With the increasing demand for refrigeration and air conditioning worldwide, theinterest in alternative processes of cold production which can be supplied from renewable energy sources is also growing. One promising possibility is thermalprocesses. In these processes, thermal energy is used to generate cold. The pump is operated via Vapour jet compressor inrefrigeration and domestic water heating with flat collector are connectedby hoses.
