EQUIPMENT SELECTION

From Application to the Right Equipment Family

How to Size a Condensing UnitLoad, temperature, ambient, refrigerant and system matching. Medium vs Low TemperatureChoose the family from the application conditions. How to Match Condensing Unit and Unit CoolerCompare both sides at the same operating point. How to Size a Unit CoolerCapacity, air distribution, defrost and matching. Airflow and Air ThrowRelate the unit cooler to actual room geometry. Defrost SelectionEspecially important in low-temperature applications.

MODEL DATA

Freskool Medium-Temperature Condensing Units

These profiles make model data discoverable without turning horsepower into a false capacity claim. Final selection still depends on refrigeration load and operating point.

ENGINEERING FUNDAMENTALS

Variables That Change Equipment Selection

Refrigeration LoadMore than room size: transmission, infiltration, product and internal loads. R448A vs R449ACompatibility, operating point and project requirements. Voltage and Electrical ServiceConfirm voltage, phase and frequency before finalizing the model. Fixed vs Variable SpeedCompare control strategy against the actual load profile.
