Different solar thermal collectors have been used recently to meet the thermal requirements of single effect and double effect vapor absorption cooling systems, making selection of the correct method a challenge. Different attributes of each vapor absorption cooling and solar collector combination are taken into account, and a Multi-Attribute Decision-Making model is used to select the best option. The model requires variables indicating the performance of the system, which are called attributes that are organized into a hierarchical structure called a tree of attributes. The dependent attributes finally end up in the basic attributes representing the input to the model. The technology options considered are flat plate water heating collectors with forced circulation, flat plate air heating collectors with forced circulation, evacuated tube collectors, parabolic trough collectors, and collectors with compound parabolic concentrator. Two types of cooling, namely single effect and double effect, are compared. Three climatic zones with three different cooling loads, ambient temperatures and solar radiation intensity have been considered. Comparison of the solar vapor absorption technologies with vapor compression technology is made considering the major performance factors. The major attributes, namely cost and emissions produced, are compared with conventional vapor compression methods.

“…Renewable energy technologies such as solar (solar power plants), wind energy (wind turbines), thermal energy, and even ocean waves have increased the world's electricity generation [22]. Using computer intelligence, people have evaluated the economic benefits of hydro and wind power generation systems [3,23,24,47]. In Pakistan, the daily solar insolation is recorded 5 to 7 kWh/m 2 /day, which provides 18 to 25 MJ energy/day.…”

The research will discuss and explore the status and prospects of renewable energy sources (solar, wind, and biomass) in Pakistan. The future power demand, as well as the general growth in power consumption, were considered. The findings demonstrated that renewable energy sources like solar, wind, biomass, and hydro are the only remedies to tackle Pakistan's future energy challenges. Moreover, the potential energies of offshore wind, tide waves, ocean terminals, and geothermal need to be investigated and discovered. The geographical location of the region arrests 7 kWh/m 2 solar insolation daily, which can produce 25 MJ of energy. In addition, global irradiation on a horizontal surface can generate 2.4 MWh of energy per annum. Similarly, plains and mountain regions can generate 50,000 MW of electric power. Additionally, the importance of renewable energy in graduation and post-graduation programs and public awareness has been addressed. It has been concluded that due to the geographical location, solar energy is the short-term and best solution to deal with the energy crisis in Pakistan.

“…Few researchers suggested the natural ventilation or air supply system and solar chimney for improving the thermal environment in hot and humid regions [109][110][111]. Accordingly, some researchers guided the optimization modeling such as "heating and cooling" systems for better thermal comfort conditions, which helps to save energy consumption [112][113][114][115][116].…”

Railway transportation plays a significant contribution to carrying passengers in India. In which during the journey, pantry cars are involved to serves the food to all onboard passengers. The kitchen atmosphere of the pantry car gets very hot and humid during cooking which could affect occupants' thermal comfort. Therefore, the current research article describes a review of the factors affecting human thermal comfort inside the kitchen of the railway pantry car. The factors influencing of human thermal comfort inside pantry car kitchens are classified into two categories viz; environmental factors that include "air temperature, mean radiant temperature, relative humidity, air velocity" and personal or individual factors including "metabolic rate and clothing insulation". All these factors need to be considered in order to achieve the optimum level of thermal comfort inside the kitchen environment of the pantry car. With the assistance of all these factors, we can estimate the thermal comfort indices such as; SET "standard effective temperature, " PMV "predicted mean vote, " PPD "predicted the percentage of dissatisfied, " thereby recognizing the acceptable thermal sensation range for occupants' (chefs) in the pantry car kitchens during the work period. These kinds of parametric studies can cover a wide group of all pantry car chefs in evaluating thermal comfort. Furthermore, there is a need to apply all the consequences of this research to increase the chef 's thermal comfort inside the pantry car kitchen while working.
