## 1 Introduction  
Constantly, efforts to reduce energy consumption in residential and commercial buildings are mainly due to the fact that such buildings consume up to 40% of the available energy, as shown by [1]. Likewise, authors of [2] ensure that residential, commercial, public and service buildings consume up to 54% of available energy. Various studies have been carried out to reduce energy consumption in residential buildings, and an example can be seen in the work published by [3]. The work present by [1] has shown that, using tubes embedded in the wall, the costs and energy consumption can be reduced. The system was controlled by a specialized program that synchronizes the supply and extraction heat. On the other hand, the author of [4] has shown that, for heating and cooling systems, it is possible to achieve a high share of renewable energies using hybrid systems. Additionally, [5] evaluated a cogeneration and cooling system where heat was obtained through geothermal energy and solar energy, reaching a COP of 3.81. Likewise [6] investigated a technology in district cooling systems, in which it is possible to use renewable energies such as solar thermal energy. Works on hybrid cooling systems have been published by [7], in which the authors have shown that energy saving may exceed 60% when the latent load in the conditioned space is high. As has been shown so far, studies of hybrid compression/absorption cooling systems have already been carried out by different researchers, where electrical energy is used as supply energy. On the other hand, the ability of Stirling engines to transform low-enthalpy solar energy into mechanical energy makes them ideal for application in low-capacity installations. The Stirling engine has been used in compression refrigeration systems for domestic use due to its low noise level and wide range of use of renewable energy sources such as solar energy, as shown by [8; 9; 10]. In the same way, parabolic disk collectors are used with Stirling engines and domestic air conditioning systems, due to their capacity and small size, as shown by [11; 12]. As can be seen in [13; 14], Stirling engine cooling can be produced using solar energy. Absorption refrigeration systems coupled with another refrigeration system have been published by [15; 16; 17; 18]. Solar absorption cooling systems play an important role in energy saving and emission reduction in buildings, as [19] showed. The authors showed that this equipment has better energy saving performance and less environmental impact. [20] proposed a novel solar absorption-compression cascade refrigeration system. The researchers found that energy consumption decreases by 26.7%. The modeling and simulation of hybrid solar absorption/compression cooling systems has been carried out by researchers such as [21; 22]. The authors have shown that the cooling power is strongly dependent on the compressor speed. Whereas, at high temperature and low flow rate of the cooling water in the compression system, the performance of the hybrid system is adverse. Absorption cooling systems powered by solar concentrators are increasingly being studied. Results published by [23] show that traditional single-effect and double-effect absorption chillers have a relatively small operating temperature range, which limits the application of solar systems. For this reason, they propose a novel solar system that integrates photovoltaic and photothermic solar collectors. As far as it has been possible to know, in all the works shown here, flat plate solar collectors or channel concentrators have been used for the power supply and generally for cooling capacities greater than 20 kW. In the present work, a hybrid compression/absorption chiller driven by a Stirling engine and a dish solar collector has been thermodynamically evaluated. A dish solar collector has been chosen over a parabolic trough one, mainly because in the former the Stirling engine can be better coupled to the circular focus.
