Problems solved by technology

[0008] As mentioned above, although the loading or unloading control method of the existing modular unit can adapt to the change of the load of the air conditioning system, since the air conditioning system operates under the partial load state most of the time, it makes the existing load Or the unit module under the control of the load reduction control mode is always in the operating state of 0% or 100%, so that the high performance of the unit module at part load cannot be fully utilized, and the energy-saving operation of the unit module at part load cannot be fully utilized effect, thus increasing the operating cost of the air conditioning system and affecting the overall operating efficiency of the system

Abstract

The invention provides a method and system for loading and deloading a unit module in a module unit. The method comprises: a) determining the unit module required to operate in the module unit and judging the energy transfer state of the unit module; b) searching whether preferentially loaded unit modules exist in the unit module required to operate, wherein the preferentially loaded unit modulesare the unit modules with the energy transfer which is 0% in the unit module required to operate; c) if the preferentially loaded unit modules are available, loading one of the preferentially loaded unit modules, or, loading any one of the unit modules required to operate at random; and d) finishing loading. The method and system for controlling (loading / deloading) the unit module in the module unit are provided so that the air conditioning system operates in the partial load state more. Therefore, compared with prior control mode, the invention has remarkable energy-saving effect so as to effectively reduce the operating cost of the system.

Description

technical field [0001] The present invention relates to a method and a system for controlling the operating modes of unit modules in a modular unit, more particularly, the present invention relates to a method and a system for loading unit modules in a modular unit, and for controlling the unit modules in a modular unit Method and system for load shedding. Background technique [0002] Modular unit groups (referred to as modular units) are widely used in air-conditioning systems. Usually, a modular unit includes multiple (two or more) unit modules that can operate independently, and each unit module includes one or more compressors. Among them, the modular unit can be used for a shared chilled water system, a shared cooling water system, a shared refrigerant system, a shared air system, or a combination of two or more of the above shared systems. When the user changes the load demand on the air conditioning system, the module unit responds to the command of the centralized...
