Abstract

The present invention relates to a high-efficiency air water system for a tropical climate, including a filtration system, in which an evaporator is provided in an internal accommodating space of a main body, and a condenser is installed in a perforated portion formed passing through a side wall of the main body, so that air cooled in the main body is used to dissipate heat generated in the condenser so as to improve dehumidification efficiency. The configuration of the high-efficiency air water system comprises: an air suctioning unit that suctions and supplies external air; a water generating unit that condenses moisture from the air supplied from the air suctioning unit to generate water; and a water purifying unit that filters and purifies the water generated by the water generating unit to a drinkable or usable state. The water generating unit is constituted by including a main body having an accommodating space provided therein, and an evaporator, a hopper, a water storing part, a condenser, and a compressor are installed in the main body.

Claims

1. A high-efficiency air water system for a tropical climate comprising:

an air suctioning unit (10) for suctioning and supplying external air, a water generating unit (20) for condensing moisture in the air supplied by the air suctioning unit (10) and generating water, and a water purifying unit (30) for filtering and purifying water generated by the water generating unit (20) so as to turn the water into drinkable and usable water,

the water generating unit (20) comprising;

a main body (21) having an accommodation space therein, an open upper side connecting with the air suctioning unit (10), and a perforated portion (21′

) formed at a lateral surface thereof;

an evaporator (25) horizontally installed at the upper side inside the main body (21) and cooling external air suctioned through the air suctioning unit (10′

) to a temperature equal to or below dew point;

a hopper (23) formed at the lower portion of the main body (21), supporting water generated by the evaporator (25), and having an outlet (23′

) on one side thereof so as to discharge water outwards;

a water storing part (24) installed at the lower side of the main body (21), and supplied with water discharged through the outlet (23′

) and collecting the same;

a condenser (26) vertically installed at the perforated portion (21′

) of the main body (21) and having a fan (26′

) formed at the outer surface thereof so as to discharge cool air in the main body (21) outwards by way of the condenser (26); and

a compressor (27) connecting with the evaporator (25) and the condenser (26) and compressing a circulating refrigerant,

wherein inlet and outlet refrigerant tubes of the evaporator (25) are provided with dual pressure switches (25A, 25B) that are turned off so as to obtain water by melting frost on a cooling pin of the evaporator (25) when pressure values measured by the pressure sensor (22) are not within a range of set pressure values,

the outlet (23′

) is provided with a U trap (40) so as to prevent a reduction in the amount of air introduced into the main body (21) while blocking air introduced through an outlet from the outside.

2. The high-efficiency air water system for a tropical climate according to claim 1,

Wherein the perforated portion (21′

) is provided with a plurality of blades (21″

) so as to prevent water, which falls while frost on the cooling pin of the evaporator (25) is melted, from being introduced into the condenser (26).

3. The high-efficiency air water system for a tropical climate according to claim 1,

Wherein the main body (21) is provided with a pressure sensor (22) installed on one side wall thereof so as to measure inner pressure and to control the operation of a freezing cycle.
