The purpose of this standard is to establish an IEER and SCHE Method of Calculation for Water/Brine Source Heat Pumps. This standard utilizes

the Published, Certiﬁed Data, of performance standard ISO/AHRI/ANSI/ASHRAE 13256-1:1998, and includes the deﬁnitions; rating requirements;

minimum data requirements for Published Ratings; marking and nameplate data; and conformance conditions required.

RB SERIES ENGINEERING GUIDE

The performance standard AHRI/ASHRAE/ISO 13256-1 became effective January 1, 2000 and replaces AHRI Standards 320, 325, and

330. This new standard has three major categories: Water Loop (comparable to ARI 320), Ground Water (ARI 325), and Ground Loop (ARI

330). Although these standards are similar there are some differences:

Unit of Measure: The Cooling COP

The cooling efficiency is measured in EER (US version measured in Btu/h per Watt. The Metric version is measured in a cooling COP

(Watt per Watt) similar to the traditional COP measurement.

Water Conditions Differences

Entering water temperatures have changed to reflect the centigrade temperature scale. For instance the water loop heating test is

performed with 68°F (20°C) water rounded down from the old 70°F (21.1°C).

Air Conditions Differences

Entering air temperatures have also changed (rounded down) to reflect the centigrade temperature scale. For instance the cooling

tests are performed with 80.6°F (27°C) dry bulb and 66.2°F (19°C) wet bulb entering air instead of the traditional 80°F (26.7°C) DB

and 67°F (19.4°C) WB entering air temperatures. 80.6/66.2 data may be converted to 80/67 using the entering air correction table.

This represents a significantly lower relative humidity than the old 80/67 of 50% and will result in lower latent capacities.

Pump Power Correction Calculation

Within each model, only one water flow rate is specified for all three groups and pumping Watts are calculated using the following

formula. This additional power is added onto the existing power consumption.

• Pump power correction = (gpm x 0.0631) x (Press Drop x 2990) / 300

Where ‘gpm’ is waterflow in gpm and ‘Press Drop’ is the pressure drop through the unit heat exchanger at rated water flow in feet

of head.

Blower Power Correction Calculation

Blower power is corrected to zero external static pressure using the following equation. The nominal airflow is rated at a specific

external static pressure. This effectively reduces the power consumption of the unit and increases cooling capacity but decreases

heating capacity. These Watts are significant enough in most cases to increase EER and COPs fairly dramatically over ARI 320, 325,

and 330 ratings.

• Blower Power Correction = (cfm x 0.472) x (esp x 249) / 300

Where ‘cfm’ is airflow in cfm and ‘esp’ is the external static pressure at rated airflow in inches of water gauge.

ISO Capacity and Efficiency Calculations

The following equations illustrate cooling calculations:

• ISO Cooling Capacity = Cooling Capacity (Btu/h) + (Blower Power Correction (Watts) x 3.412)

• ISO EER Efficiency (W/W) = ISO Cooling Capacity (Btu/h) x 3.412 / [Power Input (Watts) - Blower Power Correction (Watts) + Pump

Power Correction (Watt)]

The following equations illustrate heating calculations:

• ISO Heating Capacity = Heating Capacity (Btu/h) - (Blower Power Correction (Watts) x 3.412)

• ISO COP Efficiency (W/W) = ISO Heating Capacity (Btu/h) x 3.412 / [Power Input (Watts) - Blower Power Correction (Watts) + Pump

Power Correction (Watt)]

Comparison of Test Conditions

Conversions:

Airflow (lps) = cfm x 0.472; Water Flow (lps) = gpm x 0.0631;

esp (Pascals) = esp (in wg) x 249; Press Drop (Pascals) = Press Drop (ft hd) x 2990

RB SERIES ENGINEERING GUIDE

The RB Series

Vertical RB Series

Models RBSV 006-070 (0.5-6 tons) Single Speed

Horizontal RB Series

Models RBSH 006-070 (0.5-6 tons) Single Speed

The RB Series raises the bar for boiler/tower applications by providing ﬂexibility and efﬁciency into a compact cabinet at a competitive price. A

compact cabinet is important when choosing a replacement heat pump. Many water source heat pumps of the 1980-90’s were relatively low

efﬁciency models with a small footprint. Once they are installed in a building and piping and ductwork is piped around the unit replacement with

a larger footprint is nearly impossible. The RB Series combines the high efﬁciency of 21st century product in a footprint that matches a 1980 heat

pump for easy replacement. The chart below shows a comparison of a typical 1980 legacy wshp and current competitor data versus the RB

Series.

