摘要： A transport refrigeration system having electrical control which controls the temperature in a served space via heating and cooling cycles using hot refrigerant gas from a refrigerant compressor. The refrigeration system has high and low pressure sides. The high pressure side includes a discharge manifold of the compressor, a condenser coil, a refrigerant receiver tank, and an evaporator coil associated with the served space. The low pressure side extends from the evaporator coil to a suction manifold of the compressor. A first controllable refrigerant flow path means is controlled by the electrical control to purge the condenser coil in response to predetermined system parameters, causing refrigerant trapped in the condenser coil to flow to the low pressure side of the system. A second controllable refrigerant flow path is controlled by the electrical control to pressurize the receiver tank in response to predetermined system parameters, forcing refrigerant to flow from the receiver tank to the evaporator coil.

摘要： A diesel engine system in which fuel in a fuel tank having an air space above a fuel level is pumped to a fuel injection system disposed in spaced relation above the fuel tank, and excess fuel is returned to the fuel tank air space via an uninterrupted fluid flow path between the injection system and the air space of the fuel tank. The fluid flow path has a cross sectional area selected such that air from the fuel tank air space flows counter to fuel returning to the fuel tank by gravity during non-operation of the diesel engine, to maintain the space vacated by returning fuel near atmospheric pressure. A method embodiment includes the steps of providing an uninterrupted fluid flow return path between the injection system and the air space of the fuel tank, and sizing the fluid flow return path such that, during non-operation of the diesel engine, air from the fuel tank air space flows counter to fuel returning to the fuel tank by gravity, to maintain the space vacated by returning fuel near atmospheric pressure.
