PCM-filled piping for the air conditioning of existing buildings.
Number: 0042
Author(s) : FRIEDRICH T.
Summary
A system consisting of decentralized heat storage is presented. The units work multifunctionally by being used as storage and for distributing thermal energy. The newly developed elements consist of a slim metal tube that is filled with PCM for optimal heat storage. The storage is loaded with a time delay using renewable energy. The temperature difference in the outside air is used daily or weekly for efficient storage. The temperature of the collected energy must be below the switching point of the PCM. If this constellation does not exist, the temperature is changed by using a thermoelectric heat pump based on Peltier elements. This means the required temperature is always reached.
The switching point of the filled PCM corresponds to the desired room temperature. The constant temperature level ensures optimal air conditioning of the buildings. The tubes used are also suitable for energy distribution. The surface of the tube is suitable for releasing energy via radiation. The shell arranged around the tube serves as a converter to specifically increase performance through convection. The air is generated by fans arranged in the shell.
