This study presents the performance of a novel solar-powered incubator which uses water as thermal mass. Energy absorbed by the water is transferred to the incubator chamber by a fan powered with a 12 V battery. To enable adequate control of chamber temperature and humidity, a ProNem Mini sensor and controller (ESM-3723) were incorporated into the design. The thermal mass was sized adequately to supply energy for night operations as well as periods of inclement weather. The incubator was tested with and without load. Field measurements were obtained using UT330A USB datalogger. Tests under no

Pollution is increasing very effectively in the world. It must be reduced the present pollution levels by the deadline even though the long-term solution to the pollution problem is to identify and reduce pollution sources. The use of air purifiers is the most effective method of reducing pollution. Regular interior air purifiers, however, are little, low-power gadgets that lack the necessary filtering capacity for outdoor environments. Additionally, there is a problem with outdoor machines' power supplies. Therefore, it has created a solar outdoor air purifier that is energy independent and b

Abstract:
In regions with hot and mixed climates, the principal energy users in buildings are the systems that provide cooling and air-conditioning. Buildings consume more energy as a result of their reliance on traditional electrically powered systems. Solar energy has emerged as an important alternative for many uses, including cooling and air-conditioning. In this paper, to simulate a solar-assisted single-stage LiBr-H2O absorption air conditioner system, a mathematical model is presented. The model may simulate either the static or the quasi-static state of the system. The model is constructed using

A solar-based renewable energy source is also used along with the traditional charging mechanism to make a hybrid system.
