Hydronic Heating and Cooling Pretest/Post-test Questions with Correct Answers

Hydronic Heating and Cooling Pretest/Post-test Questions with Correct Answers T/F Forced-air systems cost less than hydronic systems to operate and maintain because of the durability and long life of the equipment - Correct Answer False T/F Far less water than air is needed to distribute the same amount of heat, meaning that hydronic water distribution can use piping that is much smaller than the equivalent air ductwork. - Correct Answer True T/F For practical purposes, enthalpy may be taken as the sum of sensible heat and latent heat. - Correct Answer True T/F Heat transfer is the flow of heat from one object or substance to another, and it occurs because of a difference in pressure. - Correct Answer False T/F Single-wall heat exchangers are less efficient than double-wall heat exchangers of equal size. - Correct Answer False T/F The compressor pumps the vaporized refrigerant away from the evaporator and discharges it at a higher pressure and temperature into the condenser. - Correct Answer True T/F
