What is the primary function of a refrigeration system?
Correct!
Wrong!
A refrigeration system removes heat from an enclosed space to lower its temperature and maintain desired cooling conditions.
Which component in a refrigeration system is responsible for compressing the refrigerant gas?
Correct!
Wrong!
The compressor pressurizes the refrigerant gas, increasing its temperature before it enters the condenser for heat dissipation.
What happens to the refrigerant as it passes through the expansion valve?
Correct!
Wrong!
The expansion valve reduces the pressure and temperature of the refrigerant, preparing it to absorb heat in the evaporator.
Which factor is most important when selecting a refrigerant for an HVAC system?
Correct!
Wrong!
Refrigerant selection depends on efficiency, environmental impact, and compatibility with system components.
What role does the evaporator play in the refrigeration cycle?
Correct!
Wrong!
The evaporator absorbs heat from the surrounding air, allowing the refrigerant to evaporate and cool the space.
Why is it important to prevent refrigerant leaks in a cooling system?
Correct!
Wrong!
Refrigerant leaks reduce system efficiency, increase operating costs, and contribute to environmental damage, including ozone depletion and global warming.
