Title:
AIR-CONDITIONER
Document Type and Number:
Japanese Patent JP2019020061
Kind Code:
A
Abstract:
To provide an air-conditioner which can perform a suitable defrosting operation according to a frosted amount in an outdoor heat exchanger during heating operation.SOLUTION: When stopping a heating operation and performing a defrosting operation, the CPU210 reads out the number of operation indoor units D and takes in the outdoor air temperature To. Specifically, the CPU210 takes in the temperature detected by an outdoor air temperature sensor 38 via a sensor input part 240, and extract the defrosting operation completion temperature Te with reference to a defrosting operation completion condition table 300 using the number of operation indoor units D and the outdoor air temperature To. Then, the CPU210 starts a defrosting operation, and takes in the outdoor heat-exchanging temperature Tc to compare with the defrosting operation completion temperature Te. If the outdoor heat-exchanging temperature Tc is equal to or more than the defrosting operation completion temperature Te, the defrosting operation stops. Also, if the outdoor heat-exchanging temperature Tc is not equal to or more than the defrosting operation completion temperature Te, the CPU210 continues the defrosting operation.SELECTED DRAWING: Figure 2
