Most of the electrical energy used by an industrial air compressor is converted into heat and has to be conducted outwards. In many cases, a properly designed heat recovery unit can recover a high percentage of this available thermal energy and put to useful work heating either air or water when there is a demand.

工業用的空氣壓縮機所使用的電力大部分都轉變成為熱能而備導出到外界。有些情況下，適當的熱回收的設計可以回收很高比例的可用熱能，做為有效的工作熱源加以利用，例如加熱空氣或水。

Heat recovery systems are available for most compressors on the market as optional equipment, either integrated in the compressor package or as an external solution. An existing CAS can generally be retrofitted very easily and economically. Heat recovery systems are applicable for both air- and water-cooled compressors.

熱回收系統是大多數市場上採用的壓縮機的選用裝備，可以整合至壓縮機中成為一套裝設備,:也可以當作是系統外加，熱回收系統可以應用在氣冷式及水冷式的壓縮機上，使用中的空氣壓縮機系統可以很容易而且很經濟的加以改裝。

As much as 80 - 95 % of the electrical energy used by an industrial air compressor is converted into thermal energy. In many cases, a properly designed heat recovery unit can recover approximately 50 - 90 % of this available thermal energy and put it into useful work heating air or water.
The potential energy savings are de pendent on the compressed air system, on the operating conditions and on the utilisation.
Recoverable heat from a compressed air system is normally insufficient to be used to produce steam directly.
Typical air temperatures of 25 to 40 °C above the cooling air inlet temperature and water temperatures of 50 to 75 °C can be obtained.

工業用空氣壓縮機使用的電能有80~95%轉變為熱能。經過良好設計的熱回收單元可以回收大約50~90%的可用熱能，將之用於工作空氣或水的加熱上。潛在的節能效果要看空氣壓縮機系統、作業條件及用途而定。從空氣壓縮機系統回收的熱能通常都不夠直接使用在蒸氣生產上。通常加熱後空氣的溫度是在冷卻器進氣溫度的25~40°C之上，加熱後水溫則約為50~75°C。
