Irradiation onto Solar Surface area

after the right choice of inclination and orientation of the solar panels we get the irradiation onto the solar surface area.

„alpha“ orientation (azimut angle) „Beta“ Inclination (tilt angle) declination from south

The solar yield on the tilted collector surface is higher than the global irradiation on the horizontal collector.

Sun irradiation into a collector array

Variable irradiation over a year Variable irradiation over a day

The goal of each solar collector is to transfer solar energy as much as possible. The losses are divided into optical and thermal losses.

optical losses occurbyreflectionoftheglassand transmission through the glass.

Thermal losses occur by the heat that the collector loses to its environment.

The best solar yields can be achieved, if the required temperatures are low.(forexample55°Corpre-heatingsystems)

overheat and stagnation temperature

at high sun radiation and low energy consumption of a solar panel, the tem-perature of the collector increases up to the stagnation temperature of more than 200°C.Duringthisstagnation,theheatmedium evaporates and expands to the collector piping. This overheat may cause damage on temperature sensible parts and steam hammering results in heavy loads on material. The most part of this damage can be avoided during the design stage if the knowledge about stagnation is considered.

Drain-back System:The easiest way to avoid damage by stagnation temperatures is to drain the system automatically in case of overheat. Butthedisadvantageisthatthesystemcannotberestartedbeforethesolarpaneltemperatureislowerthan100°C.

emergency Cooler:With the integration of an emergency cooler in the solar circuit, the excess energy can be dissipated to the environ-ment.

absorption chiller eaCM

ECOTHERM Solar Cooling

application:Theenergyconsumptionforairconditioningisincreasing.Duetotheintensifieduseofglassfacades,therisingcoolingcapacities do not only touch the Middle east, but also the northern regions with moderate climate.

During summertime we have the highest solar irradiations and the highest demand of cooling energy. This is the perfect match for Solar Cooling. We use the excess solar yields as operating power for our absorption chillers and achieve thereforeaenormoushighsolarsystemefficiency.

Solar Cooling System

The principle of solar cooling

absorption chillers:

our absorption chiller serie eaCM-C.. is operating with heat at very low pressure. The operating liquid is water and a lithium bromide dilution. Water is used as cooling medium and lithium bromide (a stable saltwithhighchemicalaffinitytowatervapour) as absorption medium.

requirements for the cooling tower:

all energy from solar system plus the energy for the chiller circuit have to be dissipaded by a cooling tower. The temperature back to the absorption chiller shouldnotbemorethan31°C.

requirements for the solar system:

The minimum temperature to run the absorption chiller is 75°C. So it‘snecessary to use collectors with low thermal losses. further it‘s an advantage to run the solar circuit by a speed controlled pump.

requirements for the chiller circuit:

The lowest temperature, that we can generate with our absorption chiller is 7°C.Thereturnlinefromthechillercircuitshouldbe12.5°C.Formoreflexibilitywerecommend the use of a chilled water buffer tank.

alternative solutions for the cooling circuitTo avoid the high water demand for a cooling tower, we recommend to utilize alternative cooling capacities for the absorption chiller.

Custom - made design

eCoTHerM as a specialist for Turnkey systems, is allways delighted to supply innovative solutions. on request we design a turn-key solar cooling system tailor made to the local conditions and requirements with focus onhighestenergyefficiency.

ECOTHERMeSC7000 High Performance Trough Solar Collector

advanced absorber coating technology has established the ECOTHERM brand as synonymous with modern quality standards in the solar industry. The use of vacuum coated ultrasonically welded full-face absorbers from copper avoids air turbulences above the absorber’s surface and enables the full surface area of the collector to be utilized. Solar energy is extracted with best possible utilisation of the area available.

Conventional fin Design:air turbulences give rise to heat losses.

eCoTHerM TechnologyClosed surface avoids heat losses.

eSC7000 Collector:TheESC7000ischaracterisedbyhighefficiency,high quality standards and in particular by unmatched ease of installation.Thelow-profile,light-weightESC7000high-performance collectors can be interlinked very easily by means of flatflushoneinchscrewcouplings.Useofflangeplates ensure appropriate venting with mainte nance of the microclimate inside the collector. The patented f low barr ier featured by the eSC7000 produces 100% h igher thermal performance over conventional designs. recessed hexagon nuts and our proven roof accessory set guarantee convenient, safe and fast installationinaccordancewithnormspecificatons. a variety of absorber coating, solar glass cover, interlinkage and insulation options are offered to bestsuitthecustomer’sspecificrequirements. The eCoTHerM eSC7000 high-performance trough collector can be customised to match your requirements.

eCoTHerM - The advanced absorber Technology label

The name ECOTHERM stands for a special, unrivalled technology for the manufacture of large-area absorbers. Ultrasonically welded full-face copper absorbers with lengths ofup tofivemeterscanbeproduced thatmakeoptimaluse of the area available. The collecting tubes are fully covered to suppress air turbulences inside the collector which otherwise would give rise to the loss of heat at the solar glass cover.
