Traditional cooling systems for buildings often consume significant energy and may not efficiently manage temperature variations throughout the day. There is a need for a more efficient and cost-effective method to reduce thermal load and stabilize indoor temperatures.
This invention relates to a cooling method for building spaces using a heat exchanger that incorporates encapsulated phase change material (PCM). This heat exchanger reduces the thermal load and stabilizes the mean air temperature of the building space. The system involves a container filled with PCM and a tube for circulating a working fluid, which transfers heat to and from the PCM, enabling effective temperature regulation.
- Encapsulated PCM within a container, with a tube passing through the PCM, with an inlet and outlet for circulating a working fluid
- Efficient thermal load reduction and temperature stabilization
- Uses water's high heat capacity for better cooling compared to air-based systems
- Cost-effective and energy-efficient, with reduced need for continuous operation
- Can be installed as a false ceiling for radiant cooling
A cubical test chamber with dimensions of 710 mm per side and 57 mm wall thickness, featuring a small window, was used to test the system. The chamber included T-Type thermocouples for temperature measurement and a PCM layer of 18.4 mm thickness.
The technology has been developed and tested in a controlled environment using a cubical test chamber. Performance studies have shown promising results in reducing and stabilizing air temperatures.
