摘要： When during a first action of a refrigeration system the internal cold storage temperature is held at a desired temperature by an evaporator, the refrigeration system performs a second action of increasing the cooling capacity of the evaporator to decrease the internal cold storage temperature. When during the second action the internal cold storage temperature reaches a minimum temperature Tmin, the refrigeration system stops a compressor and performs a third action. When during the third action the internal cold storage temperature reaches a maximum temperature Tmin, the refrigeration system drives the compressor and performs the first action.

摘要： A control algorithm is developed which takes corrective action in the event that system conditions indicate there may be an inadequate flow of lubricant in the system. In particular, if a discharge pressure is below a predetermined amount or if the suction modulation valve is throttled, there is a possibility of inadequate lubricant flow. The system control then turns off the condenser fan, and if that first step is not sufficient, may also turn on an evaporator heater and then control a suction modulation valve. A fail safe control loop also takes effect if the condition sensor appears to have failed.

摘要： A cooling system controller (60) controls the capacity of a variable capacity compressor (44/244a-d) based upon the temperature of a housing being cooled, the suction pressure of the compressor or both of these criteria. The cooling system controller is capable of controlling either single-evaporator (54/254) or multiple-evaporator (54a,54,54c) refrigeration systems. The multiple-evaporator systems can have evaporators of similar temperatures or of mixed temperatures. The controller (60) also allows the use of one or more condenser fans (202,204) that are operated in a lead/lag fashion to control the cooling capability of the system.

The lead compressor is in a tandem set of scroll compressors of a cooling system. The tandem set of compressors comprises a lag compressor. The method further includes: activating the lead compressor when the cooling value is greater than the activation point; activating the lag compressor subsequent to activating the lead compressor; and determining whether conditions exist including: an alarm associated with the lag compressor being generated, and the lead compressor being deactivated. The method further includes deactivating the lag compressor when at least one of the conditions exists in the cooling system.
