    Abstract: A method for controlling a refrigeration system comprising a variable compressor capacity, and at least two refrigeration entities 4, e.g. display cases. Suction pressure is controlled by means of permitting/preventing a flow of refrigerant into evaporator of one or more refrigeration entities 4. Compressor capacity is controlled to match a desired capacity level and based on a signal derived from one or more properties of the one or more refrigeration entities 4, said signal reflecting a possible difference between the current compressor capacity and a current refrigeration demand of the refrigeration system. Reduces wear on compressors because switching them ON/OFF is avoided to the largest extent possible. Prevents problems relating to conflicting control strategies due to control parameters, e.g. suction pressure, being controlled by means of two or more controllable parts, e.g. compressors and flow of refrigerant into refrigeration entities.

    Abstract: A control system is provided for generating discrete stepped output capacities in a refrigeration system (100). The refrigeration system (100) is preferably a multi-evaporator system having two or more multi-capacity compressors (102, 104). The multi-capacity compressors (102, 104) can be any kind of reciprocating compressor or scroll compressor that can provide two or more different output capacities. The contributions of the compressors (102, 104) to the overall system capacity can be equal, or more preferably, they can be unequal, i.e., one compressor provides more capacity than the other compressor(s). The control system generates the stepped capacities of the refrigeration system (100) by configuring and controlling the operation of the compressors (102, 104) and the output capacity provided by the compressors (102, 104).

    Abstract: A cooling system (10) including an evaporator (28), a suction line (74), a two stage compressor (20), a gas cooler (24) and a capillary tube (60). The suction line receives gaseous or two phase refrigerant from the evaporator, the compressor receives the gaseous or two phase refrigerant from the suction line, and the gas cooler cools compressed refrigerant discharged from the compressor. The capillary tube carries refrigerant from the gas cooler to the evaporator, and the suction line may include two straight portions with two portions of the capillary tube helically wound there around, with a bypass valve (24) around the capillary tube, and an accumulator between the suction line portions. An inter-cooler (38) is between stages of the compressor, and a pan collects water condensate from the air side of the evaporator, and the refrigerant tube carries cooled refrigerant from the gas cooler through the pan. A controller (92) selectively turns the compressor on and off based on temperature or pressure sensed by a sensor (94).

    Abstract: A refrigerator that efficiently cools multiple cold spaces at different temperatures with one compressor and one condenser is disclosed. Multiple, fan equipped evaporators (EVAP1, EVAP2, EVAP3) are in series, and an expansion valve (EV) regulates superheat from inlet to outlet of the series evaporators (EVAP1, EVAP2, EVAP3). Cold space temperatures (T1, T2, T3) are regulated with an on-off thermostat in each space. If only one fan (F1, F2, F3) is turned on, system performance approaches that of a single evaporator refrigerator with controlled superheat. More than one evaporator fan (F1, F2, F3) may be turned on for initial cooldown.
