Intro to Hvac
This does HVACR stand for?
What is Heating, Ventilation, Air Conditioning, and Refrigeration.
This measures the flow of electrons in a circuit.
What is current?
This device burns gas to heat air in homes
What is a furnace?
This coil absorbs heat from inside the building.
What is the evaporator coil?
This process joins metals using filler metal at lower temperatures than brazing.
What is soldering?
This controls temperature in a building.
What is a thermostat?
This unit measures electrical pressure.
What is volts?
This system heats water or steam for a building.
What is a boiler?
This component pumps refrigerant through the system.
What is a compressor?
This process joins metals using a higher temperature than soldering.
What is brazing?
This part of HVAC removes dust, pollen, and other particles from the air
What is an air filter?
This law states voltage = current × resistance.
What is Ohm’s Law?
This part blows warm air through ducts.
What is a blower Motor?
This device controls refrigerant flow into the evaporator.
What is a metering device?
This is used to clean metal before joining in soldering or brazing.
What is flux?
This is the main purpose of an HVAC system.
What is to provide comfort and maintain indoor air quality?
This device protects a circuit from too much current.
What is a circuit breaker?
This device starts the flame in a gas furnace.
What is an igniter?
This coil releases heat to the outside air.
What is the condenser coil?
This safety equipment protects your eyes during soldering or brazing
What are safety goggles?
This refers to moisture in the air.
What is humidity?
This measures resistance in a circuit.
What is ohms?
This safety device shuts off gas if the flame goes out
What is a flame sensor?
This happens if airflow is blocked or refrigerant is low, causing the evaporator to freeze.
What is coil freezing?
This tool provides a steady flame for soldering or brazing copper tubing.
What is a torch?
