Abstract

The invention provides an energy-saving control method, equipment and medium of a multi-connected cold-hot water unit. The method comprises the following procedures of recording total power-and-time relationship during operation of a unit on the first day; calculating operating parameters-and-time relationship of the unit in the next day based on at least the total power-and-time relationship; andcontrolling the operation of the unit according to the operating parameters-and-time relationship. According to the method, the problem of low energy-saving performance of the multi-connected cold-hot water unit is solved, and the energy-saving performance of the multi-connected cold-hot water unit is improved.

Description

technical field [0001] The invention relates to the field of control of air conditioning units, in particular to an energy-saving control method, equipment and medium of a multi-connected hot and cold water unit. Background technique [0002] Multi-connected hot and cold water units, that is, the main machine first takes chilled water or hot water, and then sends it to the air conditioner at the end for users to adjust the air through pipelines. Compared with the multi-connected fluorine system, the multi-connected hot and cold water units have control delays due to the fact that there are many terminals connected to the main unit and heat exchange is performed by water. [0003] The external unit is connected to the terminals of multiple internal units through waterways. Since the group control design is required and the external units are directly controlled by the needs of the internal units, energy saving is a very important indicator. If the user is free to control, the...
