Abstract
The article deals with the monoblocked trigeneration experimental plant for power supply of autonomic objects. The power plant consists of power unit in the form of a diesel generator, geothermal heat pumps as sources of heat and cold supply, heat recovery boiler of exhaust heat. The heat pump compressors are driven from the shaft of the diesel engine through a V-belt transmission. On the proposed installation, the energy supply of autonomic consumers can be organized in monogeneric, simple and complex cogeneration and trigeneration modes. The article also demonstrates the results of experimental study of power plant characteristics, confirming its performance in complex cogeneration mode. The values of the energy conversion factor, obtained during testing of heat pumps in the composition of trigeneration plants, show the energy efficiency of their work for the heating mode. The author experimentally identifies the components of the energy balance, and then the composition of the exhaust gases at different levels of the load.
