Air conditioning consumes a large portion of the electrical energy of the country.  It is very important to local industry, hotels and businesses in general.  Research has been conducted in understanding heat transfer characteristics of heat exchangers used in refrigerant to air heat exchangers.  Micro air conditioning systems used in cooling of electronic equipment.  Peltier cooling for electronic systems.  Geothermal cooling and heating. The rejection of heat into water cisterns or wells to reduce visual impact of air-conditioning units and measure the related performance.  Building of testrigs to measure and analyze airconditioning systems. Inverter air-conditioning and variable flow air-conditioning.  Mainsvoltage effects on the performance of fridges.
