PROBLEM TO BE SOLVED: To provide a refrigerant leakage detection system and a refrigerant leakage detection method capable of detecting refrigerant leakage precisely and rapidly.SOLUTION: A refrigerant leakage detection system includes an outside temperature measuring part 2a for measuring an outside temperature of cooling instrument 2, a high pressure measuring part 3b for measuring a high pressure of a refrigerator 3 for supplying refrigerant to the cooling instrument 2, a low pressure measuring part 3c for measuring a low pressure of the refrigerator 3, a correlation calculating part 8a for getting a correlation between an outside temperature measured by the outside temperature measuring part 2a and a high pressure measured by the high pressure measuring part 3b, a pressure estimating part 8b for estimating the high pressure of the refrigerator 3 in reference to the outside temperature measured by the outside temperature estimating part 2a on the basis of the correlation got by the correlation calculating part 8a, and a refrigerant leakage determination part 8c for comparing the high pressure estimated by the pressure estimating part 8b with the high pressure measured by the high pressure measuring part 3b so as to determine presence or absence of leakage of refrigerant.SELECTED DRAWING: Figure 1 |
