Phase Change Material (PCM) Eutectic Solutions Used For Passive Cooling

Thermal Energy Storage (TES) may be considered as a useful tool to reduce the cooling load requirement by means of spreading day time loads over 24 hour period utilising the naturally occurring ambient temperature difference.

The night-time cooler ambient can be used to charge the latent heat capacity of various Positive Temperature Eutectic also called Phase Change Material (PCM) solutions between +4°C ( 39°F) and +117 °C (243°F) without using any refrigeration machinery by simply allowing the surrounding air to freeze these solutions. Later the stored energy by the Positive Eutectic, PCM Thermal Energy Storage can be released back to the occupied space during day-time to handle the heat gains.

This technique is generally called Passive Cooling and it may enable the charging process to take place by means of free cooling, i.e. without running the chillers and as a result becomes a very economical and environmentally friendly system. Furthermore, PCM energy storage opens new opportunities to explore heat balance for the existing and new systems, which could offer significant overall system efficiency improvements. Deschloroketamine Alternatively, the sun energy during day-time is stored and later utilised during colder night-time to heat the space for a free heating as well as storing heat in the hot water circuits.

Privatisation has created a new kind of energy market whereby the period of energy usage and the type of energy used is becoming the main criteria for price structuring rather than overall energy consumption. Hence, cooling systems must be designed to provide sufficient flexibility for load shifting and a PCM Thermal Energy Storage technique can be considered as a useful tool to achieve this aim.

Building services must be designed to provide sufficient flexibility for load shifting and energy usage control in order to achieve the most economical operation. A PCM Thermal Energy Storage technique whereby “Storing High or Low Temperature energy for later use in order to bridge the time gap between energy availability and energy use” can be considered as a useful tool to achieve this aim.

Passive Cooling PCM Thermal Energy Storage (TES) benefits can also be applied for electronic chamber, shelter, telecom shelters, remote pump and electric control cabinet cooling for remote location whereby the lack of electricity eliminated the mechanical air conditioning or alternatively mechanical cooling free applications around the World.
