[0002] In the steam power plant, although the temperature difference between the exhaust steam of the power machine and the environment is small, the heat is huge, especially in winter, and the temperature difference between the low-pressure exhaust steam discharged by the steam power plant and the environment is often difficult to use; There is a heat transfer temperature difference between gas and power cycle steam that is difficult to use effectively, resulting in low comprehensive energy utilization rate of the combined heat and power generation system, and bringing certain restrictions on the utilization of clean energy in the combined heat and power generation system

The invention provides a combined heat, power and cooling system, which belongs to the technical field of combined heat, power and cooling and heat pumps. Generator, second generator, absorber, condenser, second condenser, evaporator, throttle valve, refrigerant liquid pump, solution pump, solution heat exchanger and second solution heat exchanger constitute an absorption heat pump cycle System; the power machine provides low-temperature heat load to the generator through the exhaust steam channel and the low-temperature heat load to the evaporator through the first steam channel, the second generator has a high-temperature heat medium channel, and the absorber and the second condenser have heated medium The channel and the condenser have cooling medium channels to communicate with the outside respectively to form a combined heat and power supply system.
Description
Technical field: [0001] The invention belongs to the technical field of cogeneration of heat, electricity and cooling and absorption heat pump. Background technique: [0002] In the steam power plant, although the temperature difference between the exhaust steam of the power machine and the environment is small, the heat is huge, especially in winter, and the temperature difference between the low-pressure exhaust steam discharged by the steam power plant and the environment is often difficult to use; There is a heat transfer temperature difference between the gas and the power cycle steam that is difficult to effectively use, resulting in a low comprehensive energy utilization rate of the combined heat and power generation system, and bringing certain restrictions on the utilization of clean energy in the combined heat and power generation system. [0003] The present invention is based on the premise of efficient utilization of heat energy, takes full advantage of the temp...
