Abstract: The energy efficiency of air conditioning units is the threshold for products in various countries, which directly determines product quality and is also a requirement for promoting energy-saving and dual carbon initiatives. From the technical point of view of improving the energy efficiency of the air conditioning system, a high energy efficiency product is designed from the perspective of box size and system component matching. Taking the 60K rooftop machine as an example, by selecting multiple system components and conducting multiple rounds of matching and coupling, the optimal combination of box size, wind field, and heat exchanger is ultimately achieved to determine the best design solution.
