The drinking water supply system applicable to the laying hen consists of air-water heat pumps, drinking water tanks, heat stroage tank, circulation pumps, PE pipes, nipples, and control panels. When the heat pump system has power of 7.7 to 8.7 kW per hour, the performance coefficient is between 3.1 and 3.5. The supply temperature from the heat pump to the heat stroage tank was stabilized at about 12±1°C, but the return temperature showed a variation of from 8 to 14°C. Stratified temperature in the storage tank appeared at 12.°C, 13.5°C and 14.4°C, respectively. The drinking water supply temperature remained set at 15°C and 25°C, and the conventional tap water showed a variation for 23°C to 30°C. As chickens grow older, the amount of food intake and drinking water increased. y = -0.0563x2 + 4.7383x + 8.743, R2 = 0.98 and the feed intake showed y = -0.1013x2 + 8.5611x. In the future, further studies will need to figure out the cooling effect on heat stress of livestock.
