SOLAR LABORATORY REFRIGERATOR

WEIBER now introduces solar powered editions of refrigerators.

Solar Laboratory Refrigerator is one such application, using solar energy to convert to electrical energy to cool the refrigerator. Solar Lab Refrigerator is available in various sizes to meet our customer’s needs. We also customize refrigerators according to different requirement of capacity and ranges.

Solar power is the latest trend in technology to minimize the need of electrical energy generated. And even in rural and low lying areas where electricity does not reaches, the use of electrically operated refrigerators create a problem. A solution to such problem are solar refrigerators that get cooled through sunlight.

They use a combination of solar panels and lead batteries to store energy for cloudy days and at night in the absence of sunlight to keep their contents cool.

  1. Upright/cabinet type models available
  2. Alarm at faults: perfect alarm system that provide numerous audible/visual alarm functions in case of high or low temperature conditions, faults, door ajar.
  3. Robust powder coated steel cabinet: to provide strength, corrosion resistance durability and reliability.
  4. Microprocessor based controls(HMI+PLC optional)
  5. Stainless steel trays are provided for storage inside
  6. Fully hermetic domus compressor with integrated control electronics.
  7. Connect with DC power source directly e.g. solar power source.
  8. Connect with AC power source through an AC/DC adapter.
  9. Electronic fuse, automatic reverse voltage protection.
  10. LCD display for displaying temperature in oC and Fahrenheit: output of the refrigerator operations are in digital format(digits) thus giving you precise reading
  11. Anti-discharge protection for battery.
  12. Automatic turnoff when voltage is low.
  13. Strong lid, hinged with silicon and lockable: it gives complete access to the refrigerator in an easy manner, easily openable with less force and durability of silicon gasket is more which reduces temperature loss.
  14. Built in forcing ventilation system.
  15. Temperature recording.
  16. Circulation Fan with Variable Speed -
    • Electrical efficiency
      Variable speed motor saves money by reducing energy bills, as it consumes less electricity than conventional motor.
    • Cooling Efficiency
      Variable speed enables gaining air conditioning efficiency or SEER.
    • Air Quality
      Variable speed motor helps clean the air efficiently. When the fan is in constant operation (indicated by the "Fan" setting on thermostat), the motor continues to slowly circulate air, allowing filters to capture more contaminants.
    • Humidity Control
      Variable speed motor combined with a Thermostat allows controlling the amount of humidity.
    • Quieter Operation
      Variable speed blower motor are significantly quieter thanits single-speed counterpart.
  17. Air Cooled Refrigerated System - Air cooled refrigeration system offer various benefits like
    • low fan power consumption
    • resistant to corrosion and freezing conditions
    • requires very low maintenance
    • Guaranteed long life operation
  18. CFC free cooling-the air cooled refrigerators use refrigerants that are chlorofluorocarbon (CFCs) free, thus are ozone friendly and eco-friendly.

The solar panel converts sunlight into DC power or electricity to charge the battery. This electricity (charge) is controlled via a charge controller which ensures that battery is properly charged and not damaged. DC appliances can then be powered directly from the battery.


Method 1. Accessory: AC/DC adaptor.


The DC refrigerator can be powered by AC power (standard wall plug in a home or office). This allows the refrigerator to be powered using conventional wall outlets and the unit can work without solar panels, batteries or a charge controller. It is important to note that our units operate with as little as 60W.

Method 2. Accessory: solar panels, battery, charge controller.


The solar panel converts sunlight into DC power or electricity to charge the battery. This electricity (charge) is controlled via a charge controller which ensures that the battery is charged properly and not damaged. The solar refrigerator/freezer can then be powered directly from the battery.

Method3. Accessory: charge controller, solar panel, battery, AC/DC auto transfer switch, AC/DC adaptor.


This method combines method 1 and 2. By adding an AC/DC auto transfer switch, the refrigerator can operate using AC power. This is useful when the battery is discharged due to multiple rainy or cloudy days. When the battery can't provide needed electricity, the auto transfer switch can automatically switch to AC electricity (110V /220V). When the battery is recharged, the refrigerator will go back to DC solar power (12V/24 V).

Batteries

The battery most commonly used is the lead acid type, long life, deep cycle batteries are preferred. A capacity to run the refrigerator for five days without sun is recommended.

Charge regulator

The charge regulator maintains the power supply within the current and voltage range tolerated by the refrigerator and prevents overcharge of the battery. Some models include an audible alarm or warning light to signal when battery voltage becomes low

charge regulator solar laboratory refrigerator

AC/DC automatic switch

The automatic switch allows for power priority. If plugged into the DC port, the battery has priority. The system will operate using DC (battery power) and will only switch to AC power if the battery is exhausted. If plugged into the AC port, the system will operate using AC power and will switch to DC power (battery) only in the case of a power outage. The DC port is preferred as this does not cost any money to operate.

Construction details

WEIBER solar laboratory refrigerators have Outer body constructed out of thick PCRC, pre coated corrosion resistant GI sheet duly pre-treated with primers and rust proofing and paintedwith long lasting stove enamel or elegantly powder coated The inner construction is made of heavy gauge stainless steel sheet of SS-304 grade).
