Erp Energy Label Air Source Water Heater Power World DC Inverter
Heat Pump With DC Inverter Compressor
The Power World product range is very diverse and fully tailored to
our customers' needs. From detached single-family homes to
commercial buildings - PowerWorld heat pumps cover groundwater and
water/water with heating outputs from 7kW to 115kW and air source
heat pumps from 2kW to 110kW.
Energy-saving, cost-effective, sustainable and with a guaranteed
future – those are the principal features associated with a modern,
properly installed heat pump. OCHSNER heat pumps offer critical
advantages for heating, cooling and hot water heating. And the
system is extremely simple:
The heat pump uses ambient heat which is stored in the air, water
and ground – natural heat sources. Much of this environmental
energy comes from the sun, but heat also comes from deep within the
ground. These renewable energies are heated from a low to a higher
temperature level by means of sophisticated technology, making them
suitable for heating purposes.
How Do The DC Inverter AIR – WATER Heat Pumps Operate
The whole system consists of the external and internal unit. The
external unit with evaporator and fan is placed outside and it
sucks ambient air. At that moment, liquid coolant is injected to
the external unit via the expansion valve. Flowing air heat is
transferred to the coolant in the evaporator. So its state changes
to gas state. The coolant in gas state proceeds to the internal
unit, concretely to the compressor where it is pressed. While the
coolant is pressed in the compressor, the pressure increases and so
increases the temperature. In this way, the original low-potential
heat of the coolant taken from the external air increases to the
level suitable for heating or water heating. The coolant of high
temperature then proceeds to the condenser and transfers heat to
water of lower temperature there. In this way, the coolant is
cooled down and condensation occurs. Heated water that accepted
heat from the coolant goes to radiators or floor heating and emits
the heat to a room. The condensed coolant passes via the
sub-cooling exchanger to the external unit and the whole cycle
Exchanger (high-pressure part), the gas cools down and condensates
2. Expansion valve, the liquid expands and cools down
3. Evaporator (low-pressure part), the liquid evaporates and
changes its state to gas
4. Compressor, the gas is pressed and it heats up
Red section = high pressure
Blue section = low pressure
Heat pumps operate on the same principles as a refrigerator -
except that the process is reversed. A heat pump extracts some of
the thermal energy stored in the ground or in the groundwater (this
stored energy is constantly replenished) and converts it into space
The system works all year round. Below a certain depth the ambient
temperature and the temperature of the groundwater are no longer
affected by seasonal changes.
During the summer, your Weider heat pump can be combined with an
additional cooling set (optional accessory) to reduce the room
temperature by around 2-4 °C. The water in your underfloor heating
system absorbs the thermal energy, and this is then dissipated into
the ground via the heat pump. Only the economical recirculation
pumps need to run for this to work, so the compressor can remain
switched off and does not consume any electricity.
DC Inverter Heat Pump Water Heaters Features:
