7 Quiz Questions

Question 1

What is Saturation Point?

Answer 1

Where gas turns to liquid, liquid turns to gas

Question 2

Define Sub Cool

Answer 2

The Heat removed from a liquid below Saturation Point

Question 3

Define Super Heat?

Answer 3

The Heat added to a gas above its Saturation Point

Question 4

How do we find Super Heat?

Answer 4

1st convert Suction Pressure into temperature using the PT Chart, then Suction Line temperature minus the Evaporator Saturation temperature equals Super Heat

Question 5

How do we find Sub Cool?

Answer 5

1st convert Discharge Pressure into temperature using the PT Chart, then Condenser Saturation temperature minus Liquid Line temperature equals Sub Cool

Question 6

What causes Evaporator Split and how do we calculate it?

Answer 6

It happens because we absorb heat from the Return Air, it is the Return Air temperature minus the Supply Air temperature

Question 7

What causes the Condenser Split and how do we calculate it?

Answer 7

It happens because we REJECT The Heat from the Condensing Coil, Discharge Air temperature minus the Outdoor Air temperature
