Abrégé
(EN)

PROBLEM TO BE SOLVED: To accurately determine the propriety of an amount of a refrigerant filled in an air conditioner, even when the amounts of the refrigerant filled in a site are dispersed, or even when a reference value of an operation state amount used for determining the propriety of the amount of the refrigerant is fluctuated by a difference in a piping length of a refrigerant communication pipe, combination of used units, or an installation height difference between the respective units, in the multitype air conditioner.

SOLUTION: This system of determining the refrigerant amount determines the propriety of the amount of the refrigerant in the air conditioner 1 provided with a refrigerant circuit 10 connected with a heat source unit 2 and the used units 4, 5 via the refrigerant communication pipes 6, 7, and is provided with a state amount accumulation means and a refrigerant amount determination means. The state amount accumulation means accumulates the operation state amounts of the refrigerant flowing in the refrigerant circuit 10 filled with the refrigerant up to an initial refrigerant amount by filling the refrigerant at the site, or of constitutive components. The refrigerant amount determination means compares a current value of the operation state amount with a reference value that is the operation state amount obtained at a test operation, and determines the propriety of the amount of the refrigerant.

【課題】マルチタイプの空気調和装置において、現地において充填された冷媒量にばらつきが生じたり、冷媒連絡配管の配管長さ、利用ユニットの組み合わせや各ユニット間の設置高低差よって冷媒量の適否の判定に使用される運転状態量の基準値に変動が生じる場合であっても、装置内に充填されている冷媒量の適否を精度よく判定する。
【解決手段】冷媒量判定システムは、熱源ユニット2と利用ユニット4、5とが冷媒連絡配管6、7を介して接続されて構成される冷媒回路10を備えた空気調和装置1において、冷媒量の適否を判定するものであり、状態量蓄積手段と、冷媒量判定手段とを備えている。状態量蓄積手段は、現地における冷媒充填によって初期冷媒量まで冷媒が充填された冷媒回路10を流れる冷媒又は構成機器の運転状態量を蓄積する。冷媒量判定手段は、試運転時における運転状態量を基準値として、運転状態量の現在値と比較して、冷媒量の適否を判定する。
