OFF GRID BATTERYLESSSOLAR REFRIGERATED EVAPORATIVELY COOLED (SREC) STRUCTURE FOR STORAGE OF PERISHABLES
Description

This technology has been developed for on-farm cold storage of perishable fruits and vegetables. The solar refrigerated evaporatively cooled structure does not require grid (uninterrupted power supply) or batteries for its operation and maintains low temperatures by solar energy. This technology uses a combination of solar refrigeration and evaporatively cooled system and can achieve daytime temperatures as low as ~5-10 °C and nighttime temperatures below 14°C, when the daily ambient maximum temperature reaches even approximately 45°C. The major innovations in this technology are mesh fabric structure, “wetted” fabric for evaporative cooling, split refrigeration evaporator coil for cooling water and air, a “water battery” for nighttime cooling, a sunlight sensing for intelligent remote control (using IoT) of refrigeration system demand based on amount of sunlight present, a secure power supply inverter and a robust refrigeration unit. The energy and environment data can be accessed and remotely programmed to change refrigeration demand with sunlight intensity threshold levels from anywhere in the world.
Useful in rural areas where uninterrupted supply of electricity is not available. Two SREC structures have been installed and are in use in villages Picholiya, Ajmner, Rajasthan and Chamrara, Panipat, Haryana.

Salient Feature

It is an Off-grid and batteryless on-farm cold storer of 2-tonne capacity for fruits and vegetables. Performs as combination of solar refrigeration and evaporative cooling during daytime.
Having a cooling chamber wherein the walls are made of fabric over iron mesh, A split evaporator coil system is present for shunt cooling to a thermal reservoir, A cold-water reservoir “water battery” present to provide low-cost thermal storage for night time cooling below 14oC.
Also, sunlight sensing and remote control (using IoT) system is present for intelligent control of refrigeration system demand based on amount of sunlight. Secure power supply (no grid connection and no batteries) inverter and a robust refrigeration system is present.

PHASE CHANGE MATERIAL (PCM) BASED HYBRID SOLAR DRYER FOR HERBS AND SPICES
Technology Brief

It consists of a microcontroller-based system to regulate the drying rate to help continuous and uniform drying resulting in better product. Use of phase change material as thermal energy storage will provide continuous and uniform drying of herbs and spices for prolonged hours even after sunset resulting in better quality product.
This system avoids taking out material at frequent intervals for recording of weight thus helps in maintaining good quality product due to continuous drying.
PCM (Paraffin wax) helps in maintaining the temperature of the drying chamber for some time even after sunset. It is basically a zero energy dryer and does not require any conventional energy making it very useful for people in rural areas where there is no electricity or its supply is erratic.

Salient Feature

It provides controlled environment for drying of herbs at low temperature in order to preserve the flavour and colour. In hybrid dryer both thermal and photovoltaic energy of the sun is used to operate the dryer. The developed solar dryer provides a promising alternative for continuous drying of herbs even after sunshine hours with real time data acquisition system and also found to be superior in retaining quality.
