Analysis on Energy Saving Factors and research on Energy efficiency evaluation indexes of Ventilation and Air Conditioning System in the Underground Engineering

摘要

This paper makes comprehensive analysis on energy saving factors of ventilation and air conditioning system in the underground engineering mainly from five aspects, such as the overall scheme, cold - heat system, air system, water system and operation management. And based on this, furthermore, each energy saving factor is quantified, the energy efficiency evaluation indexes of each subsystem is studied. So that it provides a concrete and feasible evaluation index and its basic calculation method for energy-saving evaluation, diagnosis of energy saving and energy saving reconstruction work.
