TRIGENERATION ? SOURCE OF ENERGY SAVING IN LOW-POWER ENERGETICS FOR AGRICULTURAL PRODUCTION

Development of small agricultural production outside the settlements is constrained by the technical difficulties of implementation and cost of centralized power and heat supply. Low power energetics is capable for combined production of electricity and heat in a cogeneration system. Further energy efficiency increase of a small power plant is provided by trigeneration, wherein one kind of primary energy is transformed simultaneously in the three beneficial effects: electricity, heat and cold, which are equally needed to agricultural production. In the particular example of the farm, which has quarters, greenhouse and cold storages, the needs of recovered heat during the year were calculated, set a reserve and recommendations for its redistribution between the two beneficial effects: heat and cold, in accordance with the technological process of agricultural production were made. It is shown that the trigeneration system is capable of providing high energy efficiency of small autonomous power plant in the agricultural sector.
