ECA is a water cooled hybrid chiller complete with an evaporative condenser, multiple compressors and a patented plate heat exchanger all within one package.
There are a number of significant features of our system setting us apart from our competitors' units, ie
Rejected heat generated from the refrigerant vapour-compression process is dissipated directly through the patented heat-transfer plate.
Units of our competitors require the rejected heat to be transferred firstly to a water medium and then to a water cooling tower on roof top for heat dissipation.
Our innovative design of how rejected heat is dissipated enables our system to achieve a system COP of 4.5+ for a period up to 10 years. To arrive at our system COP, input power includes power to compressors, cooling water pump and condenser fan.
The main reason why a lot of property owners is reluctant to use a conventional water cooled chiller is a high potential risk of causing Legionnaire disease outbreak.
Working in conjunction with the statutory requirement of chemical treatments, our units can remove almost 100% of Legionella in the condensing water.
Hong Kong Productivity Council (HKPC) was retained by us to carry out tests on System COP and Legionella between 7 August 2017 and 10 October 2017.
In its final report of 23 October 2017, HKPC verifies:-
It is noted that our chiller can achieve 100% efficiency even at 72% part load.
