Problems solved by technology

This method takes the indoor temperature as the constraint condition, which is closer to the user's needs. However, due to the need to establish a room temperature database, it is necessary to collect a large amount of user room temperature data, which will undoubtedly increase the initial investment.

Abstract

The invention discloses a method for judging thermal misadjustment of a heating system based on typical user room temperature and a household heat meter. The method comprises the following steps: A, selecting one user from each type of users as a typical user; respectively placing a room temperature sensor and a household heat meter in the room of the typical user; B, according to set room temperature tn, sp, outdoor daily average dry-bulb temperature tw, av and room temperature tn, ac(i) actually measured by the room temperature sensor, correcting actual heat consumption Quser, ac(i) of the typical user, and obtaining heat needed Quser, th(i) of the users of each type under the set room temperature; C, comparing actual heat consumption and heat needed of each user of the same vertical pipe to perform misadjustment judgement, and comparing actual heat consumption and heat needed of each heat entrance to perform horizontal misadjustment judgement. The method provided by the invention issimple and easy to carry out, low-investment, highly operable, and beneficial for simplifying thermal misadjustment judgement operations and reducing judgement cost.

Description

technical field [0001] The invention relates to the technical field of a method for determining thermal imbalance in a heating system, in particular to a method for determining thermal imbalance in a heating system based on a typical room temperature and a household heat meter. Background technique [0002] The thermal imbalance of the heating pipe network is common in the heating system pipe network, often causing overheating at the near end and overcooling at the far end, which not only reduces the efficiency of the heating system, but also deteriorates the quality of heating supply, directly affecting the thermal comfort of users and the energy consumption of the system . At present, the commonly used heat balance judgment methods include flow judgment method and return water temperature judgment method. The basic idea of ​​using flow rate to determine thermal imbalance is to determine the loop with the highest flow imbalance degree as the most unfavorable loop by readin...
