– The water circuit is equipped with a three way valve which allows regulating the by-
pass of the gascooler.
– A thermostatic control valve allows controlling the water flow which passes through
the intercooler on the LT versions. This valve operates by measuring the temperature
of the refrigerant on the CO2 outlet of the heat exchanger.
– When dimensioning the water circuit, the installer must take into account the
pressure losses of the water pipes and the exchanger(s).
