Variasi Tekanan Kerja Suction Compressor Terhadap Kinerja Ac Split dengan R290
Bibliographic record
Abstract
Telah dilakukan studi eksperimen kinerja R290 pada AC split basis R22. Karena dampak negative terhadap lingkungan oleh klorin dari penggunaan R22 yang menyebabkan terjadinya penipisan lapisan ozon maka kesepakatan montreal 1997 memutuskan untuk menghapus penggunaan R22. Zat alami R290 yang memiliki ODP nol dan GWP yang dapat diabaikan dipandang memiliki potensi yang besar sebagai alternative pengganti R22. Metode penelitian ini adalah menguji R290 pada AC split 1 PK basis R22 dengan memberikan variasi tekanan kerja pada suction kompresor berturut-turut sebesar 60 psi, 70 psi dan 80 psi. Pada masing-masing tekanan kerja suction kompresor yang diberikan diamati pengaruhnya terhadap kapasita pendinginan, kerja kompresor dan COP. Selanjutnya dengan metode yang sama diuji juga R22. Akhirnya kinerja R290 dan R22 dibandingkan. Hasil penelitian menunjukan bahwa kapasitas pendinginan R290 dan R22 meningkat terhadap peningkatan tekanan kerja suction yang diberikan. Semakin tinggi tekanan kerja suction, memberikan beda kapasitas pendinginan antara R290 dan R22 yang semakin besar. Perbedaan kapasitas pendinginan antara R22 dan R290 rata-rata mencapai 13,4%. Sementara itu, kinerja COP R290 mencapai 15,2 % lebih rendah disbandingkan dengan R22.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
