1 Development of multi-function CO2 Heat Pump Water Heater
2 Background of multi-function water heater Market trend of gas combustion multi-function water heater X Market of multi-function hot water heater is is glowing Energy consumption at residence Annual report of residential energy statistics (1999) Proceed energy saving based on Top Runner Approach standards of energy efficiency Lighting, electric appliances e.t.c. Cooling 2.4% 36.3% Hot water feed 33.8 Space heating 27.5% year Need to develop high efficiency system
3 Main task of multi-function heat pump water heater Characteristics of multi-function system Use hot water in the storage tank directly for hot tap water Use hot water in the storage tank indirectly for heat source of space heating Heat pump unit Water-Ref. HE. Ejector Evap. Compressor Higher temp. water than feed water Tank unit Tap water Tank High temp. 55 Feed-water Primar y heating circuit 45 Secondary heating circuit Water - Brine HE 40 Bath Shower Space heating Main problem Return water from primary heating circuit is mixed into cold feedwater Heat pump COP becomes down with higher inlet water temp.
4 Countermeasures of task pressure Characteristics of CO2 heat pump Decline of heating capacity and cop under high inlet water temp. cond. Isotherm. high Heating capacity Heating capacity Higher inlet water temp Electric power Countermeasures for decline of COP To use return water for tap water ( medium temp. water) Development of Cascade heat process system To improve heat pump cop at higher inlet water temp. condition Development of ejector cycle for heat pump water heater enthalpy
