New European Energy Code for Chillers

Ricardo Salgdo, C.I Tech – Carrier, Francs

EER & COP belong to the past

Now, and in the future, the focus is on seasonal efficiency

The energy efficiency improvement target strongly influences the heating, ventilation and air conditioning (HVAC) market.

From 1 January 2018, European (EU) regulation 2016/2281 (ENER lot 21) sets out the minimum energy efficiency and information requirements for hot air generators, cooling only and heat pumps air conditioning units, including rooftops, packages & VRF units, comfort chillers, high temperature process chillers and fan coil units.

The presentation will discuss the new code and explains the new standard terms like:

SEER, SEPR, SCOP and Eta.

Corrosion Reduction & Cost Saving for Heating & Chilled Water Systems

Ozgur Hundur, Reflex, Germany, S.A.C.F Engineering

Gas inclusions in heating and cooling-water systems impair the function of facility components and systems with potentially total failure. They reduce the efficiency of energy transfer and lay the foundations for potential corrosion. Corrosion will result in sludge and dirt formation which, in turn, may cause further damage to the water-based system.

Oxygen and hydrogen are mostly responsible for the formation of corrosion phenomena and damages in system components. Hence the short well time of oxygen in the heating system results in the fact that oxygen does not exercise a direct negative effect on heat transfer. However, the indirect effect on the heat transfer may be very significant under certain circumstances. The corrosion particles generated during the reactions may deposit at the pipe interior and, subsequently, act as an insulating layer.

 A frequent repeat of this process due to, for example, constant vacuum in the system, will decrease the heat transfer and cause corrosion phenomena and damage at system components within just a few years of operation. [VDI 2035 (2009)]

Nitrogen, on the other hand, is an inert gas and is not consumed during chemical reactions in the facility system. It remains in the facility water and can continuously accumulate, due to the mechanisms of gas entry that will be discussed in detail below. Compared with pure water as the heat transmitter, nitrogen has poorer thermodynamic properties. The specific thermal capacity of water is, on average, 4 times higher than the one of nitrogen and its thermal conductivity is approximately 20 times higher.

Many years of empirical knowledge as well in-house and external research and studies have proven the major benefits of our technologies in preventing and reducing such undesirable phenomena in facility systems. Practical experience clearly documents that, subsequent to the integration of such technology, the hydraulic system will work properly for the first time and the equipment can consistently function at optimal efficiency. Interlocking with established dirt and sludge separators results in a highly efficient synergy for the optimal operation of water-based heating and cooling-water systems.
