0. BASIC OPERATION PRINCIPLE
As we know with our experience, the natural flow of heat, which
moves from a higher to a lower temperature source. The heat pump
can transfer heat from a lower temperature source to a higher
temperature source with high efciency.
The advantage of a heat pump water heater is that it can supply
more heat energy, normally 3 times than input electricity power by
extracting the heat from ambient atmosphere in a free charge way
to Sanitary Hot Water, compare to the traditional water heater, such
as electric water heater or gas burner water heater, their efciency is
normally less than 1, which means it will dramatically cut off the bill
of family daily SHW by the application of heat pump water heater,
following data will show more details.
Power consumption comparison under the same condition to heat 1
ton water from 15˚C to 55˚C
The equivalent heat load Q=CM(T1-T2)=1(kCal/kg*°C)
X1000(kg)*(55-15)(°C)=40000kCal=46.67kW*h
