采用国际知名品牌全封闭涡旋式压缩机,蒸发器铜管采用内外螺纹式增强管。铜管表面有螺纹，铜管外表面光滑、冷却效果好，不结露，冷量损失少。冷凝器加工成梯形低肋管，增强传热能力，铜管表面光滑，使水压降低，易清洗保养。保护系统装置有：压缩机延时启动保护器、过载保护器、高低压保护器、温度控制开关等确保机组的正常运行。

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.
