Control device for air-conditioning equipment and air conditioning system

Abstract

A control device for air-conditioning equipment includes: an acquirer that acquires information relevant to occurrence of condensation on a surface of a door of a showcase having a storage in which a product stored therein is refrigerated, the storage having an opening that is opened and closed with the door; and a controller that causes an adjuster that adjusts a direction of cool air output from the air-conditioning equipment to direct the cool air to the showcase, upon determining that a possibility that condensation occurs on the surface of the door has increased, based on the information acquired by the acquirer.

What is claimed is: 
     
         1 . A control device for air-conditioning equipment, the control device comprising:
 an acquirer that acquires information relevant to occurrence of condensation on a surface of a door of a showcase having a storage in which a product stored therein is refrigerated, the storage having an opening that is opened and closed with the door; and   a controller that causes an adjuster that adjusts a direction of cool air output from the air-conditioning equipment to direct the cool air to the showcase, upon determining that a possibility that condensation occurs on the surface of the door has increased, based on the information acquired by the acquirer.   
     
     
         2 . The control device according to  claim 1 ,
 wherein, upon causing the adjuster to direct the cool air to the showcase, the controller increases a cooling output of the air-conditioning equipment.   
     
     
         3 . The control device according to  claim 2 ,
 wherein the controller increases a cooling output of the air-conditioning equipment, as the condensation occurrence possibility indicated by the information acquired by the acquirer increases.   
     
     
         4 . The control device according to  claim 3 ,
 wherein the controller reduces a temperature of the cool air output from the air-conditioning equipment, as the condensation occurrence possibility indicated by the information acquired by the acquirer increases.   
     
     
         5 . The control device according to  claim 3 ,
 wherein the controller increases a volume of the cool air output from the air-conditioning equipment, as the condensation occurrence possibility indicated by the information acquired by the acquirer increases.   
     
     
         6 . The control device according to  claim 1 ,
 wherein, upon determining that a possibility that condensation occurs on the surface of the door of the showcase has decreased, based on the information acquired by the acquirer, the controller deactivates the control for causing the adjuster to direct the cool air to the showcase.   
     
     
         7 . The control device according to  claim 1 ,
 wherein the information indicates a relative humidity of air outside the door of the showcase.   
     
     
         8 . The control device according to  claim 1 ,
 wherein the information indicates a temperature difference between a surface temperature of the door of the showcase and a temperature of air outside the door of the showcase.   
     
     
         9 . An air conditioning system comprising:
 air-conditioning equipment; and   the control device according to  claim 1 .
