The amount of energy for air conditioning in the summer time in Mediterranean Area is very high because of hot weather and high temperature values. Solar cooling technology is interesting because strong sunlight covers the cooling requirement. The heat energy from the sun it is available when the demand of electricity has high peaks for the strong use for air conditioning devices. In this work, an analysis by means of NEGST software (New Generation of Solar Thermal System) on a solar cooling and heating system located in the southern part of Italy has been carried out. The building is a Quality Assurance Office of a chemical industry.

The high energy demand on buildings requires efficient installations and the integration of renewable energy to achieve the goal of reducing energy consumption using traditional energy sources. Usually, solar energy generation and heating loads have different profiles along a day and their maximums take place at different moments. In addition, in months in which solar production is higher, the heating demands are the minimum (hot water is consumed only domestically in summer). Cooling machines (absorption and adsorption) allow using thermal energy to chill a fluid. This heat flow rate could be recovered from solar collectors or any other heat source. The aim of this study is to integrate different typologies of solar hybrid (photovoltaic and thermal) collectors with cooling machines getting solar trigeneration and concluding the optimal combination for building applications. The heat recovered from the photovoltaic module is used to provide energy to these cooling machines getting a double effect: to get a better efficiency on PV modules and to cool the building. In this document the authors analyse these installations, their operating conditions, dimensions and parameters, in order to get the optimal installation in three different European cities. This work suggests that in a family house in Madrid, the optimal combination is to use CPVT with azimuthally tracking and absorption machine. In this case, the solar trigeneration system using 55 m 2 of collector area saves the cooling loads and 79% of the heating load in the house round the year.

“…The interaction between solar collector field and cooling system is generally the most critical. 74 In fact, the efficiency of the collector field decreases with operating temperature, while the efficiency of the thermally driven cooling process increases. Differently designed collectors operate at different temperatures, so it is important to match the collector type with the chiller type.…”

Solar district heating and cooling: A review

et al. 2017

Summary Both district heating and solar collector systems have been known and implemented for many years. However, the combination of the two, with solar collectors supplying heat to the district heating network, is relatively new, and no comprehensive review of scientific publications on this topic could be found. Thus, this paper summarizes the literature available on solar district heating and presents the state of the art and real experiences in this field. Given the lack of a generally accepted convention on the classification of solar district heating systems, this paper distinguishes centralized and decentralized solar district heating as well as block heating. For the different technologies, the paper describes commonly adopted control strategies, system configurations, types of installation, and integration. Real‐world examples are also given to provide a more detailed insight into how solar thermal technology can be integrated with district heating. Solar thermal technology combined with thermally driven chillers to provide cooling for cooling networks is also included in this paper. In order for a technology to spread successfully, not only technical but also economic issues need to be tackled. Hence, the paper identifies and describes different types of ownership and financing schemes currently used in this field.
