The Amount of Fresh Water Wasted as by Product of Air Conditioning Systems: Case Study in the Kingdom of Bahrain

Millions of air conditioning units consume about 60-64 % of total produced electrical energy in GCC Countries in the summer season. Conditioning the air involves taking the heat out and also extracts moisture (humidity) out of the air. This dehumidification process utilizing the evaporator of air conditioning units could be an alternative and sufficient means to obtain fresh distilled water. There is a strong potential for condensate collection technology to impact water shortages in the regions of the world where suitable conditions exist.This paper presents case study analysis of experimental investigation and practical application of the amount of condensed fresh water can be collected and utilized from the discharge pipe of a two tones of refrigeration indoor air conditioning unit installed in a house during the summer season in the Kingdom of Bahrain. Up to 7 liters/hour of freshwater was obtained with an overall average rate of 2.07 Liters/hour. The study gives a good prediction of the amount of condensed fresh water output for particular indoor relative humidity.
