2 Traditional heating & cooling systems present considerable disadvantages, especially a high level of energy consumption (1) Source: La Vola Companyia de Serveis Ambientals, SAL Main disadvantages High energy consumption In office buildings, heating represents between 40% and 65% of electricity consumption (1) Noise Pollution Internal: produced by fans External: produced by cooling towers and air to water machines Increase of legionella scattering risk In water to water systems Poor air quality High incidence of colds produced by air circulation Frequent complaints from users due to overexposure to either cold or heat Basic elements of a traditional heating & cooling system Basic elements of a traditional heating & cooling system Chiller Either water to water or air to water: in buildings Air to air: in households. Cooling towers In water to water systems. Mixing ventilation Refrigerated air recirculation to reduce energy consumption
3 There are other heating & cooling systems based on renewable energy, but they also show important limitations AdvantagesAdvantages Efficient management of heating renewable sources Heat supply is linked to cool demand Low power machines are beginning to be available Low energy consumption DisadvantagesDisadvantages High cost of the system because of the machine and the considerable size of the collectors field required High maintenance expenses Poor architectonical integration: it requires a big surface of solar panels Increase the risk of legionella scattering Poor air quality, colds, complaints from users Requires the use of chemical products to refrigerate Solar panels with absorption machine Efficient management of land energy (~50% savings) Simple and proven technology Geothermal energy High digging and perforation expenses: large investment return Depends on geothecnical peculiarities If radiant floor is used to refrigerate: Needs dehumidifiers Lacks the power required to refrigerate buildings with moderate or high thermal load
4 AdvanClim heating & cooling system, developed by Hemera Group, solves all these problems. Heat in winter, cooling in summer, and sanitary hot water all year round Maximum comfort feeling for people Noise free running Reduce legionella and bacterial colonies risk Keeps heating & cooling inner conditions for a long time (thermal inertia) whenever a failure of the system or an electricity supply disruption occur. AdvanClim heating & cooling system specifications Features Consumption and energy costs Use of renewable energy Has a very low energy consumption and therefore low energy costs Low installation cost or, if higher than the one of a traditional system, guarantees investment return in less than 4 years thanks to the energy savings obtained Low maintenance cost Architectonical integration Practically invisible from outside Takes little space of the roof Reduce pipes volume to the minimum Running and maintenance Strong and long-lasting: Immune to impacts, no freezing nor overheating risks

8 T agua = 15ºC Impulsión 35ºC T suelo = 22ºC T agua = 20ºC Retorno 30ºC Acumulador de inercia In summer, AdvanSol hydro-solar modules cool the water that gets to a water to water heating pump, thus reducing its energy consumption Note: The temperatures indicated are estimated ones and may suffer variations depending on the specific building Performance simplified sketch
9 In winter, AdvanSol modules heat the water that gets to the heating pump, reducing this way its energy consumption Note: The temperatures indicated are estimated ones and may suffer variations depending on the specific building. T agua = 29ºC T suelo = 23ºC T agua = 24ºC Impulsión 7ºC Acumulador de inercia Retorno 12ºC Performance simplified sketch
10 AvdanSol hydro-solar modules not only save energy but also gives a number of benefits Benefits Energy savings in heating, cooling and hot water Easy architectonical integration Height < 1 m Requires little surface (from 3% to 5% of the surface considered) * Require no reinforcement of the surface it is settled on Weight < 25 kg/m2 Lack of noise and vibrations It doesn’t include mobile mechanical parts of any kind Highly reliable Use of an auxiliary air to water machine to cover long periods without sun Strong system with little maintenance requirements No freezing nor overheating risk, no mobile mechanical parts Minimize legionella scattering risk Aerosol scattering considerably lower if compared to refrigerating towers Low risk ranked, within the same category of park fountains and irrigation systems Refrigerating tower AdvanSol roof Aerosol emission measures obtained through hydro sensitive paper * Depending on the particular building, it may be necessary to consider an additional collecting surface for winter. Such surface will depend on the target energy qualification.
11 Radiant floor provides high energy efficiency and great comfort feeling BenefitsBenefits High energy efficiency It works at temperatures very close to environment ones It works only on the area occupied by people (stratification) Reduces the thermal load produced by the radiation getting in through windows and doors or glass walls. Reduces the transmission thermal load getting in through windows, doors, floor and roof. Highly energy selective (supplies heat or cold only where required) Lessen thermal load oscillations and, therefore, compression consumption. Great comfort feeling Thermal sensation in summer similar to the one at a cathedral Homogeneous and silent distribution of energy Thermal inertia Keeps heating & cooling inner conditions whenever a failure of the system or an electricity supply disruption occur.
12 Finally, AdvanVent displacement ventilation reduces even more energy consumption and provides higher comfort and air quality levels Energy consumption savings Expels convective thermal loads It works at temperatures close to comfort ones Drives little air flow It works only on the occupied area Only where it is necessary Allows a higher use of free-cooling Reduces consumption on last floor Makes it unnecessary the use of fans and recirculation filtres Provides higher comfort level Ensures a cleaner and healthier air Reduces colds incidence Benefits Heating & Cooling traditional system (mixing ventilation) Heating & Cooling traditional system (mixing ventilation) AdvanClim system (AdvanVent displacement ventilation) AdvanClim system (AdvanVent displacement ventilation) Air is introduced at low temperature and high speed, being mixed with the air of the rooms Refrigerated air is recirculated to reduce energy consumption The air introduced is only the necessary one to ventilate the building It is introduced air at a moderate temperature and at low speed Hot air is expelled, instead of mixing it with refrigerated air Air is not recirculated and no turbulence takes place
13 As a result, AdvanClim system supplies high energy savings that may reach up to 73% Note: The figures have been taken from a traditional system based on air to water machines. AdvanClim system energy savings compared to traditional heating & cooling systems -30% -20% -30% -73% Energy savings up to 73%
14 All buildings where AdvanClim system has been installed have achieved important energy savings Household at Osuna town Surface of application (m 2 ) Surface of application (m 2 ) Estimated consumption (MWh/year) Amortization (1) (years) Amortization (1) (years) Traditional Heating & Cooling system 4503,5 San Telmo Educational building (Province of Málaga) 8502,0 Torcal Guest Centre (Antequera city) Torcal Guest Centre (Antequera city) 4302,0 Image of the installation (1) Amortization calculations have been carried out based on old electricity fares, without considering neither subventions nor the savings derived from the absence of thermal or photovoltaic solar installations requirements. -66% -72% -74%
