The invention provides combined heat and power, combined cooling and power, and combined heating and power-cooling and power systems, and belongs to the technical field of combined heating, power and cooling and heat pumps. The power machine supplies steam in stages, the primary heat medium flows through the first heater, the second heater and the third heater to absorb heat, and then flows through the generator, the second generator, the secondary heat exchanger and the evaporator to release heat , the absorber, the second absorber, the condenser and the secondary heat exchanger respectively supply heat to the secondary heat medium, forming a power machine, a first heater, a second heater, a third heater, a generator, a second generator, absorber, second absorber, condenser, evaporator, solution pump, second solution pump, throttling valve, solution heat exchanger, second solution heat exchanger, circulation pump and secondary heat exchanger Combining heat and power system; increase or decrease components and adjust the process to form a combined cooling and power system or a combined heating and power-cooling and power system.
Description
[0001] Technical field: [0002] The invention belongs to the technical field of cogeneration of heat, electricity and cooling and heat pump. [0003] Background technique: [0004] In the combined heat and power / cooling and power system that uses the sensible heat of thermal fluid as the heat load delivery method, a hierarchical heating system is required. Taking the large-scale combined heat and power system for heating in winter as an example, the heating temperature of the primary heating pipe network is high, and there is a large heating temperature difference between the primary heat medium and the secondary heat medium. For example, the supply and return of the primary pipe network The water temperature is 135°C / 65°C, the supply and return water temperature of the secondary pipe network is 75°C / 60°C, and the average temperature difference between the two exceeds 32.5°C. From the perspective of rational utilization of heat energy, the existence of a large temperature dif...
