Abstract

Method and device to control refrigeration conditions in refrigerated showcases, modules (10) or similar, said refrigerated modules comprising at least a front glass (11), a refrigerated compartment, a cooling circuit (17), antimisting devices (32) and a cooling assembly (40), it being provided, during functioning, to measure at least the values of temperature of the air (21) entering and leaving the evaporator unit (13), to compare them with pre-determined threshold values and to give permission to start a defrosting cycle to defrost the evaporator unit (13) only when the continuously measured values reach the threshold values.
