Cities Need Cleaner Heating SolutionsHigher living standards means more people want solutions for cooling in summer and heating in winter. Air

cooled heat pump unit is an excellent choice for meeting these requirements. However, due to technology

bottlenecks, the heating e�ect in winter is limited by ambient temperature. Meanwhile, frequent shutdowns

make users uncomfortable when switching between heating and cooling because of defrosting.

Midea large capacity air cooled scroll chiller uses clean energy to produce heat instead of traditional coal-�red

boilers. The wider range of ambient temperature, strong heating e�ect at low temperatures in winter, intelligent

defrosting, and small outlet water temperature �uctuations heat cold areas for greater comfort. The green

R410A refrigerant and low operating noise minimize environmental impact. The product features a modular

design for seamless connections and reduced installation space, bringing more bene�ts to customers.
