Construct a heat transfer model. According to the stored indoor temperature records, combined with the formula of heat transfer inside the house, calculate the current heat storage situation in progress, so as to reflect the emergence of the best operating mode for heating in real time. The specific steps are as follows :

Step 1. Establish heat transfer function;

Step 11. The establishment of the indoor heat transfer function is mainly based on the heat difference between the electric heating film for the heat transfer of the indoor air and the indoor air for the heat transfer of the outdoor air. Set the indoor heat as Q, the indoor normal temperature heat as E1, and J1 as the electric heating film transfer. Heat, k1 is the heat transfer loss coefficient, J2 is the heat transfer from indoor to outdoor, k2 is the barrier coefficient of the wall in the process of heat transfer to the outdoors, a is the indoor retention coefficient of heat loss, the calculation formula of indoor heat is:

Q=E1+J1(1-k2)-J2(1-k1)+∑a*k1,

Step 12. The heat transfer function is further obtained, specifically:

H=Q/E1,

H=1+ J1(1-k2)/E1-J2(1-k1)/E1+1/E1(∑a*k1);

Step 2. Combine the existing temperature records to adjust the transfer function;

Step 21: Calculate the space size of the room where the heating device is used and record it as V1;

Step 22. According to the heating empirical formula, after combining the three data of the space size V1 of the house with the total amount of heating Q1 and the existing heating temperature T1, the heating stability coefficient M is obtained. The calculation formula of M is:

M=Q1/V1+V1*T1/Q1;

Step 23: Complete the final formula of the transfer function, specifically:

H={1+ J1(1-k2)/E1-J2(1-k1)/E1+1/E1(∑a*k1)}*M;

Step 3. According to the existing heat storage mode, select the corresponding heating mode; according to the actual data situation, calculate the size of the transfer function H, which is the size of the heat preservation capacity of the existing house, when H is at 0- When H is between 5, it means that the heat preservation ability is weak; when H is between 5-10, it means that the heat preservation ability is moderate; when H is greater than 10, it means that the heat preservation ability is strong.
