march, 2015 - heatcraft australia has expanded its range of energy efficient commercial chillers with the introduction of lennox aqua4 polyvalent air cooled chiller and heat pump.

heatcraft hvac business manager mark esdaile, said a market comparison has shown that the lennox aqua4 is on average 13 per cent more energy efficient than equivalent competitor models for cooling. it is also quieter than any other four pipe system in the australian and new zealand market.

the lennox aqua4 is a cost effective alternative to vrf systems that offers simultaneous or independent heating and cooling from the one system.

“it is especially suited to commercial buildings, hospitals, hotels and public buildings that require different zoning and load requirements,” esdaile said. 

“the simultaneous demand for heating and cooling during the year is increasingly common. today’s commercial buildings often include areas dedicated to different functions and have high variable heat loads.”

the simultaneous and independent cooling and heating is achieved by the use of two independent refrigerant circuits connected by four hydraulic pipes.

edrive technology

in a water system, the pump is one of the main energy consumption items. the energy costs of pumping can represent more than 20 per centof the total energy cost of a chiller. lennox has addressed this with the edrive variable speed pump technology, present in both neosys and ecolean.

at full load, edrive automatically controls energy costs via an electronic adjustment of the pump curve. at partial load, edrive automatically reduces the chiller pump speed. during shutdown periods, the chiller operates at minimum speed and on starting edrive acts as a soft starter minimising start-up current.
