Energy saving and environmentally friendly atmospheric dehumidifier chiller for drinking purposes

Abstract

A method and machine to produce drinking water from fresh air using an energy saving and environmentally friendly chiller is comprising the following steps of: Filtering and sterilize fresh air, then passed to several evaporator coils to condensate the moisture and the condensate collected to a pan.Passing secondary condenser by cold air after passing evaporator coil and dipping tertiary condenser to a cold condensate water tank, so the refrigerant after the condenser will be subcooled and after passing through the expansion valve, will heat exchange with the brine as a secondary refrigerant in the heat exchanger.Where brine is passed to several evaporator coils in air handling unit to cool and condensate the moisture passing through the air handling unit, a part of the air will condensate and the other part will passed to a cooled room where the cold air of the room then will exhaust and used to cool the main condenser through the exhaust air duct.

Description

FIELD OF THE INVENTION [0001]This invention related to an energy saving and environmentally friendly atmospheric dehumidifier chiller for drinking purposes. Fresh air is passed to an air duct of an air handling unit which installed several evaporator coils to condensate the air to produce fresh water and cold air. Cold air and cold water are passed to the condensing coils separately to save the energy.BACKGROUND OF THE INVENTION [0002]Water shortage which have been suffered to many countries in the world is a crisis. Many countries in the world also suffer for drinking water. Usable water supplies have reduced by pollution contamination and sewage waste. Water treatment such as with chemicals as chlorine or other halogens, however the by-products of such treatment may be toxic and the result in further contamination. Treated municipal water supplies may be contaminated, with may lead to health problems in such drinking water.[0003]Various attempts have been made to overcome with a s...

AI Technical Summary

Benefits of technology

[0008]The main objective of this invention is to provide a machine which be able to produce drinking water by condensating the moisture of the humid air and saving the energy by handling the air as a cooling medium of the condenser.

[0016]The water production machine of this invention using brine as a cooling medium, is to save the refrigerant of the chiller and to ease a remote water treatment.

[0019]An energy saving chiller includes: main condenser which is cooled by the cooled room exhaust air, secondary condenser which is in series with the main condenser, is further cooled by the cold air after passing the evaporator coils in air handling unit, tertiary condenser which is in series with the secondary condenser, is dipped to a cold condensate water which is produced by the evaporator coils, and by cooling the three condensers, the refrigerant will be subcooled, so after expanded by the expansion valve to the heat exchanger, and after compressed by the compressor to the condenser, the work of the compressor is decrease due to the handling of the cooling medium of the condenser which will save the energy.

Problems solved by technology

Water shortage which have been suffered to many countries in the world is a crisis.

Many countries in the world also suffer for drinking water.

Water treatment such as with chemicals as chlorine or other halogens, however the by-products of such treatment may be toxic and the result in further contamination.

Treated municipal water supplies may be contaminated, with may lead to health problems in such drinking water.

But in this device there is no saving energy and the water produced is too cold and need a fan to produce fresh water.

There is no energy saving in this water generator device and this device just circulate the water to generate the drinking water which is cooled by evaporator coil.

This method only talk about energy saving by cooling stages and not for a cooler to generate the drinking water.
