    摘要: An object is to provide a refrigeration cycle apparatus that does not cause unevenness of capacity among branch units and a failure in controlling a refrigerant circuit. At least one of branch units is a first branch unit having a minimum pressure loss in distribution of refrigerant in a high-pressure refrigerant pipe between a heat source unit and the branch units, and at least another one of the branch units is a second branch unit having a maximum pressure loss in distribution of refrigerant in the high-pressure refrigerant pipe between the heat source unit and the branch units. An opening degree of an expansion device is controlled in such a manner that a differential pressure between a refrigerant pressure detected by a high-pressure detecting device of the first branch unit and a refrigerant pressure detected by an intermediate-pressure detecting device is greater than or equal to a set value ΔPHM.

    摘要: An air conditioning apparatus includes a compressor, indoor and outdoor heat exchangers, an indoor fan, an expansion valve, a refrigerant-pressure-perceiving part, which perceives a pressure of refrigerant sent from the compressor to the indoor heat exchanger, and a control part, which performs startup fan control in which the indoor fan remains stopped until the compressor goes from being at rest to starting up and the pressure perceived reaches a high-pressure threshold. The control part repeats an action of reducing a flow rate of the indoor fan or stopping driving of the indoor fan when the pressure perceived is equal to or less than a low-pressure lower than the high-pressure threshold, and an action of increasing the flow rate of the indoor fan or initiating driving of the indoor fan when the pressure perceived reaches or exceeds a pressure threshold which is higher than the low-pressure threshold.

    摘要: A refrigerant vapor compression system includes a flash tank receiver disposed in the refrigerant circuit intermediate the refrigerant cooling heat exchanger and the refrigerant heating heat exchanger. The flash tank receiver, which receives a liquid/vapor refrigerant mix, also functions as a receiver. A refrigerant charge control apparatus includes at least one sensor for sensing an operating characteristic of the refrigerant circulating through the refrigerant compression device, and a controller operative to selectively adjust a secondary expansion device to increase or decrease the flow of refrigerant passing into the flash tank receiver to provide a circulating refrigerant charge consistent with maintaining a desired system operating characteristic. The sensed operating characteristic is at least one of (a) the vapor refrigerant passing through a refrigerant line from the flash tank receiver to an intermediate pressure stage of the compression device, and (b) the refrigerant discharged from the compression device.
