最適合冬日抱團取暖的「神器」來了Here Comes a Great Heater in Winter

銅手爐、熱水袋、湯婆子並稱冬季禦寒的三大寶。隨著生活品質的提升，空調、取暖器逐漸取代了這批老物件，成為近年來取暖的主要方式。從目前來看，空調+取暖器，是當前大多數家庭過冬的首選。

In old times, copper hand warmer, hot water bag and hot water bottle were necessary in cold winter.With theimprovement of living quality, the air conditioner and heater are gradually replacing the old ones, becoming a main way for heating.

消費需求改變，空調業迎來「暖冬時代」

Demand changes, good time of air conditioning industry comes

取暖器可使房屋部分空間內的溫度有所提升，但耗電多且不利於空氣流通，而空調是把外面空氣的溫度提高後換入屋內，利於空氣流通。漸漸的，空調走進了千家萬戶，它的出現也讓炎熱夏日變得清涼，讓寒冷冬日變得溫暖。

A heater can increase the room temperature, but it consumes much electricity and is not good for ventilation. While the air conditioner can notonly increase the indoor temperature, but also ventilate the indoor air. Gradually, air conditioner walk into thousands of households, which makes the summer cooler and winter warmer.

空調產品琳琅滿目，風管機成後起之秀

Among so many types of air conditioner, duct type unit becomes an up-rising star

發展到今天，空調系統逐漸演變成多個分類，常見的有壁掛機、風管機、櫃體機、中央空調等，為人們帶來了更多選擇。在空調行業的發展歷程中，風管機結合了中央空調的舒適與高檔以及家用分體機安裝方便等優勢，成為近幾年新型的商用吊式空氣處理機組。

Nowadays, there are so many types of air conditioners for selection, such as wall-mounted type unit, duct type unit, floor standing type unit, central air conditioner, etc. In the development process of air conditioning industry, duct type unit has integrated central air conditioners』cozy experience and residential split type unit』s convenient installation method, becoming a new commercial ceiling type air conditioner in recent years.

風管機是隱藏式空調的簡稱，目前普遍採用的是1拖1的形式，風管機的內機安裝在天花板內部，可減少對室內空間的佔用，保證了室內整體裝修的美觀，解決了掛機、櫃機裸露在外面影響美觀的問題。在造價方面，風管機比壁掛機貴，但相比中央空調又便宜了不少。同時，走管的長度比普通家用空調要長，安裝比較靈活，客戶可根據實際需求選擇安裝一台或多台。

Duct type unit is also called concealed type unit. Generally it adopts U-match connecting mode, and its indoor unit isinstalled inside the ceiling, which reduces the installation space and will notimpact the decoration. As for the cost, duct type unit is more expansive than that of wall-mounted unit, but it』s much less expensive than that of central air conditioner. Moreover, the length of pipes is longer than that of general residential air conditioner, which can be installed flexibly by meeting user』s requirement.

將「芯」比「芯」，風管機也需要一顆好心臟

Duct type unit also needs a good heart.

壓縮機作為空調的心臟，空調整機的能效在很大程度上取決於壓縮機的能效。繼熱泵專用壓縮機之後，格力凌達又研發了一款風管機專用壓縮機。使用該壓縮機後，格力風管機與普通風管機相比，平均制熱效果提升15%，保證室內的供暖，室溫波動減小，人體感受更加舒適。

Compressor is the heart of an air conditioner. Efficiency of an air conditioner largely depends on the energy efficiency of compressor. After developing the compressor specially for the heat pump, Gree Landa further developed a special compressor for duct type unit. With such compressor, average heating effect of Gree duct type unit is increased by 15%, defrosting period of outdoor unit is prolonged by 25%, and the room temperature fluctuationis reduced, thus the indoor heating is ensured.

（2）採用高品質材料：新型耐磨材料，延長壓縮機使用壽命。Adopt high-quality material: new wear-resistant material forprolonging service life of compressor.

優化油路設計Optimizeoil circuit design：

（1）採用CFD兩相流，研究注油量對長期可靠性的影響；優化設計潤滑流路。Using the CFD two-phase flow to optimize and design lubrication circuit.

（2）特別優化油路設計，確保惡劣工況下壓縮機可長期正常運行。Specially optimize the oil circuit design to ensure long-term andnormal operation of compressor under bad working conditions.

（3）增加壓縮機冷凍油灌注量，保證風管系統運行平穩可靠。Increase charging amount of refrigeration oil for compressor toensure reliable operation of system.

其他方面優化Other improvements：

（1）180o正波弦空間適量轉換技術，擁有較寬的可調範圍。180°sine wave space conversion technology，with wide adjustable range.

（2）低功耗待機設計，更高效節能。Low power standby design,more efficient and energy-saving.

（3）結構緊湊、佔用極小空間、安裝便捷；Compact structure for easy installation.

凌達空調風管機專用壓縮機現已應用成熟，實現量產，並以優異的性能吸引了行業的關注。

Landa duct type unit specialized compressor has been widely used and put into mass production, which has attracted the attention of insiders with its excellent performance.
