1. A refrigeration system, comprising:
an evaporator unit, comprising:
a housing configured to receive water and including an air inlet port configured to route air into the housing from ambient surroundings, and
a porous material disposed at a bottom portion of the housing for defining a first compartment and a second compartment within the housing, the first compartment configured to receive the water and the second compartment configured to receive the air through the air inlet port,
the porous material positioned above the air inlet port for allowing the air into the housing through the porous material, the air routed through the porous material dispersing within the housing to form air bubbles, the air bubbles inducing turbulent mixing between phase boundaries of water molecules and air molecules within the housing, wherein interfacial areas of the air bubbles and the turbulent mixing enhance evaporation rate of the water, thereby converting a portion of the water into water vapors leaving a remainder portion of water, wherein the water vapors on discharging from the housing cool the remainder portion of the water via evaporative cooling to form cooled water, and wherein the cooled water is settled on the porous material;
an evaporator outlet port physically coupled to a top portion of the housing, for discharging a mixture of the air and the water vapors from the housing;
a plurality of baffle plates mounted proximal to the evaporator outlet port for preventing splashing of the water during the turbulent mixing, the plurality of baffle plates mounted such that each baffle plate is mounted on an opposite side of the top portion of the housing, wherein one end of each baffle plate is physically coupled to the top portion of the housing and an other end is a free end disposed within the housing, such that, a path between the free ends may be provisioned;
a compressor unit physically coupled to the housing at the evaporator outlet port and configured to induce an evacuation action within the housing, the evacuation action enabling the air to enter the housing from the ambient surroundings via the air inlet port; and
a heat exchanger unit physically coupled to the housing and to an enclosure, the heat exchanger unit configured to refrigerate the enclosure; and
wherein the evaporator unit employs air bubble enhanced evaporation of water for maintaining required refrigeration.
