摘要： A geothermal heating and air conditioning system having heat exchange coils located vertically in the ground is provided with a condenser receiver and a metering system which allows a relatively large amount of refrigerant to be used within the system for maximum efficiency without the problems of liquid refrigerant buildup which have been previously associated with geothermal systems using vertical coils.

摘要： A refrigeration apparatus includes a compressor, first and second heat exchangers, first and second electric valves, a passage-switching valve, a supercooling heat exchanger, and a controller. The first and second valves are disposed in first and second refrigerant passages. The supercooling heat exchanger conducts heat exchange between refrigerant flowing through the first and second refrigerant passages. The controller transitions to a defrosting operation mode upon determining that frost has formed on the second heat exchanger during a heating operation mode. The controller executes a defrosting preparatory control and a defrosting control after the defrosting preparatory control during the defrosting operation mode. The controller switches the passage-switching valve during the defrosting control. The controller narrows the opening degree of the first electric valve and controls the opening degree of the second electric valve to a minimum opening degree during the defrosting preparatory control.

摘要： When a refrigerant amount balance control is executed, in indoor units where the refrigerant supercooling degree is lower than an average refrigerant supercooling degree, the refrigerant pressure on a downstream side of indoor expansion valves decreases since the degrees of opening of the valves are decreased. On the other hand, in an indoor unit where the refrigerant supercooling degree is higher than the average refrigerant supercooling degree, although the degrees of opening of the valves are made high, the refrigerant pressure on the downstream side of the valves decreases and this decreases the refrigerant pressure on the downstream side of the indoor expansion valve, so that the difference in pressure between on the upstream side and on the downstream side of the indoor expansion valve increases and the liquid refrigerant staying at an indoor heat exchanger of the indoor unit consequently flows out into a liquid pipe.

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.

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.
