Reliable technological solutions to meet an intrinsic challenge for society

As the largest consumer of energy in Europe, the building industry has made an uncompromising move towards stricter energy efficiency requirements and speeding up the use of renewable energy. For heating, which alone accounts for three quarters of this energy bill, the need is to provide high efficiency technical solutions having a low environmental impact.
The heat pump is a technology that fully meets this need. It extracts heat from the natural environment (air, water, soil) and returns it to the inside of the building (into the radiator water system or into the air), after imparting electrical energy through a compressor. The thermal energy supplied to the building is several times higher than the electrical energy consumption: this is the performance coefficient, which ranges from 3 to 4 for existing machines.

 3 priority lines of research: the "3 C's":

• Increase the Thermal performance Coefficient of machines.
• Contribute to decreasing the Cost to customers of heat pumps.
• Improve the Compactness of components and systems.

The High temperature Heat Pump without auxiliary power able to supply an existing central heating system with water at 75°C in cold weather: An example of successful cooperation with Ecole des Mines de Paris. Know-how, three prototypes and four patents to take an idea through to a high performance prototype and finally on to industrialisation.

The HEAT PUMP programme:

providing market impetus with a programme involving work on ten projects at PhD level or beyond in progress or being organised, and addressing all three priority aspects (COP, Cost, Compactness).
