The arrangement uses a multiple zone regulator with two-way control valves (42,43) in the condensation circuits. A heat exchanger to remove superheating (20) is fitted between the zones of the installation. A two-way manual control valve (42) allows two-way flow between the depart and return of each of the zones. An automatic control valve (43) allows two-way flow between the depart and return collectors of a particular zone. The automatic control valve may be an electromagnetic or thermostatic valve. Regulation of each zone is provided by ambient temperature sensors operating on individual valves between zones. |
