Friedrich Universal Heat Pump Capacity and Selection Data

Product Overview

This document provides extended capacity charts for Friedrich Universal Heat Pumps, covering models from 24k to 48k BTU, utilizing R-454B refrigerant.

The data presented includes detailed cooling and heating capacity tables based on various outdoor and indoor temperature conditions. It also outlines correction factors for piping length, height differences between units, and defrosting operations.

Capacity Characteristic Charts

The following charts detail the characteristics of outdoor unit capacity, corresponding with the operating ambient temperature of the outdoor unit. The data are based on the following conditions:

Pipe length / height difference: 25 ft. (7.6m) / 0 ft.(0m)
Compressor operating at rated inverter frequency
Indoor fan speed set to high fan speed
Capacity loss due to white frost and defrost operation is not included in these base tables.

Cooling Capacity Tables

Tables showing Cooling Capacity for various Air Handler units paired with Outdoor Condensers across different indoor and outdoor temperatures. Data includes Total Cooling Capacity (TC), Sensible Heat Capacity (SHC), and Power Input (PI).

To ensure correct unit selection, consider the farthest indoor unit.

NOTE:

Above data assumes height difference between indoor and outdoor units is 0m.
Minimize connection pipe length for optimal performance.
If the outdoor unit is installed higher or lower than the indoor unit, apply height correction factor additionally to length correction factor for cooling calculations.
For higher outdoor units, apply correction to cooling capacity. For lower outdoor units, apply correction to heating capacity.

Height Difference Correction Factor

The correction factor for height difference between indoor and outdoor units.

Height difference	16ft (5m)	33ft (10m)	108ft (30m)
Factor	0.01	0.02	0.025

Correction Factors According To Defrosting Operation

The heating capacity data excludes defrosting operation. Corrected heating capacity is calculated as: Defrost Correction factor x unit capacity.

Outdoor Temperature [°F (°C)DB]	-13 (-25)	-4 (-20)	5 (-15)	14 (-10)	23 (-5)	32 (0)	44.6 (7)	50 (10)	59 (15)
9K~60K	0.97	0.96	0.95	0.95	0.95	0.85	1.0	1.0	1.0

Diagram Description: A graph illustrating heating capacity over time. It shows periods of heating capacity interrupted by a reduction due to white frost. The cycle indicates a maximum defrost duration of 12 minutes within one cycle.

NOTE: The correction factor is not valid for special conditions like snowfall or operation in a transitional period.
