Abstract
The consumption of cooling and heating energy and the methods of heating and cooling used in large public buildings are analyzed in this paper. A comparison between initial investment and operation costs of heat pump and traditional heating modes used in large public buildings is also introduced. A life cycle cost (LCC) mathematical model is established to analyze the main factors that affect the LCC including the advantages and disadvantages of heat pumps currently in use. Some suggestions about heating and cooling modes applied in large buildings in different geographical areas are given in this paper.
Highlights
With the increasing urban environmental requirements, energy supply structures are gradually changing
The life cycle cost (LCC) mathematical model is a mixed planning problem by 0 - 1 [22], it sums up the cooling and heating system optimization question as different areas, different cold and heat source, different energy price, different equipment investment, and the same cooling or heating amount, as the constraint condition of optimal allocation question. the dynamic technological methodology of economic evaluation, time and value factors of fund are considered, aimed at the minimum LCC discount, calculate combine the constraint condition
By considering the different origins and energy price difference caused by the current transport several domestic large public buildings heating cooling, these conclusion can be arrived: 1) For large public buildings, several heating and cooling ways that applied mainly at present carrying on the analysis of life cycle cost, through different area, different climate and the energy price difference caused by producing area and transportation; 2) It considers the influence of all kinds of energy prices and the difference caused by the production and transport caused by different forms of cooling
Summary
With the increasing urban environmental requirements, energy supply structures are gradually changing. To make cooling and heating technology and economic indicators which optimized for large public buildings life cycle cost (LCC) and value engineering principles are discussed in this article. Transport aspects and price of energy into consideration in different regions and climate conditions, an analysis of life cycle costs of several modes of heating and cooling, heat pump heating and cooling, coal-fired boiler + water chilling unit, gas fired boiler + water chilling unit, oil fired boiler + water chilling unit, currently used in large public buildings is considered. Several heating and cooling modes heat pump heating and cooling, coal-fired boiler + water chilling unit, gas fired boiler + water chilling unit, oil fired boiler + water chilling unit in large domestic public buildings are conducted by considering the energy price differences of climatic regions, location of production and transportation costs. Suggested engineering practice guidance to further promote the development of district heating and cooling is provided
