Embodiment Construction

[0072] In order to further set forth the technical means and effects that the present invention takes to achieve the intended invention purpose, below in conjunction with the accompanying drawings and preferred embodiments, the specific implementation, structure, features and effects according to the present invention are described in detail as follows:

[0073] Such as figure 1 Shown is the flow chart of water temperature control method of the present invention, and described water temperature control method comprises the following steps:

[0074] S1: Detection input: detect the actual temperature LT and water temperature change rate VT of the sampling period and input the detection results;

[0075] Specifically, taking the time Tc as a cycle, the water temperature T L , T L+1 , calculate the water temperature change rate V according to the water temperature T =T L+1 -T L ; At this time, the value of the measured temperature LT obtained is T L , to obtain the value of...

Abstract

The invention discloses a water temperature control method and device. The water temperature control method comprises the following steps that detection and input are carried out, and particularly actually-measured temperature LT and the water temperature change rate VT in a sampling period are detected, and detection results are input; comparison and judgment are carried out, particularly, the actually-measured temperature LT and the water temperature change rate VT are compared with set ranges of target temperature LTS and the water temperature change rate correspondingly; and output and control are carried out, particularly, according to the comparison results, corresponding energy control activities are achieved, the larger the actually-measured temperature LT compared with the targettemperature LTS and the water temperature change rate VT are, the larger the energy adjusting loading rate is. The water temperature control device comprises a detection and input module, a comparisonand judgment module and an output and control module. By means of the technical scheme, the water temperature control method and device have the beneficial technical effects that associated equipmentwater temperature control can be achieved, the response speed is high, and control is accurate.

Description

technical field [0001] The present invention relates to a water temperature control method and device, in particular to an energy-regulated water temperature control method and device for an evaporative condenser air-conditioning unit. Background technique [0002] The energy control method of existing chilled water air-conditioning units, especially evaporative condensing air-conditioning units, is the hysteresis control method, that is, when the unit is running, the compressor can only be loaded when the water temperature of the heat exchanger reaches the target or the target plus the hysteresis. When the target temperature or target plus hysteresis is reached, the compressor will be unloaded. [0003] For example, the Chinese invention patent CN 102927657 B discloses a method for controlling the water temperature by changing the speed of the temperature of the air conditioner. The specific steps are as follows: (1) collect the temperature data in the air conditioner area ...
