Abstract: A refrigeration system of the type having an economizer cycle is provided with a null cycle, in addition to heating and cooling cycles, without shutting a compressor prime mover down, to preserve air flow in a conditioned space. First, second and third controllable valves respectively: (1) select main and auxiliary condensers, (2) open and close a liquid line, and (3) open and close a line which provides a warm liquid to an economizer heat exchanger. The valves are controlled in at least one predetermined open/close pattern during a null cycle, and preferably in a plurality of selectable predetermined open/close patterns, to provide a null cycle at any instant which substantially matches the net heat gain or loss taking place in the conditioned space. Thus, the temperature of the served space will be more apt to remain in a null temperature range close to set point, providing smoother and more accurate control over the temperature of the conditioned space for longer shelf life of perishables stored therein.

Abstract: A refrigeration system associated with a conditioned space to be controlled to a predetermined set point temperature via heating and cooling cycles. The refrigeration system includes a fluid flow path through which a predetermined liquid is circulated. The fluid flow path includes a slush tank and first and second heat exchangers, with cryogen from a supply vessel being expanded into liquid disposed in the slush tank.

Abstract: A gas turbine engine fuel system comprises a main fuel manifold and starter fuel manifold which direct fuel into the combustion apparatus of a gas turbine engine. During normal engine operation, fuel flow to the starter manifold is prevented by a solenoid valve. Air from within the combustion apparatus then flows back through the starter manifold and into a fuel drains system of the engine to purge the starter manifold of fuel. This purging of fuel in the starter manifold engine operation prevents the undesirable leakage of fuel into the combustion apparatus from the starter manifold.

Abstract: A transport refrigeration system having a dehumidifying mode. During the dehumidifying mode, a main or primary condenser is effectively removed from the active refrigerant circuit and an auxiliary or secondary condenser located in a conditioned air flow path performs the condensing function. This arrangement enables an evaporator in the air flow path to continue to cool and remove moisture from the conditioned air after a predetermined set point temperature has been reached, without a significant reduction in temperature of the conditioned air returned to a served space, as heat removed from the conditioned air by the evaporator is returned to the conditioned air by the secondary condenser.

Abstract: A transport refrigeration system, and method of operating same, in which a maximum operating pressure expansion valve and a secondary condenser are used to enhance hot gas heating cycles initiated to hold a predetermined temperature set point, and hot gas defrost cycles. The secondary condenser is disposed in an evaporator section of the refrigeration system, with hot discharge gas from a compressor being directed to the secondary condenser during heating and defrost cycles. A sufficient supply of refrigerant for heating and defrost cycles is ensured by injecting refrigerant from a receiver and condenser into an active heat cycle refrigerant circuit, when the active refrigerant is insufficient to build the pressure on the low pressure side of the refrigeration system to a value sufficient to close the maximum operating pressure expansion valve and the compressor suction pressure is less than the receiver/condenser pressure.

Abstract: A refrigeration system, and method of operating same, in which an economizer heat exchanger, normally used in conjunction with an intermediate port of a refrigerant compressor to cool the main refrigerant flow from a receiver to an evaporator to enhance the refrigerant cooling cycle, is caused to function as an evaporator during a hot gas heating cycle. The economizer heat exchanger is caused to function as an evaporator by adding heat thereto during a heating cycle, and by establishing an alternate liquid line, effective during a heating cycle, which includes the economizer heat exchanger. When the compressor is driven by an internal combustion engine, engine coolant may be used to add the necessary heat to the economizer heat exchanger during a heating cycle.
