Refrigeration systems have the priority in design for residential and industrial applications. The chapter includes five major refrigeration systems: vaporcompression refrigeration; ammonia-water absorption refrigeration; gas refrigeration where standard air is the most popular refrigerant; multi-pressure refrigeration including multistage, cascade, and multipurpose refrigeration system; and heat pump systems. Energy and exergy analysis has been presented for most of the systems. The energetic and the exergetic COP for each system are presented. Renewable energy sources are also discussed including geothermal, solar, and wind energy, a with combination with refrigeration systems in different industrial and residential applications. The overall efficiency of the renewable systems is achieved to be more than 50% providing promising solutions for energy use and having a low environmental impact.

Due to the necessity of achieving the energy systems with improved efficiency, combined power plants are developing in recent decades. Moreover, employing renewable energy sources in the power generation and heating/cooling purposes is an attractive idea to obtain more environmentally benign energy systems. In the current study, a combined cooling and power (CCP) plant is analyzed based on exergy and economic concepts. Afterward, by adding lithium‐bromide refrigeration cycle and parabolic solar collectors, the plant is investigated. The exergy efficiency, carbon dioxide emission, and cost of generated electricity are evaluated on the basis of SPECO model. The results of the study show that thermal and exergy efficiencies of the CCP plant with the solar collector depend on various parameters and can be affected significantly. The efficiency of the plant after applying lithium‐bromide refrigeration cycle and the solar collector increased from 50.33 to 51.73%, while the exergy efficiency enhanced from 47.48 to 48.22%. In addition, it was concluded that adding the collector and absorption chiller leads to 1.5% reduction in environmental pollutants.

Mohammadi et al applied the exergy analysis model to analyze the wind energy coupled with compressed air energy storage systems and the effect of key parameters on this system. Yang et al conducted both conventional and advanced exergy analyses on a large‐scale ultra‐supercritical coal‐fired power plant and showed the dependencies of the overall exergetic efficiency on a number of key design parameters.…”

Summary In a large‐scale chemical plant, it is important to evaluate the energy efficiency (EE) of production to improve the production process and make production decisions. Essentially, finding the relationship model is the foundation of EE evaluation. Given the requirements of universality and practicability, the data‐driven model is widely used to describe the variable relationships. However, the variables stored in the data bank may be redundant, and some variables contain disturbances in the large‐scale chemical process, increasing the complexity of the model establishment. In this paper, a new EE factor extraction and EE evaluation method based on principal component analysis (PCA) (EEPCA) is proposed to enhance the accuracy of the EE values. By three stages (noise term estimation, model establishment, and model variable selection) in EEPCA, the accurate relationship models of utilized energy mediums and chemical products are established. On the basis of the built models, the EE of the chemical processes is evaluated and inferred. The effectiveness and practicality of the proposed method are demonstrated via a simulated process and a practical ethylene production.
