“…CCHP systems working with different prime movers such as steam turbines, MGTs and reciprocating internal combustion engines are also studied in [55][56][57][58][59][60][61]. References [58] and [59] investigated using hydrogen and biomass as fuel and compared the environmental benefits of these fuels with respect to fossil fuels. A photovoltaic (PV)-CCHP system was proposed by [62] to meet the load demands of a consumer.…”

“…Also, the highest exergy efficiency of their system is 50%. Wang et al [10] investigated a CCHP from the perspective of energy and carbon dioxide emissions. The prime mover of their proposed system was a diesel engine, and they also investigated the effect of using two types of fuel, hydrogen, and diesel, on the system's performance.…”

Using cogeneration systems is a great way to tackle fossil fuel consumption problems. This paper introduces a Combined Cooling Heating Power (CCHP) system to recover the waste heat of an RK215 heavy diesel engine as a prime mover. Therefore the CCHP system consists of Internal Combustion Engine (RK215), a heat storage tank, and an absorption chiller. Also, the system has been studied in four modes: CCHP, CHP, CCP, and single generation. The waste heat ratio has changed due to a y factor, and the effect of this different parameter, such as the start of fuel injection and exhaust gas heat, on the system's efficiency by considering first and second laws of thermodynamic in different operating modes has been investigated. The system's highest energy and exergy efficiency in CCHP mode is equal to 50.46 and 30.8%, respectively. According to the result, as the CCHPs cooling load to the absorption chiller increases, the performance also rises. Also, the system's carbon dioxide emissions reduction has been studied. The results showed that using different modes for waste heat recovery can reduce carbon dioxide by up to 30% approximately for different modes. Also, the fuel energy saving ratio (FESR) has been investigated, and the results showed that systems in CCHP, CHP, and CCP modes could have FESR approximately equal to 21%.

“…The parts of the investigated trigeneration system have crucial relationships with each and every one by reason of the endogenous‐exergy destruction of the components, which were less than the exogenous‐exergy destruction as conclusions indicated. Wang et al 17 examined an energy conversion system (trigeneration) with a 6.5 kWe hydrogen‐fueled engine, which was losing heat, realized from combustion products and engine cooling processes, employed for household purposes (cooling/hot water). Their work demonstrates that hydrogen is an extremely impressive fuel that gives allowance for performing similar or much better performance to traditional diesel fuel from the point of view of thermodynamic law outcomes and carbon neutrality.…”

The objective of the research is to discuss the issues, opportunities, and benefits of a combined heat and power system, including a micro gas turbine engine (M-CHP) operated by natural gas, with an estimated sale price of $245 000 that produces 225 kW-net of electrical power and a 209.8 kW-net thermal power output in the industrial zone via thermodynamic indicators that help to measure the cost rate, the environmental/ecological effects, and sustainable growth. The ratio of useful energy output (electrical and heating) to the fuel energy for the M-CHP is computed to be 70.2%. In addition, other indicators constituting the practical implications of the study, with a capacity to cause a positive change in fuel consumption and the amount of pollutants (electrical to heating ratio, efficiencies of exergy and improved exergy, fuel exergy depletion and productivity lacking ratios, improvement potential, cost rates and sustainability indexes) are detailed. The novelty of this work is the capability to serve as guide for similar systems with a detailed approach in performance and environmental assessment by prioritizing efficiency and fuel consumption. This investigation intends to establish a design for the opportunities and benefits that a thermodynamic approach provides to M-CHP systems.
