Heating, Ventilation, & Air Conditioning
These are all examples of what solar heating system?
Direct gain
Indirect gain
isolated gain (sunrooms)
thermal mass wall/ trombe wall
Passive Solar Heating Systems
These are a;; examples of what solar heating system?
liquid systems
air systems
Active Solar-Heating Systems
What does IECC stand for?
the International Energy Conservation Code
What does IRC stand for?
the International Residential Code
What does ASHRAE stand for?
American Society of Heating, Refrigerating and Air-Conditioning Engineers.
What does NFPA stand for?
the National Fire Protection Association
What are the 4 means of introduction heat into a building?
1) On-site Combustion
2) Electric Resistance
3) Heat transfer from an on-site source
4) Energy Capture
These are all examples of which way to introduce heat into a building?
Oil, Natural Gas, Liquified Gas, Coal, Wood, electricity
On-Site Combustion
These are all types of ____ _____ _____?
Hot water and steam heating
Radiant heating
electric-resistance heating
forced air heating
active solar heating system
Central Heating Systems
This describes what system?
“ heat a building by means of water heated in a boilet and circulated by a pump through pipes toa fin-tube radiator,convector, or unit heater for heating
Hot-Water (Hydronic) Systems
This describes what system?
“use boilets to generate steam that is circulated through piping to radiators
Steam Heating systems
This describes what system?
“can be more energy efficent than hot air systems, by transferring heat directly to objects and occupants without heating large volumes of air first.
1) Radiantly Heated Floors
2)Radiantly Heated ceilings or walls
Radiant Heating
These are all components of?
require no wall space
have no vents
do not interfere with cabinet or furntiure placement
they may raise the heigh of the floor. Necessitating door clearance and possibly cabinet adjustments
Radiantly Heated Floors
These are all compoents of?
Have a lower heat output
do not respond quickly to changing temperature
separate ventialtion, humidity control, and cooling system are required for completely conditioned air
Do not install radiant panels in walls above 48” to avoid hammering nails into electrical coils
Radiantly Heated Ceilings or Walls
_____ _____ Heat
is low-cost
easy to install
offer individual thermostatic control
do not waste heat in unoccupied rooms
do not have to be vented
. However they use high grade electricity for low-grade space heating, so their use should be limited spot-heating a small area for a limited time.
Electric Resistance Heat
This works by heating air in a gas,oil or electric furnace and distributing it by a fan through ductwork to registers or diffusers in inhabitated spaces
Forced-Air Heating
____ ___ are often located in the floor, typically below glass areas
Supply Registers
A seperate system of exhaust ducts draws cool air back through ____ ___ ____ to be reheated and recirculated
Return Air Grilles
