COMPRESSED-GAS REGULATOR APPARATUS

摘要

Compressed-gas regulator apparatus (10 ) for controlling a pressurised OFN supply, comprises a regulator housing (20) having a regulator gas inlet (24), a regulator gas outlet (16) and a flow path therebetween. The gas inlet (24) is releasably connectable to an outlet (26) of the OFN supply (28). An electrically-operable regulator valve (30) in the housing for controlling a flow of gas along the flow path is also provided, along with a pressure sensing device in the housing for sensing a backpressure at or from the gas outlet (16). A regulator user-interface (36) for inputting a backpressure value, a local regulator controller for automatically closing the valve when the user-selected backpressure is reached, a wireless regulator receiver in the housing (20) for remotely controlling the local regulator controller, and a discrete remote controller (18) having a remote user-interface (80) and a wireless transmitter for wirelessly transmitting a control signal to the wireless regulator receiver are also included. Preferably, a splitter device (14) is also included. The splitter device (14) comprises a splitter housing (48) having a splitter gas inlet (50) which is connectable to the regulator gas outlet (16), at least a suction gas outlet (52) for connection to a suction line of an air conditioning system and a liquid gas outlet (56) for connection to a liquid line of an air conditioning system, a local splitter controller having a splitter user-interface (60) on the splitter housing (48), at least one electrically-operable splitter valve controllable by the splitter controller for selectively connecting the splitter gas inlet (50) to the suction gas outlet (52) or the liquid gas outlet (56), and a wireless receiver in the housing for remotely controlling the splitter controller via the said remote controller (18).The splitter device (14) may also be provided independently of the regulator device. In this case, the wireless receiver and the remote controller (18) may be optional.
