DAIKIN MULTIPURPOSE CHILLER EWYD-4Z B

A 4-pipe or multipurpose chiller is essentially a hybrid solution allowing to provide buildings with both chilled water and hot water at the same time.

For a long-time HVAC projects have faced the need for simultaneous cooling and heating installing boilers and chillers and having them operate at the same time. This system layout still makes sense for many projects. In fact, every HVAC project has peculiarities that need to be considered, but a multipurpose unit can be a viable solution that should always be considered as an option.

4-pipe or multipurpose chillers allow buildings to operate without the need for additional boilers. These systems are capable of simultaneously providing constant chilled water for air-conditioned areas, constant hot water for heating circuits, and a proportional amount of sanitary hot water.

All that is possible thanks to a design that allows the unit to manage two separate loops – one for chilled water and the other for hot water.
