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.
