ICEBREAKER (PART II: Heating. Ventilation and Refrigeration)

Heat pumps provide heat by absorbing heat energy from outside air and transferring it to an indoor unit via refrigerant 

• True

• False

Which of the following is NOT a major component of a heat pump? 

• Compressor

• Burner

• Indoor Unit

• Expansion Valve

What role does the compressor play in heat pump operation? 

• Pressurizes the refrigerant and moves it through the system 

• Pressurizes outdoor air before releasing it into the home

• Compresses the unit’s components to give it a small footprint 

• Captures particles from the air to improve indoor air quality 

Outdoor air must be below a certain temperature for a heat pump to perform effectively in heating mode. 

• True

• False

Heat pumps can be used for:

• Heating only

• Cooling only

• Heating and Cooling

• Heating and dehumidifying

Heat pumps are ideal solutions for:

• Homes with hot and cold spots 

• Home additions or renovations 

• Homes without ductwork 

• All of the options

The term ventilation means 

• The introduction of fresh air into a confined space in order to control air quality

• The cooling of air in a confined space to control the moisture content. 

• Making sure there's is no infiltration of unwanted odors.

• a requirement by LEED that air pressure stay constant, and no air changes happen over a certain period.

What component in the following list is not necessary for a refrigeration cycle? 

• Evaporator

• Metering Device

• Compressor

• Condenser

When did Peter Von Rittinger develop and build the first heat pump system? 

• 1912

• 1876

• 1856

• 1902

Occurs when the air in a space is changed with outdoor air without the use of mechanical systems, such as a fan 

• Stack Effect Ventilation

• Wind Effect Ventillation

• Mechanical Ventilation

• Natural Ventilation
