Determination of the specific heat capacity (cp) of heat transfer fluids
Our procedure to determine the specific heat capacity of heat transfer fluids is providing an accuracy of ± 0.3 – 0.5 %. This is significantly more accurate than standard values that are declared with an uncertainty of ± 3 – 5 % in data sheets of products on the market. A higher accuracy of these important values increases confidence in your products. This is indispensable for the monitoring of energy balances of heating and cooling applications.

Mobile photovoltaic test laboratory
With our mobile PV test laboratory we run detailed tests and measurements of PV modules on-site. The tests include I/V curves, electroluminescence, infrared imaging and HighPot measurements. The mobile test lab measures in a matter of seconds and delivers resilient information e.g. in case of suspected loss of efficiency or safety-related deficiencies of panels, as well as for general quality checks during operation or as inspection of new panels delivered to a storehouse or on-site.

Information about the testing methods ...

Walk-in climatic chamber
Our walk-in climatic chamber measures 2.0 m x 2.7 m x 4.5 m (H x W x L) on the inside and can be run at temperatures from – 40 to +85 °C. Moisture can be controlled in the range of 15 to 95% above 7 °C. We can run constant conditions as well as any kind of time dependent profile for temperature and moisture.

Solar Tracker
Several solar trackers are installed outdoors and allow for the testing of components under normal irradiance, including accelerated ageing and depenency of parameters on the angle of incidence of solar irradiance. Fluid circulation loops are available for cooling or heating of the exposed specimen.

Solar Simulator / Artificial Sun
Our indoor solar simulator enables testing of larger objects with predefined and repeatable conditions for solar irradiance and environmental conditions. Examples of application are the testing and optimization of solar collectors and othere elements of the building skin, resistance of materials to extreme conditions of irradiance, infrared imaging of objects under solar irradiance, and many more.

Test rigs for components of heating systems
For the development of pumps, thermal compensators, sealings, solar fluids, DHW modules etc., different test benches are available that can be adapted to almost any kind of problem definition.

Spectroscopy
A wide range of spectrometer systems are available for the measurement of spectral radiation distribution (radiometrics) and for the determination of absorption, emission, reflection and transmission of materials.

Termografia
La termografia permette uno sguardo nel mondo della radiazione termica. La nostra macchina termografica raffreddata a nitrogeno liquido rende visibili i punti deboli.

PIV e LIF
Con Particle Image Velocimetry l’SPF può analizzare processi fluidodinamici, ad esempio intorno a parti interne di bollitori. Tramite la Laser Induced Fluorescence (LIF) si può rilevare inoltre la distribuzione della temperatura nel fluido in movimento.

Concise Cycle Test for combi-systems
The Concise Cycle Test (CCT) method is used for the determination of the functionality and efficiency of combined heating systems for domestic hot water and space heating under realistic conditions based on a six day dynamic hardware in the loop test profile.

Simulazione ambientale
Nei nostri armadi climatizzati e nei forni ad alta temperatura possono essere testati materiali e componenti per la loro resistenza contro le influenze ambientali come la temperatura, l’umidità, la condensazione e la radiazione.

System Simulations
The SPF institute for Solar Technology has a long and vast experience in the simulation of complex energy systems with Polysun and TRNSYS. We are not only users of these programs, but also develop our own codes for components, control and systems. Thus, our possibilities go far beyond the tasks a normal user can accomplish.

Building Simulation
For building simulations IDA-ICE and TRNSYS are used at SPF.

EES
EES è un programma per la risoluzione di equazioni. Grazie all’interfaccia grafica programmabile possiamo programmare applicazioni specifiche per i nostri clienti. (TubeCalc è stato programmato dall’SPF in EES.)

Raytracing
Attraverso l’impiego di un programma Raytracing non sequenziale può essere ottimizzato il rendimento ottico di collettori con superfici riflettenti.

FEM
Il Finite Element Method può essere utilizzato in tutti quei casi in cui dei processi complessi di conduzione termica non possono più essere risolti analiticamente.

CFD
Tramite Computational Fluid Dynamics possono essere modellati, diversamente dal FEM, oltre ai processi di conduzione termica anche dei processi di trasporto materiale. In tal modo si deducono anche processi fluidodinamici in liquidi e gas delle simulazioni.

Accelerated Lifetime Testing (ALT)
I test di invecchiamento accelerato (Accelerated Lifetime Testing) permettono previsioni sulla durata di vita di nuovi materiali, come ad esempio dei rivestimenti di assorbitori solari, a determinate condizioni di impiego.
