Absorption cooling and heating systems are one of the most important solar energy applications. Especially if it is used for both heating (winter months) and cooling (summer months. In this study, prototype design and manufacture of a system that can be used for cooling and heating at the same temperature as the solar energy absorption system, which is used as an ammonia refrigerant, was experimentally investigated in order to avoid using an environmentally harmful fluid. Experiments were conducted between 1-31 August 2016 to see the cooling performance of the system and between 1-31 March 2017 to see the heating performance. According to the experimental results obtained, the COP value and the temperature of the room were determined. The solar-energy heating-cooling system is operated for heating purposes; the temperature of the conditioned room is reduced from 19 °C to 31 °C, while cooling is reduced from 39 °C to 23 °C. The generator temperature is measured as 89.1 °C in the summer and 57.4 °C in the winter months when the need for cooling is required. In these conditions, the COP values for cooling and heating of the combined system were found to be 4.621 and 3.283, respectively.
