• Evaporator, Compressor, Condenser, Metering Device

• Metering Device, Filter Drier, Reversing Valve, Condenser

What type of oil is used in R-410A refrigerant systems?

• Mineral Oil

• Alkylbenzenes Oil

• POE Oil

Why do Heat Pump systems need the refrigerant in the first place?

• To heat a home during summer and cool during th winter

• To heat in the winter and cool in the summer

What does the Filter Drier do in a Cooling System?

• Meter the amount of refrigerant flowing to the Evaporator

• Catches all dirt in the system flowing to the Metering Device

• Makes the refrigerant a different temperature

What does the Compressor do in a Cooling System?

• Cools the gas down into a liquid

• Makes the refrigerant a heated vapor

• Turns it from a liquid to a vaporr

What refrigerant is most used in Cooling Systems today?

• R-22

• R-134A

• R-1234YF

• R-410A

Why is there a reversing valve in a Heating And AC System?

• To break the Compressor

• To switch between Heating and Cooling

• To defrost the coil when it freezes over

Which was does the Refrigeration Cycle flow?

• Clockwise

• Counterclockwise

What does the Evaporator do in a Cooling System?

• Turns the Refrigerant into a liquid

• Turns the refrigerant into a vapor

• Absorbs cold air into the refrigerant

• Absorbs hot air into the refrigerant

What is the most common Compressor used today in Residential AC and heat Pumps?

• Reciprocating Compressor

• Rotary Compressor

• Scroll Compressor

• Screw Compressor
