All-in-one Air Source Heat Pump Water Heater 350L & 420L

In an all-in-one heat pump water heater, the heated refrigerant is usually
conveyed through a heat exchanger that’s wrapped around the outside of the
tank, under the insulation. The refrigerant heats the tank by conduction,
transferring heat from the condenser coil through the tank shell, to the water
inside.
Heat pump is a device in which the refrigerant R134a is continuously changing
the shape from gas to liquid. It pumps out the solar energy from the air in the
room and together with electrical energy consumed by compressor it gives out
the total heating capacity which is accumulated in the water storage tank.
Evaporator is an air-refrigerant heat exchanger. In the evaporator the
refrigerant is vaporized at low pressure and relative low temperature. Because
of vaporization the heat transfer form air to refrigerant starts. Vaporized
refrigerant comes in the compressor where the pressure goes higher and also
the temperature. From compressor the vaporized and high temperature steam
goes in the condenser (refrigerant-water) where again the heat is transferred from refrigerant to water. The
refrigerant is now in liquid shape idler high pressure. After it flows thought the expansion valve it reaches the
basic shape and he process goes around again. The circuit is in process until the water temperature in the water
storage tank reaches the set point.
