Problem: Thermo 19, or refrigeration cycle using R1234YF, operates between zero and 120 degrees.
Given: 0.6 pounds per cubic foot so that equals 1
Approach: Refridgerant leaves the evaporator with 20 degrees of super heat.
Calc: Usually we talk about v2's per hour but we can convert that to tons right they're both energy pre unit time.
Calc: So that could potentially be our numerator and then the denominator is the refrigeration effect which is m dot times h1 minus h...
Result: No subcooling and that is enough information for us to find h3 there's a couple of ways we could do that we could do it using the chart just the wa...
