TEON history❖ TEON is a company that develops, manufactures andmarkets innovative solutions for 'renewable' heating
and cooling of buildings and, more generally, largevolumes.
❖ Several years of applied research at the Science Area
Park of Trieste have led to industrialize a family of
patented solutions in the environmental and energy
domain, awarded with the «Smart Future Mind Award»
in 2011, as they determine no atmosphere emissions,hence paving the way towards a healthier city
❖ “TINA”, our Professional and Residential hightemperature heat pumps (HPs), represents aneconomically viable alternative to traditional heatingsystems, based on fossil fuel boilers, while determining
zero-emission onsite2Why we do it% of Heating and Cooling from RES

About 75% ofRES arebiomasses

65% of GHG are coming from the Heating sector

HP technologies are applied ona small number buildings(mainly the new ones): reason is
the “lagging" innovation in theheating sector compared toother sectors (electricitygeneration, mobility)5Performance of TINA refrigerants vs. F-Gas

(sized on Tavg = 70°C)

Why high temperature matters• Having a great part radiator systems
designed and sized to work with gas fuelboilers (typically older than 30 years), thelow temperature is not practicable, except
by expanding the radiant surface or byradically changing heating
system/terminals (if and when possible)• The renovation of heat distribution andhousing systems is not always
recommendable, both for the onerousness
and the invasiveness, and -sometimes- forthe «historicity» of buildingsRadiator Tavg (°C)

• Moreover, high temperature systems allow
faster and more adaptive response
regulation, following daily temperaturefluctuations
