WaterGlycol mixtureCharacteristic


The operation with water:

- allows easy, direct connection to the in-house heating network,

- requires less equipment such as heat exchangers, de-aerators, valves, pumps and others

- is the precondition for the use of efficient and small storage tanks,

- eliminates the high costs for antifreeze and the associated running costs,

- considerably reduces the costs and time for commissioning and repairs,

- ensures a long operating life with almost constant performance,

- removes all risks associated with thermal stagnation and- minimizes running costs (e. g. maintenance).


Until now:as a collector heater!New:the collector as 2nd boiler!

A brilliant idea

* Internal self correction possible

• No throughput (pump defective)• Throughput too low (kink in pipe)• Air in system (commissioning, leak)• CPC supply and return interchanged • wrong placed or defect sensors• Gravity brake leaking (soiled) *• Wrong time setting *• Pressure loss (leak, blow off over SV)• Wrong hydraulic structure • No permanent power supply (light switch)

Solar process heat potential in Germany

Total process heat requirement approx. 45,000,000,000 kWh per annum in Germany

Solar fraction 25 %:- 35,000,000 m² CPC collectors,- more than 5000 football fields,- 100 times current Paradigma

CPC surface area > 5,000


Main barriers to large-scale systems

High temperatures for process heat cannot be achieved with flat plate collectors.

Solar input with “summer collectors” is far too low and economically inefficient.

Most large-scale systems constructed till now outside of Paradigma competence work badly or not at all.

Operators shy away from ageing and replacing of the heat transfer medium.

Difficulties and complexity grow with the size of the system.

Ideal solution - large-scale solar energy systems according to the Aqua principle

LSS Large-scale Solar-thermal Systems

The advantages of the AquaSystem in LSS- The solar system works like an additional boiler with freely selectable temperature.

- Solar heat exchanger, antifreeze and additional fittings are not necessary. This reduces the costs enormously.

- No more overheating problems! Process heat collection up to 130 °Cis possible with this. The system can be placed in a standstill condition withoutreservations. This allows the use of a smaller, more efficient tank.

- An outstanding thermal stratification in the tank and a minimum tankstorage requirement ensure extremely fast availability of the solar heat.

- Compared to conventional operation, approx. 50 % of pump running time and pump energy is saved over the year.

- The comprehensive functional monitoring of the controller discovers and signals faults immediately, this ensures optimal operation.


Large-scale Solar-thermal Systems (LSS)

Characteristic:

• collector array sizes > 30 m²

• Special appliances like cooling systems, process heat, etc.

• Special hydraulic systems


Solar preheating of fresh water for DHW

Large-scale Solar-thermal systems (LSS)


Solar instant heating of fresh water and room heating support with parallel backup heating for new buildings and small district heating



Direct solar field connection to already existing heating systems and networks

This type of installation is high-efficient, nearly universally applicable and has the shortest payback period.

What are the risks?

• Falling energy costs – very unlikely

• No more state subsidies – interest approx. 2 % less

• Failure of the LSS – reduced to a minimum by functional monitoring / yield guarantee from Paradigma

• The sun shines no longer – then we humans will have other things to worry about


What a human being really needs is ...
