Guide : Dr. M. Elangovan


Large cold storage facilities for storage of vegetables are out of reach and unaffordable for the small and marginal farmers. The chiller is a cost effective and ultra-low energy consuming storage device and consists of three units –evaporative cooler, sub cooler and a food storage cabin. It uses Phase Change Material (PCM), which acts as an effective medium of passive cooling system, absorbing heat until it reaches its melting point and changes its phase from solid to liquid. The device consumes power only for charging the liquid PCM i.e. converting it back into solid state, which can be done during night times (off-peak) within 1-2 hours. Thus such food chillers can efficiently operate in regions of interrupted grid power supply as well.
