Power cuts are a big problem for ice-cream vendors too like any other small business.
Innovative solution to the problems of ice-cream vendors:-
The ‘solar freezers’ that are currently being used by ice-cream vendors are comparatively heavy,By night the solar freezers have to return to base-camp to be plugged in. The fluid that keeps the freezers at sub-zero temperatures (ideally minus15 degrees Celsius) is mixed with solar (hence the name) to prevent it from freezing and for reaching very low temperatures.
The temperatures of the freezer falls to minus 30 degrees Celsius by morning and it gradually rises during the day to above minus15 degrees Celsius, sometimes even higher than minus 14 degrees Celsius when the ice-cream begins to melt.
Each solar freezer consumes three to four units of power a day, says Mr. Ramu.
The Solar freezers, on the contrary, weigh 50 per cent less, are environment-friendly, do not consume any power and are truly mobile because they do not have to return to base camp to be plugged in. The biggest benefit is that power-cuts are of no consequence at all. The solar freezers are much safer when compared to the Glycol freezers, he says.
During day time the solar panels which provide shade from the harsh sun to the vendor and the freezer, generate enough power to cool the freezer and simultaneously charge a battery. The battery gives enough power to keep the freezer cool during the night.
Energy Efficient Refrigeration
Save on costs with SPS DC refrigerators and freezers. These high efficiency refrigerators and freezers have exceptionally low energy consumption requiring smaller, less expensive power systems and low operating expense. High quality construction provides excellent reliability and long life. Zero maintenance, brushless, thermostatically controlled DC compressor operates on 24 VDC.
SPS refrigerators and freezers provide outstanding economical and reliable operation. Low energy consumption is the key that allows SPS refrigerators and freezers to be cost effectively powered from solar & batteries. This technology allows refrigeration in remote locations where it was previously unavailable or prohibitively expensive.
