Abstract
A refrigeration cycle state predicting device according to the present disclosed technique is a refrigeration cycle state predictor constituting a refrigeration cycle device, and includes a predictor to calculate a prediction value of a future state of the refrigeration cycle device on the basis of an input provisional operation amount array.
Claims
exact text as granted — not AI-modified1 . A refrigeration cycle controller constituting a refrigeration cycle device, wherein,
the refrigeration cycle device includes a plurality of indoor equipments having different refrigerant systems in the same room, or includes an indoor equipment having a plurality of heat exchangers having different refrigerant systems, the refrigeration cycle controller comprising: an operation amount calculator to calculate a provisional operation amount array by calculation in such a manner as to satisfy a constraint condition; and a refrigeration cycle state predictor including a predictor to calculate a prediction value in a future state of the refrigeration cycle device by referring to the input provisional operation amount array, wherein, the operation amount calculator includes, an evaluator to calculate a value of an evaluation function used to calculate the provisional operation amount array, and an optimization calculator to obtain a solution of the provisional operation amount array minimizing the value of the evaluation function, and wherein, the evaluation function includes the following penalty term (V p ),

2 . A refrigeration cycle controller constituting a refrigeration cycle device, wherein,
the refrigeration cycle device includes a plurality of indoor equipments having different refrigerant systems in the same room, or includes an indoor equipment having a plurality of heat exchangers having different refrigerant systems, the refrigeration cycle controller comprising: an operation amount calculator to calculate a provisional operation amount array by calculation in such a manner as to satisfy a constraint condition; and a refrigeration cycle state predictor including a predictor to calculate a prediction value in a future state of the refrigeration cycle device by referring to the input provisional operation amount array, wherein, the operation amount calculator executes the following operation of, (a) provisionally generates a provisional operation amount array indicating that all the refrigerant systems are in a normal operation mode at all times; (b) initializes a defrosting operable time (t d ); (c) by defining a set R d being the set of refrigerant systems in which the amount of frost is estimated not to exceed the upper limit of the amount of frost (F n ), checks whether or not R d is an empty set, and,
if R d is an empty set, the processing operation is ended, and if R d is not an empty set, the processing operation proceeds to operation (d);
(d) determines the period during which the defrosting operation is to be performed for a refrigerant system having the slowest time at which a frosting amount exceeds the frosting amount upper limit value (F n ) among the refrigerant systems included in R d ;
(e) updates the defrosting operable time (t d ) and updates R d .
