Air conditioner

Abstract

An air conditioner that performs an air conditioning operation in an indoor space includes a compressor and a controller that controls an operating frequency of the compressor at a predetermined update interval in accordance with an air conditioning load in the indoor space. The controller shortens the update interval when a first condition indicating that the air conditioning load is low and a second condition indicating that a performance of the compressor to the air conditioning load is high are satisfied.

What is claimed is: 
     
         1 . An air conditioner that performs an air conditioning operation in an indoor space, the air conditioner comprising:
 a compressor;   a controller that controls an operating frequency of the compressor at a predetermined update interval in accordance with an air conditioning load in the indoor space, wherein
 the controller shortens the update interval when a first condition indicating that the air conditioning load is low and a second condition indicating that a performance of the compressor is high with respect to the air conditioning load are satisfied. 
   
     
     
         2 . The air conditioner according to  claim 1 , wherein the first condition includes that a difference between an indoor temperature and a target indoor temperature is equal to or less than a first threshold. 
     
     
         3 . The air conditioner according to  claim 1 , wherein the second condition includes that a change amount per unit time of a difference between an indoor temperature and a target indoor temperature is equal to or less than a second threshold (where the second threshold<0). 
     
     
         4 . The air conditioner according to  claim 1 , wherein
 the second condition includes that a change amount per unit time of a difference between an indoor temperature and a target indoor temperature is equal to or less than a second threshold (where the second threshold<0), and   the first condition includes that, after the second condition is satisfied, the difference is estimated to be less than or equal to a first threshold within a predetermined time on a basis of the change amount.   
     
     
         5 . The air conditioner according to  claim 1 , wherein the controller maintains a state in which the update interval is shortened until the first condition is released after the first condition and the second condition are satisfied. 
     
     
         6 . The air conditioner according to  claim 5 , wherein the controller extends the update interval when a predetermined third condition set in advance is further satisfied after the first condition is released. 
     
     
         7 . The air conditioner according to  claim 6 , wherein the third condition includes that a predetermined time elapses. 
     
     
         8 . The air conditioner according to  claim 6 , wherein the third condition includes that the difference exceeds a third threshold higher than the first threshold.
