Avviata con successo la prima RHTHP presso Sotacarbo

Avviato il primo impianto con tecnologia RHTHP presso il centro di ricerca Sotacarbo a Carbonia

June 2026
È stato avviato con successo presso il centro di ricerca sulle energie rinnovabili di Sotacarbo, a Carbonia (Cagliari), il primo impianto dotato della tecnologia RHTHP (Reversible High Temperature Heat Pump). Si tratta di una macchina innovativa e unica nel suo genere, in grado di operare sia come ciclo ORC (Organic Rankine Cycle) per la produzione di energia elettrica, sia come pompa di calore ad alta temperatura per l'accumulo di energia termica. In modalità ORC, la macchina scarica un accumulo termico a circa 110°C, convertendo l'energia termica immagazzinata in energia elettrica. In modalità inversa, la stessa unità funziona come una pompa di calore ad alta temperatura, trasferendo energia da una sorgente termica a bassa temperatura verso un accumulo termico, caricandolo con energia sotto forma di calore ad alta temperatura. Grazie a questa doppia funzionalità, la tecnologia RHTHP consente di realizzare una vera e propria Batteria di Carnot, permettendo di accumulare energia utilizzando semplici serbatoi di acqua calda invece di costose batterie elettrochimiche. Questa soluzione offre importanti vantaggi in termini di sostenibilità, sicurezza, durata e riduzione dell'impatto ambientale. L'avvio dell'impianto presso Sotacarbo rappresenta un importante traguardo nello sviluppo di sistemi innovativi per l'accumulo energetico e per l'integrazione delle fonti rinnovabili nelle reti energetiche del futuro.

Low Temperature District Heating in Pinerolo

Feasibility study for a district heating network in Pinerolo (To)

May 2021
The advent of the 4th and 5th generation of district heating networks and the flexibility of the ORChidea platform allow significantly improve the efficiency of the networks thanks to new plant solutions. The low discharge temperature of the networks allows to send the heat directly from the condenser of the ORChidea systems, which can be fed at the evaporator with biomass or solar thermal, making the networks work with renewable energy only.

Kaymacor single-phase platform

The platform for single-phase applications has been released. From today Kaymacor systems can also be connected to single-phase networks. As required by law, the maximum power that can be connected to a single-phase network is 6 kW

nov. 2020
In November, the model platform that can be connected to the single-phase 230 V (50 or 60 Hz) power grid is being released. From December the kaymacor ORC modules will be able to be connected to single-phase 230V networks. This possibility is limited to ORChidea 3LT, ORChidea 6LT e ORChidea 5MT models since the legislation provides for connection to the single-phase network only up to an electrical power of 6 kW. The platform is open to the development of single-phase applications at voltages other than 230V.

kaymacor collaboration with Olokliromeno Kentro Greece

Nov.2020
Kaymacor collaborates with the Greek company OLOKLIROMENO KENTRO ANAKIKLOSIS SA and the Institute of Chemical Engineering Sciences based in Patras as part of a research on a new technology on the recovery of hazardous waste, to remove total organic carbon (TOC) by converting it in gas. In this project Kaymacor supplies ORChidea 5MT unit capable of transforming the useful heat present in the gas flow into energy. For this application, kaymacor has also designed the economizer that recovers heat from the fumes of the innovative process. The solution identified is a double spiral coil solution. Kaymacor calculated and designed the compo. Then he sent the construction drawings to the final customer to build the economizer directly on the plant.

ORChidea 3LT at NRIAG Egypt

Kaymacor ORC at National Research Institute of Astronomy -Cairo - Egypt and Geophysics (NRIAG)

Oct. 2020
Kaymacor and solar cooling applications The Kaymacor low temperature models (KC-LT) can be used for solar cooling applications. Fed with water in the temperature range of 60 - 110 °, they provide the electrical power needed to power traditional steam compression cooling cycles. The company has built three plants by integrating its technology with concentrating solar collectors. In this context, a low temperature model will be delivered in December to the National Research Institute of Astronomy and Geophysics NRIAG in Cairo in Egypt. The possibility of powering the ORC from both a solar source and a biomass boiler makes the ORC a unique technology able to use two renewable energy sources in parallel (sun and biomass) and to be able to store energy not only in batteries but also in thermal form. ORC machines can also be used in conjunction with absorption machines. In this case, the overall efficiency of the solar cooling system increases further.

Kaymacor and Energies Communities

The development of renewable communities as required by European Directives, recently implemented by European Countries such as Italy, can benefit from Kaymacor technology

Sept. 2020
The possibility of using the ORChidea platform in combination with solar thermal and biomass with thermal and biomass storage makes it particularly suitable for energy communities or for multi-energy systems (Multi-Energy Systems, also called DES District-Energy Systems). These systems integrate energies renewables, various energy networks (gas, electricity, district heating and remote cooling), cogeneration and energy storage. These systems represent one of the most promising solutions for reducing CO2 emissions.

Contribution: "A Novel Micro-cogeneration Unit for Market Applications Based on a Biomass-fired ORC System

September 2019
Contribution Abstract: Organic Rankine Cycle is one of the most efficient, profitable and feasible technology for low-to-medium temperature heat recovery. The boost to the development of small-scale systems that could easily enter the market poses challenges in layout design and selection of components. This work deals with a micro-scale ORC unit conceived to be cheap, efficient and compact. The transient response of the system has been experimentally investigated and simulated with large variations of the heat source. To this end, a dynamic model is built and validated against a large set of experimental data. The final goal is to show the real potential of the system in terms of market applications, for which best design choices, operational limits and response time to variable heat sources must be identified. Results proved the fast time response of the system that promptly reacts to variations of the heat source temperature. The model is able to capture well the system dynamics, showing maximum relative errors of about 5% in the prediction of both output power and high pressure. The choice of scroll expander, volumetric pump and plate heat exchangers is made according to the lowest cost-to-efficiency ratio to keep the investment cost below 2500 euro/kW already at the pre-market phase. The additional heat production (around 15 liters/min at 40°C) amplifies the market potential in isolated domestic applications and paves the way for further cost reductions.
