Embodiment Construction

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

[0038] like figure 1 Shown is a flow chart of the specific 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 between rooms in a commercial building

[0040] 1.1 Considering the sum of the cooling loads of each room in the commercial building, the following central air-conditioning power model is established:

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

[0042] of which: P AC is the power of the central air conditioner, 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 the cooling tower power, P coolingpump is the cooling water pump power; due to P pump , P coolingpump and P coolingtower The proportion of...

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 power demand response, and mainly relates to a strategy for commercial buildings to participate in demand response. The strategy is based on a central air-conditioning model based on room differences in the building, and based on the principle of equal comfort loss, formulates a business building through the central air-conditioning load. Cut back 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. In view of the current large 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 an important demand response resource. The main equipment for commercial buildings to participate in demand response is the central air-conditioning system in the building. The...
