How It Works

The EcoNet® Enabled, Inverter Driven Rheem® Prestige® Series Variable Speed Heat Pump’s ( 5 ) variable speed outdoor unit control (VSODU) ( 6 ) continuously monitors the EcoNet control temperature and humidity set point, suction pressure ( 7 ), suction temperature ( 8 ), outdoor coil temperature ( 9 ) and outdoor temperature ( 10 ) and feeds this information to the Copeland Inverter Control Motor Drive ( 11 ). The Copeland Inverter Control Motor Drive converts AC to DC power, sends it to the Copeland Scroll™ variable speed compressor ( 12 ) Brushless Permanent Magnet motor (BPM), dynamically adjusting its speed. Simultaneously the VSODU provides input to the ECM outdoor fan motor ( 13 ) which is equipped with the latest

swept wing fan technology ( 14 ) and the Electronic Expansion Valve (EEV) ( 15 ) which syncs up with the compressor speed to deliver the exact capacity the home needs to meet its comfort requirements. The result of this advanced technology is significantly improved energy efficiency and comfort. Energy efficiency is improved by precise load matching, less cycling on and off and low amp gradual compressor, outdoor and indoor motor operation. Comfort is improved by precise temperature control, precise humidity control and extra capacity during extreme summer and cold weather conditions.

System Component Descriptions

EcoNet Control Center – ( 1 ): The EcoNet Control Center serves as the hub of communication for a home’s Heating, Cooling and Water Heating systems and is required to operate an EcoNet Enabled Heating and Cooling system in a fully communicating mode. The EcoNet Control center displays detail diagnostic from outdoor and indoor connected units. See individual specification documents for more details of the EcoNet Control Center.

EcoNet Cooling and Heating WiFi Module – ( 2 ) is required to remotely operate an EcoNet Enabled Heating and Cooling system from the EcoNet web portal and mobile apps. See individual specification documents for more details of the EcoNet Control Center.

Variable Speed Outdoor Unit Control (VSODU) – ( 6 ) is where control wiring is hooked to the RP20. The VSODU control takes input from the EcoNet Control Center, outdoor suction temperature and pressure sensors, outdoor air and coil temperatures and communicates to the Copeland Inverter Control Motor Drive, EEV, reversing valve, outdoor fan and indoor blower to precisely control system capacity output of the heat pump in heating and cooling modes. It also is equipped with Dual Seven-Segment Display for technician interface, operation status and fault code communication. Two momentary buttons allow technician to initiate various operating modes. Various LED’s communicate active EcoNet communication, microprocessor activity and EEV operation. See I&O for more details.

The Copeland Inverter Control Motor Drive – ( 11 ) converts incoming single-phase AC power to 3 phase DC simulated sine wave power. Once power is converted the Copeland Inverter Control Motor Drive varies frequency of the power to the compressor varying the compressor speed. The Copeland Inverter Control Motor Drive has active protection algorithms that keep the compressor safely inside its operating envelope.

The Copeland Scroll™ Variable Speed compressor – ( 12 ) utilizes a Brushless Permanent Magnet Motor (BPM) that varies the Scroll speed, thus, varying the refrigerant flow. The robust scroll design has proven reliability over competing compressor technologies.

Swept Wing Fan Blade – ( 14 ) is the latest technology in outdoor fans that increase efficiency and reduces air noise.

The Electronic Expansion Valve (EEV) – ( 15 ) is an electronically driven refrigerant control valve. A small stepper motor is used to open and close valve to precisely control refrigerant flow. It is controlled by the VSODU, which receives input from the pressure transducer and suction line temperature sensor to control the RP20 in the heating mode. The VSODU drives it fully open in the cooling mode. The EEV is superior to a TXV (thermostatic expansion valve) because the EEV controls superheat at the evaporator coil under varying load and refrigerant flow conditions, more precisely than traditional TXV’s.

The Filter – ( 16 ) is an electrical device that “cleans” the AC power component. This low pass filter only permits the passage of 60-Hertz signal to the inverter drive.

The Pressure Transducer – ( 7 ) is used to measure suction pressure in the outdoor heat pump. The VSODU takes this input to operate the EEV and make decisions on system operation such as low ambient cooling.

