Characteristics of REMKO inverter heat pumps
Heat source outdoor air
An air/water heat pump absorbs
energy from the outdoor air as its
heat source and transmits this to
the heating system.They have the
following advantages over a brine/
water and water/water heat pump
system:
Split AC unit
The REMKO inverter heat pump is
a so called split AC unit. This means
that is consists of an outdoor unit
and an indoor unit, both of which
are connected via refrigerant-carry-
ing copper pipes. This means that
there are no water-carrying pipes
laid from the indoors to outdoors
which need to be made frost proof.
The outdoor unit contains only the
condenser, the evaporator and the
expansion valve. This means that
the outdoor unit is considerably
smaller.
The indoor module contains the
liquefier for the circuit and the con-
nections for the heating network.
The heat pump's condenser is
equipped with a requirement-de-
pendent speed control system. The
power control on conventional heat
pumps provides only two states,
either on (full power) or off (no
power). The heat pump switches
on when the temperature drops
below a certain level and switches
off again when this temperature
has been reached.
This type of power control is
extremely inefficient.The power
control on REMKO'S
inverter heat
pumps is continuously modified to
the actual heat requirement.
The electronics system has an
integrated frequency converter
which serves to modify the con-
denser speed and the speed of the
evaporator fan as required. The
condenser works at a higher speed
when under full load as when it
is under partial load. The lower
speeds ensure a longer operational
lifetime for the components, im-
proved coefficient of performance
and lower noise.
Lower speeds also result in lower
energy consumption (electricity).
■ Can be used everywhereAir is
available everywhere in unlim-
ited quantities. For example, no
wells are required.
■ No excavation work requiredNo
large areas are required for soil
collectors.
■ EconomicalExpensive drilling is
not required.
■ Excellent value for money and
simple installation
■ Particularly suitable for low-
energy houses with low inlet
temperatures
■
Ideal for bivalent operation, in
order to save energy
