New cold regulation method of district cooling systems;

Optimal design for tree-shaped chilled water pipe network in district cooling systems;

Research on quantitative control strategy of district cooling systems;

According to the principle of minimizing the life cycle cost of chiller systems,this paper proposes an optimal model considering the variation of all-year cooling load to distribute the design capacity among different types of chillers in the district cooling system.

Considers that in the future residential air conditioning in large cities should be directed toward district heating/cooling and cogeneration of heating/cooling and power while in middle and small cities or suburb areas,the so called household air conditioning should be promoted and for apartments for singles or shared occupancy,the room air conditioners are desirable, and that these ways a.

Application of central cooling system to Guangzhou Metro Line 2;

Based on the energy consumption model, the effect of running parameters on the energy consumption of the residential central cooling system was analyzed, a new term called system coefficient of performance (SCOP) was put forward, and an optimal model was established to get the maximum SCOP during the running of the system.

Taking the regional cooling and heating system of a residential area for example,a technical and economic comparison on four kinds of schemes for the system is made by using calculation methods of life cycle cost and cost recovery period.
