Abstract

Solar energy is one of the most well known green sources of energy in the world. It has many applications such as water heating, space cooling, solar drying and etc. This research presents a feasibility study of a small scale air-conditioning unit consists of an aqua-ammonia ejector absorption system equipped by evacuated solar thermal collectors. Absorption system provides cooling during hot season and solar collector provides heating during cold season directly. The dynamic simulation has been performed using TRNSYS 16 environment. The TRNSYS is an energy system simulation software. It's specialized in the field of renewable energy. The solar fraction is 10% to 36% for collector area of 10m2 to 40m2. The economic analysis has also been conducted. The electrical cost less than 0.45 USD/kWh is not economical and leads to negative saving.
