Analysis of five major problems in current heating management

With the development of society and the continuous improvement of people's living standards, traditional heating methods and management models have become less and less suitable for the development of the times. Therefore, how to actively and steadily promote heating reform has become our top priority. This article makes a preliminary study on some related issues in heat supply management, the main contents are as follows:

　　Intensify heating reform

　　 Under the traditional heating system, most of them are welfare heating, and the heat users only pay a small part of the heating fee symbolically. However, the decentralized small boiler heating mode of various units wastes resources, is low in efficiency, and pollutes the environment, and can no longer meet the development requirements of the era of "energy saving and emission reduction". In line with the work policy of "energy saving and environmental protection", decentralized small boilers should be gradually banned, and centralized heating should be actively promoted. In this way, the heat users are pushed to the market, and the heating unit assumes the heating task.

　　Clarify the scope of management and responsibility

　　 When the heat supply and use parties sign the heat supply and use agreement, they generally clarify the property rights demarcation point of the two parties (mostly the stairway entrance valve well is the boundary) and the management scope. However, in the actual operation process, as long as some users fail to meet the heating standards, they will push the responsibility to the heating unit, such as obsolete radiators, small numbers, poor pipelines or even blockages, and even push the responsibility to development. Business, this will cause unnecessary troubles and disputes.

　　 Vigorously promote the factors affecting heating

　　 Whether the indoor temperature meets the standard depends largely on the heating quality of the heating unit, but it also has a lot to do with the heat users themselves. For example, whether the heat dissipation effect of the radiator is good or not, whether the number of radiators matches the heating area, whether the heating system is reasonable, whether the enclosure structure and sealing are good, whether the pipeline system is cleaned, whether the indoor pipeline is modified, whether the water is discharged without permission, Whether to install a pipe heat exchanger, etc.

　　 It is difficult for users to realize all of the above problems, and it is difficult for them to deal with all of them. Therefore, indoor temperature standards should restrict both heat supply and use. Only when the heating quality of the heating unit meets the standard, and the thermal facilities of the heat user also meets the standard, and then measured by the temperature standard, will it have a broader practical significance. The following summarizes the factors affecting heat supply from the thermal user side:

　　 (1) The plane shape and orientation of the building, the thermal insulation performance of the envelope structure, and the thermal insulation and sealing conditions of external doors and windows will cause large differences in the heating effect, and even cause the indoor temperature in some areas to fail to meet the standard. Compared with traditional buildings, energy-saving buildings have greatly reduced area heat consumption indicators, with an average difference of about 20 W/m2. It can be seen that building conditions will have a greater impact on heating effects;

　　 (2) The different heating modes of thermal users have a greater impact on the heating effect. Low-temperature floor radiant heating (hereinafter referred to as "floor heating") is increasingly recognized by users. If underfloor heating users account for a large proportion, and some traditional radiator users are mixed in the load area, and they do not have the conditions to build a separate station, they can only use one set of systems for heating, so that when the floor heating users reach the room temperature requirement, the traditional heat dissipation Heater users often have unsatisfactory heating effects or even fail to meet standards;

(3) For radiator users, the form, heat dissipation effect, and service life of the radiator used are uneven, and the number of original radiators does not match the heating area and other reasons also cause the heating effect to be unsatisfactory or even not up to standard. Important factor

　　 (4) The pipe is leaking. When water leakage is caused by pipeline corrosion or unforeseen reasons, if it cannot be found and repaired in time, and the water loss is greater than the amount of condensed water, the system must be filled with tap water to maintain pressure. This will hardly increase the temperature and will inevitably affect the heating effect. And cause a lot of waste;

(5) Individual users install heat exchangers or discharge water from the system pipes. These conditions will make the return water temperature too low. When the water loss is large, it can also cause disadvantages to the heat user circulation at the high point of the system, or even without water. Can not circulate, directly affect the heating effect.

　　 Review new hot users to ensure service quality

In order to effectively maintain the interests of both heat supply and use and allow heat users to enjoy high-quality heating services, new heat users must actively cooperate and provide relevant information to make the indoor system meet the grid access requirements, so that the heating unit can use heat according to the heat users Consider the actual heating capacity of the pipe network, and determine whether it can be connected to the network. If the network access conditions are met, it is also convenient to arrange the pipes reasonably to ensure the heating effect.

　　 All departments of the thermal system are included in the thermal special management

　　 Although the heat supply and use agreement clarified the boundary point of the property rights and management scope of the two parties. But heating is different from water supply, power supply, and gas supply. The fundamental point is that the heating system of the two parties is an inseparable overall circulation system. The district pipe network of the heating unit is designed based on the distribution of the heat load, and the user’s heat usage, the service life of the facility, and the size of the pipe diameter are uneven, which further increases the imbalance of the thermal system. As a result, the supply and use of heat have caused a greater negative impact. Therefore, it is recommended that before the user applies for an account, the heating unit should conduct a comprehensive assessment of the user's location and heating facilities, and only those who meet the requirements can be connected to the network, otherwise, they are advised to make corrections. In this way, all parties involved in the design, management, and use of the thermal system are included in integrated management. In addition to the planning and design of the regional pipeline network, the heating unit must also put forward network access requirements for the design of new buildings and heating facilities, and provide technical support. In this way, the entire heating system can become an economic, reasonable and complete whole.
