【 Weak current College 】 how heat price?
Adopted in China for many years by building m2 hot prices, detrimental to mobilize for thermal and heating energy enthusiasm on both sides, does not comply with the requirements of the market economy and should be reformed. After the reform, urban heating of hot prices, should be determined by the capacity of heat price and measuring hot price two parts. According to the heat capacity of thermal users and is based on the construction, maintenance and management of investment funds calculation of thermal heat price-price is called the capacity; while the user's use of thermal and heating system operating cost of funds computing heat price, known as metering hot price. This is the hot price's "two-shift system".
The international heating and hot prices, are "double-system". This is because the city is the heat source for heating, heating and heat users an extensive, closed, complex system that is based on the various heat users maximum thermal load of the building. After the completion of the heating system, regardless of whether the user is using heat or heat, to be managed. Therefore, the heating system construction, maintenance and management of investment funds can only be paid by user to heat hot fee approach to recycling and added value. According to this calculation of heat price, i.e. the heat price for capacity. Heating system and heating to the user, you must consume a certain amount of fuel, electricity, water, and labor, heating enterprises therefore also invest some money. To this end, the heating enterprises should press the number of users using thermal heating charges levied for the recovery of the heat supply system of heating to the user and value-added investment funds. This portion of hot prices, i.e. to measure heat price. From here we can see that the capacity of heat price for fixed cost components, measuring the cost of heat price changes.
Some European countries for central heating of valuation approaches, often per unit of total heat loss buildings 50%-70%, with a heat meter count sharing, i.e. This section to measure heat price, the remaining 50%-30% of the price of the thermal capacity. Their reasons are: heating systems for construction and maintenance costs, must be shared by all users, even if some users are out of unwanted heat, the entire heating system is still running; and residential buildings of public building energy consumption costs can only be part of the household share; the household of the curtain walls, floor or room-temperature heat from each other, which should also be low users pay a fee to heat to the surrounding user as compensation. This approach is justified.
For China's future hot prices, fixed costs and changes in the costs in proportion to explore some of the city, being parsed and run according to the heating system and the information keeps on improving accumulation. But it is generally believed that in the early stages of transition to a market economy, the fixed costs of changes should be slightly larger than the costs, then as the market economy matures, gradually intensifying change costs as a proportion of the cost of the change is greater than the fixed costs in order to further encourage energy efficiency initiative.
