to   set, as an optimum set value, the set value that causes a number of the comfort ranges for the plurality of occupants within which the set value falls to be maximized,   specify the occupant for which the optimum set value to the current zone does not fall within the comfort range as an occupant having a low degree of satisfaction with a heat environment of the current zone,   search for a zone where the optimum set value falls within the comfort range for the specified occupant, and   determine the zone that is searched out as a destination zone.   
     
     
         7 . An air-conditioning apparatus comprising the air-conditioning controller of  claim 1 .
