1. An AWG comprising an enclosure, an evaporator assembly, a condenser and a blower,
the enclosure comprising:
a bottom wall, sidewalls, top wall, at least one air inlet, and at least one air outlet, wherein
at least one enclosure air inlet is located at one of the sidewalls or top wall,
at least a portion of the bottom wall is elevated from the ground, and
the at least one enclosure air outlet is located at the elevated portion of the bottom wall;
the evaporator assembly comprising:
an air inlet pathway, an evaporator and an air outlet pathway, wherein:
the air inlet pathway is adapted to receive an airflow from the enclosure air inlet and direct the air flow to flow through the evaporator, the air outlet pathway adapted to receive the airflow from the evaporator and direct the airflow to the enclosure air outlet;
the enclosure accommodates the evaporator assembly, the blower is located at the enclosure air outlet or in proximity thereto, the blower and the condenser are located downstream of the evaporator assembly, the evaporator assembly is located downstream of the enclosure air-inlet, and
the AWG is configured to direct the airflow from the enclosure air inlet through the evaporator assembly, and down to exit through the enclosure air outlet at the bottom wall, and
further comprising a refrigeration cycle comprising:
an air filter located downstream of the enclosure air inlet and proximal to a heat exchanger evaporator, the heat exchanger evaporator is located downstream of the air filter, the evaporator comprising an evaporator air inlet and an evaporator air outlet,
a condenser located downstream of the evaporator, and the blower is located downstream of and parallel to the condenser,
such that, when the refrigeration cycle is operating, an air flow enters the air inlet, then through the air filter proximal to the evaporator, then through the evaporator air inlet to the evaporator where it is cooled to below its dew point and water is generated, then through the evaporator outlet to the condenser, then through the enclosure outlet and the blower.
