Abstract

Bir sızıntı tespit bölümü, soğutma çevriminin bir durum değişimi miktarı esasında soğutma çevriminden soğutma akışkanı sızıntısının olmadığı bir durumda genleşme valfının bir açılma derecesini öngörür. Daha sonra, sızıntı tespit bölümü, öngörülen açılma derecesi bir gerçek açılma derecesiyle karşılaştırılarak soğutma çevrimindeki soğutma akışkanı sızıntısını tespit eder.A leak detection section predicts an opening degree of the expansion valve in a situation where there is no refrigerant leakage from the refrigeration cycle based on a state change of the refrigeration cycle. The leak detection section then detects the refrigerant leakage in the refrigeration cycle by comparing the predicted opening degree with an actual opening degree.
