How it works

The basic principle of how Solar Air Conditioning works:

Refrigerant is circulated by the compressor (1), to the solar panel (2), where it is heated by solar thermal energy that has been collected and stored in the panel. The heated refrigerant is now hot and at high pressure due to expansion. It enters the condenser (3), and the condensation process is now enhanced by the extra large condenser coil and the high temperature and pressure of the refrigerant. The result is that the condenser coil fills with refrigerant that has changed phase completely into liquid instead of aerated fluid as in regular air conditioners. This fluid backs up behind the choking device (capillary), (4), as it changes phase back to vapour it absorbs energy (cools), as it passes through the fan coil or evaporator(5). The cooling effect is rolled over into the air being circulated by the fan from the area to be cooled. The low pressure vapour returns to the compressor to repeat the cycle.

This fluid backs up behind the choking device(capillary), (4), as it changes phase to vapour it absorbs energy (cools), as it passes through the evaporator(5). The cold temperature is rolled over into the outside air as it is drawn through the coil by the fan. The low pressure vapour returns to the compressor to repeat the cycle.
