Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings.

[0038] Such asfigure 1 Shown is the flow chart of concrete implementation steps of the present invention, and its detailed steps are as follows:

[0039] Step 1: Establish a central air-conditioning model that considers the differences of each room in a commercial building

[0040] 1.1 Consider the sum of the cooling loads of each room in a commercial building to establish the following central air-conditioning power model:

[0041] P AC =P fan +P pump +P chiller +P coolingtower +P coolingpump

[0042] Where: P AC is the central air-conditioning power, P fan is the total power of all fans at the end, P pump is the chilled water pump power, P chiller is the power of the refrigerator, P coolingtower is cooling tower power, P coolingpump is the cooling water pump power; due to P pump ,P coolingpump and P coolingtower The proportion in the system operation ...

Abstract

The invention discloses a central air conditioner load-reduction temperature-adjusting method based on an equal comfort level loss principle. The central air conditioner load-reduction temperature-adjusting method includes the steps that on the basis of a central air conditioner model, terminal set temperature values of all rooms and indoor cold load conditions of all rooms in a commercial building are considered; according to the principle that human body comfort level loss values of all rooms are equal, the load reduction lasting time of all rooms is obtained, then temperature adjustment control over all rooms is carried out, and load reduction of a central system is achieved. According to the central air conditioner load-reduction temperature-adjusting method, the user comfort level is sufficiently considered, the commercial building participates in demand responses to achieve load reduction, and the reasonability and the scientificity of a load reduction scheme are improved.

Description

technical field [0001] The invention belongs to the field of electric power demand response, and mainly relates to a strategy for commercial buildings to participate in demand response. The strategy is based on the central air-conditioning model based on the difference of rooms in the building, and according to the principle of equal comfort loss, the central air-conditioning load of commercial buildings is formulated. Cutting down on ways to engage in demand response. Background technique [0002] With the continuous increase of power system load, demand response technology has attracted more and more attention. For the current big cities with developed tertiary industry, the load of commercial buildings accounts for an increasing proportion of the total load, so commercial buildings are gradually being regarded as important demand response resources. The main equipment for commercial buildings to participate in demand response is the central air-conditioning system in the...
