The Carbon Dioxide Heat Pump Water Heater Technology and the Comparative Analysis of Performance

As a kind of natural fluid, carbon dioxide is an attractive alternative to the synthetic fluids in heat pump systems, for it is environmental benign and owns good thermal properties. The principle of carbon dioxide heat pump was described. The application of carbon dioxide heat pump water heaters and the current status of carbon dioxide heat pump technology at home and abroad were described, too. Then a comparative analysis was made for different brands of carbon dioxide heat pump water heaters. Finally, a comparative analysis of economic performance between carbon dioxide heat pump water heaters and water heaters with other heat sources was carried out by calculating the annual consumption costs. The results show that carbon dioxide heat pump water heaters have more advantages than other water heaters in both economic aspect and performance systems, so they have very large space for development.
