Ice Thermal Energy Storage TES has the benefit of universal accessibility, low cost and transportation ability through other system elements. But low temperature chillers are required by an ice TES system for ac application and therefore water chillers have to be replaced and have more power. If we can offer Designers an ice that freezes and melts over or below 032 these new products will open new horizons for environmentally friendly and economical systems for both New and Retrofit type procedure cooling heating load shifting software. Phase Change Material PCM Eutectic solutions are combinations of two or more chemicals that, when mixed in a specific ratio, have a freezing melting point under or above water freezing temperatures of and they supply a renewable energy storage facility involving 114 and +164 .
Eutectics are Applications that are well known and actually date back to the 18th century their wide spread use was restricted and the separation and the life expectancy of these mixtures were unpredictable. The disadvantages of a Conventional HVAC chiller and ice water ice storage system may be overcome by utilizing the latent heat capacity of various Eutectic mixtures without needing minus circulation temperatures. Phase Change Material PCM renewable energy storage not only allows the designer to use existing chiller technology but also enables charging by Way of free cooling, i.e. without running the chillers although the term Eutectic is broadly used to refer to the materials were interested in, a better description would be Phase Change Materials PCMs. Very few of those PCM solutions that are documented are many must be modified to get a material acceptable for long term usage and Eutectics.
PCMs can be grouped into two groups Organic Compounds and Salt based Products. The basic requirement for a modified Eutectic pc fans Solution can be classified in three categories, namely secure alternative no separation or degrading, minimal super cooling heating and ultimately close freezing and melting temperatures. There are three Fundamental additives utilized to modify salt. These 3 elements are Nucleating Agent which reduces cooling that is super and promotes Crystal formation and the additive that is second is Freeze Depressant to attain a phase change temperature and Gelling Thickening Agent so as to overcome degrading and separation issues.
Once the above Components have been carefully implemented, a decent Eutectic PCM Solution could be produced in the physical and thermodynamic point of views and commercially available alternatives provide a range of 114 and +164 .However, majority of PCM options for refrigeration and HVAC systems are corrosive to line parts and pipe and suitable encapsulation techniques must be implemented to overcome this problem. The PCM options are encapsulated in plastic or metallic shell encapsulation techniques like tube container or rather ball concepts are developed.
