Refrigeration cycle apparatus

Abstract

Provided is a refrigeration cycle apparatus, in which, when refrigerant is detected by a refrigerant detector, an informing unit informs of occurrence of leakage of the refrigerant and countermeasure information for enabling determination of a procedure of coping with the refrigerant leakage.

1 . A refrigeration cycle apparatus, comprising:
 an indoor unit including:
 a load-side heat exchanger forming a refrigeration cycle, through which refrigerant is circulated; 
 a refrigerant detector configured to detect the refrigerant; and 
 an air-sending fan, 
 the indoor unit being installed indoors; 
   a controller configured to control the indoor unit;   an informing unit configured to present information about the refrigerant; and   a timer configured to measure time,   wherein the controller is configured to, when the refrigerant is detected by the refrigerant detector, control the informing unit to present, as countermeasure information for enabling determination of a procedure of coping with refrigerant leakage, information about the elapsed time measured by the timer, or a remaining time to a preset predetermined time.   
     
     
         2 . The refrigeration cycle apparatus of  claim 1 , wherein the controller is configured to, when the refrigerant is detected by the refrigerant detector, first bring the air-sending fan into an operation state and then start the timer. 
     
     
         3 . The refrigeration cycle apparatus of  claim 1 , wherein the controller is configured to, when the refrigerant is detected by the refrigerant detector, first start the timer and then bring the air-sending fan into an operation state. 
     
     
         4 . The refrigeration cycle apparatus of  claim 1 , wherein the controller is configured to control the informing unit to present information representing occurrence of the refrigerant leakage. 
     
     
         5 . The refrigeration cycle apparatus of  claim 1 , wherein the controller is configured to, when the refrigerant is detected by the refrigerant detector, bring the air-sending fan into an operation state. 
     
     
         6 . The refrigeration cycle apparatus of  claim 1 , wherein the informing unit is provided on a design surface of a casing of the indoor unit. 
     
     
         7 . The refrigeration cycle apparatus of  claim 1 , wherein the informing unit includes a display device to be additionally connected to the indoor unit. 
     
     
         8 . The refrigeration cycle apparatus of  claim 1 , wherein the indoor unit includes a battery. 
     
     
         9 . The refrigeration cycle apparatus of  claim 1 , wherein the controller is configured to, when a preset time elapses after the refrigerant is detected by the refrigerant detector, stop the air-sending fan.
