Types of Heating Equipment• Direct Fired (Make-Up Air)

−Largest range of capacitieso80,000 to 4,500,000

million BTUs/Hro2,000 to 25,000 cfmoEnclosed FlameoLow Temperature

Discharge−Medium to large physical

size−Remote T-stats−Modulating for inside and

outside temperatures−95% 100% Efficient

HEATING


Types of Heating Equipment• Hydronic

− Propylene Glycol• Low to Mid Range

−250,000 – 1,200,000 BTU/Hr Input

• No Flame in structure−Heat Exchangers from

50,000 – 200,000 BTU/Hr

−710 cfm – 2,400 cfm• Applicable in tight

enclosures• 70%-80% Efficiency

HEATING


• Indirect Fired– No combustion

contaminates– Contained flame– Requires venting– 70% to 80% fuel

efficient– Fuel Oil Fired

HEATING


Frost Removal

• Frost Removal−Hydronic−Mobile Ground Heater

oDiesel, natural gas, propane

oCoverage from 1,500- 12,000 sq. ft)

oVarious Applications

HEATING


Cooling Equipment

• 1-5 Ton Portable • 3-75 Ton Industrial• Chillers• Dehumidifiers• Air Handlers

COOLING


Dehumidifying Equipment

• Portable: 6-28 gallons of H2O/day

• Industrial: 28-387 gallons of H2O/day

• Desiccant• Refrigerant

DEHUMIDIFYING


What is Air Quality?• “Healthy Air”

– Ambient or indoor air which is free from harmful contaminants and contains 19.5 to 22% oxygen (suitable for breathing)

• “Clean air”– Air of such purity that it

will not cause harm or discomfort to an individual if it is inhaled for extend periods of time

• OSHA Regulations (stds-29 CFR) Ventilation – 1926.57


Ventilation Issues• Chemicals/Fumes

– Paints, Glues, Varnishes

– VOCs-carpeting, cabinets, furniture

• Dust/Particulates– Diesel exhaust

– Grinding/Sandingo Silica, Lead

– Weldingo Galvanized steel-CR, NIo Stainless Steel-ZN, flux

HEATING


Safety IssuesUse of Outside Air Can Help Reduce Safety Concerns

• Ventilation of Harmful Fumes– Paints, Glues, Varnishes, etc.– 3 main byproducts of combustion

oCO, CO2, H2O

• Carbon Monoxide (CO) Reduction– OSHA levels– Many sources on a job site

HEATING


Direct Fired Make-up Air• Pressurizes the structure

– Minimizes infiltration & cold spots

• Uniform heat distribution• Controlled ventilation (0.5-

1.0 AC/Hr)• Absorbs moisture,ventilates

toxic fumes and excessive moisture

• Lowers relative humidity levels and dew point

surface temperatures

HEATING


Moisture Problems• Condensation on

interior walls• Condensation freezes• Importance of

Mechanical Ventilation


Desiccant DehumidifiersTD-5000 Desiccant

TD-2000 Desiccant TD-600

Desiccant

DEHUMIDIFYING


Heating Applications

• New construction or retrofits

• Masonry work• Drying or fireproofing• Taping, painting, and

other interior finish work

• Concrete pours• Supplemental or

emergency service• Military & disaster relief• Special events

HEATING


Dehumidifying Applications

• Concrete curing• Surface

preparation & treatment: drywall, painting, and other coatings

• Water damage restoration

DEHUMIDIFYING


Cooling Applications• New construction or

retrofit finishing• Process application

cooling• Supplemental or

emergency service• Dehumidification• Military & disaster

relief• Special events

COOLING

• Analysis of ventilation requirements to ensure compliance with OSHA regulations
