    摘要： The invention discloses a controller for a vapour compression system for cooling a refrigerated space. The system comprises a circuit for circulation of a refrigerant between a compressor, a condenser, and an evaporator. An expansion valve controls a flow of the refrigerant into the evaporator and thereby cooling of the refrigerated space. The control system is adapted to control the expansion valve based on a first temperature in the circuit between the evaporator and the compressor and a second temperature determined in the refrigerated space.

    摘要： A refrigeration system including a condenser having a condenser inlet and a condenser outlet, a compressor fluidly connected to the condenser inlet, and an evaporator including an evaporator inlet and an evaporator outlet. The evaporator outlet is fluidly connected to the compressor. A compressor speed sensor senses an operational speed of the compressor. An electric expansion valve (EEV) is fluidly connected to the condenser outlet and the evaporator inlet. The EEV includes a valve member that is selectively positioned to establish a desired opening to pass refrigerant from the condenser to the evaporator. A controller is electrically connected to the EEV and the compressor speed sensor. The controller establishes the desired opening of the valve member based on one of a cooling mode superheat value and a heating mode super heat value, and the operational speed of the compressor.
