RFVB SOLAR POWERED VACCINE STORAGE REFRIGERATOR FREEZER
- MOST EFFICIENT REFRIGERATOR IN ITS SIZE RANGE
- LOWEST SYSTEM COST: FEWER SOLAR PANELS AND BATTERIES TO PURCHASE, TRANSPORT, AND INSTALL
- RUGGED CONSTRUCTION FOR REMOTE SERVICE
- RELIABLE: ONLY ONE MOVING PART
- EXCELLENT TEMPERATURE CONTROL
- RESERVE COOLING CAPACITY: RUNS ONLY 27% OF THE TIME IN A HOT 43C (110F) ENVIRONMENT
- EASY TO DEFROST AND CLEAN: MORE CONVENIENT THAN CHEST MODELS
- TESTED AND APPROVED BY THE WORLD HEALTH ORGANIZATION FOR VACCINE STORAGE
RELIABLE: MANY YEARS OF TROUBLE FREE OPERATION
The sole moving part in the BALAJI RFVB refrigerator is a hermetically sealed compressor. The brushless motor used in the DC models eliminates periodic servicing. If servicing is ever necessary, the simplicity of the cooling system and the accessibility of the compressor make it a simple matter.
Life expectancy of a compressor is lowered primarily by high condenser and oil temperatures. The BALAJI refrigerator, with its top mounted cooling system, allows room for air to freely circulate and effectively cool the compressor and oversized condenser. Conventional cooling systems, mounted in confined spaces on the side or below the refrigerator, will run considerably hotter, lowering compressor life.
The evaporator in the RFVB is protected by a fiberglass liner and cannot be punctured while defrosting, a common problem in many manual defrost refrigerators.
Also contributing to the longevity of the cooling system is the Compressor's low percentage run time, only 19% in a 32C (90F) room. The low energy consumption of the RFVB allows the use of a smaller and more reliable battery for the funds expended. In a photovoltaic refrigerator system, the battery bank is the component with the shortest expected life. A battery may last from 2 to 15 years, depending on the quality of the battery and how it is used and maintained. Decreasing the degree to which the batteries are discharged extends Battery life.
NO FOSSIL FUELS
The BALAJI RFVB provides a means of storing vaccines and medical supplies without the use of fossil fuels. Not only is the need for a fuel supply eliminated, but the unit operates more reliably than kerosene powered refrigerators. The refrigerator is typically powered by a photovoltaic-charged battery bank. This reliable power source is dependent only on sunlight, which is in abundance in most developing nations. Alternatively, the system's batteries may also be charged by wind, hydropower, or a small generator. If portability is important, car or truck batteries may run the refrigerator. In areas where utility power is intermittent but where it is important to maintain reliable refrigeration, the system's batteries may be powered by a small battery charger powered by utility power.
RFVB: THE MOST EFFICIENT REFRIGERATOR
The BALAJI RFVB refrigerator employs unique design innovations to achieve its exceptionally low energy consumption. The heart of the system is a highly efficient compressor and condenser. Top mounting the cooling system lowers the energy consumption in two ways: (1) heat gain into the cabinet is reduced and (2) the lower condenser temperature increases the efficiency of the cooling system.
The walls of the RFVB contain four to six inches of polyurethane foam insulation - the best insulation commercially available. Unlike many other refrigerators, the insulating value of the walls of the RFVB are not lowered by metal supports between the inner and outer cases.
The top mounted condenser on the BALAJI RFVB is accessible and easy to clean, allowing the cooling system to continue running efficiently. The efficiency of the cooling system is further increased by eliminating the need for fans, which consume energy and generate unwanted heat and noise. Furthermore, dust and cobwebs which collect on the intricate surface of the back or bottom mounted condenser of conventional refrigerators reduce the effectiveness of their cooling systems.
Energy Consumption Balaji RFVB Typical Domestic Refrigerator
EFFICIENCY REDUCES SYSTEM COSTS TO LOWEST AVAILABLE
When making ice the highly efficient BALAJI RFVB typically saves 25 amp hours per day when compared to the average refrigerator tested by the World Health Organization. This increased efficiency translates to a savings of over $1,000.00 in the PV power system.
ICE STORAGE FURTHER INCREASES SYSTEM RELIABILITY
The relatively large freezer in the RFVB can easily hold 12 kilograms of ice.
This ice may be transferred to the refrigerator section if the cooling system is
not in operation due to refrigerator failure, loss of power, or an exceptionally long overcast period. The 12 kilograms of ice now stored in the super-insulated refrigerator section will keep the stored vaccines cold for approximately nine days. If the system's batteries are low because of extremely bad weather, this nine day period should be sufficient to let the batteries recharge. Without ice storage, it would be necessary to purchase additional batteries to maintain the vaccines during prolonged overcast conditions.
* One amp hour is equivalent to 12 watt hours.
DEFROSTING: A SIMPLE MATTER
When defrosting is needed, it is fast and easy. Just turn off the refrigerator for about 30 minutes. Since ice forms only on the flat, easily cleaned surfaces, it comes off in large pieces. There are no irregular shapes and ducts to grip and hold the ice, and no water to mop up.
RFVB EFFICIENT COOLING SYSTEM
The temperature of the refrigerator section is tightly controlled for vaccine storage. The large capacity freezer section can produce 2 kilograms of ice per day in a 43C (110F) environment running only 42% of the time. Ice is produced very efficiently in the RFVB; only 6 amp hours are typically consumed to produce one kilogram of ice. Competing models use nearly twice as much energy for ice production.
The evaporator design contributes significantly to the efficiency of ice production. Containers being frozen make direct contact with the evaporator molded into the floor of the freezer section. A second evaporator in the ceiling of the freezer effectively cools the contents of the freezer by convection.
In a chest type freezer, it is difficult to make direct contact with the evaporator for effective conductive cooling. Also, in a chest type freezer convection is less effective because the evaporator cannot be mounted above the freezer. The freezer section of the RFVB is isolated from the refrigerator compartment by three inches of polyurethane insulation. This feature prevents stored vaccines from being heated when warm water is placed in the freezer, a problem in refrigerators of conventional design.
In addition to efficiency, the RFVB design offers convenience. Stored vaccines are much more accessible than they are in chest models. Health workers generally find the vertical design much more acceptable.
