Low-GWP AREP SYSTEM DROP-IN TEST
1. Introduction:
This document reports the system drop-in test of R32 conducted on a 8 Ton VRF multi-split heat pump
designed for R410A (RXYQ96PBTJ / FXMQ12PVJU(2) + FXMQ18PVJU(4)) at Intertek (1809 10th St.
Suite 400, Plano, TX 75074). The baseline test of R410A was also conducted at Intertek with the same
testing units and facilities beforehand. The instrumentation and accuracies are shown on the page 19 and
20.
2. Details of Test Setup:
a. Description of System
The outdoor unit is RXYQ96PBTJ (SN: A000563) which uses an inverter-driven variable speed
and a fixed speed scroll-type compressors.
The indoor units are six of ducted fan coils, FXMQ12PVJU(2) (SN: E004602 and E004575) and
FXMQ18PVJU(4) (SN: E005852, E005714, E005715 and E005716). They use a DC fan motor
and direct drive sirocco fans.
The AHRI 1230 Directory ratings for this system are:
*1: “EER” is the system cooling efficiency and “COP” is the system heating efficiency.
b. Description of Modifications to System
The charge of R32 was optimized to 19.8 lb (8.98kg, 83.2% of R410A charge) to obtain the
maximum cooling efficiency (EER) at the standard rating cooling test conditions.
The components other than refrigerant in the system stay the same as R410A system.
c. Description of Tests Conducted
Both of the baseline R410A test and the alternative R32 test at Intertek follow AHRI 1230 and
ANSI/ASHRAE 37.

3. Results:
a. Data Form
Please see data forms of steady state test in the following pages.
The R32 properties come from Refprop 8 directly from NIST.
b. Conclusions
� R32 makes performance higher with 83% of R410A charge in case of using the existing
R410A system.
� R32 cooling capacity is 2.9% higher and EER is 6.4% higher than R410A at the standard
rating cooling conditions.
� R32 IEER is 9.5% higher than R410A. R32 part-load performance is even higher than
R410A.
� R32 high and low temperature heating capacities are 4.8% and 2.4% higher than R410A
respectively.
� R32 contributes to improvement in both capacity and EER/COP, but R32 discharge
temperature is higher than R410A as shown in Figure 5.
