, 1: What is the primary function of a refrigeration system?
The primary function of a refrigeration system is to remove heat from a
designated area and discharge it elsewhere, thereby cooling the area to the
desired temperature.
2: Which law of thermodynamics is fundamental to refrigeration processes?
The second law of thermodynamics is fundamental to refrigeration processes,
as it explains how heat can be transferred from a cooler to a warmer body
using work.
3: What is the role of the evaporator in a refrigeration system?
The role of the evaporator is to absorb heat from the environment or space to
be cooled, causing the refrigerant inside to evaporate and remove heat from
the surroundings.
4: How does a compressor function within a refrigeration cycle?
A compressor functions by compressing the refrigerant vapor, increasing its
pressure and temperature, and pushing it through the system to the
condenser.
5: What is the purpose of the condenser in a refrigeration system?
The purpose of the condenser is to release absorbed heat from the refrigerant
to the outside environment, condensing it back into a liquid state.
6: Define superheating in the context of refrigeration.
Superheating refers to the process of increasing the temperature of the
refrigerant vapor above its saturation point after it has evaporated in the
evaporator.
7: What is subcooling, and why is it important?
Subcooling is the process of cooling the refrigerant liquid below its saturation
temperature after it has condensed, ensuring that only liquid refrigerant enters
the expansion valve.
