Embodiment 1

[0060] Such as figure 2 As shown, a start-stop control device for an air-conditioning system based on indoor thermal comfort conditions for large public buildings, an indoor data acquisition device 1 , an outdoor data acquisition device 2 , a computing controller 3 and an electric valve 4 .

[0061] Described indoor data acquisition device 1 (manufacturer's custom-made) comprises humidity sensor I 1-1, temperature sensor I 1-2, black ball temperature sensor I 1-3 and wind speed sensor I 1-4, is installed in the building indoor apart from ground 1.1. meters and 0.5m away from the wall. The data output terminals of the indoor data acquisition device 1 are respectively connected to the computing controller 3 through matching data connection lines.

[0062] The outdoor data acquisition device 2 (customized by the manufacturer) includes a humidity sensor II 2-1, a temperature sensor II 2-2, a black ball temperature sensor II 2-3 and a wind speed sensor II 2-4, and is installed in...

Embodiment 2

[0066] Such as figure 1 As shown, an air-conditioning system start-stop control device for residential buildings based on indoor thermal comfort conditions is the same as that of Embodiment 1, and the feature is that the calculation controller 4 is a commercially available (manufacturer customized) load with estimated adaptive average heat The single-chip microcomputer of the sensory index APMV calculation and comparison program is placed next to the indoor air conditioner.

[0067] The calculation process of the calculation controller 3 carrying the predicted adaptive average thermal sensation index APMV calculation and comparison program includes the following steps;

[0068] 1) Partial parameter values ​​are set in advance in the calculation controller 3 program, and the parameter values ​​include human energy metabolism rate M=69.78W / m 2 , mechanical power W=0W / m 2 , the ratio of the actual surface of the dressed human body to that of the naked human body: f in summer c...

Embodiment 3

[0097] Such as figure 1 As shown, the control method of the start-stop control device of the air-conditioning system based on the indoor thermal comfort state includes the following steps:

[0098] (1) At the beginning, some parameter values ​​are set in advance in the program loaded by the calculation controller 3, and the parameter values ​​include human energy metabolism rate M=69.78W / m 2 , mechanical power W=0W / m 2 , the ratio of the actual surface of the dressed human body to that of the naked human body: f in summer cl = 1.1, winter f cl = 1.63, choose AC, AD, BC or BD according to the specific circumstances of the building climate zone and building type.

[0099] (2) The computing controller 3 issues a closing command to the electric valve 4 to control the indoor air conditioner not to run, issues a starting command to the indoor data acquisition device 1, and issues a closing command to the outdoor data acquisition device 2.

[0100] (3) calculation controller 3 re...

Abstract

The invention discloses an air conditioning system startup and shutdown control device based on an indoor heat comfort state and a control method. The device comprises an indoor data acquisition device, an outdoor data acquisition device, a computation controller and an electric valve. The indoor data acquisition device and the outdoor data acquisition device respectively comprise a temperature sensor, a humidity sensor, a black-bulb temperature sensor and a wind speed sensor, are respectively connected with a data inlet end of the computation controller, and form linkage control together with the electric valve. The computation controller is loaded with an adaptive predicted mean vote computation and comparison program. The electric valve is connected with the computation controller through a data connecting line and is connected with an original air condition system control box through a conducting wire. The control method of the device disclosed by the invention comprises the steps of comparing with an adaptive predicted mean vote obtained by the computation controller, giving out, by the computation controller, an action instruction to the electric valve, and then controlling the startup and shutdown of an indoor air conditioning system and the turning-on and turning-off of the indoor data acquisition device and the outdoor data acquisition device.

Description

technical field [0001] The invention belongs to the application of computer control technology in air-conditioning system control, in particular to a start-stop control device and control method of an air-conditioning system based on indoor thermal comfort state. Background technique [0002] As time goes by, human beings promote the progress of society through continuous innovation and development, and their ultimate goal is to improve their own living environment. In today's society, people's living standards have been greatly improved, and people are paying more and more attention to their living environment. Among them, the indoor environment is an important part of people's living environment. Many of people's work, rest, entertainment and other activities are carried out indoors. The quality and comfort of the indoor environment are directly related to people's quality of life and physical health. So it is very necessary to create a healthy, comfortable and clean indo...
