    A Heating, Ventilation, and Air Conditioning (HVAC) system is often utilized in passenger vehicles to enhance the comfort of both the driver and the passengers. The reliability of an HVAC system refers to the probability that a component within the system will fulfil its intended function during a specified timeframe while operating according to the predefined operational and environmental conditions. Conducting a reliability analysis for the HVAC system of a passenger vehicle is crucial to ensure safety, comfort, cost-effectiveness, and a positive standing. A methodology for analyzing the reliability analysis of a HVAC system using field failure data were developed to identify the critical failure modes, components, and subsystems. A detailed Pareto analysis was applied at subsystem and failure mode levels in order to prioritize them accordingly to their failure frequency. The analysis showed that the A/C evaporator and blower front sides were observed to be the most critical subsystems, contributing to approximately 50% of all failures. Furthermore, the leakages at the joints and vibrations are the primary failure modes of the HVAC system. The Weibull++ software package (version 2021) was used to estimate the best-fit probability distributions for each subsystem and system reliability modelling using a Reliability Block Diagram. The results show that the exponential distribution fits well for several subsystem’s Time-To-Failure (TTF) data and show that the failures were random and due to external reasons.

    Preservation of perishable food produce is a major concern in the cold chain supply system. Development of an energy-efficient on-farm cold storage facility, hence, becomes essential. Integration of thermal storage into a vapor compression refrigeration (VCR)-driven cold room is a promising technology that can reduce power consumption and act as a thermal backup. However, designing a latent heat energy storage heat exchanger encounters challenges, such as low thermal conductivity of phase change materials (PCMs) and poor heat exchanger efficiencies, leading to ineffective charging–discharging cycles. The current study investigates the effect of the integration of a Phase Change Material (PCM) in terms of the selection of the PCM, the optimal positioning of the PCM heat exchanger, and the selection of heat exchanger encapsulation material. Numerical analysis was undertaken using 3D Experience software (version: 2024x.D31.R426rel.202403212040) by creating a 3D model of a 3.4 m3 micro-cold storage unit to understand the inner temperature distribution profile. Further, the experimental setup was developed, and tests were conducted, during which the energy consumption of 1.1 kWh was recorded for the total compressor run time of 1 h. Results indicated that an improved cooling effect was achieved by positioning the PCM trays on the wall opposite the evaporator. It is seen that a temperature difference in the range of 5 to 7 °C exists between the phase change temperature of PCM and the optimal storage temperature depending on the encapsulation material. Hence, PCM selection for thermal storage applications would have an important bearing on the material and configuration of the PCM encapsulation.

    Carriage of fresh fruits and vegetables under ordinary conditions of refrigeration lead toaccelerated deterioration due to accumulation of undesirable gases. Shelf lifeof fresh produce can beenhanced by storage at optimum temperature and humidity and by admitting fresh air into the system. A prototype cold store is developed to maintain desirable temperature and humidity. In addition, a mixing arrangement is designed which controls the ratio of the return and outside air. Through the experiments, it was found the percentage weight loss of oranges kept in the cold store at 5 °C and 95% humidity was found to be about 10.14%. A storage life of about88 days (∼ 3 months or 13 weeks) was obtained. This represents a 30% extension in shelf life in relation to oranges stored in a refrigerator. After the said storage period, the fruit was found edible and marketable.

    Upon remote monitoring of more than 25 off grid battery supported solar mini grids in India for over 2 years, it has been observed that battery output of all such systems reduced by 50% - 60% in 3 years of operation and further reduced to 30%-40% in 5 years of operation with overall output of solar PV also reducing considerably in this period. The batteries in solar PV systems are seen to give less than half the design life prescribed by manufacturers and BIS standards. This occurs due to "hard sulphation" which can be reduced by a proper discharging process & removed by special charge treatment.Lab scale experiments to provide the equalization charge to solar batteries and their on ground applications prove that batteries of solar PV plants can provide more than 80% of their rated capacity for 8 to 10 years or more, provided charge and discharge process and periodic freshening is done.

    A small wind turbine blade was designed and optimized in this research paper. The blade plays an important role, because it is the most important part of the energy absorption system. Consequently, the blade has to be designed carefully to enable to absorb energy with its greatest efficiency. The main objective of this paper is to optimized blade number and selection of tip speed ratio corresponding to the solidity. The power performance of small horizontal axis wind turbines was simulated in detail using blade element momentum methods (BEM). In this paper for wind blade design various factors such as tip loss, hub loss, drag coefficient, and wake were considered. The design process includes the selection of the wind turbine type and the determination of the blade airfoil, twist angle distribution along the radius, and chord length distribution along the radius. A parametric study that will determine if the optimized values of blade twist angle and chord length create the most efficient blade geometry. The 3-bladed, 5-bladed and 7-bladed rotor achieved maximum values of Cp 0.46, 0.5 and 0.48 at the tip speed ratio 7, 5 and 4 respectively. It was observed that using BEM theory, maximum Cp varied with strongly solidity and weakly with the blade number. The studies showed that the power coefficient increases upto blade number B = 5, while the blade number if increased above 5 then the power coefficient decreases at operating pitch angle equal to 3°. Highest Cp would have solidity between 4% to 6% for number of blade 3 and design point tip speed ratio of about "7". Highest Cp would have solidity ranging from 5% to 10% for number of blade 5 and 7 and design point tip speed ratio of about 5 and 4 respectively.

  • Design and optimization of isolated wind-battery systems incorporating multiple wind generators

    Systems consisting of multiple wind-generators along with a single battery bank are a sustainable alternative for supplying the energy requirements of remote locations not connected to the national grid. In this paper, a methodology for sizing and optimizing wind-battery systems employing multiple wind turbines is proposed. Uncertainty in wind resource availability is taken into account by formulating the problem as a chance constraint. Based on a time step simulation, subject to different technical and physical design constraints, the entire solution space in terms of the system design variables viz., generator rating, rotor diameter and battery bank size for a specified number of wind turbines and reliability requirement is generated. The domain containing all feasible solutions is the design space and it is a function of system reliability requirement and the number of wind turbines. From the design space of multiple wind turbine-battery systems, it is shown that with an increase in the number of wind generators, the rotor diameter, generator rating of individual turbines as well as battery bank size can be minimized along with a benefit in the overall cost of energy (US$/kWh). Additionally, by increasing the number of wind generators it is possible to comply with a stringent power supply reliability target which would otherwise not be possible. The strength of the proposed methodology lies in the visualization of alternative solutions and identification of the minimum and the maximum limits of various system design variables.
