Abstract:
An oil balancing system for a multiple compressor system is provided. The oil balancing system includes an oil equalization line disposed between a first compressor and a second compressor. A first solenoid valve is provided in the oil equalization line. A first signal corresponds to a first oil level in the first compressor. A second signal corresponds to a second oil level in the second compressor. An oil balancing module uses the first signal and the second signal to diagnose an oil imbalance between the first compressor and the second compressor, and applies corrective action, whereby the corrective action includes sending control signals to operate at least one of the first compressor, the second compressor, or the first solenoid valve in a way that eliminates the oil imbalance.
Abstract:
The present invention relates to a compressor for a heat pump, and to a heat pump system using same, wherein the compressor comprises: a sealed vessel partitioned by a diaphragm member into an upper chamber and a lower chamber; a motor disposed in the upper chamber, a rotating shaft of which passes through a shaft support of the diaphragm member so as to project into the lower chamber; an impeller installed on the bottom of the rotating shaft; and a nozzle disposed in the lower chamber, for spraying high pressure coolant so as to rotate the impeller as well as the rotating shaft of the motor, to thereby reduce energy consumption by lightening the load on the motor. The compressor for a heat pump according to the present invention comprises: said sealed vessel (20) partitioned by the diaphragm member (21) into the upper chamber (22) and the lower chamber (23); a pump (32) and said motor (34) built into the sealed vessel (20), wherein the pump (32) and the motor (34) are installed in the upper chamber (22), the pump (32) is driven by the motor (34), coolant that is taken in through an inlet (25) is compressed by the pump (32) and discharged through a discharge hole (26), and the bottom end of the rotating shaft (35) of the motor (34) passes through the shaft support (24) of the diaphragm member (21) so as to project into the lower chamber (23); said impeller (40) installed on the bottom of the rotating shaft (35); and said nozzle (50) disposed in the lower chamber (23), for spraying high pressure coolant so as to rotate the impeller (40) as well as the rotating shaft (35) of the motor (34) by means of the rotation of the impeller (40).

Um einen Kompressor für Kältemittel umfassend ein Außengehäuse, einen Spiralverdichter mit einem ersten feststehend im Außengehäuse angeordneten Verdichterkörper und einen zweiten, relativ zum ersten Verdichterkörper bewegbaren Verdichterkörper, welche so ineinander greifen, dass zum Verdichten des Kältemittels der zweite Verdichterkörper gegenüber dem ersten Verdichterkörper auf einer Orbitalbahn um eine Mittelachse bewegbar ist, eine Antriebseinheit für den zweiten Verdichterkörper mit einem Exzenterantrieb, einer Antriebswelle, einem in einem Motorgehäuse angeordneten und vom angesaugten Kältemittel umströmten Antriebsmotor sowie einer Lagereinheit für die Antriebswelle, welche einen ersten, mit dem Außengehäuse verbundenen Lagerkörper umfasst, derart zu verbessern, dass ein möglichst geringer Anteil von Flüssigkeitströpfchen im vom Spiralverdichter zu verdichtenden Kältemittel vorliegt, wird vorgeschlagen, dass das Kältemittel vor dem Umströmen des Antriebsmotors eine Flüssigkeitströpfchen zerstäubende Einströmkammer durchströmt, welche innerhalb des Außengehäuses sowie zwischen dem Außengehäuse und einem Motorgehäuse der Antriebseinheit angeordnet ist.
Abstract:
We provide a compressor or vacuum pump fluid intake manifold having a fluid intake and a pair of ports provided by male and female fittings that are slidably engaged to one another. The male fitting has a portion which forms a hollow plug which fits within a respective fluid intake of the compressor housing. The plug portion, or plug, is integrally molded with a longitudinal section of the male fitting member. In similar fashion, the female fitting includes a plug portion which interfaces with a fluid intake in the compressor housing. The plug portion is integrally molded with a longitudinal portion of the female fitting. In one embodiment, each of the plugs includes three extending flanges forming an integral portion of the plug. Two of the three flanges are furtherest away from the plug. These two flanges provide a contact pressure seal with portions of the compressor housing that define the fluid intakes which receive the plugs. The other plug serves to prevent the plugs from slipping out of the fluid intakes during normal use of the fluid intake manifold. Further, instead, each of the plugs can have a raised insert surface defining a groove with an O-ring and a flange integral with and extending from a surface of the plug. The O-ring provides a contact pressure seal with portions of the housing defining the compressor intake. The radially extending flange serves to inhibit the removal of the plug from the compressor intakes during normal use of the fluid manifold.
Abstract:
The present invention relates to a compressor, a method of welding a fluid tubing to a compressor housing, and a fluid-transport tubing, particularly applicable to an airtight compressor, which provide for the replacement of the brazing step and the direct welding of the fluid-passage tubing to the compressor housing. The airtight compressor comprises a housing (5) and a fluid-transport tubing (9), the fluid-transport tubing passing through the housing (5) through a passage orifice (10), the fluid-transport tubing (9) comprising weldable coupling means (11 ), the weidable coupling means (110) being configured from a widening in the diameter of the fluid- transport tubing (9), the widening in the diameter having a dimension larger than the diameter of the passage orifice (10) and being configured along its length, the weldable means (11 ) being welded directly close to a border (12') of the passage orifice (10). A method of welding the fluid tubing to a compressor housing, as well as a fluid-transport tubing, particularly applicable to an airtight compressor, are also described.
