Solar — Assisted air — Conditioning for energy saving in a feeder in Sulaimani governorate

Air conditioning is the dominating energy-consuming service in buildings in many countries. In many regions around the world demand for cooling and heating of indoor air is rising due to increasing comfort expectations and growing cooling loads. Kurdistan region has a very sunny climate with high demand for air conditioning. Conventional air conditioning impacts upon the electricity grid and threaten the environment to affect life quality of people. The electricity grid increasingly faces the danger of overload due to air conditioner use during the hot summer days which would cause essential power service disruption. However, solar assisted air conditioning offers an alternative way to meet the increasing cooling and heating demand in buildings of the region in an energy-efficient way. Accordingly, this paper investigates the technical feasibility of using a typical heat pipe evacuated tube collector system with small and medium scales for Electric Distribution Directorate Building in Sulaimani and its impact on terminal voltage, active and reactive power losses on the feeder. The working principles, system suitability for solar cooling and heating have been simulated with the help of Excel and ETAP 11.0.0 software.
