1. A refrigeration system of a building, comprising: a compressor module configured to, in response to a determination that an amount of a refrigerant of the refrigeration system that is present outside of the refrigeration system within the building is greater than a first predetermined amount, maintain a compressor of the refrigeration system off continuously for at least a predetermined period; and
a fan module configured to, in response to the determination that the amount of the refrigerant that is present outside of the refrigeration system within the building is greater than the first predetermined amount, maintain a fan on continuously for at least the predetermined period, wherein the fan moves air across an evaporator of the refrigeration system when the fan is on, and wherein the compressor module is further configured to: without receiving input indicative of a reset of the refrigeration system, after the compressor has been off for the predetermined period and the amount of refrigerant that is present outside of the refrigeration system within the building is less than a second predetermined amount, automatically turn the compressor on; and after a predetermined number of refrigerant leak events occur, disable the refrigeration system until user input indicative of a manual reset is received.
