1、冷凍機組：通往各個房間的循環水由冷凍機組進行“內部熱交換”作用，使冷凍水降溫為5~7 ℃。并通過循環水系統向各個空調點提供外部熱交換源。內部熱交換產生的熱量，通過冷卻水系統在冷卻塔中向空氣中排放。內部熱交換系統是中央空調的“制冷源”。

2、冷凍水塔：用于為冷凍機組提供“冷卻水”。

3、“外部熱交換”系統：由兩個循環水系統組成：

⑴、冷凍水循環系統 由冷凍泵及冷凍管道組成。從冷凍機組流出的冷凍水由冷凍泵加壓送入冷凍水管道，在各個房間內進行熱交換，帶走房間內的熱量，使房間內的溫度下降。

⑵、冷卻水循環系統 由冷卻泵、冷卻水管道及冷卻塔組成。冷凍機組進行熱交換，使水溫冷卻的同時，必將釋放大量的熱量，該熱量被冷卻水吸收，使冷卻水溫度升高，冷卻泵將升了溫的冷卻水壓入水塔，使之在冷卻塔中與大氣進行熱交換，然后再將降了溫的冷卻水，送回到冷凍機組，如此不斷循環，帶走冷凍機組成釋放的熱量。

4、冷卻風機

⑴、室內風機：安裝于所有需要降溫的房間內，用于將由冷凍水冷卻了的冷空氣吹入房間，加速房間內的熱交換;

⑵、冷卻塔風機 用于降低冷卻塔中的水溫，加速將“回水”帶回的熱量散發到大氣中去。
