Abstract
A refrigeration apparatus includes a housing, a refrigerant circuit, a utilization power source, a ground line, and a grounding resistor. The refrigerant circuit circulates a refrigerant that is subject to potential disproportionation reaction. The utilization power source receives electrical power from a commercial power source. The ground line electrically connects the housing to an external ground. The grounding resistor is electrically connected to the ground line, and has a resistance equal to or more than 0.1Ω.
