  • Direct drive multi-temperature special evaporators
    Patent number: 6804972
    Abstract: A system and method for controlling the climate within a storage container including at least two cargo areas. The system includes one compressor, one condenser, and two evaporators. Each of the evaporators includes a crankcase pressure regulator, a gas valve and a liquid valve. The crankcase pressure regulators provide a common pressure between each of the evaporators and the compressor regardless of the pressure at the evaporator. A control system selectively actuates the gas and liquid valves according to a predefined control mode to obtain and maintain a desired temperature.
