<div dir="ltr"> Dear list members <div> </div><div><div>The integrated Referigeration and Heat pump for waste energy recovery using biogas gas based ic engine , direct mechanical power input for ic eng is being developed to small milk producing industry by unicamp , Brasil. Tthe project Dr Paul here correctly pointed out , as very important rural enegy demand was well studied by this unicamp university project Sao Paulo.</div>
<div>The master level reserach thesis report page , one can get more detail from the link given here below </div>

</div><div><br></div><div> The water-to-water heat pump was developed for simultaneous production of ice or water frozen </div><div>for cooling of the milk and hot water for cleaning and disinfection of the facilities and </div>
<div>equipment. For operation of the developed heat pump a gas converted engine motor was used, </div><div>allowing the use of the biogas produced by cow manure biodigestion, this provides a low cost </div><div>source of rewable energy, besides the adequate treatment of the animal wastes and the </div>
<div>production of bio-fertilizer of great quality. Three prototypes were assembled, two were </div><div>installed in the laboratory and one in the field, for tests with biogas. The obtained results </div><div>showed a potential of economy of the order of 92% when compared the refrigeration </div>
<div>equipment and the electric heater. When compared with electric energy, the potential of </div><div>economy of the heat pump still was in the order of 65%.</div></div><div><br></div><div> The chacoal , along with produce gas ,syngas or pyrogas based ic engine can be used in stead of biogas. This hotwater and cold ice producing sysrem are very energy efficient with more economical return fir rural area.</div>
<div> the gree trancritical c02 comercial heat pump practiced in japon can be made possible also in serveral tropical country for fruit production .we are open to exchange details the project to make poosible the optimium design to fruit poreservation in remote rural area in Brasil.</div>
<div>Thanking Tom bringing simple boiler steam production alernative , is less expensive , less complex .However small chp steam can have battery inaddtion to ice and chaxoal , making poosible more flexible coproducts </div>
