ABSTRACT
Introduction: Non-renewable energy sources discharge destructive gases to the environment; In addition, they have restricted assets that will be depleted in the early future. In gas power generation systems, a large amount of heat is lost by exhaust gases. Consequently, using of waste heat increases power plant’s efficiency. The combined cooling, heating, and power (CCHP) is a system that can produce power, heating, and cooling from a common energy source such as natural gas, oil, or sun. In a CCHP system, waste heat drives heating and cooling devices. In this paper, the amount of noise and environmental pollution of the gas CCHP system and the Solar CCHP system have been investigated and analyzed.
methods: Gas cogeneration systems have been studied in terms of pollution and noise produced for residents. Due to the multiplicity of primary actuators, only natural gas actuators that can be implemented in residential buildings are considered here. All calculations have been done for residential buildings with EES software and after analyzing the gas cogeneration system,
Results: The results have been compared with the solar cogeneration system. The initial cost of the systems, the pollution created and the amount of noise in the various prime mover of the cogeneration systems have been examined and the cogeneration system with the solar collector has been described as the cleanest, quietest and the most expensive cogeneration system.
Conclusion: It is possible to use the cogeneration cycle in all areas and in any weather conditions, while the use of the cogeneration cycle is suitable in areas with high hours of solar radiation, which is one of the weaknesses of solar systems.
