The main objective of an HVAC system is to ensure the acoustical

comfort of the occupants, may it be through heating or cooling.

• TRUE

• FALSE

COMPONENTS OF HVAC SYSTEMS:

transfers heat from the refrigerant (liquid that cools air) to the condenser

(the one who takes heat from air).

• Evaporator Coil

• Compressor

• Thermal Expansion Valve

• Air Ducts

COMPONENTS OF HVAC SYSTEMS:

circulates the air in the system.

• Ductwork:

• Vents

• Fan Motor

• Air Handler

COMPONENTS OF HVAC SYSTEMS:

Control electrical circuit timing to maximize efficiency.

• Thermostat

• Sensors

• Relays

• Condenser Coil

Common HVAC systems found in residential buildings are heating and cooling dual systems, which are made up of independent heating and cooling components managed by a traditional thermostat.

• Hybrid Split System

• Split System

• Packed Heating and Cooling

• Zoned System

The energy contained within a system that is responsible for its temperature.

• Heat Energy

• Thermal Energy

• Radiant Energy

“The transfer of heat through the horizontal movement of air”.

• CONDUCTION

• CONVECTION

• ADVERTION

• RADIATION

Exterior part of an air conditioner that is in charge of the condensation process that releases heat.

• EVAPORATORS

• COMPRESSORS

• EXPANSION VALVE

• CONDENSER

Houses all parts of the system in one metal cabinet. Often, the cabinet is either placed on a home or building’s ceiling or on a cement slab outside the home.
