Embodiment Construction
[0018] figure 1 It is the humid air thermodynamic cycle combined cooling and power generation system proposed by the present invention, refer to below figure 1 Explain how the system works:
[0019] In the humid air turbine circulation subsystem 1, the humid air is first compressed by the compressor 11, and then enters the saturator 12 for humidification after being heated and pressurized. Enter the gas turbine 14 to expand and do work, and at the same time drive the generator 15 to generate electricity and the compressor 11 to work, and the humid air after the turbine enters the exhaust fan 16.
[0020] In the absorption dehumidification subsystem 2, the hot air from the exhaust fan 16 in the humid air turbine circulation subsystem 1 enters the generator 21 to heat the dilute solution, and the cooled humid air enters the absorber 24 through the dehumidification fan 26 for dehumidification; The solution forms an internal circulation in the absorption dehumidification subsyst...

The invention discloses a moist air thermal cycle cold electricity cogeneration system and a working method thereof, and belongs to the technical field of industrial energy conservation. The system comprises three subsystems of a moist air turbine cycle subsystem, an absorption dehumidification subsystem and an evaporative cooling subsystem, and is characterized in that the system is of an open moist air thermal cycle structure, is driven by solar energy, and does not consume fossil energy such as coal and natural gas while meeting the requirements of a user for the cooling load and the electric load, especially based on an absorption dehumidification structure in the moist air thermal cycle, the adaptability of evaporative cooling refrigeration to the environmental humidity can be greatlyimproved, and meanwhile cascade utilization of energy is achieved. Thus, the energy utilization efficiency is improved, emission of carbides and harmful gases is reduced, and the system has good economic benefits and social benefits.
Description
technical field [0001] The invention designs a wet air thermodynamic cycle cogeneration system and a working method thereof, which belong to the technical field of industrial energy saving. Background technique [0002] Distributed Energy System (Distributed Energy System) is already a mature energy comprehensive utilization technology in many countries and regions. It is close to users, cascade utilization, high efficiency of primary energy utilization, environment-friendly, safe and reliable energy supply, etc. It has received wide attention and favor from governments and business circles of various countries. There are many forms of distributed energy systems, and the combined cooling and power supply of regional or building groups or independent large and medium-sized buildings is one of the very important ways. Affected by my country's energy structure, most of my country's cogeneration systems currently use coal as the main fuel. Even though there is a tendency to use...
