Total questions: 10
Worksheet time: 5mins
Why is it important to know what factors impact the heat load of a home?
to select the proper air duct materials and fittings
to select the appropriate HVAC equipment
to select and locate grilles, registers and diffusers
to select the appropriate building material for a home
A higher number of occupants in a home can______.
decrease delta T of a home
increase the heat loss of a home
increase the heat gain of a home
decrease the amount of infiltration in a home
Heat load is
the amount of heat a building needs to maintain the indoor temperature at the desired levels
the amount of sensible heat that must be removed by the air conditioning equipment in a building
the amount of heating and cooling the equipment can withhold in order to maintain the design temperature at the desired levels
the input BTU rating of the HVAC equipment
Which one of the following factors can impact both the heat gain and heat loss of a building?
electric appliances, the number of occupants, building materials and the level of insulation used.
the type of furniture used with the building
the orientation of windows and skylights
the coloring of appliances and the ductwork uded in the home
Which design temperature includes both sensible and latent heat?
indoor temperatures
winter design temperatures
summer design temperatures
delta T temperatures
Which three categories include factors that need to be considered when calculating the heating and cooling load of a home?
climate, design conditions, and building details
building orientation, climate, and home occupants
insulation, building design, and appliances
outdoor relative humidity
What is the typical indoor design temperature during summer?
68 degrees Fahrenheit
75 degrees Fahrenheit and 50% relative humity
60 degrees Fahrenheit

Manual J Calculations should only be used for
Commercial applications
Residential applications
outdoor patio applications
solarium applications
Which of the following is not a benefit of having a properly sized HVAC system
less wear and tear on the HVAC equipment
better humidity control which prevents mold growth
a greater temperature difference between rooms in their homes
can provide greater comfort for occupants in the home
What is the purpose of performing a heat load calculation according to manual J.
provides standards and protocols to determine the amount of insulation needed in a home and the equipment needed to install this insulation
provide standards and protocols for the proper selection of grilles, registers and diffusers
provides standards and protocols to determine the amount of heating and cooling a home needs in order to select the appropriate sized HVAC equipment
provides the standards and protocols to determine the amount of ductwork needed in a home and the equipment needed to install the ductwork
