Three rules of thermal parameters of air conditioning unit and a new method to establish performance curves

Based on experimental results and theoretical analyses, expounds the three rules of thermal parameters of air conditioning units: there exists a unique correlation rule between the inlet and outlet air wet bulb temperature of an air conditioning unit; for a given air conditioning unit at a given air rate, its wet bulb temperature drop equals to a constant; the inlet and outlet air relative humidity of an air conditioning unit abides by unique correlation rules. According to the three rules of thermal parameters and focusing principal of air handling line, proposes a new method to establish thermal performance parameter curve of an air conditioning unit with one certified test point.
