Phase Change Material Cooling System
The system was designed to reduce cooling load of a building and therefore the energy consumption of the hvac systems.
Phase change material cooling system. The most important component is the latent heat thermal energy storage system including phase change material package bed and the air duct among the pcm capsules. During the night the cold air from outside is blown through the storage system which charges the system with cold. Act is developing a cool storage system that uses phase change material pcm and thermosyphons to increase the cooling capacity during the daytime by melting the pcm thermal storage with venting most thermal storage systems are designed to store heat by melting a phase change material pcm and can operate over a very large number of cycles. Pcms introduce a less complex level of the battery design.
But because of the heavy weight the system need to be optimized with a balance of the cooling capacity contributed by the active and passive cooling. The hybrid system that integrates active cooling into phase change materials pcms expanded graphite eg shows great prospects for power battery thermal management. The phase transition may also be between non classical states of matter such as the conformity of crystals where the material goes. One of them is passive cooling with phase change material pcms.
An innovative system consisting of a ventilated facade with macroencapsulated phase change material in its air chamber was experimentally and numerically studied by de gracia et al. A phase change material pcm is a substance which releases absorbs sufficient energy at phase transition to provide useful heat cooling. Generally the transition will be from one of the first two fundamental states of matter solid and liquid to the other. In this study passive cooling systems were constructed with a heat pipe and phase change material pcm and their performances were investigated with battery simulators.
Indeed the cells of the battery system are surrounded by this material and.
