ABSTRACT:
An air-conditioner system having a compressor, a plurality of heat exchangers for heating or cooling the air in a room, a radiator for transferring heat energy of refrigerant outside of the room, a plurality of orifices, a manifold with a main port and a plurality of sub-ports, flow direction control multi-port valves directing the flow of the refrigerant from the compressor to the main port and not from the main port to the compressor when at least one of the heat-exchangers is heating the room. The refrigerant does not flow from the compressor to the radiator when at least one of the heat exchangers is heating and none of the heat exchangers is cooling. Also, it does not flow from the compressor to the main port but flows instead from the compressor to the radiator and from the main port to the compressor when none of the heat exchangers is heating and at least one of the heat exchangers is cooling. The system also employs a plurality of valve pairs each of which having a first valve and second valve such that the first valve opens (closes) when the second valve closes (opens). The first valves are arranged for providing flow of refrigerant to the inlet of the compressor from the heat exchangers and the second valves provide flow of refrigerant from the outlet port of the compressor to the respective heat exchanger first ports via the sub-ports of the manifold.
