The distributed energy station is a comprehensive energy facility which provides with electric power

steam

hot water

and air conditioner’s freezing water in a limited area by using heat-cool-electricity triple cogeneration technology

the advantages of its high efficiency and low pollution are more widely being emphasized. To determine the price of three products from the energy station of triple cogeneration

analysis method of algebraic mode in thermal economics is used. Taking the exergy flow as a valuating object

and introducing the principle of apportion according to the energy level

the cost equation as well as general analysis and computation model for acounting method in thermal economics have been established

and the distributed energy station being analysed and calculated. A comparison of the calculated result with that of traditional products' equavalent value method has been carried out

it is proved that the method of apportion according to energy level can be used as a foundamental basis to fix the price of heat

cool

and electricity.
