Abstract (en)

[origin: EP0893663A1] A method (200) of controlling the defrosting cycles of a battery in a heat-pump system, comprising the steps of detecting (207) a first value indicative of a state parameter relating to a refrigerant fluid used in the system, comparing (239) the first value with a threshold value, and performing (245) a defrosting cycle in dependence on a result of the comparison, includes the steps of determining (221-227) a second value correlated with a maximum value of the first value and modifying (230) the threshold value in dependence on the second value. <IMAGE>
