STUDY ON COOL STORAGE-SYSTEM USING CFC-11 (CCL3F) CLATHRATE

Experiments were performed to investigate the possibility of a direct- contact-charged cool storage system and indirect-contact-charged cool storage system using clathrate for use in air conditioning of building s, by storing energy of night excess power at a cool storage density a nd taking it out as cool heat when energy become necessary in the dayt ime. Using CFC-11 (CCl3F) clathrate, the following conclusions were ob tained. 1. Cool storage system using clathrate is a more suitable heat storage system than water and ice. 2. Addition of 0.01 similar to 0.1 wt% additive allowed ideal clathrate formation and decomposition up t o 40 wt% of clathrate concentration. 3. Addition of ethyleneglycol all owed clathrate formation and decomposition temperature decreases, resu lting in the aquisition of more cooled chilled water.
