Aparato Experimental Para Avaliação Termo-Energética de Refrigerador Doméstico
Bibliographic record
Abstract
Os esforcos de pesquisa e desenvolvimento na area de Refrigeracao e Climatizacao aplicados ao uso de fluidos refrigerantes naturais nao esta associada somente a necessidade de preservacao do meio-ambiente em si, mas tambem apresenta grande importância na necessidade latente do aumento da eficiencia energetica dos equipamentos. Tal caracteristica e observada na Decisao XIX/6 do Protocolo de Montreal. Neste sentido, identificar fluidos refrigerantes alternativos de longo prazo que satisfacam todos os requisitos com relacao a performance dos sistemas e uma importante area de pesquisa. O objetivo do presente trabalho e analisar as normalizacoes existentes no Brasil, referentes a ensaios em refrigeradores domesticos, e desenvolver a montagem de um aparato experimental para estudo termo-energetico/performance de um refrigerador. Foi desenvolvido um aparato experimental consistindo de um refrigerador domestico de 219 L instrumentado com sensores de pressao, temperatura e corrente eletrica. Os sensores de temperatura e corrente eletrica sao conectados a um sistema de aquisicao de dados para o registro dos dados durante todo o tempo de ensaio. As indicacoes de pressao foram obtidas visualmente atraves de manifold digital. O aparato e adequado para a avaliacao termodinâmica e energetica de um equipamento de refrigeracao operando com fluidos refrigerantes sinteticos ou naturais (hidrocarbonetos), dentro da estrategia de drop-in, sem alteracao dos componentes mecânicos do sistema.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
