METHOD OF INSTALLING REFRIGERATOR AND HEATING HEATER

摘要

PROBLEM TO BE SOLVED: To solve such inconvenience that there are possibilities of causing the breakdown of a refrigerator due to the fact that a defrosting heater becomes a source of ignition in the case when refrigerant leak from a refrigerating cycle is caused in the case of the refrigerator using combustible refrigerant for refrigeration. SOLUTION: In the refrigerator using combustible refrigerant for refrigeration, there are provided a cooler cooling down the cold air circulating inside the refrigerator body, and the defrosting heater installed in the vicinity of the cooler and comprising the container body having a heating element inside and an opening part with at least a part opened to defrost the cooler. The defrosting heater is installed in such a manner that the opening direction of the opening part to the ascending direction of the ascending flow of natural convection generated in the container body by allowing the heating element to generate heat is within a predetermined angle range making it hard for the gas in the periphery of the container body to flow into the container body.
