Verified Answers |Latest Update| Already Graded A+
LEED STANDS FOR ✔Correct Answer-LEADERSHIP ENERGY ENVIRONMENT DESIGN
WHO AND WHAT IS ASHRAE ✔Correct Answer-The American Society of Heating, Refrigerating
and Air-Conditioning Engineers
Common HVAC Fuel Type Options: ✔Correct Answer-1. Electric,
2. Natural Gas
3. Propane,
4. Fuel Oil/Kerosene (Diesel Fuel)
5. Wood,
6. Solar (not a stand alone option)
7. Biomass...etc (not typical)
Common Heating System Choices: ✔Correct Answer-1. Electric Strip: Uses either baseboard or air
handler mounted electric resistance strips. -Low installation cost but least efficient option.
2. Heat Pump: Air conditioner refrigeration cycle in reverse (heats home instead of cooling it). Cost
effective vs. electric strip in all regions except very warm.
3. Gas Furnace: -Burns natural gas or liquid propane
Types of Heat Pumps: ✔Correct Answer-1. Air-To-Air
2. Water source
3. Geothermal
HVAC: ✔Correct Answer-Heating, Ventilation and Air Conditioning
AHU: ✔Correct Answer-Air Handling Unit
CFM: ✔Correct Answer-Cubic Feet per Minute of Air Flow
NACH: ✔Correct Answer-Natural Air Changes Per Hour
Ceiling Fan Direction vs Season ✔Correct Answer-During the Summer: Fans should blow DOWN
During Winter: Fans should blow UP
Two types of cooling an air-conditioner performs: ✔Correct Answer-1. Latent Cooling (de-
humidification)
2. Sensible Cooling (refrigerant turns to gas)
What does SHGC stand for? ✔Correct Answer-Solar Heat Gain Coefficient, how much heat passes
through a window
What is the SHGC for North Carolina? ✔Correct Answer-0.3
What are the 4 variables that determine the efficiency of a building? ✔Correct Answer-Volume
Insulation (r-value)
, Location
Temperature Set Point
What are the temperature set points for winter and summer? ✔Correct Answer-Winter - 72
degrees F
Summer - 75 degrees F
How many BTUs are one ton of cooling? ✔Correct Answer-12,000 Btu
The smaller the total cooling load... ✔Correct Answer-the more efficient the building
How are HVAC systems sized? ✔Correct Answer-By the ton
4 Modes of Heat Transfer ✔Correct Answer-Conduction
Convection
Radiation
Evaporation
What is the main difference between a furnace and a boiler? ✔Correct Answer-Furnace heats air,
Boiler heats water
Radiant heat systems use which type of fuel? ✔Correct Answer-All fuel types
Which refrigerant lines are hot and cold ✔Correct Answer-Low pressure gas is cold
Condensing coil is hot
A split system is what ✔Correct Answer-A system with a unit outside and a unit inside connected
by refrigerate lines
BTU= ✔Correct Answer-1 pound per 1 degree F
A heat pump uses what mode of heat transfer ✔Correct Answer-Convection
What is the bulk cost of a heat pump ✔Correct Answer-burying the loop
Heat loss or gain is driven by what dynamic ✔Correct Answer-difference in temperature (ΔT)
What is the software used to determine the heating and cooling loads? ✔Correct Answer-Manual
J
The electric baseboard is often chosen because of which factor ✔Correct Answer-cheapest to
install
What is the min. SEER central air conditioner manufactured today? ✔Correct Answer-13
COP to HSPF ✔Correct Answer-multiply by 3.4
COP of 2 = HSPF of ?? ✔Correct Answer-HSPF of 6.8
HSPF --> COP ✔Correct Answer-divide by 3.4
