This page introduces the latest information on Da Vinci's technology and RHE
Started Oder Acceptance of Small-Sized Rotary Heat Engine (RHE)
for Academic Research
The system is designed for research institution. It is possible to change the design according to your research purpose.
Time of delivery will be around 4-6 months after receiving order. Manufacture cost depends on the system configuration, so we will provide the estimated price and terms of payment after having meetings on specification.
The figure is a concept image of RHE 1kW system.
(※The specification or shape may be changed without notification.)
System size: W 1,260 D 615 H 1,080 ㎜
Estimated sales price: 4 million yen (Shipping cost is NOT included)
(2 million yen is paid when its order, lest of the amount is paid when delivered)
CAD data is available from here.
Started download of RHE Invest Quick Simulator!
This file enables invest simulation and recovery simulation of geothermal power generation.
The simulator is Excel file style.
Input the data to blue cells in the Excel file, and you will get calculation result.
You can download the file from here.
Our RHE systems are applicable to variety of fields.
We would like to introduce the examples of our business and research theme.
Geothermal power generation drains hot water. We use the drained water for for heating in plant factory.
In the first process, dry waste of domestic animals. In the secondary dry process, use natural energy (such as Fresnel sun house) for drying. After that, the hot water which is draind from biomass boiler will be used for RHE and electricity will be generated. Moreover, waste heat can be used for secondary dry process.
We are developing Fresnel sun house with RIKEN.
Polygon sun house collects sunlight, converts to thermal energy, and stors the energy.
The reason why we convert light energy to thermal energy is that storing heat is easy.
By storing heat, we can generate electricity for the amount of heat storage capacity when it's necessary.
