Calculation and analysis on energy consumption coefficient of cold source of air conditioning under partial load;

Application Prospect s Analysis About Ammonia as a Refrigerant in Cold Sources of Air-conditioning System;

Ammonia as a refrigerant is excellent, if we can use it very safely, ammonia will be an alternative refrigerant in air-conditioning system.

Comprehensive analysis and comparison of air conditioning heat/cold sources of electricity heat and chilled water congenerating system;

In accordance with 5 schemes of air conditioning heat/cold sources,the most optimised option is obtained by gray matter element analysis from their initial investments,annual operating costs,safety,environment effects,technology and operating management.

Establishes a grey matter element analysis model and makes a quantitative assessment of three typical options of air conditioning heat/cold sources based on their initial investments, annual operating costs, safety, environment effects, technology and operating management, and obtains an optimised option, which agrees with that in practice.

Selection of optimal scheme about air conditioning cold/heat source;

Thus,a new method for designers of HVAC to compare was offered and different air conditioning cold/heat sources were evaluated.

The uncertained and fuzzy factors can be quantified by this way, which settles the disadvantage and difficulties in the traditional methods, and makes it more scientific to select the air conditioning heat/cool source system.
