Renewable Energy #3: Solar (PV) Air Conditioning
Posted: Fri Mar 24, 2017 4:47 pm
Everyone who installed already a photo-voltaic system in order to have
electricity from the own roof (net-metering) produce usually enough kWh to
run air conditioning as well with no extra costs. But there are many houses
without the space for 10-12 or more panels to install such a system.
As Air conditioning is the largest consumer of electricity an alternative to the
above would be nice. For example an air con system which runs 90% with
the power of the Sun from 3-4 PV panels in daytime. With the built-in inverter technology
the system produces cold or hot air (Winter setting) the same way like modern air cons do,
but with nearly zero electricity consumption. Available in several sizes from 12000 BTU
to 24000 BTU. If one switch it on as soon as the Sun is shining and let it run all day it will
cool down (or heat up) the wider area the indoor unit is installed. Walls, floors, furniture etc
store the energy for a while after sundown. As system is connected to the grid as well one can
switch it back on at night if necessary. It will be not cheap (ca 2700 Euro) as there is more
installation work involved and panels, mounting materials etc. There is no extra inverter necessary,
and no batteries either (still problematic with e-cars).
I think this would be another product for our sunny Cyprus as the Sun shines the most when
one needs cooling...
