Observation: air conditioning usage is growing more and more in the world; the pollution it generates, too

• Who has never dreamt of a bit of fresh air during a heatwave? With global warming and the increase in average incomes in emerging countries, air conditioning is growing very fast all over the world. The resulting sharp increase in electricity consumption will, according to the International Energy Agency, will lead to a doubling of CO2 emissions induced by air conditioning between 2016 and 2050.

• Similarly, in areas with little to no electricity grid, air conditioning is most often provided by generators, that are polluting and noisy.

• TheGYPXE solar air conditioning partly overcomes these problems. Our modular and easy-to-install solution offers access to cool air while avoiding the use of a non-existent or polluting electrical installation. Both domestic and professional premises can, thanks to FREECOLD, now be air-conditioned using the free energy of the Sun!

DC/AC Hybrid solar air-conditioners CMS12.H and CMS18.H

• FREECOLD hybrid air-conditioners operate from two sources of electricity: photovoltaic as a priority and the electricity grid as a backup and when there is no more sun, with an automatic switching of sources without cutting off power supply. They can be used in air conditioning mode as well as in heating or dehumidification modes.

• The photovoltaic panels and the 230V grid power supply connects directly to the outdoor unit. It incorporates a dual MPPT tracker to make the best use of availablesolar energy and minimize the use of the electricity grid.

• Seasonal refrigeration efficiency (SEER), which represents the cooling output of the air conditioner over what it costs on the electricity bill, can reach a factor of 36 W/W or 120 BTU/W according to the European standard EN14825: the electricity bill is reduced, and the planet feels better.

• When the sun shines, hybrid air conditioners operate 100% on the photovoltaic source.

• Energy savings are there, both in summer and winter: in Dakar, where the sun shines 3000h/year, the annual electricity savings amount to 600,000 FCFA (900€) and the investment is paid back in 2.5 years, not counting the comfort of air conditioning during power cuts or the cost of operating a backup diesel generator; in Marseille, where the sun shines for 1000 hours during the heating months and 1000 hours during summer, the annual savings amount to 480€ and the payback time is 4 years。
