abstract

One CO2 heat pump water heater test apparatus was built in the paper. The heat transfer characteristics of CO2 in gas cooler with water in double-pipe heat exchanger was experimentally investigated. The effects of variation of cooling water flux on heat transfer characteristics, outlet temperature of water, COP and CO2 temperature were analyzed. The influences of cooling water flux to heat exchange about CO2 side, water side, and the CO2 and water temperature matching was analyzed. Experimental results showed that the supercritical CO2 heat pump water heater can acquire higher temperature of outlet water up to 80°C than those conventional Freon heat pump water heater, and the COP of the system increased with the increase of water flow rate through gas cooler. All the work was valuable for the application of CO2 heat pump water heater.
