Renewable energy technologies in air conditioning: State of the art and perspectives.

Number: pap. n. 1846

Author(s) : LAZZARIN R.

Summary

An increasing demand for space cooling is expected due to the economic growth in developing countries (often with hot climates), to the increasing use of electric appliances in homes and offices that increase internal gains and to the global warming. Just global warming suggests to provide larger fractions of space cooling using renewable energy technologies.
A first rough classification considers passive (or almost passive) and active technologies. The former include evaporative cooling, radiative cooling, natural ventilation, the use of aquifers or of the ground. The latter mean mainly solar cooling, but also cooling using biomass, considering renewable technologies for air conditioning only when the renewable energy is directly applied to the cooling plant and not for producing electricity for the grid. The technologies are often well experimented and some of them are approaching or even reached the economic parity with the conventional air conditioning systems.
