BOCALT, heat for a more sustainable energy

We design and develop a novel heat pump for applications with high temperature heat sources

One of the lines of action for reducing CO2 emissions is the decrease in the consumption of fossil fuels and the increase in the production of energy from renewable sources.
In this context, the recovery of residual heats, which are currently not being used, and the use of various types of renewable energies, which can be captured at medium temperature, such as solar thermal energy or medium enthalpy geothermal energy, would be important advantages both environmental and energy consumption reductions. In the same way, it would allow the increase of the use of renewable energies.




Is an R&D project that consists of the design and development of a new heat pump capable of using heat from sources at high temperatures (between 30ºC and 60ºC). This solution allows us to recover waste heat from industrial processes or renewable energy sources, capable of heating fluids to temperatures close to 80 ºC with high efficiency, incorporating a natural refrigerant that not only meets the requirements of the new F-Gas regulation for this type of equipment but scores highest on global atmospheric warming potential indices. All this, without damaging the ozone layer, and also using the latest generation inverter (modulating) compressors.
The potential for using this technology is enormous since it can be implemented in energy rehabilitation projects to replace boilers while maintaining radiators, in centralized sanitary hot water heating facilities without the need for a sanitization system, for heating process or industrial fluids. , to take advantage of the heat recovered from fluids or residual effluents, or to use springs or geothermal wells with low enthalpy (30 to 60 ºC), etc.
