Increased global energy consumption and CO2 emissions are expected to increase by almost 60% in 2030, compared to the early 2000 (Ghafoor, et al 2014). One of the biggest factors of increasing energy consumption is influenced by the need for water cooling or air conditioning. The need for water cooling/air conditioning is influenced by an increase inthermal loads, as well as an increasingly diverse form and capacity of a building. In addition, the increase in the need for water cooling/air conditioning is also influenced by peoples behavior which requires comfort in the temperature of a building, especially for people who are in tropical climates, for example Indonesia. This behavior becomes a habit, so that today the community is very dependent on the use of air cooling/air conditioning. To answer the problems in the use of water cooling/air conditioner and the utilization of solar energy, the technology of the Solar Air Conditioner is based on the Desiccant Cooler System. In its use, the system is able to cool the temperature in a room as needed, by utilizing solar radiation. The system consists of components Desiccant, Heat Exchanger, Evaporative Cooler, and Solar Thermal Collector, and uses working fluid (water). However, in the application of this system Solar Air Conditioner there is no air exhaust mechanism as a result of cooling in the room, the cooled air is confined indoors so that if left for a long time it will make the air unhealthy. In US Pat. No. 6.513.339 dated February 4, 2003 explained about Solar Air Conditioner in a closed system that uses a desiccant fluid system incooling evaporative cooler, but the system has closed air circulation which causes indoor air quality poor. The innovation that we offer here is in the design of the Solar Thermal Air Conditioner system, there are additional ventilation components that can be controlled, so the system can also function to circulate the air inside the room. In addition, the design function of the Solar Thermal Air Conditioner also emphasizes the saving of electricity consumption, because the largest energy consumption is obtained from thermal energy from sunlight. The result is using components Solar Collector, Heat Exchanger, Desiccant Wheel, and Evaporative Cooler, controlled ventilation, the system is able to condition and circulate air by reducing electricity consumption.
