HVAC Final Exam Complete Questions
And Verified Answers
\Q\.If (____________)% of the tenants are satisfied with the thermal environment, it is safe to
say that most people are satisfied (ASHRAE recommendation) - ANSWERS✔-80
\Q\.'Comfort' is a condition of mind that expresses satisfaction with the thermal environment
and is assessed by subjective evaluation. To control thermal comfort, there are six key variables
that we need to know, which are: - ANSWERS✔-Activity, Clothing, Air Temperature, Relative
Humidity, Air Speed, and Mean Radiant Temperature
\Q\.Flow through solid components by direct contact: - ANSWERS✔-Conduction
\Q\.Flow through an opening: - ANSWERS✔-Convection
\Q\.When you want to check the minimum level of insulation for your building in Michigan,
which regulation do you need to look at? - ANSWERS✔-ASHRAE 90.1
\Q\.Units for Heat Resistance: - ANSWERS✔-h ft^F/BTU
\Q\.What is the boiling temperature of water in SI and Imperial units? - ANSWERS✔-212
degrees F, 100 degrees C
, \Q\.What is the freezing temperature of water in SI and Imperial units? - ANSWERS✔-32
degrees F, 0 degrees C
\Q\.What does ASHRAE stand for? - ANSWERS✔-The American Society of Heating, Refrigerating,
and Air-conditioning Engineers
\Q\.What ASHRAE version do we use to double check insulation? - ANSWERS✔-ASHRAE 90.1
\Q\.What is Conduction? - ANSWERS✔-Energy flow through solid components by direct contact
\Q\.What is Convection? - ANSWERS✔-Energy flow through any opening
\Q\.What is Radiation? - ANSWERS✔-Energy flow through transparent objects
\Q\.(_______________) is the (hypothetical) uniform temperature of surrounding surfaces with
which the human body would exchange the same heat by radiation as occurs in an actual (non-
uniform) environment - ANSWERS✔-Mean Radiant Temperature
\Q\.The graphic representation of the relationship between gases and water vapor in the air is
called (________________) - ANSWERS✔-Psychrometric chart
\Q\.(_________________) heat losses are the result of heat passing through the material in the
building envelope (e.g., glass) or through an assembly of materials (e.g., walls, ceilings, floors,
and so forth) - ANSWERS✔-Transmission
\Q\.(_________________) heat losses relate to air leakage through the building envelope and
the energy required to heat unconditioned air that has leaked into the structure - ANSWERS✔-
Infiltration
