20.500.12556/RUL-145779 Prezračevanje v avtodomih Ventilation in motorhomes V zadnjih letih se daje velik povdarek na prezračevanje in izgube, ki pri tem nastanejo. Začenjamo se zavedati potrebe po zagotavljanu ugodja v prostoru. Medtem ko to pri hišah že dobro napreduje, so vozila oz. premični domovi v zaostanku. Ker imamo ob uporabi teh vozil ponavadi vedno skrajnosti visokih in nizkih temperatur, se vprašamo, kakšno prezračevanje bi bilo najbolj smotrno izbrati. Je to naravno, morda prisilo ali pa se izplača poizkusiti z rekuperacijo. V diplomski nalogi smo izmerili zrakotesnost takega vozila z meritvami s sledilnim plinom in z meritvijo povišanja CO2 prek noči, v primeru, da ni bila uporabljena nobene oblika prezračevanja. Preizkusili smo tudi učinkovitost prezračevanja z ventilatorjem. Tudi to meritev smo izvedli s sledilnim plinom. Poleg tega smo primerjali še različne metode za izračun izmenjave zraka. Na podlagi meritev smo ugotovili, da zaradi majhnega prostora v bivalnih vozilih za vstrezno prezračevanje potrebujemo veliko število izmenjav zraka. Tako da bi bilo najbolj smotrno izbrati prezračevanje z rekuperacijo. In recent years, great emphasis has been placed on ventilation and the losses that arise from it. We are starting to realize the need to provide comfort in space. While this is already progressing well with houses, vehicles or mobile homes in backlog. Since when using these vehicles we usually always have extremes of high and low temperatures, we ask ourselves what kind of ventilation would be the most expedient to choose. Is it natural, maybe forced, or is it worth trying recuperation. In diploma thesis, we measure the air tightness of such a vehicle by measurements with a tracer gas and by measuring the increase of CO2 overnight in case that no form of ventilation was used. We also tested the efficiency of ventilation with a fan. This measurement was also performed with a tracer gas. In addition, we compared different methods for calculating air exchange. Based on the measurements, we found that due to the small space in motorhomes, we need a large number of air exchanges for adequate ventilation. So it would be most expedient to choose ventilation with recuperation. prezračevanje avtodom zrakotesnost učinkovitost prezračevanja sledilni plin kakovost zraka ventilation motorhome airtightness ventilation efficiency tracer gas air quality true false false [U.
