The Performance Analysis of Sea Water Heat Pump applied Low GWP Refrigerants
: In this study, the seawater Heat Pump System using seawater with temperature of annual domestic conditions (0 ℃ to 25 ℃ ) is designed in order to compare its performance against the Heat Pump using unused heat of seawater. As a potential replacement for current refrigerants that exacerbate global warming and ozone delpetion, a Low GWP refrigerant’s performance is analyzed. The basic water to water Heat Pump system is chosen and three commercial refrigerants - R134a, R410a, R32 – are used to compare against new Low GWP refrigerant R1234ze. When seawater with temperature of 25 ℃ is used, the performance change showed maximal increase in COP, 38.3%. low GWP refrigerant R1234ze, showed great performance characteristics reach to 5.242 and Existing commercial refrigerant, R134a showed only less than 0.03 performance difference against R1234ze. The study confirms notable performance of R1234ze refrigerant through simulation as environmentally friendly refrigerant for domestic seawater Heat Pump.
