Heat and cold storage using phase change materials in domestic refrigeration systems: The state-of-the-art review

The cold storage is a big room or commercial building used to store perishable items like vegetables, fruits, fish, milk products, meat, etc. under controlled conditions where temperature, humidity, etc. are controlled for a longer duration. Different types of cold storages are available and selection of cold storage is based on the application. In recent years, solar hybrid cold storage systems are getting popular due to lower operating cost and reduced greenhouse gas emissions. Also, thermal energy storage systems with phase change materials are being used in cold storage systems. The new technologies are developed to reduce the energy consumption of cold storage systems. The quality of the perishable items stored in the cold storage may be retained by applying nano coating on the fruits. This chapter reviews cold storage systems, elements of cold storage, design of cold storage, application of phase change and nano particles in cold storage system.

Nanocomposite Pcm

A new organic phase change materials (PCM) for cool storage was developed for use in cold storage air-conditioning. The thermal properties of the new organic PCM were measured with a differential scanning calorimeter (DSC). To improve the thermal conductivity of the new organic PCM, the further research of using nanocomposite technology to the organic PCM SSW-4 was made. The effects of nanoparticles concentration on dispersion, ultrasonic time and consistence of dispersant in the best ultrasonic time on the dispersion were investigated by experiment. The results showed that the thermal conductivity of the nanocomposite PCM TiO2 /SSW-4 increased by approximately 16.27% compared to that of the organic PCM SSW-4. The best dispersion condition of preparation for TiO2 /SSW-4 was confirmed.
