Abstract: Integrating the vapor generator/separator of an absorption machine and the solar collector field is proposed as a means to reduce the cost and complexity of solar cooling and heating facilities. In order to further enhance the competitiveness of these facilities, some previous work on hybrid and combined absorption cycles is analyzed so that the proposed integration can be configured using these cycles. As a result, a single machine could in addition to pump heat can produce electricity and even consume it for fulfilling the cold and heat demand from the user when solar is not enough, this avoiding implementing a vapor mechanical compressor.
