Summary
Growing energy demand from economic output and improved standards of living will likely put added pressure on energy supplies. Storing energy allows researchers to balance the supply and demand of energy. There are three types of thermal storage energy systems including sensible heat storage, latent heat storage and thermo-chemical storage. Ice storage system is a latent cold storage which uses ice for cold energy storage. Cold energy storage helps cooling capacity overnight for later usage during peak hours. The most common form of cold storage air conditioning technology is the ice-on-coil energy storage. In this study, the solidification process in an ice-on-coil cold storage system is numerically investigated. The porosity-enthalpy method is used to simulate the solidification process. Once carefully validated, the model is extended to quantify the effects of different geometrical parameters including helix pitch of coil, coil diameter and length on charging process.
