One end of the bypass circuit is connected to an intake conduit of the expander and the ... 05/03/07 - 20070095084 - Apparatus and method for controlling multi-type air conditioner A method for controlling a multi-type air conditioner, includes selecting, from among a plurality of indoor units connected to an outdoor unit, at least one currently operating indoor unit; determining whether the at least one currently operating indoor unit is in an overcooling state; selecting, from among the plurality of ... 05/03/07 - 20070095083 - Method and apparatus for removing partial overload in an air conditioner A method for removing a partial overload in an air conditioner, which includes determining whether a plurality of indoor units provided in the air conditioner includes at least one indoor unit operating in an overload state; and performing a partial overload operation to increase the amount of a refrigerant introduced ... 04/05/07 - 20070074524 - Cooling system methods and apparatus for a refrigeration device A refrigerator includes a housing defining at least one chamber and a condenser system in which a refrigerant flows. The condenser system includes a condenser, a switching device, and a hot gas loop in flow communication with one another. The condenser system is configured to be in heat transfer relation ... 01/04/07 - 20070000263 - Method and system for packaging hvac components An apparatus and method of controlling a heating and cooling system may include utilizing a heating, ventilation, and air conditioning (HVAC) module for an HVAC system. The HVAC module may include an input port, a compressor connected to the input port, a condenser connected to the compressor, a heat exchanger ... 10/12/06 - 20060225447 - Cooling unit A cooling unit which contains refrigerant for exchanging heat with an object member of cooling includes a refrigerant passage and cooling means. The refrigerant passage allows the refrigerant to circulate therethrough. The cooling means communicates with the refrigerant passage for supplying the refrigerant passage with the refrigerant. The cooling means ... 07/13/06 - 20060150647 - Gas removing apparatus for removing non-condensate gas from a heat pipe and method for the same A method and gas removing apparatus removes non-condensate gas from a heat pipe. The gas removing apparatus includes at least one heating unit, a sealing unit and a height-adjusting unit. The heating unit heats the heat pipe and includes a clip to clamp the heat pipe. The sealing unit is ... 03/30/06 - 20060064997 - Cooling systems An apparatus has a compressor having suction and discharge ports. One or more conduits form a main flowpath from the discharge port through a condenser, a heat exchanger first leg, a first expansion device, and an evaporator to return to the suction port. The conduits also form a bypass flowpath ... 02/23/06 - 20060037336 - Compressor loading control A system has a number of parallel flowpath segments between a compressor and an evaporator. One or more valves selectively block and unblock at least one of the segments to provide capacity control. ... 02/16/06 - 20060032254 - Air conditioning system and control method thereof An air conditioning system includes an indoor heat exchanging unit, an outdoor heat exchanging unit, a compressor forming a closed loop together with the indoor and outdoor heat exchanging units to compress refrigerant, and a compressor driver to drive the compressor. The air conditioning system also includes an outdoor temperature ... 12/01/05 - 20050262859 - System and method for controlling an economizer circuit A control algorithm for controlling an economizer circuit in a chiller system is provided. The control algorithm opens and closes a port valve in the economizer circuit in response to predetermined criteria to engage and disengage the economizer circuit. The predetermined criteria can include an operating parameter of a compressor ... 11/10/05 - 20050247071 - Capacity control for economizer refrigeration systems An economizer-equipped refrigeration system and method is provided for simultaneous operation of at least one capacity control valve controlling an independent bypass circuit with operation and variable control of the economizer circuit to permit efficient, flexible, and reliable variable system capacity control, without leakage that sacrifices system peak capacity. ... 10/27/05 - 20050235667 - Refrigerator and control method thereof A refrigerator and a control method thereof in which a smooth flow of a refrigerant can be provided through an effective control for a path change valve when a flow path of the refrigerant is changed between two evaporators having different pressures. The refrigerator includes low-pressure-side and high-pressure-side evaporators, a ... 10/06/05 - 20050217292 - Refrigeration system A refrigerating system comprises a compressor, a condenser, an expansion valve, an evaporator, sensors for detecting respectively a temperature and a pressure of a refrigerant sucked into the compressor, and a pressure of a refrigerant discharged from the compressor, a liquid injection system including an injection passage and a flow ... 09/29/05 - 20050210898 - Refrigerator and control method thereof A refrigerator and a control method thereof in which a smooth flow of a refrigerant can be provided through an effective control for a path change valve when a flow path of the refrigerant is changed between two evaporators equipped in the refrigerator by the path change valve.
