Figure 3 Energy saving by using heat pump Figure 3 shows energy saving in percentage when operating with heat pump in comparison with conventional heating system (electrical heating coils), the graph shows a non-linear trend with more possibility of energy saving for increasing COP from 2-3 in comparison with the increment from 4-5 (for COP). Energy recovery from the waste heat sources is one of the major factors which improve energy efficiency of the system. Heat pump is an interesting application as it has the potential to recover energy from low quality energy streams which otherwise will be simply dumped into the environment as waste. 1.2 Heat pump water heater (HPWH) Heat pump water heaters are electronically driven vapor compression cycle based heat pumps which extracts heat from its surroundings and utilizes it for heating up the water for tap water heating and space heating applications. Water can also be heated in conventional ways by using fuel or electricity however the energy efficiency of such a process is too low, for example utilizing fuel to produce electricity and then utilizing electricity to heat up water is not an energy efficient way. Availability of reliable and cheap heat source (for evaporator load) is one of the key factors for successful operation of a heat pump water heater. 3PDF Image | heat recovery from R744 based refrigeration system
