Refrigeration Cycle
Does heat flow from:
-High to low temperature
-Low to high temperature
High to low!!!
What is the main purpose of the condenser?
To condense the refrigerant vapor and rejects the heat from the cycle!
What evaporates in the evaporator?
Refrigerant!
What is the main purpose of a TXV?
Name Chinami and Nathan's title, major, and university.
-Technical Sales Interns
-Industrial Distribution Major
-Texas A&M University
Which component is responsible for increasing both pressure and temperature of the refrigerant?
Compressor!
In a water-cooled system, what auxiliary equipment often pairs with a condenser to maintain performance?
Cooling Tower!
What is the main purpose of the fins on a tube-finned evaporator?
What are the dangers of too much and too little superheat?
Too little:
-risk of damage to compressor by liquid refrigerant
Too much (compressor and evaporator risks):
- Potential coil frosting in the evaporator
-Risk of compressor damage due to overheating
In March a funeral was held outside the American Airlines Center, who was it for?
Luka Doncic!
In which component does the refrigerant release latent heat?
Condenser!
What is the main advantage of centrifugal air-cooled condensers?
Centrifugals meet higher static pressure demands!
What type of Evaporator are used in industrial applications (manufacturing plants) and why?
Shell and tube, because they are serviceable!
-Return oil to the compressor
-Ensure that only liquid refrigerant enters the expansion device
-Minimize system capacity loss
-Minimize refrigerant charge
Which celebrity rented out the entire city for their wedding and what city was it?
Jeff Bezos in Venice, Italy
Name all the refrigeration components in order.
(Starting in any order)
Compressor, Condenser, Expansion Valve, Evaporator!
What differentiates an air-cooled condenser and an evaporative condenser?
The evaporative condenser sprays water on top of the refrigerant tubes as air is drawn over them (thus evaporating the water).
What does superheating the vapor accomplish at the evaporator?
Ensures the refrigerant is completely a vapor before it returns to the compressor!
What is at the end of a capillary tube?
Two fathers and two sons are in a car, yet there are only three people in the car. How is this possible?
Answer: They are grandfather, father, and son
How many Btus does it take to boil a pound of water?
970.3!
Refrigerant leaves the condenser at (blank) temperature, (blank) pressure and (blank) state.
Refrigerant enters the condenser at (blank) temperature, (blank) pressure and (blank) state.
Leaves:
-low temperature
-high pressure
-liquid
Enters:
-high temperature
-high temperature
-gas
What component within a shell and tube evaporator, increases the surface area, inducing turbulence and improves heat transfer?
Baffles!
What three components are inside the TXV?
-Valve diaphragm
-Valve pin
-Spring
What Number Am I thinking of 1-5
2!
