“…The height difference and density increase the potential of The entire loop thermosiphon system is controlled automatically, according to the heat flow with low operating noise and minimal electricity consumption. Another method of cooling is refrigeration units and air conditioners, which, unlike heat pipes, are directly dependent on an external energy source [42,43]. The designed cooling system with a heat pipe is a simple and highly efficient device that can be adapted to various operations in a wide range of parameters.…”

This paper deals with the experimental research and verification of a passive cooling system operating on the principle of a loop gravity heat pipe designed for cooling electrical cabinets. This type of cooling works automatically by changing the state of the working substance and thus saves energy consumption. Since the designed cooling system ensures heat transfer from the interior cabinet to the outdoor space, where the heat can naturally dissipate to the surroundings, it is dustproof. The heat pipe consists of an innovative evaporator concept designed to minimize liquid and vapour phase interference in the refrigeration circuit. The aim of the research was to experimentally determine the limit performance parameters of the refrigeration system for different volumes of working medium in the evaporator and decrease heat loss in the cabinet interior. The designed device was verified experimentally and by mathematical calculations as well. The greatest benefit of the work is that the cooling device was able to ensure temperature conditions inside the electrical enclosure at a heat load of 2000 W under 60 °C, 1500 W under 55 °C, 1000 W under 50 °C, 750 W under 45 °C and 500 W under 40 °C.

“…Passive-evaporative cooling will make the case worse because of the high relative humidity in humid areas [Hui & Cheung 2009, Doulos et al 2004, Vangtook & Chirarattananon 2007. Many researchers noted that humidity is not the only factor aff ecting the outdoor microclimate control, since the energy saving and type of energy used are also relevant [Hong Yuping et al 2008, Chàfer et al 2020. Recently, the outdoor air conditioning received a huge interest as the world cup organizing activity was assigned to one of the Gulf countries, i.e.…”

This research proposed an integrated eco-system for conditioning an outdoor public area (park or sport) in a hothumid environment. It is accomplished by the use of a dehumidifier control machine driven by renewable solar power; after which air is distributed throughout a ducting system. The system will harvest moisture from the air, utilize it for drinking water production and plants irrigation as well as deliver low temperature, low humidity ratio air for controlling the outdoor air, which results in a comfortable outdoor relative humidity and temperature (24 °C, 50% RH). The Integrated Eco-Friendly Cooling System (IEFCS) is a sustainable self-dependent in energy and water sources. It provides a positive impact on the microclimate of the site, assists in night illumination, supplies water for drinking, plant irrigation, and allows people to enjoy a thermally comfortable atmosphere. The advantages include low maintaining cost as well as the possibility to be scaled and implemented anywhere according to the selected location.
