Patent ID: 8583384

Claim:
A method for adjusting refrigerant and airflow rates in air conditioning systems using expanded tables, the method comprising: calculating values to fill in undefined areas of conventional air conditioner lookup tables to obtain expanded air conditioner lookup tables, the calculating comprising: calculating supply air dry-bulb temperature ts from prior art temperature split at 100% relative humidity; calculating supply air saturation pressure p*ws at 100 percent relative humidity; calculating supply air wet-bulb temperature (w) for return air wet-bulb at 100% relative humidity and supply air dry-bulb temperature ts to calculate expanded supply air relative humidity (Table 6) and supply air wet-bulb (Table 7); calculating Enthalpy Split from return and supply air dry-bulb and wet-bulb temperatures; calculating polynomial regression functions for each return wet-bulb temperature as a function of return dry-bulb temperature; extrapolating expanded enthalpy split values using the polynomial regression functions for each return air wet-bulb temperature and dry-bulb temperature combination to calculate target enthalpy split (Table 5); and using prior art temperature split (Table 1), target enthalpy split (Table 5), and expanded supply air wet-bulb (Table 7), to calculate target temperature split (TS=tr−ts) and expanded target temperature split (Table 3); receiving inputted data, at least some of which is in the undefined areas of the conventional air conditioner lookup tables; calculating an amount of refrigerant to be added or removed from said air conditioning system using said inputted data and the expanded lookup tables, and adjusting the amount of amount of refrigerant in the air conditioning system based on the calculations.
