As a example of a residential district,analysis of the economical efficiency of different modes of district cooling systems is carried on in initial investment and operation cost in order to supply reference to the correct choosing of cold source of distrct cooling system.
For a thermal power plant with given capacity, in order to realize combined supply of heat, power and cold, determines the optimal cooling area of a district cooling system according to the feature of air conditioning load in central cooling district and the principle of minimal energy loss, thus fully exploits the advantages of the district cooling system and reduces energy consumption.
The application of regional cooling and heating system in residential district is in line with the urban planning of ″energy saving, environmental protection and comfort″ and the guide of energy sources policy and is of fine development prospect.
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.
Covers the benefits of ice storage, with some case stud ies shown as prime examples of the flexibility these systems offer to private and public entities alike and of the potential they hold for the years to come.
This paper discussed heating and cooling in Wuhan at present and pointed out its influences of the environment,raised that developing technology of regional heating and cooling,the environment could be protected.
