污水源与地下水源复合热泵空调系统设计与分析
Design and analysis of sewage and ground water source combined heat pump air conditioning systems
摘要：
针对中国石化齐鲁有限公司供排水厂的水源特点，对原有的空调及供暖系统进行了改造。夏季利用地下水作为水源热泵机组的冷却水，冬季利用该厂丰富的污水作为机组的吸热源。测试结果表明，室内温度达到设计要求，且在夏季空调面积增加的情况下，增加的设备投资可在两年内收回。

Abstract：
According to the characteristic of water source in China Petrochemical Qilu Limited Company Supplying and Discharging Water Factory, reforms the original air conditioning and heating system. Ground water is used as the cooling water source of heat pump units in summer; a great deal of production sewage is used as extracted heat sink for units in winter. Testing results show that indoor air temperature satisfies the design criteria, the increased equipment costs can be reclaimed within two years although there is an increase in air conditioning area.
