摘要： A hot gas heat treat system is employed to cool mix in a hopper and a freezing cylinder and to heat the mix for pasteurization. A hopper liquid line solenoid valve at the inlet of the hopper and a cylinder liquid line solenoid valve at the inlet of the freezing cylinder each control the flow of refrigerant to the expansion valves which further control the flow of refrigerant that flows around the hopper and the freezing cylinder, respectively. A hopper hot gas solenoid valve at the inlet of the hopper and a cylinder hot gas solenoid valve at the inlet of the freezing cylinder control the flow of refrigerant from the compressor that flows around the hopper and the freezing cylinder. The system further includes a hot gas bypass valve that is opened when only the hopper is being cooled to provide additional load to the compressor. An EPR valve is positioned proximate to the hopper discharge to vary the temperature of the refrigerant exchanging heat with the hopper. A CPR valve is employed to control the inlet pressure of the compressor by reducing the amount of hot refrigerant flowing into the compressor suction. The system further includes a TREV valve to allow for liquid refrigerant injection to the compressor suction to control excessive compressor discharge during the cool cycle.

摘要： In one aspect, the present invention relates to a refrigeration control system that is modular and contains an algorithm to control the energy and temperature performance of side-by-side, top mount, and bottom mount type refrigerators. The control algorithm uses a two-dimensional control grid to determine the state of the refrigeration system based on the temperature of the freezer compartment and the fresh food compartment. The control algorithm then controls the rate of the fresh food fan, evaporator fan, and the damper and to bring the refrigerator-freezer to a desired state and maintain that state.

摘要： A closed circuit refrigeration system of successive coalescent/depth filters provides the almost total removal of liquid refrigerants from a refrigeration gas stream. The liquid refrigerant so extracted is then be returned to the suction side through a metering device such as a capillary line to provide intermediate cooling of the oncoming discharge gas. The auto cascade system utilizes short path plate heat exchangers. The properties of coalescent/depth filters place a physical barrier between the differing temperature/pressure regimes on the discharge side of the system. The provision of a start valve in a line connecting the gas discharge path and the return path close to the cryo-coil enables the use of hermetic compressors and eliminates the requirement for supplementary pressure vessels within auto-cascade cryogenic refrigeration systems.

摘要： A concentric tubing apparatus prevents heat gain in an air conditioning system. The heat gain results from heat generated in an engine compartment of a vehicle. To accomplish this, the tubing apparatus includes a first and second refrigerant tubes. The first refrigerant tube is in fluid communication with a receiver and an evaporator of the air conditioning system to accommodate the flow of the refrigerant from the receiver to the evaporator, and the second refrigerant tube is in fluid communication with the receiver and the evaporator to accommodate the flow of the refrigerant from the evaporator to the receiver. The second refrigerant tube is disposed concentrically about the first refrigerant tube such that the second refrigerant tube insulates the refrigerant flowing in the first refrigerant tube from the heat generated in the engine compartment. Thus, heat gain in the refrigerant flowing in the first refrigerant tube to the evaporator is prevented.

摘要： A refrigerating cycle apparatus is used in an air-conditioning system of an automotive vehicle, which is capable of operating in a hot gas bypass heating mode. Here, the discharge side of a compressor is directly connected through a hot gas bypass conduit to the inlet side of an evaporator. The evaporator acts as a radiator, heated by gas refrigerant. The compressor is stopped during operation of the apparatus in this heating mode when a physical quantity representing the high-side pressure at the compressor discharge side rises above a set value. The compressor is restarted when a physical quantity representing a heating capacity (for example the high-side pressure) falls below a set value which indicates that there is no heating capacity in the stopped state of the compressor. As a result, the heating capacity obtained through hot gas bypass can be controlled well without frequent stopping and restarting of the compressor.
