AdvanClim Solar Heating & Cooling System

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

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

Advantages

Efficient management of heating renewable sources

Heat supply is linked to cool demand

Low power machines are beginning to be available

Low energy consumption

Disadvantages

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.

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

In winter, AdvanSol modules heat the water that gets to the heating pump, reducing this way its energy consumption

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

Benefits

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)

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.
