EFFICIENT AND SAFE USE OF REGENERATIVE ENERGIES
Safety and efficiency are the key criteria when installing and operating solar thermal energy systems.
EFFICIENT OPERATION OF THE SOLAR THERMAL SYSTEM
When used in conjunction with conventional heating systems, regenerative energy systems secure the thermal energy requirements of buildings. Special requirements apply when integrating solar thermal systems. In addition to intrinsically safe operation, the efficient transfer of solar heat from the collector to the thermal storage station is an important criterion. The efficient operation of the solar thermal system largely depends on the system being correctly ventilated and the performance-specific adjustment of volume flow.
INTRINSIC SAFETY OF SOLAR THERMAL SYSTEMS
Solar stations link the collector circuit to the solar storage tank. The most important functions are pumping, regulating and ventilating in order to ensure safe and efficient operation of the system under all operating conditions.
Thus, the function of a solar station is not just to circulate the solar fluid, but also:
- Demand-driven volume flow regulation
- to protect against circulatory malfunctions
- to protect the components from overpressure
- to monitor the temperature
- to separate the air
In addition, the solar station makes it easier to perform maintenance tasks when filling and emptying the various circuits by means of the integral multifunctional valves.
PROTECTION AGAINST STEAM AND CAVITATION
One of the design features of the TacoSol Circ solar station is the connection for the solar expansion vessel on the intake side in front of the pump. This prevents a negative operating pressure (underpressure) from building up in front of the pump, thus ensuring that the expansion vessel and circulating pump are protected from cavitation.
AUTOMATIC AIR SEPARATION
It is necessary to ventilate the solar circuit after it is first filled and during ongoing operation. Air pockets impair the operation of the system, reduce solar yield and also cause the solar fluid to age prematurely.
The TacoSol Circ solar station has an integrated ventilating flask with built-in manometer, the innovative design of which ensures automatic air separation both when filling the system and during ongoing operation. This makes it possible to ventilate and check the pressure of the solar circuit directly at the station. This saves time when commissioning and maintaining the solar station.
VALVE AND PUMP GROUP FOR THE INTRINSICALLY SAFE OPERATION OF SOLAR STATIONS
As a compact, preassembled valve group, the TacoSol Circ solar station brings together the most important regulating and safety components, such as circulating pump, safety valve, non-return valve, flow rate control, ventilating flask, manometer and thermometer.
THE SUN EVEN POWERS THE PUMP
When connected to a photovoltaic panel, the TacoSol Circ PV EU21 also uses the solar energy to power the circulating pump. The intensity of the incident sunlight regulates the rotational speed directly by means of the solar-generated pump current, thereby also controlling the performance of the pump. This makes it possible to operate the solar thermal energy system completely independently, so that there is no need for a mains power connection.
In addition, the optional DC-Control pump controller can be used to increase the efficiency of the system.
SAFE USE OF SOLAR ENERGY
The pre-assembled, pre-configured components in the solar stations make it easier to plan, install and efficiently operate the solar thermal energy system.
