Description
Technical Field
The invention relates to the technical field of heating system evaluation, in particular to a method, a device and a system for determining room temperature stability.
Background
Generally, in a predetermined heating system, the heat insulating performance, heat dissipating equipment, etc. of a building exterior protective structure are fixed, which affects the building indoor temperature, only the outdoor temperature and the heating load. Since outdoor weather is variable and uncontrollable, in order to ensure that the indoor temperature reaches the desired target, the heating load of the heating system is adjusted to adapt to the variation of the outdoor weather.
In a state where the heat dissipation amount of the radiator and the heat consumption amount of the building to the outside are in thermal balance, the heat consumption amount of the building can be calculated by the following calculation formula:
Q＝qvVw(tn-tw) Wherein Q is the heat consumption of the building, QvV is the heat consumption of a building when the indoor temperature difference is 1 DEG CwIs the peripheral volume of the building, tnIs the room temperature, twIs the outdoor temperature.
Wherein q isvAnd VwIs a constant. This can be deduced from the above formula:as can be seen from the formula, the indoor temperature has a direct relation with the number heat of the building and the outdoor temperature.
The inventor finds that the indoor temperature of a main room of a user is usually obtained by a heat supply management enterprise through manual temperature measurement or a room temperature acquisition system, but quantitative indexes for evaluating the heat supply service effect are lacked after the room temperature is obtained, and the room temperature condition of the user is usually counted by adopting three algorithms of highest, lowest and arithmetic mean. However, these three algorithms do not accurately reflect the ability to maintain the room temperature of the user through the operation and control of the heating system.
Specifically, the average room temperature can only show an average value in time periods, and if sudden operation such as window opening of a hot user, heating equipment stop and the like can cause extreme room temperature, the values influence the average value, the extreme room temperature also influences the maximum room temperature and the minimum room temperature of the room temperature, if two groups of room temperature data (16, 18, 20) and (14, 18, 22) exist, the arithmetic average value of two groups of sample data is 18, but the deviation of the room temperature is large, and the heating is to ensure that the room temperature of all users reaches the standard, and the common maximum, minimum and arithmetic average values cannot show the stable condition of the room temperature in a certain time period.
Therefore, how to provide room temperature stability determination methods, apparatuses, and systems to maintain the user room temperature is an urgent technical problem to be solved by those skilled in the art.
