Development of a residential brine-to-water CO2 heat pump system.

Author(s) : STENE J.

Summary

Compared with heating systems based on electricity, oil, and natural gas, electrically driven heat pumps for heating of homes reduce the primary energy demand by typically 50 to 80%. As a consequence, the heat pump technology offers substantial CO2 reductions over conventional oil boilers. In comparison with high-efficiency gas fired boilers the reductions in CO2 emissions are less pronounced, and when electricity is generated in coal fired CHP plants a COP above 2.5 is required in order to attain a net CO2 reduction. Since there is a much higher potential for efficiency improvements in heat pumps than in oil and gas fired boilers, the main effort with regards to future residential heating systems should be concentrated on developing high-efficiency heat-pump systems.
