西安地区不同能源形式分布式供冷的经济性分析

Economical Analysis of Different Distributed Cooling in Xi'an

计算在相同冷量下基于城市热网夏季供冷、电制冷、天然气型供冷三种分布式供冷模式的电价、热价、气价之间关系。提出了临界热价、临界电价、临界气价,从而得出了基于城市热网夏季供冷方式供冷成本的经济性。以某住宅小区为例,对居住区实行不同能源形式分布式供冷的经济性从初投资和运行费用两方面进行分析。研究表明在2014年西安市热价、气价、电价的基础上基于城市热网(标准热水)的供冷方式并不具备明显的经济效益。

Through the calculation and analysis on the same cold relations electricity prices, heat prices and gas prices, put forward the price of critical heat, critical electricity price, critical gas prices critical price to arrive at a cost-based cooling urban heating network in summer cooling mode economy. Through the calculation on the same amount of cold summer cooling based on city heating, electric refrigeration, and natural gas cooling type three distributed cooling mode of heat price, gas price, put forward the critical heat price, critical price, critical gas prices so that the economy of the city heating network based on cooling in summer for the cost of the cold. Taking a residential district as an example, it analyzes the economic investment and operation cost of different energy forms in residential area from two aspects. Studies have shown that on the basis of Xi＇an hot price, gas price, the price of 2014 based on urban heating network （standard hot water cooling approach does not have the obvious economic benefits）.
