ABSTRACT:
A refrigeration system comprises a refrigeration cycle including a compressor of a variable capacity type for compressing a refrigerant and an evaporator for evaporating the compressed refrigerant. A driving source is connected to the compressor through a clutch movable between an engaged position and a disengaged position. A first detector detects pressure of the refrigerant evaporated by the evaporator to generate a signal. A second detector detects temperature relating to a cooling condition of the evaporator to generate a signal. A capacity control unit controls a discharge capacity of the compressor so as to cause the pressure detected by the first detector to approach an aimed pressure. A clutch control unit is operative in response to the signals from the respective first and second detectors to judge a condition of frosting on the evaporator for controlling the clutch for movement between the engaged and disengaged positions and to judge an insufficiency in quantity of the refrigerant in the refrigeration cycle for controlling the clutch for movement to the disengaged position.
