Question

What system operating characteristics would you expect from a system that has an oversized-orifice-type-metering device?

Answer 1

• The suction pressure would be high.

• The head pressure would be low.

• The superheat and subcooling would both be low.

Step-by-step explanation:

This is because it potentially could over feed the evaporator producing high suction pressure leading to an increase in the valve's superheat and sub cooling.
