High Efficiency, Superior Model
Hitachi SET-FREE WS series central air conditioner combines inverter drive technology with water source heat working technology. All the features of the optimization design ensure a high COP value over a wider operating range in cooling and heating.
Simultaneous Cooling and Heating, More Energy Saving in Heat Recovery System
The need for simultaneous cooling and heating has emerged as a result of the increasing number of large modern buildings with their complex structures, functions and more comfort demands, especially in seasonal transitions or in winter months. In a conventional central air conditioning system, more energy is consumed when heating and cooling are carried out at the same time.
