A review paper on Solar Dryer
The unpredictable rise and frequent scarcity of fossil fuel accelerated the continuous search for an alternative power source. Solar is one of the renewable and sustainable sources of power that attracted a large community of researchers from all over the world. This is largely due to its abundant in both direct and indirect form. As such the development of efficient and inexpensive equipment f...
متن کاملThermal Analysis of Photovoltaic Integrated Greenhouse Solar Dryer
Abstract—Present study focused on the utilization of solar energy by the help of photovoltaic greenhouse solar dryer under forced mode. A single slope photovoltaic greenhouse solar dryer has been proposed and thermal modelling has been developed. Various parameters have been calculated by thermal modelling such as greenhouse room temperature, cell temperature, crop temperature and air temperatu...
متن کاملModeling and experimental studies on a domestic solar dryer
A domestic solar dryer with transparent external surfaces was designed, built and tested. Thin-layer drying models that describe the drying phenomena in a unified way, regardless of the controlling mechanism; have been used to estimate the drying period for several products. Temperature of the drying medium is one of the factors that affect the drying rate constant of the exponential model. Thi...
متن کاملReview Paper: COVID-19 and Orthodontic Emergencies: A Narrative Review
Abstract COVID-19 pandemic has faced orthodontists with challenges. The number of unnecessary orthodontics visits should be decreased to stop the spread of this virus. However, if the patients undergoing orthodontic treatments are not followed for more than two months emergencies can occur. Hopefully these emergencies can mostly be handled at home if the orthodontist guides the patient c...
متن کاملA Wireless Greenhouse Monitoring System based on Solar Energy
To resolve the problems of complicated cabling and costly wired network in the current system, we designed a wireless greenhouse monitoring system based on ZigBee and GSM technology. The system consists of two parts: a wireless sensor network and remote control terminal. According to parameter distribution in the monitoring regional, a wireless transmission network was formed, all of the nodes ...
