This research aims to improve the performance of a solar-absorption-air-conditioning installation, through the design of a simple control system, for easy implementation. This installation was designed by E. Quintana (2012) in TRNSYS, a systems simulation program. With the vision of a future implementation, a performance analysis of the absorption Chiller was carried out based on the results of the simulation from the previous work. It was found that its performance does not reach safe operating ranges within the daily operation time, every time the system starts. Based on this, the proposed research includes the design of a control system to improve the performance of the absorption chiller, from the safety point of view of the latter and the reduction of the electrical consumption of the installation. The safe operation of the Chiller is achieved when it and the whole system, operate within the nominal ranges indicated by the manufacturer. The results indicated that the parameters to be optimized are the temperatures of the water entering the generator and the thermal accumulator. Using the On-Off and Feedback differential control strategies, the results of the simulations show that the first objective was reached. In contrast, the second, could not be achieved, since the energy from the solar source fails to meet the needs of the Chiller within the daily operating time. |
