Refrigerant-Free Heat Pump
The Sencera Stirling Zero-
Carbon Heat Pump is 30% More
Efficient than traditional units.
The Sencera system shuttles a working gas (typically nitrogen or helium) between a heat absorbing exchanger and a heat rejecting exchanger. The pressure and volume of the working space are varied sinusoidally, with a phase offset in time between them to form a Stirling thermodynamic cycle. As a result, the gas changes temperature so that it is colder than the absorber during part of the cycle and warmer than the rejector during a second part of the cycle.
THE SENCERA STIRLING HEAT PUMP
Sencera draws upon more than a decade of expertise in designing Stirling cycle systems. Its newest system is a 10 kW (3-Ton) capacity unit that is cost-competitive with traditional HVAC units. It can be scaled for other load capacities.
THE INCUMBENT (RANKINE) REFRIGERATION CYCLE
A Rankine cycle system utilizes phase change material (typically a CFC or hCFC) to move heat between two environments. These units have a huge impact on the environment both in electricity consumption and refrigerant leaks. Current chemicals (such as R410a) are harmful to both health and the environment.
REFRIGERANTS LEAK AND
ARE TOXIC TO HUMANS
AND THE ENVIRONMENT.
The most common service required for an air conditioning or heat pump is refrigerant replacement. Over time all systems leak. Refrigerant molecules are typically long carbon chains where hydrogen bonds have been filled with Chlorine and Fluorine (CFC’s and hFC’s). These chemicals are tailored to boil and condense at pressures and temperatures to facilitate heat movement.
The Montreal Protocol (with subsequent revisions) was created to address CFC and hCFC pollution. This international accord is an agreement to phase out their use.
WHY A STIRLING HEAT PUMP?
A Zero Carbon Heat pump is better for the environment and saves money.
