Exam Questions And Answers 100% Pass
Bond - answer✔short for surgery bond.It is a funded guarantee that a contractor will perform as
agreed
Carbon monoxide - answer✔A common by-product of combustion process,CO is a colorless,
tasteless,and orderless gas that is lighter than air and quite toxic. Co reacts with blood
hemoglobin to form a substance that signifcantly reduces the flow of oxygen to all parts of the
body.
Chiller - answer✔A high-volume hydronic cooling unit.
Chlorofluorocarbon (CFC) refrigerant - answer✔A class of refrigerants that contains chlorine,
fluorine, and carbon.CFC refrigerants have a very adverse effect on the environment.
Compressor - answer✔In a refrigeration system, the mechanical device that converts low-
pressure, low-temperature refrigerant gas into high-temperature refrigerant gas high-
temperature,high-pressure refrigerant gas.
Condenser - answer✔A heat exchanger that transfers heat from the refrigerant flowing inside it
to the air or water flowing over it.
Easement - answer✔A portion of a property that is set aside for public utilities of municipalities.
Evaporator - answer✔A heat exchanger that transfers heat from the air flowing over it to the
cooler refrigerant flowing through it.
Expansion Device - answer✔Also known as the liquid metering device or metering device.
Provides a pressure drop that converts the high-temperature, high-pressure liquid refrigerant
from the condenser into the low-temperature, low-pressure liquid refrigerant entering the
evaporator.
heat pump - answer✔A comfort air conditioner that is able to produce heat by reversing the
mechanical refrigeration cycle.
