Rheem SAVR-C VRF series comes with a wide operation range, which makes it suitable for all seasons. Tested up to 56°C ambient temperature by third party laboratories, it provides uninterrupted cooling at high ambient temperature.
New generation SAVR-C
VRF air conditioners
Unlike conventional AC system where if one component fails one customer suffers, in VRF if one component fails many customers suffer, hence in VRF technology, durability of components is of utmost importance. To provide the highest level of durability, Rheem VRF is equipped with components from renowned global brands. Durable parts make the system reliable in varying weather and load conditions ensuring uninterrupted cooling.
Features and benefits
Variable Evaporating Temperature technology enables system to run in three modes.
- Turbo Mode for Faster cooling,
- High efficiency mode for lower energy consumption.
- Alternatively, basic mode to balance between comfort and efficiency.
Rheem’s VRF works satisfactorily in scorching Gulf climate with outside temperature being as high as 56 ° C. This has been tested by reputed third party labs.
Specially designed condenser tubing routing ensures maximum sub cooling of liquid refrigerant, which is further cooled by Plate Heat Exchanger. Increased sub cooling improves cooling performance at high ambient temperature.
DC inverter compressor provides high-efficiency and large cooling capacity. It also enables stepless regulation of capacity.
- DC fan motor ensures stepless regulation of airflow volume.
- Dual EXV with by-pass valve confirms for stepless regulation of refrigerant flow.
- The system also comes with high precision pressure and temperature sensor.
These features provide precise room temperature control & increased reliability.
The refrigerant circuit design incorporates subcooling EXV which helps in eliminating the abnormal noise on the EXV of standby indoor units. This sub cooling EXV ensures that 100% liquid phase of the refrigerant flows through indoor EXV and not the mixture of gas and liquid.
RAPID COOLING/HEATING (HEAT PUMP)
This feature enables quicker pull down and increased comfort.
Long piping capability makes the system suitable for a variety of applications.
- Max. Total piping length: 1000m
- Max. Actual piping length: 240m
- Max. piping length from 1st indoor branch to the farthest indoor unit: 40m
- Max. Level difference between outdoor units: 5m
- Max. Level difference between indoor units: 30m
- Max. Level difference between ODU and IDU units: 110m
Auto Refrigerant Charging makes commissioning easier by ensuring precise amount of refrigerant charged in the system.
This function eliminates chances of human error & reduces commissioning time.
Self-diagnosis (Engineering Mode):
ODU engineering mode checks the operating state and shows the corresponding error code if the system is not functioning normally. This assists in easy commissioning and saves service time and cost.
Compression Ratio Control:
- Real-time monitoring the compression ratio
- The output of compressor and the EXV open degree can be regulated precisely to optimize the compression ratio
This increases compressor’s reliability in High ambient, saves service cost & provides uninterrupted cooling.
Auto dust removal function with reversible fan is useful in desert conditions, saving time and cost of service.
AUTO BACK UP
For a combined system: If one outdoor unit fails because of electrical faults, the system will provide uninterrupted cooling by automatically entering into back-up operation mode and will continue running for a certain time.
AUTO PUMP DOWN
In case of servicing requirement, refrigerant from piping and Indoor units can be pumped down to outdoor unit saving refrigerant cost and recommissioning time.
Rheem VRF is equipped with components from renowned global brands making the system reliable in varying weather and load conditions; ensuring uninterrupted cooling. Durable components further ensure cost efficiency and minimal maintenance.
Rheem VRF comes with refrigerant cooled electronic boards to ensure optimal working temperature for longer life and less maintenance.
Refrigerant cooling arrangement enables system to work at ambient temperature of up to 56°C.
CONTROLLERS
Rheem’s modern VRF system provides various control options integrated at multiple levels.
Touchscreen wired control for ducted indoor units control units individually or up to a group of 16 units in the same system.
CENTRAL CONTROLLER
Elegant looking touchscreen central controller controls up to 256 indoor units from multiple systems. Controlling multiple units as a group or individual offers great flexibility in cooling large spaces.
Central controller can take input from fire panel to SWITCH OFF the unit as required.
Centralized control software controls 4096 indoor units from 64 systems.
BUILDING MANAGEMENT SYSTEM: WITH MODBUS & BACNET CAPABILITY
Rheem VRF can be connected to third party BMS system through Modbus or Bacnet protocols.
Rheem provides solution to connect large numbers of VRF systems to Building Management System
TENANT BILLING SYSTEM
Proportional Power Distribution software distributes Electricity consumption bill to individual users based on usage. Tenant billing system makes Rheem VRF best suited for multi-tenant facilities.
WIFI CONTROL (APP) WITH OTHER CONTROLLERS
Rheem’s modern VRF system provides various control options integrated at multiple levels. One of the most convenient option is the Wi-Fi app that uses a unique cloud computing technology. You can control turning on and regulating the smart air conditioner remotely on your mobile device. You can also check the working condition and set weekly timing. The interface is simple and friendly, which is only designed for specific home-used smart air conditioners.
