Title:
冷媒漏洩検知システム
Document Type and Number:
Japanese Patent JP7197814
Kind Code:
B2
Abstract:
If refrigerant leakage is detected by only one method, the detection accuracy is not sufficient. A refrigerant leakage detection system (1) is a system for a refrigeration cycle device (100) having a refrigerant circuit (11). The refrigerant leakage detection system (1) includes a first control unit (10), a second control unit (20), and a third control unit (30). The first control unit (10) uses a first method to determine the presence or absence of refrigerant leakage from the refrigerant circuit (11). The second control unit (20) uses a second method different from the first method to determine the presence or absence of refrigerant leakage from the refrigerant circuit (11). The third control unit (30) determines the presence or absence of refrigerant leakage from the refrigerant circuit (11) on the basis of the determination result of the first control unit (10) and the determination result of the second control unit (20). The third control unit (30) determines that there is a refrigerant leakage in the refrigerant circuit (11) if the first control unit (10) determines that there is a refrigerant leakage from the refrigerant circuit (11) and the second control unit (20) determines that there is a refrigerant leakage from the refrigerant circuit (11).
