摘要： An Improved Refrigeration System and Heating/Defrost Cycle is disclosed. The system, for heating circulating air and defrosting an enclosed area, includes a refrigerant, an evaporator using said refrigerant for heating the circulating air; and a compressor for receiving the refrigerant from the evaporator and compressing the refrigerant to a higher temperature and pressure. Advantageously, the system further includes the combination of an expansion valve positioned between the compressor and the evaporator for forming a partially expanded refrigerant, a controller for sensing system parameters, and a mechanism responsive to said controller, based on the sensed parameters, for increasing temperature differential between the refrigerant and the circulating air, for improving system efficiency and for optimizing system capacity during heating and defrost cycles.

摘要： A refrigeration system for cooling air s disclosed. The system includes a substantially liquid refrigerant and an evaporator for transferring heat from the air to the substantially liquid refrigerant. The substantially liquid refrigerant becomes a low temperature, low pressure first superheated gas refrigerant. A compressor compresses the first superheated gas refrigerant into a high pressure, high temperature second further superheated gas refrigerant. A lubricant circuit supplies lubricant to the compressor, wherein a portion of the lubricant is mixed with the further superheated gas refrigerant. A condenser rejects heat from the second superheated gas refrigerant and forms a high pressure, low temperature sub-cooled liquid refrigerant. The condenser has an output stream. A metering device transforms the sub-cooled liquid refrigerant into the substantially liquid refrigerant for the evaporator. An economizer circuit provides an intermediate temperature and pressure economizer refrigerant flow to the compressor. The economizer refrigerant flow originates from the output stream of the condenser. The economizer circuit includes an economizer heat exchanger. The economizer heat exchanger includes paths for receiving and cooling the lubricant before returning to the compressor and the sub-cooled liquid refrigerant on route to the metering device, wherein the economizer refrigerant flow is a cooling medium in the heat exchanger.

摘要： An improved apparatus and method for injecting a liquid/vapor into compression chambers at an intermediate pressure utilizes the economizer injection ports already found in the compressor. By selectively communicating a liquid to be injected into the compression chambers to the economizer return line, the economizer return line and its ports are utilized for this liquid/vapor injection. In this way, no additional flow connections at the compressor are necessary. Moreover, by injecting the liquid at an intermediate pressure point, the other benefits are provided. In general, the liquid is injected to reduce the discharge temperature of the refrigerant under certain operational conditions.

摘要： A refrigerant system is provided where the functions of an economizer heat exchanger and liquid-suction heat exchanger are combined. The two configurations are disclosed with a single common heat exchanger construction. In a first configuration, a series of valves selectively routes only one of two possible refrigerant flows through a common heat exchanger such that a control can selectively activate either an economizer heat exchanger circuit or a liquid-suction heat exchanger function. In a second configuration, both refrigerant flows are passed to the common heat exchanger through separate fluid lines and are selectively activated by the control. Variations of the second configuration are also disclosed.

摘要： A refrigeration system for cooling air is disclosed. The system includes a substantially liquid refrigerant and an evaporator for transferring heat from the air to the substantially liquid refrigerant. The substantially liquid refrigerant becomes a low temperature, low pressure first substantially gaseous refrigerant. A compressor compresses the first substantially gaseous refrigerant into a high pressure, high temperature superheated second gaseous refrigerant. A lubricant circuit supplies lubricant to the compressor. A condenser rejects heat from the second gaseous refrigerant and forms a high pressure, lower temperature sub-cooled liquid refrigerant. The condenser has an output stream. A metering device transforms the sub-cooled liquid refrigerant into the substantially liquid refrigerant for the evaporator. A heat exchanger receives the first substantially gaseous refrigerant as a coolant on route to the compressor. The first substantially gaseous refrigerant is relatively cooler than the lubricant and the sub-cooled liquid refrigerant. The lubricant via the lubricant circuit flows through the heat exchanger and cools prior to entering the compressor and the sub-cooled liquid refrigerant flowing through the heat exchanger means sub-cools prior to entering the metering device.

摘要： In a low side hermetic compressor, a small portion of the compressed refrigerant gas is diverted and discharged into the oil sump through an orifice into the upper level of the oil in the sump. This results in a supersaturated solution of refrigerant in oil in the upper level which drives the refrigerant out of the oil, thereby creating froth which provides sound reduction without disturbing the lower level which remains stratified. A check valve is provided for preventing reverse flow while requiring a predetermined pressure differential for diversion.

摘要： A crush tube is used to provide a fluid connection between a first and second member. The crush tube has two tubular portions with a spherical portion therebetween. The tubular portions are loosely received in nominally coaxial bores having entrance chamfers. The spherical portion is deformed into contact with the chamfers as well as between the members whereby the tube provides a sealed fluid path between the bores.

摘要： Oil normally having refrigerant gas entrained therein is drawn from a sump. A portion of the oil is returned to the sump to agitate the oil in the sump to enhance gas separation therefrom. The remainder of the oil is subjected to centrifugal separation to remove the entrained refrigerant. The separated refrigerant is vented while the separated oil is fed to the lubrication system where contaminant removal takes place.
