A.1.4 Filter Dryer A Parker Liquid Line Filter Dryer was installed at the exit of the condenser. The filter was included with the Carrier outdoor unit. The model number was 163S. A.1.5 Mass Flow Meter The refrigerant mass flow rate was measured with coriolis type mass flow meters manufactured by Micro Motion, model number Elite CMF025. A.1.6 Compressor A Copeland scroll type compressor is used with this system. The compressor is located within the outdoor coil, as shown in Figure A.3. Copeland model # : ZP32K3E – PFV – 230 Copeland serial # : 98F721682 Initial charge: 4.02 kg R410A & POE oil Power source: 208/230V, single phase, 60Hz A.1.7 Expansion Valve The expansion valve for this system was supplied with the indoor unit. It is a short tube orifice type expansion device. The supplied description is: R410A AccuRater (Bypass Type) Model 70. A.1.8 Line Sets 9.5 mm o.d. copper tubing was used for the liquid line connection. 19 mm o.d. copper tubing was used for the suction line connection. All joints were brazed with silver solder. The length of both the liquid and suction line sets was 6.7 m. All exposed copper tubing was covered with 9.5 mm thick Armaflex pipe insulation. A.1.9 Sight Glasses Inline sight glasses were installed at the condenser exit and evaporator exit in order to be able to visibly check refrigerant conditions. These sight glasses were manufactured by Watsco Components, Inc. and are called Allin Liquid Eye Sight Glass. They are an off the shelf product. A.1.10 Charging Conditions The system was charged so that the outlet conditions from the indoor coil would match data supplied by the manufacturer for test conditions. At an outlet temperature of 30.3oC the refrigerant pressure was 2475 kPa. These outlet conditions existed for the dry coil test point where the indoor dry bulb temperature was 70oF and an outdoor dry bulb temperature was 47oF. A.2 R744 RAC1 System Components A.2.1 System Overview and Schematics of RAC1 A schematic of this system in heat pump mode can be seen in Figure A.4. A description of the RAC1 system in cooling mode is given by Beaver et. al (1999a). 52PDF Image | Comparison of R744 and R410A
