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

Abstract: A computerized hardware and software system and a method for processing and storing measured data from various inputs (sensors) that reduces the data memory requirements and data transmission requirements of heating, ventilation, air conditioning, and/or refrigeration systems (HVAC&R) by creating a more compact data structure that retains data resolution, as required, based on the intended use of the measured data. The system and method are especially applicable to data processing and storage associated with the monitoring of such thermal equipment and systems but may be used in other data collection of other types of systems where system performance monitoring is desired.

Abstract: 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.

Abstract: 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.
