Abstract: With the frequent occurrence of extreme weather worldwide, summer temperatures are getting higher and winter temperatures are getting lower, and outdoor temperatures are about to exceed human tolerance. In order to change extreme weather, China has focused on the dual carbon goal and vigorously advocated for low-carbon environmental protection. As an effective means of adjusting air temperature, air conditioners have become essential household appliances for every household. This article takes a 30 K four direction embedded air conditioner as an example to conduct multi-level optimization of the refrigerant type, condenser configuration, compressor displacement, and throttling element modules of the air conditioner, so that the air conditioner has relative advantages in terms of price and green low-carbon. Performance related tests are also conducted on the optimized air conditioner, the test results meet the ability and energy-saving standards.
