REMKO inverter technology
The heat pump's compressor is equipped with are
equipped with a speed control system, as needed.
The power control on conventional heat pumps
provides only two states, either ON (full output) or
OFF (no output). The heat pump turns on below a
specified temperature and turns off when this tem-
perature is reached. This kind of heat regulation is
very inefficient. Heat regulation in the REMKO
inverter heat pump is modulated to the actual need
and is adjusted to suit actual needs. The elec-
tronics system has an integrated frequency-con-
1/3
When it is switched on, the inverter only requires
one-third of the time of conventional systems

Function of the heat pump
A heat pump is a unit which makes use of a
working medium to absorb heat under low temper-
atures and transports this heat to a place where it
can be of use for heating purposes. Heat pumps
work according to the same principles as a refriger-
ator. The difference is that heat, the by-product of
the refrigerator, is the goal of the heat pump.
The main components of the cooling cycle consist
of an evaporator, a compressor, a condenser and
an expansion valve. In a finned evaporator, the
refrigerant evaporates both because of lower pres-
sure and because of lower heat-source tempera-

verter which serves to modify the compressor
speed and the speed of the fan as required. The
compressor works at a higher speed when under
full load than under partial load. The lower speeds
ensure a longer operational lifetime for the compo-
nents, improved coefficient of performance and
lower noise. Lower speeds also result in lower
energy consumption (electricity) and longer service
life. I.e.: inverter heat-pumps will run practically
throughout the heating season. In all, the highest
efficiency possible.

tures through absorption of energy from the envi-
ronment. In the compressor, the refrigerant is
brought to a higher pressure and temperature by
the application of electrical energy. Next, the hot
refrigerant gas reaches the condenser, a plate heat
exchanger. Here the heat gas condenses, transfer-
ring heat to the heating system. The liquefied
refrigerant then expands and cools in a flow regu-
lator, the expansion valve. Then the refrigerant
flows into the evaporator once more and the cycle
is complete.
