齐鲁塑料厂中央空调由原来的中压蒸汽通过换热器加热脱盐水作为热媒供热，改造后主要用苯乙烯工艺凝液通过换热器预热脱盐水，然后用中压蒸汽换热器调整脱盐水到合适的温度后供热。达到利用工艺凝液的余热，节省中压蒸汽的目的。

The central air conditioner in Plastics Complex supplied heat with desalinated water as heat medium which was heated by medium - pressure steam through a exchanger. After revamp, condensed liquid in styrene process is mainly used to preheat desalinated water through heat exchanger, and then heat exchanger for medium - pressure steam is used to adjust the temperature of desalinated water. This method is steam saving by means of waste heat utilization.
