2. Passive cooling - Wikipedia

   en.wikipedia.org/wiki/Passive_cooling

   Passive cooling covers all natural processes and techniques of heat dissipation and modulation without the use of energy. [1] Some authors consider that minor and simple mechanical systems (e.g. pumps and economizers) can be integrated in passive cooling techniques, as long they are used to enhance the effectiveness of the natural cooling process. [7]

3. Ventilative cooling - Wikipedia

   en.wikipedia.org/wiki/Ventilative_cooling

   Ventilative cooling is the use of natural or mechanical ventilation to cool indoor spaces. [1] The use of outside air reduces the cooling load and the energy consumption of these systems, while maintaining high quality indoor conditions; passive ventilative cooling may eliminate energy consumption.

4. Radiant heating and cooling - Wikipedia

   en.wikipedia.org/wiki/Radiant_heating_and_cooling

   Radiant systems are less common than all-air systems for cooling, but can have advantages compared to all-air systems in some applications. [ 10 ] [ 11 ] [ 12 ] Since the majority of the cooling process results from removing sensible heat through radiant exchange with people and objects and not air, occupant thermal comfort can be achieved with ...

5. Natural refrigerant - Wikipedia

   en.wikipedia.org/wiki/Natural_refrigerant

   Carbon dioxide requires higher pressures to be able to condense within the cooling system, meaning that it has to be pressurized more than the other natural refrigerants. [22] It can require up to 200 atmospheres to achieve adequate pressure for condensation. [23] Refrigerant systems using carbon dioxide need to be built to withstand higher ...

6. Passive house - Wikipedia

   en.wikipedia.org/wiki/Passive_house

   In passive house buildings, the cost savings from replacing the conventional heating system can be used to fund the upgrade of the building envelope and the heat recovery ventilation system. With careful design and increasing competition in the supply of the specifically designed passive house building products, in Germany it is currently ...

7. Ionocaloric refrigeration - Wikipedia

   en.wikipedia.org/wiki/Ionocaloric_refrigeration

   In conclusion, the ionocaloric refrigeration cycle represents a promising approach for efficient and eco-friendly cooling systems. Notably, the use of specific ionocaloric materials such as the ethylene carbonate-sodium iodide system and NaI, known for their high solubilities and ionic conductivity, further enhances this innovative technology's ...
