摘要

本研究主要針對窗型變頻式冷氣機性能分析探討，藉由改變冷媒充填量、毛細管長度以及壓縮機運轉頻率等系統參數來探討對性能上的影響，尋求改善本實驗樣機的性能以達到最佳化運轉模式。
實驗方法依CNS3615無風管空氣調節機與CNS14464無風管空氣調節機與熱泵之試驗法規範標準下，室外側維持溫度35℃DB、24℃WB，室內側維持溫度27℃DB、19℃WB進行相關實驗量測，包含冷凍循環各元件進出口冷媒溫度、運轉高低壓力、壓縮比、平均消耗電功率、能源效率比 (EER)及噪音測試。實驗結果顯示，變頻式冷氣機EER為2.76 kcal/h•W均比傳統定頻式2.38 kcal/h•W來得高，在降低噪音產生量也比定頻式優異；連續運轉6小時的總消耗電力為定頻式冷氣機的54％，預估夏季每月電費將可比定頻式冷氣機節約46％左右。
因此，在現今全球能源短缺的情況下，高EER又省能、安靜的窗型變頻式冷氣機，可提供消費者另一個優質的選擇。

Application of inverter on air-conditioning equipments, such as water chillers, multi-type split air-conditioners…etc. is more and more popular globally. Due to building space restriction, split units and window units sold in the Taiwan market is around 50-50 share. In other words, demand for window units is still strong at this stage. Inverters are installed on split units in most of application as compared with window units. This study analyzes operation performance of window type inverter unit and traditional fixed frequency room air-conditioner. Tests for energy efficiency ratio (EER), power consumption and operation noise level by following CNS 3615 and CNS 14644 are performed in an environmental control test lab. Experimental results show that power consumption of inverter unit is 46% lower than fixed frequency unit. EER is higher (2.76 vs 2.38) but noise level is lower. It is estimated that energy saving can be achieved up to 46% during summer season if inverter unit is installed instead of fixed frequency one.
