Question

One advantage of a flooded tube evaporator is that:

A) They can handle a large increase in load
B) There is less chance of loss in refrigerant
C) Less refrigerant is required
D) It requires less compress capacity

Answer 1

A flooded tube evaporator is advantageous because it requires less refrigerant, due to its design that allows for efficient heat transfer. The effectiveness increases with a smaller temperature difference in the cycle, leading to higher system efficiency.

Step-by-step explanation:

One advantage of a flooded tube evaporator in systems like refrigerators, air conditioners, and heat pumps is that less refrigerant is required (Option C). This efficiency stems from the evaporator’s design, which enables better heat transfer and more effective use of refrigerant. Flooded evaporators provide a large area for heat exchange due to the tubes being completely filled with refrigerant. This comprehensive contact allows for more efficient absorption of heat, thus utilizing a smaller amount of refrigerant effectively. Additionally, systems operate most cost-effectively for cycles with a small difference between the condensing temperature (T₁) and the evaporating temperature (To) because a smaller temperature difference typically leads to a higher Coefficient of Performance (COP), indicating a more efficient heat pump or cooling cycle.
