SUPERIOR TECHNOLOGY SUPERIOR PERFORMANCE 2015 Midwest Regional Sustainability Summit High Efficiency Infrared Heating Presented by: Dave Jones, LEED AP Spears Mechanical Systems, Inc. May 1,

SUPERIOR TECHNOLOGY SUPERIOR PERFORMANCE TOPICS FOR TODAY Infrared Heating vs. Conventional Air Heating How Infrared Works High Efficiency Infrared Heating – Modulating Unitary: Modulus – Fully Condensing Custom Systems – Trigomax High Efficiency Unitary 2

SUPERIOR TECHNOLOGY SUPERIOR PERFORMANCE INFRARED HEATING VS CONVENTIONAL AIR HEATING INFRARED HEATING VS CONVENTIONAL AIR HEATING 3

SUPERIOR TECHNOLOGY SUPERIOR PERFORMANCE UNIT HEATER – TYPICAL AIR HEATING 4

SUPERIOR TECHNOLOGY SUPERIOR PERFORMANCE UNIT HEATER Advantages: – Inexpensive installation – Quick to install Disadvantages: – High Operating Costs Power for Blower Motor – Increases Heat Loss and Stratification Increases Infiltration – Requires Higher Room Temperatures for Comfort Colder Surrounding Temperatures Drafty (uncomfortable) 5

SUPERIOR TECHNOLOGY SUPERIOR PERFORMANCE INFRARED HEATING 6

SUPERIOR TECHNOLOGY SUPERIOR PERFORMANCE INFRARED HEATING - ADVANTAGES Lower operating costs –Low electrical power consumption Reduces heat loss/Reduced fuel consumption –Reduces infiltration –Lower required room temperature Warm surrounding temperatures (from warm surfaces) No drafts 7 INCREASED COMFORT AT LOWER AIR TEMPERATURES HIGHER MEAN RADIANT TEMPERATURE (MRT)

SUPERIOR TECHNOLOGY SUPERIOR PERFORMANCE Conventional heating has greatest heat loss in roof and upper walls Conventional heat is not where it is needed, particularly in high buildings Infrared provides heat where it is needed – People and machines Infrared provides greatly reduced temperature stratification SRP INFRARED SAVES $$ % FUEL SAVINGS ARE TYPICAL FOR INFRARED HEATING COMPARED TO TYPICAL AIR HEATING METHODS! COMFORT IS IMPROVED!

SUPERIOR TECHNOLOGY SUPERIOR PERFORMANCE HOW INFRARED WORKS 9

SUPERIOR TECHNOLOGY SUPERIOR PERFORMANCE SCIENCE OF INFRARED   Sir William Herschel, astronomer, discovered infrared in 1800   Found that the temperature beyond red color of the spectrum was high   The rays were called ‘calorific’ rays and were later known as ‘infra-red’ rays – “beyond red” 10

SUPERIOR TECHNOLOGY SUPERIOR PERFORMANCE HOW DOES INFRARED ENERGY HEAT? HOW DOES INFRARED ENERGY HEAT?...Like the Sun Direct – Line of Site Indirect – Reradiated Infrared – Obeys All Optical (Mechanical) Mechanisms

SUPERIOR TECHNOLOGY SUPERIOR PERFORMANCE MEAN RADIANT TEMPERATURE (MRT) The Net Amount of Radiant Energy Available from Surfaces to Provide Comfort Radiant Comfort Occurs as Energy is Exchanged Between Surfaces

SUPERIOR TECHNOLOGY SUPERIOR PERFORMANCE IMPACT OF HIGHER MRT  Lower Air Temperatures  Less Heat Loss than Designed  Reduced Transmission Losses  Reduced Air Change Losses  Reduced Stratification  Radiant Heat where Needed
