Doerfler, Associate Department Head COMMITTEE MEMBER: Jacob Feldman, Professor iii WIND-CHIMNEY Integrating the principles of a wind-catcher and a solar chimney to provide natural ventilation Fereshteh Tavakolinia Abstract This paper suggests using a wind-catcher integrated with a solar-chimney in a single story building so that the resident might benefit from natural ventilation, a passive cooling system, and heating strategies; it would also help to decrease energy use, CO2 emissions, and pollution. This system is able to remove undesirable interior heat pollution from a building and provide thermal comfort for the occupant. The present study introduces the use of a solar-chimney with an underground air channel combined with a wind-catcher, all as part of one device. Both the wind-catcher and solar chimney concepts used for improving a room’s natural ventilation are individually and analytically studied. This paper shows that the solar-chimney can be completely used to control and improve the underground cooling system during the day without any electricity.

M. Skłodowskiej-Curie 62, 59-301 Lubin, Poland; [email protected] (M.P.); [email protected] (W.S.) * Correspondence: [email protected]; Tel.: +48-7132-028-68 Received: 12 November 2020; Accepted: 9 December 2020; Published: 18 December 2020 Abstract: In underground mines, mobile mining equipment is critical for the production system. The microenvironment inside the mobile machine may cause exposure to strongly polluted mine air, which adversely affects the health and working performance of the operator. Harmful pollutants may access the cabin together with the ventilation air delivered from the machine’s surroundings. This work proposes a solution that is able to ensure that the air for the machine operator is of proper quality. The proposal emerged from an analysis of the compliance of cabins of mobile machines working underground in mines with occupational health and safety (H&S) standards. An analytical model of air quality in a well-mixed zone was utilized for this purpose. The cabin atmosphere was investigated with regard to the concentration of gaseous species in the surrounding air, the cabin ventilation rate, and human breathing parameters. The analysis showed that if currently available ventilation approaches are used, compliance with multiple H&S standards cannot be attained inside the cabin if standards are exceeded in the surroundings of the machine.

  • Indoor Air Quality
    Indoor Air Quality Poor indoor air quality can cause a stuffy nose, sore throat, coughing or wheezing, headache, burning eyes, or skin rash. People with asthma or other breathing problems or who have allergies may have severe reactions. Common Indoor Air Pollutants Poor indoor air quality comes from many sources, including: » Tobacco smoke » Mold » Pollen » Allergens such as those from cats, dogs, mice, dust mites, and cockroaches » Smoke from fireplaces and woodstoves » Formaldehyde in building materials, textiles, and furniture » Carbon monoxide from gas furnaces, ovens, and other appliances » Use of household products such as cleaners and bug sprays » Outdoor air pollution from factories, vehicles, wildfires, and other sources How to Improve Indoor Air Quality » Open windows to let in fresh air. • However, if you have asthma triggered by outdoor air pollution or pollen, opening windows might not be a good idea. In this case, use exhaust fans and non-ozone-producing air cleaners to reduce exposure to these triggers. » Clean often to get rid of dust, pet fur, and other allergens. • Use a vacuum cleaner equipped with a HEPA filter. • Wet or damp mopping is better than sweeping. » Take steps to control mold and pests. » Do not smoke, and especially do not smoke indoors. If you think poor indoor air is making you sick, please see or call a doctor or other health care provider. About CDC CDC is a federal public health agency based in Atlanta, GA.

We now need to identify sustainable design investments for a very uncertain future of expanding populations, scarcer resources and climate change. Buildings in the Iranian desert regions are constructed according to the specific climatic conditions and differ with those built in other climates. Desert buildings are equipped with air traps, arched roofed, water reservoirs with arched domes and ice stores for the preservation of ice. The operation of modern coolers is similar to the old Iranian air traps which were built at the entrance of the house over underground water reservoirs or ponds built inside the house.
