Three-pipe splits

Three pipe breaks

To provide either cooling or heating in any of the fan-coil units in the system requires a supply of hot gas. It is, as a rule, come from a third pipe, taken from the compressor discharge with feed through the valve in the upper part of the inner coil, and drain back to the main line of the liquid. Non-return valve is needed to prevent hot gas flowing back into the compressor. Fan speed control capacitor and if available, the compressor is needed to keep the pressure high enough to ensure the necessary hot gas.

Use of a number of components connected in this way means that they will be integrated in a series circuit, compressors, fans, solenoid valves and others in the framework of a unified management system. Several large producers in the world capable of engineering a complex system of this kind and supplying the appropriate components and training, establish and maintain its...
