Heat Pumps
AEROMAX PLUS
AIR SOURCE HEAT PUMPS
Our range of
Kingspan Aeromax Plus Heat Pumps
has been designed specifically for
use in North European climates. Operational to -20°C, they provide water temperature up
to 55°C – 60°C. They work efficiently with both radiators or underfloor heating systems,
delivering typical comfort space heating between 35°C and 55°C. With their exceptionally
small footprint they are probably the most compact units in today’s market.

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.

Every air source
heat pump has four
main parts:
2.
This preheated vapour now travels
to the compressor where it is compressed
and upgraded to a much higher
temperature.
3.
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.
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.
Basic Concept of Heat
Pump Technology
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.
Heat pump uses a small amount of energy
to move heat from one location to another,
for every 1kW of electricity consumed by
the heat pump it can produce 4kW of heat
energy. This gives an efficiency of up to
400% sometimes stated as a Co-efficient
Of Performance (COP) of 4:1.
