Title:
AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2022/201738
Kind Code:
A1
Abstract:
This air conditioner comprises an outdoor unit, an indoor unit, a refrigerant cut-off unit, an airtight state detection unit, a notification unit, and a control unit. The refrigerant cut-off unit cuts off or reinstates the flow of refrigerant flowing into the indoor unit and the flow of refrigerant flowing out from the indoor unit. The airtight state detection unit detects an airtight state of piping in the indoor unit. The notification unit issues notification of the results of detection by the airtight state detection unit. The control unit assesses a refrigerant cut-off condition indicating whether the flows of refrigerant flowing into and out from the indoor unit are to be cut off. When the refrigerant cut-off condition is satisfied, the control unit causes the refrigerant cut-off unit to cut off the flows and causes the notification unit to issue notification of the result of detection of the airtight state of the piping as detected by the airtight state detection unit in the indoor unit for which the flows of refrigerant are cut off.
