20110011105 | OIL SEPARATOR - An oil separator for use in separating oil from refrigerant gas in a chiller system is provided. Its operation is based on centrifugal separation principles and does not require the use any type of filter or media pack to remove oil from refrigerant gas. The oil separator includes a non-circular (e.g., elliptical) refrigerant outlet pipe that transitions the linear flow from the inlet connection to a swirling (e.g., circular) flow within the cylindrical housing. The non-circular shape of the entrance to the refrigerant outlet pipe provides for more turbulent gas flow and a greater extraction of oil as well as minimization of pressure losses. | 01-20-2011 |
20110017432 | COMPACT EVAPORATOR FOR CHILLERS - A compact evaporator including a suction baffle system is provided for use in a refrigeration system. The suction baffle system includes a suction baffle and a passageway. The suction baffle includes a plurality of walls and is adjacent to the interior wall of shell. The passageway extends below one of the walls of the suction baffle toward the lower portion of the shell and is adjacent to the interior wall of the shell. A suction tube having an inlet is attached to the evaporator shell and the inlet is adjacent to the passageway and located partially below the suction baffle. The passageway minimizes the possibility of liquid carry-over in the suction tube that feeds into the compressor. | 01-27-2011 |
20110056664 | VAPOR COMPRESSION SYSTEM - A distributor for use in a vapor compression system including an enclosure configured to be positioned in a heat exchanger having a tube bundle comprising a plurality of tubes extending substantially horizontally in the heat exchanger. A plurality of distribution devices are formed in the enclosure, the plurality of distribution devices configured to apply a fluid entering the distributor onto the tube bundle. The enclosure is formed of unitary construction. | 03-10-2011 |
20110120181 | FALLING FILM EVAPORATOR - An evaporator for use in a refrigeration system includes a shell and a tube bundle, the tube bundle having a plurality of tubes extending substantially horizontally in the shell. A hood is disposed over and laterally surrounds substantially all of the plurality of tubes of the tube bundle. A distributor is positioned between the hood and the tube bundle. The hood is asymmetrically disposed within the evaporator. | 05-26-2011 |
20140013782 | SYSTEM AND METHOD FOR CONTROLLING AN ECONOMIZER CIRCUIT - A system and method for controlling an economizer circuit is provided. The economizer circuit includes a valve to regulate refrigerant flow between the economizer and the compressor. The valve can be opened to engage the economizer circuit or closed to disengage the economizer circuit based on the output frequency provided to the compressor motor by a variable speed drive and an operating condition of the economizer. | 01-16-2014 |
20140013788 | HEAT-PUMP CHILLER WITH IMPROVED HEAT RECOVERY FEATURES - A heating and cooling system includes an evaporator, a compressor, and a condenser. A heat exchanger, which may be an outdoor heat exchanger, is configured to receive the refrigerant from the condenser, to selectively extract heat from or to add heat to the refrigerant, and to transfer the refrigerant to the evaporator. First control valving, disposed between the condenser and the heat exchanger, is configured to regulate flow of the refrigerant from the condenser to the heat exchanger in a first mode of operation. Second control valving, disposed between the condenser and the heat exchanger, is configured to regulate flow of the refrigerant from the heat exchanger to the evaporator in a second mode of operation. The system may be operated in a variety of modes by appropriate control of the valving and other system components. | 01-16-2014 |
20140260376 | SUBCOOLING SYSTEM WITH THERMAL STORAGE - Embodiments of the present disclosure are directed toward systems and method for cooling a refrigerant flow of a refrigerant circuit with a cool water flow from a cool water storage to generate a warm water flow and to cool the refrigerant flow by a subcooling temperature difference, flowing the warm water flow to the cool water storage, and thermally isolating the warm water flow from the cool water flow in the cool water storage. | 09-18-2014 |
20140318162 | SYSTEM AND METHOD FOR REDUCING NOISE WITHIN A REFRIGERATION SYSTEM - A method is provided including receiving a first input indicative of a desired design capacity of a refrigeration system, and receiving a second input indicative of a desired maximum acoustical noise of the refrigeration system. The method also includes iteratively selecting a candidate compressor system from a set of compressor systems, and iteratively selecting a candidate condenser system from a set of condenser systems. In addition, the method includes simulating operation of the refrigeration system based on the candidate compressor system and the candidate condenser system until a suitable refrigeration system is established having a computed design capacity greater than or equal to the desired design capacity, and a computed maximum acoustical noise less than or equal to the desired maximum acoustical noise. The method further includes providing an output indicative of the candidate compressor system and the candidate condenser system of the suitable refrigeration system. | 10-30-2014 |
