Abstract:
Provided is a refrigeration apparatus in which a decrease in a temperature of an indoor heat exchanger can be suppressed as much as possible while depletion of refrigerator oil in a compressor is also suppressed. An air-conditioning apparatus configured from a parallel connection of a plurality of outdoor units to an indoor unit, wherein when a predetermined defrosting condition has been fulfilled, a controller includes at least one processor programmed to selectively execute a reverse-cycle defrost mode when a predetermined outflow condition pertaining to an outflow integrated quantity of refrigerator oil has also been fulfilled, and selectively execute an alternating defrost mode, in which the outdoor unit that is to be defrosted is changed in sequence, when the predetermined outflow condition has not been fulfilled.

Claim (Index 1):
A refrigeration apparatus configured from a parallel connection of a plurality of outdoor units to an indoor unit, the refrigeration apparatus comprising:\n a refrigerant circuit capable of executing at least an air-warming operation and configured from a connection of:\n an indoor heat exchanger provided to the indoor unit; and \n outdoor heat exchangers, compressors, and switching valves provided to the respective outdoor units; and \n a controller including at least one processor programmed to selectively execute one of the following when a predetermined defrosting condition is fulfilled during execution of the air-warming operation:\n an alternating defrost mode in which an operation, which is performed with the switching valves having been connected such that at least one of the outdoor heat exchangers of the plurality of outdoor units is caused to function as evaporator while one or more outdoor heat exchangers of the rest of the plurality of outdoor units is caused to function as condenser by being designated as component to be defrosted, is executed while switching the outdoor heat exchanger to be defrosted; and \n a reverse-cycle defrost mode executed with the switching valves having been connected such that the outdoor heat exchangers of the outdoor units are caused to function as condensers and the indoor heat exchanger is caused to function as an evaporator, \n wherein the at least one processor is further programmed to, when the predetermined defrosting condition having been fulfilled, selectively execute the reverse-cycle defrost mode when a predetermined outflow condition pertaining to an outflow integrated quantity of refrigerator oil has also been fulfilled and selectively executing the alternating defrost mode when the predetermined outflow condition has not been fulfilled.
