Optimización energética de los refrigerantes R152a, R1234yf, R290, R1270, R600a y R744, como alternativa al R134a en un armario de refrigeración vertical
Bibliographic record
Abstract
Con la entrada en vigor de la normativa Europea F-Gas (2014) y la posterior enmienda de Kigali al protocolo de Montreal (2019), los equipos frigoríficos autónomos han sufrido cambios para poder sustituir los refrigerantes originales R134a y R404A, a otras sustancias con menor impacto medioambiental tales como R290, R600a o incluso R744 (CO2). Sin embargo, existen otras sustancias que también pueden ser consideradas como alternativas, como es el caso de los fluidos puros R1270, R152a y R1234yf. En esta ponencia se analiza energéticamente cómo funciona un armario de refrigeración vertical autónomo, cuando la carga de refrigerante es optimizada para los fluidos anteriormente mencionados. Dicha optimización busca minimizar el consumo energético del equipo en unas condiciones ambientes de 30ºC y 60% (Clase climática III), manteniendo una temperatura promedio de producto en torno a 3ºC. Tomando como referencia el refrigerante R134a, los resultados obtenidos muestran un ahorro energético del 27.5 %, 26.3 %, 13.7 %, 3.9 % y 1.2 %, para los refrigerantes R290, R1270, R152a, R744 y R600a, respectivamente, mientras que el uso del refrigerante R1234yf, supone un incremento del 4. 1%.

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.
