HOW DOES THE HEAT PUMP MODULE WORK?
A Heat Pump uses complex thermodynamic principles to extract energy from
ambient air and transfer this energy to water that is in contact with the unit’s
immersed heat exchanger. The Heat Pump’s operational principles are similar
to those used in a normal domestic refrigerator except in reverse. In a
refrigerator heat energy is drawn from inside the refrigerator (making things
cold), concentrated by the compressor then dissipated to the atmosphere via
the condenser coil located on the back of the refrigerator cabinet.
For an Airoheat system outside air is drawn into the unit and across an
evaporator coil by a fan. The evaporator coil captures the energy in the air
and transfers that to cold liquid refrigerant, contained inside the evaporator,
causing the refrigerant to increase in temperature and evaporate into a warm
gas.
The warm gas on exiting the evaporator passes into a compressor where
compression causes the temperature of the gas to increase further, becoming
a superheated (hot) gas.
The superheated gas is pumped, from the compressor, to a water immersed
condenser coil where it gives up its heat energy to the water. When the
superheated gas gives up energy it condenses back to a liquid, and on exiting
the condenser coil, it passes through an expansion control valve (TX valve).
The TX valve acts as an automatically adjusting tap that controls the amount
of liquid refrigerant that is allowed to pass, once more, into the evaporator.
This is necessary to constantly match the amount of liquid entering the
evaporator to the available energy in the air passing through the evaporator
so that the entire liquid refrigerant, that enters, evaporates and only exits as a
gas.
HOW DO I OPERATE THE SYSTEM?
The operation of your Heat Pump Water Heater is fully automatic so you only
need to connect the water and electricity supply and then turn on the
electricity.
The Heat Pump module is electrically connected to the storage tank and will
start automatically when the water temperature in the storage tank falls below
55°C and continue to run until the water temperature of the complete tank has
been increased to 60°C or slightly above. To condition the unit properly allow
the heat pump to go through one heat up cycle, before use, in that case allow
24 hours before using the hot water.
