The current central heating systems using heat meter or other measuring instruments + valve + temperature control valve of household metering adjustment programmes while investing significantly, but would not necessarily be able to truly meet users adjust to the ambient personalization needs. Mainly because my existing heating system design capacity is low, it is necessary to further improve the heating temperature is quite difficult, you must expand the community network for at least 10% to 20% in order to ensure that users can access more than design room temperature 1 ° c to 2 ° c increase of the space, but this is still too small room for upward adjustment; if you want to ensure that batch heating room temperature comfort is to expand the community network for at least 25%.
Addition of thanks to our 18 ° c room temperature heating has been lower standard, comfort, so the significance of the temperature dropped. To adjust the room temperature personalized visible actually bring comfort upgrade is not obvious, while energy-saving effect is also very small. Only users in the long time out of closed heating equipment with relatively small energy saving effect.
Current heating metering in pilot or implementation process are experiencing great difficulty was unexpected is reasonable. So called because they are part of most people think that foreign already very mature of heat meter technology and other sophisticated metering technology copying to my country should have no problem, but in practice it is extremely difficult, since applications environment changed dramatically, from the heating industry, technology, management and financial capacities to the level of the national economy, the people's way of life, energy saving consciousness, personal qualities, legal environment, have changed dramatically, so rought is reasonable.
Europeans have their own characteristics come up with a heat meter, heat distribution tables, solve their problems; we heating metering should learn their down-to-Earth research itself features to create truly suited for heating metering solutions, so they really understand the "borrowed" the true meaning.
According to the heating area billing scenarios have been used in China for many years, very mature, this billing mode the heating sector assumes the duties of the heat supply and assume the responsibilities of room temperature control, which ensures users always not lower than room temperature of 18 ° c, in fact the user access to services is a "guarantee" and "room temperature heating time guarantee".
Traditional press heating area billing programmes advantages are: 1. adopt guarantee user room temperature heating mode, reduces user heating equipment automation, does not need to install the temperature control system; 2, on the user's requirements is lower, even if the user does not have knowledge of the basic regulation or in the comfort and energy saving effect to get the best balance between; 3, conducive to saving energy, heating sector only meet basic comfort room temperature heat, will not cause the room temperature is too high and energy waste, and, of course, like the warmer room temperature of users still can use electric heaters and other heat sources gets higher room temperature and conform to the principles of energy utilization in Echelon; 4, heating charges are not directly linked with the heat, so that enterprises operating pressure is reduced, and our most heating enterprise management level lower status. Because of these characteristics and in most parts of the real economy, technology, energy supply, and so on, so it can become a widespread application in the form of heating.
Since the heating area billing has many irreplaceable advantage, and with China's national conditions sufficient adaptability, so we should make full use of this advantage, not all negative, completely Europeanized, start over, which does not conform to create objects of the society.
In depth analysis by heating area billing mode you can find the "guarantee heating room temperature" and "ensure the heating time" is an existing press heating area billing mode of two elements, in both of these elements determine the basis to develop the heating area billing mode of heat price per square meter. Existing billing mode according to the heating area is not able to achieve by meter, mainly because of the "heating heating temperature" and "time" are fixed, so the user is also a hot fixed costs. "Heating heating temperature" and "time" is determined by the people, in addition to the prevailing social factors, technical factors is another major reason was because electronic industrial technology behind not enough low cost manufacturing suitable for home use of set temperature, time measurement and data storage functions of micro-devices.
