摘要： A method provides for waste heat power generation or heat recovery and for a driving power with an absorption process using low grade heat sources. An apparatus also provides for such waste heat recovery in absorption process and to the used vapor-salt working fluid. A low temperature heat source is used as a heating working medium to heat in a regenerator by heat exchange the absorption liquid working fluid from the absorber and consisting of a salt absorbent and ammonia or carbon dioxide as an absorbed agent to form the absorbent and the superheated high pressure absorbed agent. The superheated and vaporized absorbed agent enters into a turbine to provide energy and generate power via turbine expansion step. After heat release, the resultant low pressure absorbed agent is discharged from the turbine and returns to the absorption step and contacts with the absorbent from the regeneration step to form the absorption liquid which can enter into the next thermodynamic cycle process.

摘要： A method of controlling a hydronic system is provided. The hydronic system includes a plurality of fluid heat exchange units for feeding a load, and a bypass valve for bypassing the load. The method includes operating at least a first and a second fluid heat exchange unit in the hydronic system to heat or cool a fluid. An output fluid flow of each of the operating fluid heat exchange units is monitored. The monitored output fluid flow of each fluid heat exchange unit is compared to a predetermined fluid flow setpoint. The output fluid flow of each of the operating fluid heat exchange units is adjusted towards the predetermined fluid flow setpoint if the monitored output flow is different from the predetermined fluid flow setpoint by at least a predetermined margin. A combined output fluid flow of the operating fluid heat exchange units is also monitored. The bypass valve is at least partially opened if the combined output fluid flow is below a predetermined minimum combined output fluid flow. A previously idle fluid heat exchange unit is operated if the combined output fluid flow is greater than a predetermined maximum combined output fluid flow for the number of operating fluid heat exchange units.
