The invention relates to a new solar thermally driven system that meets the heating and cooling demands of buildings. The system consists of a reversible absorption cycle which operates as a single effect absorption cycle in the cooling mode and as a heat transformer in the heating mode. Components of both cycles are the same, only the flow direction inside the system changes. In thermally driven systems, solar thermal collectors convert solar energy into thermal heat which can be used to run a thermally-activated device. Different types of thermally driven systems are available on the market, but among them, absorption systems are the most mature technology and are commercially available. The thermal collectors mostly used in solar absorption installations are flat plate or evacuated tubes. These thermal collectors produce hot water to drive the absorption machine in summer and produce chilled water. However, the hot water temperature obtained in winter with these solar collectors is too low to directly feed conventional heating systems but also is too low to drive the absorption machine in order to produce a higher temperature water stream to feed the heating system. So, in winter the hot water produced in the thermal collectors is heated up in a boiler before to feed the heating units. The invention proposes a new reversible solar driven absorption machine that in summer it would work as an absorption chiller, as the machines that we can find on the market today, but in winter it would work as a heat transformer. As heat transformer the absorption machine cycle can be driven with a heat source temperature of 40 °C to produce hot water at 60°C at an ambient temperature of 0°C. Furthermore, the lower the ambient temperature, the lower the activation temperature of the machine and higher the machine heating power. Components of both cycles are the same, only the flow direction inside the system and the connection with external devices changes. To allow the reversibility of the equipment and its operation in winter a new working pair, ammonia/lithium nitrate, has been selected because no rectifier is required and it does not present problems of refrigerant freezing at low condensing temperatures when the cycle operates as a heat transformer.

The Group has been working in the development of technologies that integrate the management of the entire set of electronic devices existing in a home. The group is specialized in providing home automation solutions to people with mobility problems, such as elderly people, children or disabled people. It also is experienced in the development of computer systems for energy management of housing. Innovative aspects The research group has significant experience in developing automated systems for all types of environments. The possibility to develop specific integration solutions for any type of device used in a home (lighting, security system, wireless appliances and entertainment equipment, sensor network environment, etc.). They can also integrate all kinds of control systems and power generation to facilitate saving and energy efficiency of buildings. The group is able to develop new solutions based on the requirements and user needs. Main advantages of the technology The technology developed by the research group is established in the project metalTIC - Digital Home. This project, conducted for the Federation of Employers of the Metal of the Province of Alicante (FEMPA), has been the design and development of a set that simulates a house with the latest innovations in TICC to provide services at home. The 50 square meters house has a living room with kitchen, bedroom and bathroom, showing key concepts such as energy control, monitoring and security, comfort and leisure, communications, accessibility and management.
