Abstract:

The efficiency of utilization of cogeneration gas engine module exhaust heat into the cold by the absorption Li-Br chiller was analyzed. The presence of significant heat losses caused by contradictory conditions of joint performance of absorption Li-Br chiller and cogenerative gas engine module on the temperature of return heat fluid (heating water) at the outlet of absorption Li-Br chiller and its temperature at the inlet of cooling system of cogenerative gas engine was revealed. The two-stage chillers with absorption Li-Br chiller as a high-temperature stage and adsorption chiller or refrigerant ejector chiller as a low-temperature stage of heat utilization (according to the temperature of heating water) was considered. The application of an adsorption chiller to transform the heat of return heating water after the absorption Li-Br chiller was proposed. The possibility of applying a refrigerant ejector chiller to transform a low potential heat of return heating water after the absorption Li-Br chiller is considered. A two-stage transformation of the heat by refrigerant ejector chiller as the first stage and absorption chiller as the second stage was proposed.
