This month, January
2005, I am starting a series of newsletters related to energy efficiency in
industrial refrigeration.
In these newsletters, I want to share my
experience and my knowledge about energy efficiency in industrial refrigeration,
because I found a shortage of information regarding this issue. If you have any
questions, regarding energy savings in industrial refrigeration, please contact
me.
Why should I save
energy?
- Price of electrical energy is going up. Revenue can come
and go with economic trend. Energy cost, however, is always there and usually
increasing. Energy prices inCanada are
cheaper than in Europe and
USA. We will
have to catch-up with these countries in energy efficiency, as energy prices
move higher in
Canada.
- Canada
has signed Kyoto agreement on global warming.
According to this agreement we have to reduce emissions of green house gases
to 6 % below their 1990 level each of the five years from 2008 to 2012. But
today our emissions are 20 % higher compared to 1990, so we have to save 26 %.
This is a very significant number, but it is achievable for industrial
refrigeration.
- Ontario
provincial government is planning to close all coal electrical station by
2007. To keep light on, they want to replace these stations and implement
conservation measures. Conservation would be a cornerstone of the plan and the
target is 5 % of energy savings.
These reasons show how important it is to
save energy in our days. In industrial refrigeration, energy use can often be
reduced by as much as 30 %.
Why should I hire energy efficiency
consultant?
I heard several times from potential
customers, that they have a good contractor and they don’t need energy
efficiency consultant to save energy.
Unfortunately, most industrial
refrigeration design firms or contractors have little experience, expertise or
interest in maximizing energy efficiency. Every professional engineer designs a
refrigeration plant for maximum refrigeration load and extreme ambient
conditions (design conditions). But refrigeration plant is running at these
conditions less than 1 % of total operating time.
How should you run the plant
efficiently for the rest 99 %? This is an area where energy efficiency engineer
can help you. Experienced consultant shall asses the energy efficiency of
existing equipment, identifying each energy efficiency opportunity and outlining
each of the viable energy efficiency upgrades.
