FORCED AIR-- components
|
furnace, fuel storage, chimney, ductwork, outdoor condensing unit (for cooling)
|
|
|
FORCED AIR-- advantages
|
Incorperates humidification, dehumindification, air filtration and cooling equipment; provides quiet, fuel efficient, even heat distribution
|
|
|
FORCED AIR-- disadvantages
|
Multiple zoning is difficult to create and requires high energy usage
|
|
|
FORCED AIR-- variations
|
Heat Pump Furnace, Multifuel Furnace, Packaged System,
|
|
|
FORCED AIR-- Heat Pump Furnace
|
Uses reversable refigeration cycle to create and circulate either heated or cooled air as required.
Economical to operate in moderate climates Can be used if water or earth (not air) are used as heat source. Inefficient with temperatures well below freezing |
|
|
FORCED AIR: Multi-Fuel Furnace
|
Designed to burn wood or coal as well as a back up fuel source (gas or oil)
|
|
|
FORCED AIR: Packaged System
|
Single/ Split Packaged units
Installed on the roof or a concrete pad. Supply and return ducts are connected from the fan inside the unit back to the building. Typical commercial application Uses electricity and/or gas |
|
|
HYDRONIC HEATING: components
|
boiler, fuel storage, chimney, expansion tank, circulator pumps, zone valves, convector or fan-coil units
|
|
|
HYDRONIC HEATING: advantages
|
Quiet operation, excellent heat distribution, easily zoned for individual control, compact equipment
|
|
|
HYDRONIC HEATING: disadvantages
|
Not capable of cooling, convectors occupy valuable wall perimeter.
|
|
|
HYDRONIC HEATING: variations
|
Multi-fuel boiler, Radiant Heating,
|
|
|
HYDRONIC HEATING: Multi-Fuel Burner
|
Burns coal or wood with backup fuel (gas or oil)
Larger and more expensive than a single fuel burner |
|
|
HYDRONIC HEATING: Radiant Heating
|
Heating coils located in ceilings or floors may be warmed with hot water from a boiler
|
|
|
ACTIVE SOLAR: components
|
solar collector panels, heat storage tank or bin, ductwork for air collectors/ piping for water collectors, heat exchanger, building heating ductwork
|
|
|
ACTIVE SOLAR: advantages
|
Zero fuel cost, No pollution
|
|
|
ACTIVE SOLAR: disadvantages
|
High initial cost, collector surfaces dominate aesthetic, full back up system required for sunless period, not capable of cooling
|
|
|
EVAPORATIVE COOLER: components
|
Evaporative cooling unit, ductwork (hot/dry climates only)
|
|
|
EVAPORATIVE COOLER: advantages
|
low costs
|
|
|
EVAPORATIVE COOLER: disadvantages
|
difficult to control humidity,
inefficient in humid climates, separate system required for heating |
