A method of providing a field test protocol for determining evaporator airflow verification for existing vapor compression cycle equipment.

Method for determining evaporator airflow verification

An apparatus and method for detecting faults and providing diagnostic information in a refrigeration system comprising a microprocessor, a means for inputting information to the microprocessor, a means for outputting information from the microprocessor, and five sensors.

Apparatus and method for detecting faults and providing diagnostics in vapor compression cycle equipment

A method for determining airflow through an evaporator coil in a vapor compression cycle by measuring the moist air conditions entering and leaving the coil, and various temperatures and pressures in the refrigerant of the vapor compression cycle. The mass airflow rate and the volumetric airflow rate are then determined.

Estimating evaporator airflow in vapor compression cycle cooling equipment

A process for estimating the capacity and the coefficient of performance by taking common measurements and using compressor manufacturer's performance data is presented. A process for determining a capacity index and an efficiency index for a vapor compression cycle relative to desired operating conditions.
