摘要： A compressor (36) of a heating, ventilation, and air conditioning (HVAC) system (30) includes a casing (104) having an inner volume (106) and an inner surface (112) defining the inner volume (106), where the inner volume (106) is configured to accommodate a rotor (108) therein. The compressor (36) also includes an economizer port (102) formed in the casing (104) and configured to inject a flow of fluid (120) into the inner volume (106) and a valve (100) disposed within the economizer port (102) and configured to regulate the flow of fluid (120) into the inner volume (106). The valve (100) has an inward-facing surface (140), and the inward-facing surface (140) is aligned with the inner surface (112) of the casing (104) in a closed position of the valve (100).

摘要： A scroll compressor including an orbiting scroll having a small diameter compared to a case in which an oil groove is provided in a ring shape and constantly communicates with an outlet of an oil passage. The scroll compressor includes a fixed scroll and an orbiting scroll configured to orbit in engagement with the fixed scroll. The fixed scroll includes an outlet of an oil passage configured to communicate with an oil tray storing lubricant, the outlet of the oil passage connected to a sliding surface of the orbiting scroll. The orbiting scroll includes a plurality of oil grooves configured not to communicate with each other so as to supply the lubricant to a sliding surface of the fixed scroll, the plurality of oil grooves configured to communicate with the outlet at least once and not to communicate with the outlet at least once while the orbiting scroll rotates once.

摘要： A compressor includes a shell, first and second scroll members, a fitting assembly and a valve assembly. The first scroll member includes a first end plate having a first spiral wrap extending therefrom. The second scroll member includes a second end plate having a second spiral wrap extending therefrom and an injection passage formed in the second end plate. The second spiral wrap is meshingly engaged with the first spiral wrap to form compression pockets. The injection passage is in fluid communication with the compression pockets. The fitting assembly is in fluid communication with the injection passage. The valve assembly coupled to one of the second scroll member and the fitting assembly and movable between a closed position in which fluid communication between the compression pockets and the suction chamber is prevented and an open position in which fluid communication between the compression pockets and the suction chamber is allowed.

摘要： Systems and methods for purging lubricant from a first compressor to a second compressor are provided. A control module receives a lubricant purge command, shuts the second compressor to an OFF-mode while the first compressor remains in the ON-mode, restricts working fluid from an outlet of the second compressor from flowing into the first compressor and allows compressed working fluid discharged from an outlet of the first compressor to flow into the inlet of the second compressor such that lubricant in the second compressor flows into the first compressor.

摘要： New device to protect a compressor against liquid flooding, oil heater malfunction, low refrigerant charge, high superheat. The system consists of a device that measures two temperatures separated by a heat source (The electric compressor or the suction heat exchanger or both). The temperature difference can detect a liquid return to the compressor, a high superheat, a low refrigerant charge or a crankcase heater malfunction and the temperature difference can control the electronic expansion valve.