This full range product offers all the standard commercial voltages using high efﬁciency rotary and scroll compressors along with either

3-speed permanent split-capacitor (PSC), 5-speed ECM, or variable speed ECM blower motors.

RB Series Highlights

• High efﬁciency performance

-With PSC Blower Motor Up to 14.0 EER and 4.7 COP (ISO/AHRI 13256-1-WLHP)

-With Variable Speed ECM Blower Motor Up to 14.7 EER and 4.9 COP (ISO/AHRI 13256-1-WLHP)

-With 5-Speed ECM Blower Motor Up to 14.7 EER and 4.9 COP (ISO/AHRI 13256-1-WLHP)

• Unrivaled cabinet footprint that can ﬁt most application requirements

-A four ton horizontal unit less than four feet long means the smallest horizontal cabinets in the industry!

• All-Aluminum riﬂed tube-and-ﬁn air coils are not susceptible to formicary corrosion.

• Dedicated 460V 5-Speed ECM does not require use of a neutral!

High Efficiency

The RB Series is a high efficiency water source heat pump

in a compact vertical and horizontal cabinet. The product

features highly efficient and reliable single capacity rotary scroll

compressors mated with large blowers. These blowers are driven

by efficient 3 speed PSC blower motors, 5-Speed ECM blower

motors, or highly efficient Variable Speed ECM blower motors.

Quiet Operation

All RB Series product incorporates several noise reduction

technologies and is ARI 260 sound rated using third party sound

testing. Room Noise Criteria Curves (NC Curve) may be calculated

using data from the ARI 260 ratings giving the engineer total

flexibility in assuring a quiet environment. Please refer to the

separate Sound Ratings and Performance Catalog concerning this

standard and RB Series sound performance data.

Super Quiet Option

An optional Super Quiet Sound Package is also available for a

modest cost and features multi-density laminate lined compressor

blanket designed to completely surround the compressor and

suppress low frequency noise.

Indoor Air Quality (IAQ)

All units feature several IAQ benefits:

• Corrosion-free composite double-sloped drain pan to

eliminate standing water and prevent bacterial growth

• Awashable surface on insulation in all air handler compartments

to allow cleanability and inhibit bacteria growth. Optional non-

fibrous closed cell insulation is also available for more sensitive

applications by special request through commercial sales..

• Open filter rail comes standard for non-ducted return

applications. Filter rail is field switchable from 1 in. to 2 in. [2.54

to 5.1 cm] for more filter options.

• Optional factory mounted, four sided, deluxe filter rack that is

field switchable from 1 in. to 2 in. [2.54 to 5.1 cm] is available for

ducted return applications.

• Standard supplied filter is a pleated MERV 4, 1 in. [2.54

cm]. An optional low static high efficiency 2 in. [5.1 cm]

MERV 13, for LEED certification points, is also available.

Flexible Control Options

The Aurora Base Control (ABC)

System is a complete residential

and commercial comfort system

that brings all aspects of the

HVAC system into one cohesive

module network. Aurora uses

the Modbus communication

protocol to communicate between

modules. Each module contains

the logic to control all features

that are connected to the module.

The Aurora Base Control (ABC) has two Modbus channels. The

first channel is configured as a master for connecting to devices

such as a communicating thermostat, expansion board, or other

satellite devices. The second channel is configured as a satellite for

connecting the Aurora Interface Diagnostic Tool (AID Tool).

The Aurora Interface and Diagnostics (AID) Tool is a device

that is a member of the Aurora network. The AID tool is used to

troubleshoot equipment which uses the Aurora control via Modbus

RTU communication. The AID tool provides diagnostics, fault

management, ECM setup, and system configuration capabilities to

the Aurora family.
