In recent years, the number and volume of public buildings have been increasing sharply, which has led to an increase in the working capacity of HVAC systems in public buildings. This paper analyzes and tests a heat recovery unit in an office building in Sichuan Province, China. The fresh air input temperature, the fresh air output temperature and the exhaust air temperature of the heat recovery unit in January in 2018 are analyzed. The positive and negative benefits are calculated, and thus the energy saved by the system during the test is obtained.
