摘要
Expanded temperature split, superheat, enthalpy, humidity, and wet-bulb tables are created and used to determine recommended refrigerant charge and airflow adjustments. Previously unknown enthalpy split values are introduced and calculated in a defined region and then extrapolated using a nonlinear curve fit for undefined regions. Undefined target temperature split values are then calculated from a relationship between temperature split and enthalpy split. Previously undefined superheat values are extrapolated using a nonlinear curve fit from a defined region to obtain superheat values for undefined regions. The expanded temperature split and superheat tables are used during setup or maintenance to calculate refrigerant and/or airflow adjustments for optimal performance of the cooling system in previously undefined operating regions. Previously unknown energy efficiency ratio improvement methodologies are introduced and calculated based on measurements of refrigerant charge and airflow improvements for air-conditioners and heat pumps (in cooling mode).
