Abstract:
A dehumidifier is provided, the dehumidifier includes a housing, and a condenser and an evaporator arranged inside of the housing that are each formed into a generally circumferentially extending C shape and arranged to be generally coaxial and aligned with one another. A compressor and a fan are each centrally located in the housing, with the fan located above the compressor. A collection pan is located under the evaporator, and a water tank is located above the condenser, evaporator, and the compressor. A pump is provided to direct the collected water to the water tank.
Abstract:
An oil/gas separator comprises a duct (20) having an inlet (13) for receiving an oil/gas mixture, the duct having an inner surface extending at least partially in a horizontal direction and providing a bend (32) or series of bends. The duct (20) provides at least partial separation of the oil/gas mixture, in use, by both gravitational and centrifugal oil collection onto the inner surface. The duct is arranged to deliver gas and collected oil into a centrifuging cylinder (22) providing an internal impingement surface, an upper gas outlet (30), and a lower oil outlet (24). The cylinder (22) has an internal diameter of less than 180 mm. Thus, the oil separator of this invention is in effect formed by the pipework that is required to recirculate refrigerant.
Abstract:
Die Erfindung betrifft eine Wärmepumpe, umfassend einen wahlweise im Heiz- oder Kühlbetrieb betreibbaren Kältemittelkreislauf (1) mit einem Kältemittelsammler (2), an dem eine erste Öffnung (2.1) zur Zufuhr von Kältemittel aus dem Kältemittelkreislauf (1) im Heizbetrieb und zur Abfuhr von Kältemittel in den Kältemittelkreislauf (1) im Kühlbetrieb und eine zweite Öffnung (2.2) zur Abfuhr von Kältemittel in den Kältemittelkreislauf (1) im Heizbetrieb und zur Zufuhr von Kältemittel aus dem Kältemittelkreislauf (1) im Kühlbetrieb vorgesehen ist, wobei die erste Öffnung (2.1) oberhalb der zweiten Öffnung (2.2) angeordnet ist, wobei der Kältemittelkreislauf (1) einen ersten, im Heizbetrieb als Kondensator arbeitenden Wärmeübertrager (3) und ein Expansionsventil (4) aufweist und wobei der Kältemittelsammler (2) zwischen dem ersten Wärmetauscher (3) und dem Expansionsventil (4) angeordnet ist. Nach der Erfindung ist vorgesehen, dass ein Abstand zwischen den beiden Öffnungen (2.1, 2.2) orientiert an einer für den Kühlbetrieb erforderlichen Menge an Kältemittel festgelegt ausgebildet ist.
Abstract:
Embodiments of the present disclosure relate to a heating, ventilation, air conditioning, and refrigeration (HVAC&R) system (10) that includes a refrigerant loop (100), a compressor (32) disposed along the refrigerant loop and configured to circulate refrigerant through the refrigerant loop, and an evaporator (38) disposed along the refrigerant loop and configured to place the refrigerant in thermal communication with a cooling fluid, where the refrigerant (126) surrounds a tube bundle (110) disposed in the evaporator, the tube bundle is configured to flow the cooling fluid, and the evaporator (38) has a height (102) based at least on a target height of a liquid level (108) of refrigerant in the evaporator, the evaporator includes a discharge (118) configured to direct the vapor refrigerant (120) from the evaporator to an inlet of the compressor (32), and an interface between the discharge and the inlet is without a bend.
Abstract:
A heat pump includes an evaporator for evaporating working liquid within an evaporator space (102) bounded by an evaporator base (108), and a condenser for condensing evaporated working liquid within a condenser space (104) bounded by a condenser base (106), the evaporator space being at least partially surrounded by the condenser space, the evaporator space (102) being separated from the condenser space (104) by the condenser base (106), and the condenser base (106) being connected to the evaporator base (108).
Abstract:
A method and apparatus for use with a heat exchange system having a compressor, condenser, evaporator, an expansion device, and circulating refrigerant is provided. The apparatus comprises a chamber positioned between the condenser and the evaporator. According to an embodiment of the invention, the chamber comprises a down tube with holes for the passage of refrigerant from the chamber and a top inlet port comprising a vapor expansion screen. The suction of the refrigerant through the holes draws refrigerant towards the top inlet port past the vapor expansion screen, allowing for further cooling within the chamber. When the refrigerant eventually exits the chamber, it is considerably cooler than when it entered the vessel, making the entire refrigeration system more efficient.
