Definitions

  • the present disclosure relates to an air conditioning system and a control method for the air conditioning system, and more particularly, to an air conditioning system having improved air conditioning efficiency and a control method for the air conditioning system.
  • US 2004/0144111 A1 relates to an air conditioning system provided with an outdoor unit having a compressor and an outdoor heat exchanger, an indoor unit having an indoor heat exchanger, and a gaseous refrigerant pipe connecting the indoor heat exchanger to the compressor.
  • the air conditioning system is provided with one air-cooled outdoor unit and a plurality of indoor units connected parallel to the outdoor unit.
  • the indoor heat exchangers and the compressor are connected together by the gaseous refrigerant pipe.
  • a pressure adjusting device is installed in the gaseous refrigerant pipe.
  • the pressure adjusting device is a single integral unit equipped with a pressure detecting means, an electric powered expansion valve, and an opening adjusting means and functions to adjust the pressure in the indoor heat exchanger to a higher pressure then the pressure in the indoor heat exchangers of the other indoor units.
  • GB 2 248 494 A discloses du air Conditioning System according to the preamble of claim 1.
  • Some air conditioning systems have one or more outdoor units and a plurality of indoor units. Such air conditioning systems are called as multiple air conditioning systems.

In the series type air conditioning system, a plurality of outdoor units are connected to a plurality of indoor units.
  • the multiple air conditioning systems can also be classified into switching type air conditioning systems and mutli-mode air conditioning systems according to refrigerant circulating methods. In the switching type air conditioning system, all indoor units simultaneously switch between cooling mode and heating mode.

Therefore, it is difficult to match heating/cooling load on the indoor units with heating/cooling load on the outdoor units. That is, in the multi-mode air conditioning system, an excessive amount of refrigerant can be supplied to an indoor unit while an insufficient amount of refrigerant is supplied to another indoor unit. As a result, the refrigerant cycle of the multi-mode air conditioning system can become unstable, and thus the efficiency of the multi-mode air conditioning system can largely decrease.
  • the cooling/heating operation ratio of the outdoor units can be adjusted according to the cooling/heating operation ratio of the indoor units. Therefore, the air conditioning system can have stable refrigerant cycle and high efficiency.
