Solar powered peltier cooling storage for vaccines in rural areas

Abstract

The research presented in this paper proposes a new design of a vaccine cooling and storage unit that can keep vaccines in the cold chain (2°C to 8°C). This design was done to facilitate effective completion of the African vaccination week. The cooling and storage unit was designed to be compact, portable, well isolated and to make use of a PV solar energy system as a source of electricity. The cooling unit makes use of a Liquid to Air thermoelectric cooling module connected to some tubing and a liquid pump to cool the inside of the cooling unit. The design process also included designing a control system that controls the temperature inside the cooling holder and a monitoring system to monitor the battery voltage and capacity. The system also has a user interface that displays the temperatures inside and outside of the cooling holder, as well as the battery voltage and capacity. The cooling system successfully developed was able to keep vaccines in the cold chain for up to three days, the system could control the temperature of the vaccines with an accuracy of 1°C and was small and portable, but still had enough room to house up to 250 vaccines.

Vaccine cold chain management and cold storage technology to address the challenges of vaccination programs

“…This technology generally integrates solar energy power generation systems ( Alfariani and Pratama, 2018 ). With this concept, Buitendach, Jiya, and Gouws succeeded in creating a portable storage unit that tends to last up to 72 h (3 days) with a temperature control accuracy of 1 °C and a capacity of up to 250 vials ( Buitendach et al, 2019 ). Al-Madhhachi and Al-Najideen (2020), with COMSOL Multiphysics technology, also succeeded in developing a storage unit by utilizing a lower solar panel power of 70 watts ( Al-Madhhachi and Al-Najideen, 2021 ).…”

Fuzzy Logic Control Solar-Powered Portable Cooling Box

“…In this research, fuzzy logic control was used in a specific prototype project to obtain specific results. Vaccine storage in rural areas with Peltier cooling powered by solar that can keep vaccines cold chain (2 °C to 8 °C) [19]. But this research updated it from 2°C to 16°C so that it becomes useful for insulin too [20].…”

Personal air-conditioning system using evapolar as heat waste management

“…Hot temperatures in a space must be removed to achieve a thermal comfort zone [6]- [9]. The previous researcher found that the Peltier module can cool down temperature and develop it as a portable air conditioner [10]- [13]. It is proven to overcome waste energy consumption in portable air conditioning, Peltier module was used.…”
