The Panasonic air conditioning ECOi high efficiency, high output solution for chilled and hot water production. Ideal for residential, commercial and industrial hydronic applications which require high efficiency, high power output water heating and cooling. The Panasonic ECOi Water Heat Exchanger (WHE) indoor unit heats or cools the water or sub glycol mix to the set temperature via the external heat pump outdoor chiller condensing unit. Operation and control of the ECOi water chiller / heater is easily set with the easy to use and renowned CZ-RTC4 timer remote control and with a Wi-Fi control option, and many other commercial / industrial control options.
The Panasonic air conditioning ECOi has a energy-efficient capacity control system which moderates the inverter control outdoor unit and the unique 4 way valve which operates with a counter-flow fluid circulation in heating and cooling fluid circulation on both lines of the refrigerant flow which optimizes efficiency. The stainless steel plate heat exchanger with anti-freeze protection control and a optimized heat exchanger design to increase drastically the heat transfer efficiency. Liquid receiver to outperform the functionality of the WHE and long pipe run projects. The new range of Panasonic ECOi water chillers and heaters include the new electrical panel with advanced control algorithm, this includes a auto change-over option between heating and cooling operation where required with a 1-2 DegC drift meaning a set temperature can be linear whatever the users application requires.
