摘要: A performance degradation diagnosis system includes a determining unit, and control unit. A refrigeration cycle apparatus includes a refrigerant circuit having a compressor, heat-source-side heat exchanger, and use-side heat exchanger. The determining unit determines, based on an index indicating an operation state of the refrigeration cycle apparatus, performance degradation of the refrigeration cycle apparatus with respect to each of a plurality of performance degradation factors. In a case in which the determining unit determines performance degradation, the control unit grasps an operation condition of the refrigeration cycle apparatus which is operating. In a case in which the operation condition of the refrigeration cycle apparatus is not suitable to determine performance degradation with respect to a performance degradation factor of a determination target, the control unit controls the operation condition of the refrigeration cycle apparatus so that the operation condition of the refrigeration cycle apparatus becomes an appropriate operation condition.

摘要: A dynamic receiver is included in parallel to an expander of a heating, ventilation, air conditioning, and refrigeration (HVACR) system. The dynamic receiver allows control of the refrigerant charge of the HVACR system to respond to different operating conditions. The dynamic receiver can be filled or emptied in response to the subcooling observed in the HVACR system compared to desired subcooling for various operating modes. The HVACR system can include a line directly conveying working fluid from compressor discharge to the dynamic receiver to allow emptying of the dynamic receiver to be assisted by injection of the compressor discharge.

摘要: An integrated receiver drier and economizer (RDE) includes a tank having a hollow interior receiving a first flow of a refrigerant therein, the first flow of the refrigerant including a liquid phase of the refrigerant accumulating within a liquid containing portion of the hollow interior of the tank. An economizer receiving a second flow of the refrigerant through an interior thereof is at least partially submerged in the liquid containing portion of the tank. The economizer forms a heat exchanging structure configured to exchange heat between the first flow of the refrigerant passing over an exterior of the economizer and the second flow of the refrigerant passing through the interior of the economizer. A desiccant is disposed in the liquid containing portion of the tank downstream of the economizer with respect to the first flow of the refrigerant through the hollow interior of the tank.

摘要: A refrigeration system comprises: a compressor, a first heat exchanger, a reservoir, a throttling element and a second heat exchanger in the refrigeration circuit. The refrigeration system comprises a cooling mode and a hot-gas bypass heating mode. In the hot-gas bypass heating mode, the refrigerant leaving the outlet of the compressor is delivered directly to the second heat exchanger before returning to the inlet of the compressor, wherein, the refrigeration system further comprises a branch flow path with a control valve provided thereon. The control valve is capable of being opened or closed in the hot-gas bypass heating mode.
