Cogeneration system

Abstract

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. The absorber, the generator, the second generator, the condenser, the second condenser, the solution pump, the second solution pump, the solution heat exchanger and the second solution heat exchanger constitute an absorption solution circulation process; The passage and the exhaust steam passage communicate with the outside, the power machine provides low-temperature heat load to the second generator through the exhaust steam passage, the power machine provides steam to the absorber through the first steam passage, the generator has a high-temperature heat medium passage, and the absorber and condenser have The heated medium channel and the second condenser have cooling medium channels respectively connected to the outside, the second generator has condensate channels connected to the outside, and the condenser and the second condenser have condensate channels connected to the outside respectively, forming a thermodynamic linkage for the 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...
