Phase Change Material Cooling System

The phase transition may also be between non classical states of matter such as the conformity of crystals where the material goes.

Phase change material cooling system.

This cooling mattress pad is made with a phase change material that changes color as it absorbs heat so you can see it working and comes wrapped in a temperature regulating fabric that keeps the. The system was designed to reduce cooling load of a building and therefore the energy consumption of the hvac systems. The aim was to determine the effectiveness of the cooling system and to identify the optimal pcm beeswax or rubitherm rt 44 hc for a temperature range of 25 55 c. Generally the transition will be from one of the first two fundamental states of matter solid and liquid to the other.

During the night the cold air from outside is blown through the storage system which charges the system with cold. 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. The hybrid system that integrates active cooling into phase change materials pcms expanded graphite eg shows great prospects for power battery thermal management. As proposed in this work novel thermal management system tms can be achieved by overcoming the disadvantages of the traditional techniques.

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. One of them is passive cooling with phase change material pcms. Indeed the cells of the battery system are surrounded by this material and.

A phase change material pcm is a substance which releases absorbs sufficient energy at phase transition to provide useful heat cooling.
