    摘要： A fluid control system (10) includes a vortex separator (30), a fluid pump (32), an educator (34), and an accumulator (36). The vortex separator (30) has a fluid inlet arranged to receive a fluid, a first fluid outlet arranged output a first phase of the fluid, and a second fluid outlet arranged to output at least one of a non-condensable gas and a second phase of the fluid. The fluid pump (32) has a pump outlet and a pump inlet that is fluidly connected to the first fluid outlet. The eductor (34) has a first eductor inlet fluidly connected to the pump outlet, a second eductor inlet fluidly connected to the second fluid outlet, and an eductor outlet. The accumulator (36) has an accumulator inlet fluidly connected to the eductor outlet and an accumulator outlet fluidly connected to the fluid inlet.

    摘要： A refrigeration cycle apparatus (100) is a refrigeration cycle apparatus in which refrigerant circulates in an order of a compressor (1), an oil separator (2), a condenser (3), an expansion valve (4), an evaporator (5), and an accumulator (6). The refrigeration cycle apparatus (100) includes: an oil returning path (21) extending from the oil separator (2) to the compressor (1); an electromagnetic valve (7) provided on the oil returning path (21); an oil returning path (22) extending from the accumulator (6) to the compressor (1); an electromagnetic valve (8) provided on the oil returning path (22); and a controller (30) configured to control a degree of opening of the electromagnetic valve (7) and a degree of opening of the electromagnetic valve (8). Preferably, the refrigeration cycle apparatus (100) further includes a self-heating sensor (91E) configured to detect an oil level position of refrigeration oil of the compressor (1). The controller (30) is configured to: increase the degree of opening of the electromagnetic valve (8) when an output of the self-heating sensor (91E) indicates insufficiency of the refrigeration oil of the compressor (1) at a first point of time; and increase the degree of opening of the electromagnetic valve (7) when the output of the self-heating sensor (91E) indicates the insufficiency of the refrigeration oil of the compressor (1) at a second point of time subsequent to the first point of time.

    摘要： A heating, ventilation, air conditioning and refrigeration system includes a heat transfer fluid circulation loop configured to circulate a refrigerant therethrough, a purge gas outlet in operable communication with the heat transfer fluid circulation loop and at least one gas permeable membrane having a first side in operable communication with the purge gas outlet and a second side. The membrane includes a plurality of pores of a size to allow passage of contaminants through the membrane, while restricting passage of the refrigerant through the membrane, and further restricting passage of a vapor phase corrosion inhibiter through the membrane. A purge unit is in operable communication with the second side of the permeable membrane configured to receive a purge gas from the permeable membrane.
