摘要

利用9－11°C的深層海水爲天然冷媒，能產生10－12°C的冷水，冷水接引至溫室內的冷風機後，可以吹送出19－20°C的冷風供降溫催花應用。夏季高溫的催花期間，能維持20坪（66 m^2）的雙層塑膠布溫室內日均溫爲21.9°C；日／夜溫爲23.9／20.0°C，可有效將溫室內溫度較室外降低10°C以上。在此催花環境下，Phal. Sogo Yukidian 'Ping Tung King'、Phal. Hwafeng Redjewel、Dtps. Sin-Yaun Golden Beauty 及Dtps. Queen Beer　‘滿天紅’等4品種之抽梗率可達100%，同時在催花後100天左右開花。經催花後之開花品質與高海拔對照區相似，甚至較轄內平地催花冷房之催花效果更佳。深層海水冷源溫室夏季催花所需電費爲13.3元／株，與上山催花的代工費相較節省了一半，與平地催花的冷房用電相比更是節省了將近80%。

Use of 9-11℃ deep ocean water (D.O.W.) as a natural refrigerant through high-efficiency plate heat exchanger could produce 10-12℃ cool water, this cool water was piped to the air blower in D.O.W. cooling house and blowing 19-20℃ cool wind for flower forcing of Phalaenopsis. During the hot summer season, this system could maintain average daily temperature and day/night temperature at 21.9℃ and 23.9/20.0℃ respectively in 66 m^2 double plastic film greenhouse, that could be lower almost 10℃ than the outdoor temperature. Cultivars of Phal. Sogo Yukidian 'Ping Tung King', Phal. Hwafeng Redjewel, Dtps. Sin-Yaun Golden Beauty and Dtps. Queen Beer 'Red Sky' were 100 % be forced to bloom after forcing in D.O.W. cooling house. These 4 cultivars took about 100 days to bloom after forcing, the flowering quality of them was similar to the forcing greenhouse at high altitude and even better than air-conditioned cooling house at low altitude in Hualien county. The electric cost of Phalaenopsis flower forcing in D.O.W. cooling house was 13.3 NTD/pot, that was only half the cost of flower forcing at high altitude and was saved almost 80% cost of flower forcing at the air-conditioned cooling house.
