摘要： A method includes operating a compressor with a vapor injection system and selectively supplying vapor to the compressor during compressor operation through actuation of a first control valve. The method further includes closing the first control valve to prevent vapor from entering the compressor for a first predetermined time period leading up to stopping operation of the compressor and stopping the compressor with the first control valve in the closed position. The compressor is started with the first control valve in the closed position and the first control valve is maintained in the closed position for a second predetermined time period following starting of the compressor. The first control valve is opened to supply vapor to the compressor after the second predetermined time period.

摘要： A method includes operating a compressor of a heat pump system and is selectively providing vapor to a vapor injection port of the compressor via a vapor injection line and vapor injection valve. The method further includes determining a frost condition of a first and second heat exchanger of the heat pump system and closing a vapor injection valve to prevent fluid flow into the compressor at the vapor injection port. A direction of refrigerant flow is reversed to direct vaporized refrigerant to the one of said first and second heat exchangers experiencing the frost condition. The vapor injection valve is opened after a first predetermined time period following reversal of the refrigerant flow. The method further includes closing the vapor injection valve and reversing a direction of refrigerant flow within the heat pump system once the vapor injection valve is closed for a second predetermined time period.

摘要： A method and controller for a refrigerant pressure effecting component of a cooling system includes providing closed loop control over a pressure effecting component based on an error signal, performing a control algorithm that includes at least one programmably adjustable gain factor, and adaptably changing the programmably adjustable gain factor by periodically generating a new gain factor. More specifically, the system and method includes monitoring fluctuation in the error signal and generating a numeric value indicative of the percent fluctuation in the error signal over a predetermined period of time, then fuzzifying a numeric value to generate a set of fuzzy input values. A predetermined set of rules are applied to the fuzzy input values to generate a set of fuzzy output values, which are then defuzzified by a combining operation to yield the new gain factor.

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

摘要： A diagnostic system and method for a cooling system includes producing a control signal for adjusting a valve position of a regulator valve as a demand for cooling, as well as providing an ambient temperature measurement, coil inlet temperature measurement, and coil exit temperature measurement. The valve position and at least one of the ambient temperature measurement, coil inlet temperature measurement, and coil exit temperature measurement are monitored and compared with at least one predetermined fault value indicative of a fault condition to diagnose the system. An alert module responsive to the diagnostic module issues an alert signal when at least one of the ambient temperature measurement, coil inlet temperature measurement, and coil exit temperature measurement bears a predetermined relationship to the fault value. When monitoring and comparing, an error value percentage indicative of a percentage of sampled error within an accepted offset range for a defined period of time is determined.
