  • an air conditioner is an appliance for cooling and heating an indoor space, such as a residential interior space, a restaurant or an office.
  • an indoor space such as a residential interior space, a restaurant or an office.
  • multiple type air conditioners which can cool and heat respective rooms independently have been developed.
  • a multiple type air conditioner is configured in such a manner that a plurality of indoor units are connected to a single outdoor unit, and the indoor units are installed in respective rooms.
  • Each indoor unit operates in either a cooling mode or a heating mode, and conditions air of an indoor space.
  • EP 1 526 341 discloses a multi-unit type air conditioner which may operate in a cooling major mode or in a heating major mode.
  • the invention therefore provides a simultaneous cooling-heating multiple type air conditioner as set out in claim 1.
  • Examples provide a simultaneous cooling-heating multiple type air conditioner including a plurality of cooling-heating combined-use indoor units, each having an indoor heat exchanger, a cooling-heating combined-use outdoor unit including a compressor, an outdoor heat exchanger, and a refrigerant switching part installed at a discharge side of the compressor for switching flow of refrigerant based on operation conditions such as cooling-only operation, heating-only operation, cooling-initiative simultaneous cooling and heating operation, and heating-initiative simultaneous cooling and heating operation, and a distributor installed between the cooling-heating combined-use indoor units and the cooling-heating combined-use outdoor unit for distributing the refrigerant into passages of the cooling-heating combined-use indoor units based on the operation conditions such as cooling-only operation, heating-only operation, cooling-initiative simultaneous cooling and heating operation, and heating-initiative simultaneous cooling and heating operation, wherein the air conditioner is controlled with an operation domain including a plurality of operation zones which are divided according to a refrigerant suction pressure and a refrigerant discharge pressure of the compressor, in
  • the suction pressure of the compressor is less than a first suction pressure
  • a discharge pressure of the compressor is less than a first discharge pressure
  • the suction pressure of the compressor ranges from the first suction pressure to a second suction pressure wherein the second suction pressure is greater than the first suction pressure and the discharge pressure of the compressor ranges from the first discharge pressure to a second discharge pressure wherein the second discharge pressure is greater than the first discharge pressure
  • the suction pressure of the compressor is greater than the second suction pressure and the discharge pressure of the compressor is greater than the second discharge pressure.
  • the air conditioner operating in the first operation zone and the third operation zone can be controlled to move to the second operation zone by varying discharge flow rate of refrigerant discharged from the compressor or the number of revolutions of the outdoor fan.
  • the distributor may include a liquid header, a low pressure gas header, and a high pressure gas header.
  • the simultaneous cooling-heating multi-air conditioner according to the present invention may further include a liquid refrigerant pipe for connecting the cooling-heating outdoor unit to the liquid header, a low pressure gas pipe for connecting the cooling-heating outdoor unit to the low pressure gas header, and a high pressure gas pipe for connecting the cooling-heating outdoor unit to the high pressure gas header.
  • the simultaneous cooling-heating multiple type air conditioner switches its operation modes in an operation domain divided into a plurality of operation zones based on the refrigerant suction pressure and the refrigerant discharge pressure of the compressor, it can be steadily operated and controlled during the simultaneous cooling and heating operation period.
  • a multiple type air conditioner in which some indoor units operate to cool air and the other indoor units operate to heat air at the same time has been researched and developed.
