采用國際知名品牌全封閉渦旋式壓縮機,蒸發器銅管采用內外螺紋式增強管。銅管表面有螺紋，銅管外表面光滑、冷卻效果好，不結露，冷量損失少。冷凝器加工成梯形低肋管，增強傳熱能力，銅管表面光滑，使水壓降低，易清洗保養。保護系統裝置有：壓縮機延時啟動保護器、過載保護器、高低壓保護器、溫度控制開關等確保機組的正常運行。

It adopts an internationally-known brand full-closed scroll compressor, and the evaporator copper tube adopts internal and external screw-type reinforcing tubes. The surface of the copper pipe is threaded, the outer surface of the copper pipe is smooth, the cooling effect is good, no condensation occurs, and the loss of the cooling capacity is small. The condenser is processed into a trapezoidal low-ribbed tube, which enhances the heat transfer capacity. The surface of the copper tube is smooth, so that the water pressure is reduced, and it is easy to clean and maintain. Protection system devices include: compressor delay start protector, overload protector, high and low voltage protector, temperature control switch, etc. to ensure the normal operation of the unit.
