Embodiment Construction

[0020] Embodiments of the present invention are described in further detail below:

[0021] A method for estimating heat load of residential electric heating film heating, comprising the following steps:

[0022] Step 1. Taking the heating power required by each household in the residential area as the objective function, establish the heating load estimation formula of the residential electric heating film heating:

[0023] P=SK(t-t w )

[0024] Among them, S=ηS 0 +ΣS i +μΣS I ;t=t 0 +t 1

[0025] In the above formula, P is the required heating power (unit: W), S is the total area of ​​the equivalent heat dissipation wall based on a certain occupancy rate (unit: m 2 ), K is the equivalent heat transfer coefficient, t is the indoor temperature calculated based on the usage habits of each household in the residential area, t w Calculate the temperature for the outside (unit: W / (m 2 ·℃)), S 0 is the building area, η is the light level coefficient based on the unit typ...

Abstract

The present invention relates to a heating load estimation method of a residential electric heating film. The method comprises the following steps: step 1, using heating power required by each household in a residential area as a target function to establish a heating load estimation formula of a residential electric heating film: P=SK(t-tw), wherein in the above expression, P is the required heating power, S is an equivalent total area of a heat-dissipating wall based on a certain occupancy rate, K is an equivalent heat transfer coefficient, t is a calculated indoor temperature determined based on the usage habits of each household in the residential area and tw is a calculated outdoor temperature; and step 2, determining parameter values of tw, t, S and K in step 1 and putting the parameter values into the formula in step 1 to obtain the heating load value required by each household in the residential area by solving the formula. The estimation method enables each household to configure a reasonable heating load capacity according to the specific situation of the household to achieve comprehensive optimization on economic and heating effects.

Description

technical field [0001] The invention belongs to the technical field of electrothermal film heating, in particular to a method for estimating the heat load of residential electrothermal film heating. Background technique [0002] Electrothermal film heating technology is a technology that converts electrical energy into thermal energy to heat buildings. With the promotion of clean energy, the replacement of electric power from the grid has been carried out, and the electrothermal film heating technology is now gradually applied to the heating of community residents in many regions. For a specific community resident user, how to reasonably determine the required heating load and find a reasonable estimation method to achieve economical and optimal heating effect is of great significance. [0003] At present, the method of multiplying the heating power per unit area by the building area, which is usually used in practice, is simple, but it is relatively rough, and it has not b...
