Abstract: A control for a refrigeration system serviced by a special pulse width modulated compressor (30) coupled to a condenser (32)and evaporator (42). The system can be of the distributed type wherein the condenser (32) and compressor (30) may be coupled to service a group of adjacent refrigeration cases, wherein each case would have its own evaporator (42). A controller (52) is coupled to a load sensor (58) for producing a variable duty cycle control signal (54) in which the duty cycle is a function of demand for cooling. Moreover, fuzzy logic technique may be utilized in order to provide self adaptive tuning control for the system.

Abstract: A scroll compressor includes a capacity modulation system. The capacity modulation system has a piston that is connected to the non-orbiting scroll that disengages the non-orbiting scroll from the orbiting scroll when a pressure chamber is placed in communication with the suction chamber of the compressor. The non-orbiting scroll member moves into engagement with the orbiting scroll when the chamber is placed in communication with the discharge chamber. The engagement between the two scrolls is broken when the pressure chamber is placed in communication with fluid from the suction chamber. A solenoid valve controls the communication between the pressure chamber and the suction chamber. By operating the valve in a pulsed width modulated mode, the capacity of the compressor can be infinitely varied between zero and one hundred percent.
