B. 30°F to 35°F.
C. 35°F to 40°F.
D. 40°F to 45°F.
Expert Solution & Answer

The correct option for the given statement.
Answer to Problem 1RQ
The correct option for the given statement is option(C) i.e.
Explanation of Solution
At normal room temperature, the typical temperature inside the fresh food compartment of a domestic refrigerator is similar to the temperature of the air that is returned to the evaporator coil and typically it may be
Important terms used in domestic refrigerators:
- The single compressor in a household refrigerator operates under conditions at lowest box temperature, which is typically -10 to +5 Degrees F.
The two types of evaporators are used in household refrigerators are natural draft or force draft.
- Domestic freezers are considered as a separate compartment in a refrigerator or a separate appliance. Domestic freezers are of two types:
- Domestic refrigerator compressors are reciprocating or rotary type and welded hermetically sealed compressors are normally used in household refrigerators.
- Condensers in these refrigerators are all air cooled.
- The fresh food compartment of a domestic refrigerator represents about
(i). Upright type freezers
(ii). Chests type freezers.
