Title:
REFRIGERATOR
Document Type and Number:
Japanese Patent JP2017150753
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a refrigerator that can suppress an increase in viscosity resistance in a sliding portion of a compressor and can improve performance.SOLUTION: A refrigerator includes a refrigeration cycle in which a compressor, a condenser, an expansion mechanism and an evaporator are connected annularly. In the refrigerator, a condensation temperature may reach 46°C or higher. The condensation temperature is a temperature that causes a refrigerant circulating in the refrigeration cycle to be condensed. Refrigerating machine oil for lubricating the compressor is filled in the refrigeration cycle. The refrigerating machine oil is oil of which separation temperature is higher than the condensation temperature. The separation temperature is a temperature that causes a mixture of the refrigerating machine oil and the refrigerant to be separated into the refrigerating machine oil and the refrigerant. Since the separation temperature is higher than the condensation temperature, separation of the refrigerant circulating in the refrigeration cycle from the refrigerating machine oil is suppressed.SELECTED DRAWING: Figure 1
