How Does It Work - Kingspan AEROMAX PLUS AIR SOURCE HEAT PUMP PACKAGE Homeowner's Manual

HOW DOES
IT WORK?
Aeromax Plus Air Source Heat Pumps provide thermodynamic heating by
means of a vapour compression cycle. In the same way that a fridge uses
refrigerant to extract heat from the inside to keep the food cool, air source heat
pump extracts heat from the outside air, and uses it to heat the home through
radiators, underfloor system or provide domestic hot water. It can extract heat
from the air even when the outside temperature is as low as -20°C.
OUTSIDE AIR
Every air source heat pump
has four main parts:
1. Evaporator
2. Eompressor
3. Condenser (heat exchanger)
4. Expansion device
Although Aeromax Plus is powered by electricity, when it is installed and designed
correctly can often result in the system costing less to run than systems heated
by oil, LPG, electricity or coal. Your heating costs will depend on how you use
your heating or hot water and the temperature of your radiators. Aeromax Plus is
cost-effective to use all year round, but you can ensure it is at its most efficient by
running your radiators or underfloor heating at lower temperatures.

1. EVAPORATOR
The evaporator collects heat from
the outside air, which is then drawn
into the unit by the fan through the
evaporator fins and expelled through
the front grille. The evaporator has
liquid refrigerant passing through
it, which is at a considerably lower
temperature than the outside air,
therefore the air gives up its heat to
the refrigerant, which then vaporises.
2. EOMPRESSOR
This preheated vapour now travels to
the compressor where it is compressed
and upgraded to a much higher
temperature.
3. CONDENSER (heat exchanger)
The hot vapour now enters the
condenser where it is surrounded by
water from the heating system. The
heat is given up to the cooler water
and the now cooler refrigerant returns
to its former liquid state but still under
high pressure from the compressor.
4. EXPANSION DEVICE
This high pressure is then released
by passing the liquid through the
expansion device and from there it
returns to the evaporator and the cycle
starts again.
