Hi-FLEXi W Series Heat Recovery can keep simultaneous cooling and heating from one system. And it has a new switch box, which is designed to improve energy efficiency. The products are more flexible to meet users’ demands.
With 2-stage heat recovery from both refrigerant side and water source side, the heat recovery system realize energy saving at the greatest extent. Simultaneous cooling and heating in one system could be achieved.
Heat exhausted from indoor unit in cooling mode could be transferred to the units which is in heating mode.
The outdoor unit of cooling mode exhaust heat into water , and the other outdoor unit of heating mode absorb heat from water. So the heat recovery between outdoor units could be achieved via the water pipe .
