Abstract
An air conditioner of the present disclosure includes one or more outdoor units comprising a compressor and an outdoor heat exchanger which exchanges heat between a refrigerant flowing through the compressor and external air; and a plurality of indoor units which are connected to the outdoor unit, and have an indoor heat exchanger, wherein the plurality of indoor units include a first indoor unit group and a second indoor unit group, wherein the outdoor unit and the first indoor unit group are connected by a first gas pipe and a liquid pipe, and wherein the outdoor unit and the second indoor unit group are connected by a second gas pipe and the liquid pipe.
Claims12
An air conditioner, comprising:
- one or more outdoor units comprising a compressor and an outdoor heat exchanger that exchanges heat between a refrigerant flowing through the compressor and external air;
- a plurality of indoor units that is connected to the one or more outdoor units and has an indoor heat exchanger, wherein the plurality of indoor units comprises a first indoor unit group and a second indoor unit group, wherein the one or more outdoor units and the first indoor unit group are connected by a first gas pipe and a liquid pipe, and wherein the one or more outdoor units and the second indoor unit group are connected by a second gas pipe and the liquid pipe;
- and
- a first switching valve that switches the outdoor heat exchanger to a condenser or an evaporator;
- and
- a second switching valve that switches the second gas pipe into a high-pressure pipe or a low-pressure pipe, wherein when the first indoor unit group performs a heating operation and the second indoor unit group performs a cooling operation, if a heating load of the first indoor unit group is larger than a cooling load of the second indoor unit group, the first switching valve is turned on, and the outdoor heat exchanger is used as an evaporator.
An air conditioner, comprising:
- one or more outdoor units comprising a compressor and an outdoor heat exchanger that exchanges heat between a refrigerant flowing through the compressor and external air;
- a plurality of indoor units that is connected to the one or more outdoor units, and have an indoor heat exchanger, wherein the plurality of indoor units comprises a first indoor unit group comprised of a dedicated heating indoor unit and a second indoor unit group comprised of an indoor unit for both heating and cooling, wherein the one or more outdoor units and the first indoor unit group are connected by a first gas pipe and a liquid pipe, wherein the one or more outdoor units and the second indoor unit group are connected by a second gas pipe and the liquid pipe;
- and
- a first switching valve that switches the outdoor heat exchanger to a condenser or an evaporator;
- and
- a second switching valve that switches the second gas pipe into a high-pressure pipe or a low-pressure pipe, wherein when the first indoor unit group performs a heating operation and the second indoor unit group performs a cooling operation, if a heating load of the first indoor unit group is larger than a cooling load of the second indoor unit group, the first switching valve is turned on, and the outdoor heat exchanger is used as an evaporator.
