This paper introduces two operational models in the ice storage air conditioning system, whichs are the water cooled chillers priority and the ice storage priority, the choice method of refrigeration unit, the computing method of the amount of water stored and the disposition of the ice storage system.

Design and development of an indirect evaporative water chiller;

Technical ways to Improve the energy efficiency of water chillers;

Optimization control strategy in air conditioning system with multi water chillers;

To solve the unstable operation of the water chiller unit, probes into the feasibility of fresh air cooling for a clean room and provides a design procedure verified with an example in Beijing.

In this paper,the influences of variable chilled water flowrate on the performance of water chiller unit were studied.

This paper analyses the energy consumption and running costs of two design options for sizing water chiller units, that is the asymmetric design option and the blended design option, and points out that the two options should be considered to optimize the design of airconditioning system while sizing water chiller units.

The World Chiller and Large AC Market in 2006(Part one);

Output distribution of a multiple chiller system under part load conditions;

Discussion and review on the models of vapour-compression heat pumps and chillers;

Choice of centrifugal water chilling unit in engineering design;

Combined with the practical program,it analyses the characters of different types of water chilling unit,in condition of partial load,the change of energy consumption of water chilling unit and pump,the optimum of the match of the large and small equipment,and mainly compares the merits and defaults of separate refrigerating station,first pump system and second pump system.

A software for fault diagnosis of water chilling unit is developed by applying fuzzy theory and artificial neural network in expert system.
