THE WORKING METHODE OF THE HEATPUMP

4.1.

Operation principle

HB300 heat pump water heater is seemingly similar to traditional electric hot
water tanks. During its normal operation cycle, HB300 connected to household
pipeline and electrical power system does not use as much electric power for direct
heating of water as the traditional electric hot water tank does, but rather, it uses
energy in a more rational and efficient way, reaching the same result with an energy
use of less than 70% as compared to the traditional electric hot water tank.
Heat pump is named by the fact that it is able to transfer heat from a heat
source of lower temperature to a heat source of higher temperature, which means it
turns natural flow of heat, which is transferred from a heat source of higher
temperature to a heat source of lower temperature. The application of the heat pump
brings the benefit that it is able to transfer more energy (in form of heat) than the
energy it takes for its operation (in form
of electric power). This way, heat pump is able to extract energy from heat sources
existing in its environment without "expenditure", depending on the type and
availability of the heat sources.
HB300 heat pump water heater extracts heat from stuffy internal air to be
refreshed, thus it adds to the efficiency increase of water heating. It is possible to
select among several different configurations to use environmental air, which
provides multilateral application of the appliance besides different operational
conditions.
