The presented water chiller has a non-typical configuration consisting in the use of remote air condensers. The need for this is caused by the requirements of the particular application. The main features of the system are:

• two completely independent refrigerant circuits connected to a common hydraulic system in order to ensure maximal operational reliability

• high efficiency scroll compressors

• brazed plate heat exchangers specially optimized for use with R410A

• air condensers with EC fans providing low condensation temperature, minimal power consumption and stable system control

• electronic expansion valves (EEV) that provide optimum use of the evaporator heat transfer surface and precise control of the refrigerant mass flow rate in accordance with the dynamic working conditions

• integrated heat recovery system for domestic hot water heating

• optimized design that provides fast and efficient execution of all service operations

• web-based interface that allows remote control and monitoring of all operating parameters, diagnostics and automatic notification
