本文主要以實驗方法對硬銲型板式熱交換器的凝結性能測試與分析。工作流體為水對冷媒R22。測試的板式熱交換器有兩種型式,分別為K070與K050。此兩種熱交換器配合壓縮式冷凍循環系統作實地運轉測試分析其性能。
本研究架設一額定能力為2冷凍噸之壓縮式冷凍空調系統,進行板式熱交器之凝結測試。測試條件依美國AHRI (Air-Conditioning, Heating, and Refrigeration Institute) 450冷凝器標準進行實驗。由實驗結果得知,分別計算凝結過程中之過熱段、兩相區以及過冷段之熱傳量、對數平均溫差、面積以及熱傳係數將會因為計算過程過於繁複而使得誤差變大。故本研究修正計算方式,計算整體熱交換器的凝結性能。以供未來相關研究人員使用設計參考。
This Study makes an experiment on condensing heat transfer and pressure drop performance of a plate heat exchanger. The working fluid is R22 in the study. There two types plate heat exchangers which are K070 and K050 have been test. The test has been operating in a compressible chiller system.
In the study, 2 RT capacity compressible chiller system has been build to make condensing experiment. Operating conditions according to AHRI 450 standard(Air-Conditioning, Heating, and Refrigeration Institute). The experimental results shown the accuracy is very large while calculating heat transfer coefficient of superheat, two phases and subcool region respectively. The study modified the calculating method to estimate the overall condensing heat transfer coefficient. The results will provide some designer information for designers of plate heat exchanger.
