Gas heat pump air conditioning
A gas heat pump (GHP) air conditioning system is a system powered by an engine using gas as a fuel that drives a
compressor. In this way stable heating operation can be achieved with low electricity consumption.
However, same as for an automobile engine, periodic inspection by a specialist serviceperson is necessary.
d
Periodic maintenance contract
In order that a GHP can perform in accordance with the speci
fi
cation, periodic inspection is necessary. Particularly
as the operating hours of an air conditioning system are long compared with the running hours of an automobile,
more reliable inspection and servicing is necessary. In order to use the air conditioning system stably and for a long
time, we recommend a “Periodic inspection contract”.
