The assessment model can be used for sizing the heating and cooling equipment and for evaluating the transient thermal responses of shelters under specified initial heat-up and cool-down conditions. This model differs from standard HVAC load models in theform of the transient responses that can be predicted for the shelter. Currently available commercial and public-domain HVAC models predict transient-load variations and energy usage based upon a fixed inside design temperature. Computer codes such as TRNSYS can predict transient indoor conditions, but require detailed input, which is usually not available for thetypical shelter. The new, shelter environmental assessment model has the ability to predict inside temperature as a function of variations in environment condition, HVAC equipment performance, and inside load conditions. The algorithms use a multi node lumped capacity model for the shelter walls, the equipment and the air inside the shelter, since each of these elements has an energy-storage capacity. The model includes provisions for modeling camouflage netting as a thermal radiation shield having a negligible energy-storage capacity. Therefore, radiation-shield temperatures are computed from iterative, steady-state energy balances for each time step. The unknown temperatures for the elements with heat capacity are calculated ateach point in time using a \"marching\" solution combined with the radiation-shield temperatures. The model is designed to accommodate the energygains from equipment and personnel, and HVAC equipment operational features, with weather data for a specific location or from standard outdoor environmental conditions"},{"@xml:lang":"sl","#text":"Kot osnova modela za okoljsko vrednotenje prenosnih zavetij je bil razvit matematični algoritem. Model vrednotenja lahko uporabimo za načrtovanje ogrevalne in hladilne opreme ter za oceno prehodnih toplotnih odzivov zavetij v časovno neustaljenih razmerah okolice. Model se razlikuje od klasičnih modelov KGH (klimatizacija, gretje in hlajenje) v prehodnih odzivih, ki jih lahko vključimo v analizo zavetja. Za javno in poslovno uporabo so trenutno dostopni modeli, s katerimi določimo spremembe prehodnih obremenitev in rabo energije na podlagi določene računske notranje temperature. Z računalniškimi programi, kakrsen je npr. TRNSYS, lahko določimo prehodne pogoje v notranjosti, vendar zato potrebujemo natančne vstopne podatke, ki za značilna zavetja običajno niso na voljo. Z novim modelom okoljskega vrednotenja zavetij lahko določimo notranjo temperaturo v odvisnosti od razmer v okolici, delovanja sistemov KGH in notranjih virov. V algoritmih je za stene zavetja, opremo in notranji zrak uporabljen večvozlisčni model, saj se elementi med seboj razlikujejo po svoji toplotni vsebnosti. V model je vključen zastor, obravnavan kot toplotni ščit, z zanemarljivo zmožnostjo shranjevanja energije.Zato izraeunamo temperature sevalne zasčitne mreze za vsak časovni korak iz iterativnih energijskih bilanc pri nespremenljivih razmerah. Neznane temperature za vsakega od elementov z zmoznostjo hranjenja energije izračunamo za vsako točko v času z uporabo koračne funkcije, upostevajoč temperaturo sevalnega sčita. Model je zasnovan tako, da prilagodi toplotne dobitke opreme in osebja ter delovne značilnosti sistemov KGH vremenskim razmeram za določen kraj ali običajnim zunanjim razmeram"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-7I86WOHY","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-7I86WOHY"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-7I86WOHY/02b7212a-4d74-4804-b908-c3ba7f0bb48f/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Ljubljani, Fakulteta za strojništvo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-7I86WOHY/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-7I86WOHY"}}}}
