Improvement of the quality of tractors and mobile systems with the aim of increasing competitiveness and preserving soil and environment (MESTD - 31046)

Keywords: heat pump; manure; coefficient of heating; heat energy
The potential of manure for getting some form of energy is most often associated with the production of biogas. Set the heat exchanger in the area for composting gives us the ability to 'collect' the heat released in the process of decomposition of organic matter. In aerobic fermentation of one mole of glucose is released in 2800 kJ, while in anaerobic 405 kJ. Cooling the manure, while reducing the loss of its nutritional value, receives a certain amount of heat. As a model of heat pump We used two box-freezer of volume 410 liters each. Heat pump heating coefficient represents the ratio between the amount of heat produced by heat pump and invested work for its operation. The maximum value of the coefficient of performance is realized at temperature of heat source t i = 35 ° C and temperature of heat sink t p = 40 ° C: ε G = 6.6, while the minimum was ε G = 2.5 at ti = 15 ° C and tp = 50 ° C. Hot water in storage tank can be used, depending on the needs as an independent source of heat or with additional heating for heating facilities like objects for fattening chickens, farrowing pens, sanitary facilities, etc.
