Multi-purpose units, designed for applications with simultaneous and independent demand for hot and cold water production.
In particular, this occurs for all systems that use 4-pipe terminals, such as for example dual aspect buildings, buildings with large glazed surfaces or high-insulation buildings with non-homogeneous crowding levels.
In particular, this occurs for all systems that use 4-pipe terminals, such as for example dual aspect buildings, buildings with large glazed surfaces or high-insulation buildings with non-homogeneous crowding levels.
The 4-pipe multi-purpose unit is able to meet simultaneous and independent heat loads of opposite sign, with the advantage of working in heat recovery operation: whenever there is a simultaneous demand for cooling and heating, the multi-purpose unit will work in recovery mode, and move the thermal energy from rooms that need to be cooled to those that need to be heated. If the two heat loads are not balanced, then the controller works in mixed mode to recover as much thermal energy as possible and use the air exchanger as heat source with which to exchange the missing amount of capacity for meeting both demands of the system.
The 4-pipe multi-purpose unit can therefore work indirectly all year round to meet all the thermal and cooling energy demands of the system and is therefore an alternative to conventional systems based on the chiller/boiler combination with the additional non-negligible advantage of waste heat recovery. Depending on the various scenarios that can occur over the span of a day, the multi-purpose unit can work with different modes and change from one to another fully automatically.
