摘要： An air conditioning system can be toggled between a heating mode, in which heat is withdrawn from a source (e.g., a geothermal source) and deposited into a conditioned space (e.g., a building), and a cooling mode, in which heat is withdrawn from the conditioned space and deposited into the source. The air conditioning system uses a combination of efficiency-enhancing technologies, including injection of superheated vapor into the system's compressor from an economizer circuit, adjustable compressor speed, the use of one or coaxial heat exchangers and the use of electronic expansion valves that are continuously adjustable from a fully closed to various open positions. A controller may be used to control the system for optimal performance in both the heating and cooling modes, such as by disabling the economizer circuit and vapor injection when the system is in the cooling mode.

摘要： A heat pump system includes a compressor, indoor heat exchanger, outdoor heat exchanger, and expansion valve. A main flow control device fluidly couples a discharge line to the outdoor heat exchanger when the heat pump system is in a cooling mode, and fluidly couples the discharge line to the indoor heat exchanger when the heat pump system is in a heating mode. An intermediate heat exchanger is configured to receive working fluid from the outdoor heat exchanger in a cooling mode and from the indoor heat exchanger in a heating mode. The intermediate heat exchanger is configured to superheat or sub-cool a working fluid therein. A secondary flow control device is configured to control a directional flow of working fluid between the indoor heat exchanger, the outdoor heat exchanger and the intermediate heat exchanger. A controller is operably coupled to the main and secondary flow control devices.

摘要： An air conditioner includes a compressor, an outdoor heat exchanger, an indoor heat exchanger, a converting unit, an accumulator, and injection module, a supercooling valve, and an injection valve. The injection module expands and vaporizes a portion of refrigerant flowing from the indoor heat exchanger to the outdoor heat exchanger in the heating operation. The supercooling valve is disposed between the injection module and the accumulator and is opened to direct the portion of the refrigerant vaporized in the injection module to the accumulator in the heating operation and then closed after a predetermined time passes. The injection valve is disposed between the injection module and the compressor and is opened when the supercooling valve is closed in the heating operation, thereby injecting the portion of the refrigerant vaporized in the injection module to the compressor.

摘要： The refrigerant discharged from a compressor is distributed based on the priorities set by the user in advance and the remaining refrigerant is further distributed based on the priorities. Thus, setting the priorities for indoor units according, for example, to the usage of work spaces and the like in an office building, the user can operate a heat pump system efficiently in accordance with the intended use. Furthermore, the remaining capacity of the outdoor unit is distribute to the remaining indoor units according to their priorities so that the indoor units are operated efficiently within the range of the cooling capacity of the outdoor unit.
