傳統上一般家用除濕機之除濕方式是以冷媒壓縮機系 統來冷凝空氣中之水氣,以達到室内空氣乾燥之目的。但 是由於使用CFC冷媒所衍生的臭氧層破壞問題,開發進一 步取代冷煤使用的除濕技術,則是愈來愈受到重視的技術 項目。因此,家電型除吸附式除濕機也逐漸佔有一席之地, 一般而言吸附式除濕機是藉由除濕輪吸附室内空氣水氣, 然後再由再生側進行水氣脫附,再生侧的高溫高濕空氣導 入熱交換器中進行冷凝,以集水盒收集由空氣中去除的水 分,達到家用除濕之目地。由於除濕輪除濕機以除濕輪吸 濕的特性完成除濕機制,具有不受環境氣體溫度及溼度條 件限制,並且不需使用傳統的壓縮機,因此具有低噪音及 避免冷煤使用等技術優勢。 在吸附式除濕機中,再生側的高溫高濕空氣進入冷凝 裝置後,與管外低溫的除濕側空氣進行熱交換,冷凝裝置 内的高溫高濕空氣即可冷凝成液態水。因此冷凝裝置所具 有冷凝高溫高溼再生氣流的能力,則成為家用型吸附除濕 機除濕性能表現的影響關鍵。對冷凝裝置而言,一般冷媒 5 1354755Traditionally, the dehumidification method of a general household dehumidifier is to use a refrigerant compressor system to condense moisture in the air to achieve indoor air drying. However, due to the destruction of the ozone layer derived from the use of CFC refrigerant, the development of a dehumidification technology that replaces the use of cold coal is an increasingly important technology project. Therefore, the household appliance type adsorption dehumidifier has gradually occupied a place. Generally, the adsorption type dehumidifier absorbs indoor air moisture by the dehumidification wheel, and then dehydrates the water and gas by the regeneration side, and the high temperature and high humidity air on the regeneration side. It is introduced into the heat exchanger for condensation, and the water removed by the air is collected by the water collecting box to achieve the purpose of household dehumidification. Since the dehumidification wheel dehumidifier completes the dehumidification mechanism with the characteristics of the dehumidification wheel moisture absorption, it is not restricted by the ambient gas temperature and humidity conditions, and does not require the use of a conventional compressor, so it has the technical advantages of low noise and avoiding the use of cold coal. In the adsorption type dehumidifier, the high-temperature and high-humidity air on the regeneration side enters the condensing device, and exchanges heat with the dehumidifying side air outside the pipe, and the high-temperature and high-humidity air in the condensing device can be condensed into liquid water. Therefore, the ability of the condensing unit to condense the high-temperature and high-humidity regeneration gas stream is the key to the dehumidification performance of the household adsorption dehumidifier. For condensing units, general refrigerant 5 1354755
壓縮機系統都是以金屬銅鋁管外加鰭片以增強空氣側熱傳 能力為設計。但由於重量及成本考慮,如圖一所示,一般 市售吸附除濕機其所使用冷凝盤1的材質皆為導熱係數較 低的塑膠,冷凝盤1之本體是由塑膠PP材質吹模一體成 型,管外亦無鰭片設計。在該冷凝盤1之底側,設置由兩 開口 10與11,以提供氣流進出。該冷凝盤1係由複數個 中空直管12、14與至少一中空橫管13相連通,中空直管 12與中空直管14並不是一對一的配置,例如:從一中空 直管12進入該中空橫管13之氣流並不一定要從相對應之 中空直管14流出。吸附除濕機中冷凝裝置以交錯式氣對氣 (cross flow type)進行熱交換,冷端為管外室内空氣,熱 端為管内局温ifj濕空氣。 一般而言,塑膠材質熱導係數較低,管内外亦無鰭片 可增強空氣侧熱傳,理論上塑膠製之冷凝裝置其材質與面 積不佳,但由於在吸附式除濕機中,再生側風量熱端質量 流率很低,相對熱交換容積也不高,因此只要熱傳效益 (heat exchange effectiveness, 〇夠就會有熱傳效果出 現。因此判定熱交換器能力不能只單看外觀,須搭配操作 條件一起評判。只要操作風量是在須求範圍内,塑膠製之 冷凝裝置是一項簡單低成本選擇。因此上述的限制條件 下,如何以構型設計提升塑膠冷凝裝置的熱傳效益,將大 幅影響吸附除濕機的除濕性能表現,以及國際市場競爭力。 【發明内容】 本發明提供一種冷凝裝置及其除濕裝置,其係以複數 6The compressor system is designed with metal copper and aluminum tubes plus fins to enhance the heat transfer capability on the air side. However, due to weight and cost considerations, as shown in Figure 1, the condensate disc 1 used in the general commercial adsorption dehumidifier is made of plastic with a lower thermal conductivity. The body of the condensing disc 1 is integrally molded by a plastic PP material. There is no fin design outside the tube. On the bottom side of the condensing pan 1, two openings 10 and 11 are provided to provide air in and out. The condensing tray 1 is connected to at least one hollow horizontal tube 13 by a plurality of hollow straight tubes 12, 14. The hollow straight tube 12 and the hollow straight tube 14 are not in a one-to-one configuration, for example, entering from a hollow straight tube 12 The air flow of the hollow cross tube 13 does not have to flow out from the corresponding hollow straight tube 14. The condensing device in the adsorption dehumidifier exchanges heat in a cross-flow type with a cross-flow type, the cold end is the indoor air outside the tube, and the hot end is the ambient temperature ifj wet air inside the tube. In general, the thermal conductivity of plastic materials is low, and there are no fins inside and outside the tube to enhance the heat transfer on the air side. Theoretically, the material and area of the condensing device made of plastic are not good, but in the adsorption dehumidifier, the regeneration side The mass flow rate of the hot end of the air volume is very low, and the relative heat exchange volume is not high. Therefore, as long as the heat exchange effect (heat exchange effectiveness, there will be a heat transfer effect), therefore, the heat exchanger capacity cannot be determined only by the appearance. It is judged together with the operating conditions. As long as the operating air volume is within the required range, the plastic condensing device is a simple and low-cost option. Therefore, under the above-mentioned restrictions, how to improve the heat transfer efficiency of the plastic condensing device by the configuration design, The invention will greatly affect the dehumidification performance of the adsorption dehumidifier and the competitiveness of the international market. SUMMARY OF THE INVENTION The present invention provides a condensing device and a dehumidifying device thereof, which are plural 6
