水泵变频能耗的试验研究

Constant Temperature & Constant Humidity Air Conditioning Unit Energy Saving Case Analysis and Exploration

对并联水泵采用变频调节及变流量调节多种组合方案,得出开式循环和闭式循环中水泵能耗的异同。结果表明,无论在开式和闭式循环中,采用变频调节相比变流量调节功率比小,更节能;在2个水泵并联时,采用同时变频调节方案最节能,且闭式循环比开式循环的节能效果明显;3个水泵并联时,闭式循环的最佳调节方案比开式循环的最佳调节方案节能10%。

Constant Temperature Constant Humidity air conditioning unit energy saving renovation case was introduced： recover condensation heat of refrigerant system to replace the most of electrical heat.The operation data of the before and after energy saving renovation was analyzed.The saving energy result in theory which is same as actual measurement.If only energy saving renovation scheme is reasonable such as replacing present electrical heat by recovering condensation heat of constant temperature constant humidity air conditioning unit,The rate of saving energy reach to 80%,renovation project can obtain a lot of benefits from partial renovation.
