Part Load Performance Data
This document provides detailed part load performance data for the Temperzone OPA 171 Econex (Pro) R32 ducted packaged unit. The data is crucial for understanding the unit's efficiency and output under various operating conditions.
Key Definitions
- TC: Total Capacity (kW)
- SC: Sensible Capacity (kW)
- PI: Power Input (kW)
- E.A.T.: Entering Air Temperature (°C)
- G: Gross Capacity (kW), based on nominal air flow.
- N: Net Heating Capacity (kW) allowing for average defrost.
Nominal Air Flow: 900 l/s. Total Capacity figures are gross and do not include allowance for fan motor heat loss.
Cooling Capacity Performance Tables
The document contains comprehensive tables detailing the cooling performance of the OPA 171 Econex (Pro) R32 unit. These tables present Total Capacity (TC), Sensible Capacity (SC), and Power Input (PI) for cooling. Data is organized by Indoor coil Entering Air Temperature (E.A.T.) and Outdoor coil Entering Air Temperature (°C DB), across various operating capacity levels, including Maximum Capacity, Nominal Capacity, Maximum less 25%, and Maximum less 50%. These tables allow for precise selection and analysis of the unit's performance under specific environmental conditions.
Heating Capacity Performance Tables
Similarly, detailed tables are provided for heating performance, showing Gross Capacity (G), Net Heating Capacity (N), and Power Input (PI). These tables also cover a range of indoor and outdoor air temperatures and are categorized by the unit's operating capacity levels.
Indoor Air Flow Correction Factors
The following table outlines correction factors for indoor air flow at nominal conditions, indicating how capacity changes with variations in air flow:
| Indoor Air Flow | ||||
|---|---|---|---|---|
| –20% | –10% | Rated | +10% | |
| Total Cooling Capacity | 0.950 | 0.975 | 1.000 | 1.025 |
| Sensible Cooling Capacity | 0.900 | 0.950 | 1.000 | 1.050 |
| Heating Capacity | 0.990 | 0.995 | 1.000 | 1.005 |
