Adsorption heat pumps for providing coupled heating and cooling effects in olive oil mills

Abstract

The olive oil mill wastewater presents serious environmental threats. In this study, adsorption heat pumps utilizing zeolite coatings were proposed for olive oil mills as a helping tool for the treatment of wastewater, as well as for providing a cooling effect, which may especially be useful to prevent thermal deterioration of the olive oil. The performance of a heat pump using two adsorbers operating with waste heat was determined for different operating conditions. It was established that a sufficiently high amount of olive oil wastewater might be treated in such a system when a suitable source of waste heat is used for heating the adsorbers of the heat pump.
