Study on Saving Energy of a Glycol Heat Recovery System

Presented a method of saving energy-a glycol heat recovery system in air-conditioning system . Expounded the operation and energy-saving principles of the system . Analysed the economical characteristics in an engineering example. The results demonstrate that the glycol heat recovery system is not only operation cost saving but also no need to increase total initial investment of air-conditioning system . So the method has a broad application prospect in the field of air-conditioning energy saving.
