    摘要： A frozen product dispenser is characterized by at least two product freeze barrels for receiving product therein and for freezing the product for dispensing, and a refrigeration system for chilling the at least two barrels. The refrigeration system has at least two evaporators for and heat transfer coupled to each barrel, separate and controllable expansion valves each having an outlet coupled to an inlet to an inlet to an associated one of the evaporators, at least two compressors having outlets coupled to inlets to the expansion valves and inlets coupled to outlets from the evaporators, and at least one condenser in fluid circuit between outlets from the compressors and inlets to the expansion valves. The refrigeration system is controllable to selectively operate one or more of the compressors and one or more of the expansion valves in accordance with the cooling requirements of the barrels to provide an improved turndown ratio for improvements in efficiency of operation of the refrigeration system in response to changing cooling load requirements of the product barrels.

    摘要： A variable capacity refrigeration system for a frozen product dispenser is controllable in response to cooling load requirements of the dispenser to have a variable cooling capacity that is in accordance with the cooling load demands placed on the refrigeration system by the dispenser. This is accomplished, in part, by providing the refrigeration system with a variable capacity compressor, the output capacity of which is controlled by varying its operating speed in a manner such that refrigerant output from the compressor generally meets the mass flow of refrigerant through expansion valves of the system. The arrangement provides for efficient operation of the frozen product dispenser from an energy standpoint and for a reduction in on/off cycling of the refrigeration system.