Various temperature sensors – are located on the Heat Pump. There is an outdoor air sensor ( 10 ), an outdoor coil sensor ( 9 ), a discharge line temperature sensor (not shown, located on discharge line), a suction line temperature sensor ( 8 ) and a compressor sump temperature sensor (not shown, located bottom of compressor). The VSODU uses these temperature measurements to operate the system.

The Choke – ( 17 ) is provided to absorb power spikes that might occur on the DC line.

Ferrite Rings – ( 18 ) are iron cores through which AC power is looped keeping any electrical noise contained. They also reduce the induction of electrical transient into the DC drive.

The Suction Accumulator – ( 19 ) prevents liquid refrigerant from entering the compressor.

The Reversing Valve – ( 20 ) reverses the flow of refrigerant in cooling versus heating.

Features

In addition all RP20 Prestige Series Inverter Driven Variable Speed Heat Pumps have the following features:

Our unique composite base ( 3 ) reduces sound emission, eliminates rattles, significantly reduces fasteners, eliminates corrosion and has integrated brass compressor attachment inserts ( 4 ).

Furthermore it has incorporated into the design, water management features, means for hand placement ( 5 ) for unit maneuvering, screw trays ( 6 ) and inserts for lifting off unit pad. ( 7 )

Service Valves ( 8 ) are rigidly mounted in the composite base with 3" between suction and discharge valves, 4" clearance below service valves and a minimum of 5" above the service valves, creating industry leading ease of installation. The minimum

27 square-inches around the service valves allows ample room to remove service valve schrader prior to brazing, plenty of clearance for easy brazing of the suction and discharge lines to service valve outlets, easy access and hookup of low loss refrigerant gauges ( 9 ), and access to the service valve caps for opening.

Controls are accessed from the corner of the unit by removing only one fastener from the control access cover, revealing the industry’s largest 15" wide and 22" tall control area ( 10 ). With all this room in the control area the high voltage electrical whip ( 11 )

can easily be inserted through the right size opening in the bottom of the control area. Routing it leads directly to lugs for connection. The low voltage control wires ( 12 ) are easily connected to the units VSODU terminal strip. The service window

( 14 ) can be removed by removing two screws, to access the EEV

and view interior of unit. ( 15 ) (High and low pressure is standard on RP20 models).

If in the rare event, greater access is needed to internal components, such as the compressor, the entire corner of the unit can be removed along with the top cover assembly to have unprecedented access to interior of the unit ( 16 ). Extra wire length is incorporated into each outdoor fan and compressor so top cover and control panel can be positioned next to the unit. Or with minimal effort the plug can be removed from the compressor and the outdoor fan wires can be removed from the VSODU to allow even more uncluttered access to the interior of the unit

( 17 ). Outdoor coil heights range from as short as 35" to 48". Disassembly to this degree and complete reassembly only takes a first time service technician less than 10 minutes. ( 17 )

All units utilize formed louver panels which provide industry leading coil

protection. Louver removal for coil 19 cleaning is accomplished by removing

one screw and lifting the panel out of the composite base pan. ( 19 ) All RP20 units utilize single row coils ( 18 ) making cleaning easy and complete, restoring the performance of the air conditioner back to out of the box performance levels year after year.

The outdoor fan motor has sleeve bearings and is inherently protected. The motor is totally enclosed for maximum protection from weather, dust and corrosion. ( 20 ) Access to the outdoor fan is made by removing four fasteners from the fan grille. The outdoor fan can be removed from the fan grille by removing 4 fasteners in the rare case outdoor fan motor fails.

Each cabinet has optimized composite ( 21 ) fan orifice assuring efficient and quiet airflow.

The entire cabinet has post powder paint ( 22 ) achieving 1000 hour salt spray rating, allowing the cabinet to retain its aesthetics throughout its life.

The Copeland Scroll™ Variable Speed compressors ( 28 ) with standard internal pressure relief and internal thermal overload are used on all capacities assuring longevity of high efficient and quiet operation for the life of the product. All RP20 Heat Pump come standard with high and low pressure switches reinforced vinyl compressor sound covers containing a 11/2 inch thick batt of fiberglass insulation and open edges are sealed with a 1 inch wide hook and loop fastening tape for superior sound quality.
