摘要： A calculating section (103) calculates a target COP that is a maximum COP that the centrifugal chiller can achieve using an arithmetic expression in which an actual device loss is given as a correction term to an expression that represents a COP characteristic under an ideal lossless environment. Since the arithmetic expression for calculating the target COP includes the heat exchange loss of the evaporator as a correction term, the heat exchange loss being calculated using a function having a load factor as a parameter, the heat exchange loss of the evaporator is reflected in the target COP.

摘要： An object is to sequentially calculate planned COPs. Provided is a performance evaluation device for a variable-speed centrifugal chiller that includes a data acquisition unit that acquires operating data of the variable-speed centrifugal chiller as input data; a storage unit that stores a first arithmetic equation derived on the basis of mechanical characteristics of the chiller and used for calculating a relative load factor that relatively expresses a relationship between a current load factor at a current coolant inlet temperature and a predetermined load factor at a predetermined coolant inlet temperature set as a reference operating point, a second arithmetic equation that expresses a relationship between the relative load factor and a correction coefficient, aid a third arithmetic equation used for calculating a planned COP by using the correction coefficient to correct a COP calculation equation derived from a reverse Carnot cycle; and an arithmetic unit that calculates the planned COP under current operating conditions by using the operating data acquired by the data acquisition unit in the first, second, and third arithmetic equations stored in the storage unit.

摘要： A refrigerant system is provided with a suction pulse width modulation valve, and a pulse width modulation control for controlling this valve. System pressures, such as the pressure on the evaporator and the condenser are monitored. The measured system pressures are maintained within a band of acceptable lower and upper limits. As the pulse width modulation control cycles the valve, the refrigerant pressures in the evaporator and the condenser tend to fluctuate. The control ensures those fluctuations are within the limits by controlling the duty cycle of the valve.

摘要： Es wird ein Verfahren zum Steuern einer Kälteanlage vorgesehen, welches ein Kältemittel, einen Verdampfer, einen Verdichter, einen Verflüssiger und ein elektronisch ansteuerbares Drosselorgan aufweist. Es erfolgt ein Umschalten von einer normalen Betriebsart in eine Kalibrier-Betriebsart. Weiterhin werden durch Anfahren eines speziellen Betriebszustandes, in dem sich eine bekannte physikalische Abhängigkeit zwischen Prozesswerten des Kältekreises zumindest annähernd einstellt, die jeweiligen Prozesswerte erfasst. Kalibrierwerte werden gebildet zum Beschreiben eines Fehlereinflusses auf Teile der Kälteanlage basierend auf den erfassten Prozesswerten. Basierend auf den Kalibrierwerten wird mindestens ein Korrekturwert ermittelt und zur normalen Betriebsart zurückgekehrt. Weiterhin wird eine Kälteanlage beschrieben, die zum Auslösen einer Kalibrierung eine Kalibrierauslöseeinheit sowie eine Anlaufsteuereinheit zum Anfahren eines speziellen Betriebszustandes der Kälteanlage aufweist. Mit Hilfe einer Recheneinheit werden Kalibriergrößen zur Beschreibung eines Fehlereinflusses auf Teile der Kälteanlage ermittelt und mit einer Korrektureinheit mindestens ein Korrekturwert basierend auf den ermittelten Kalibrierwerten gebildet.
