Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Such as figure 1 As shown, taking a modular multi-connected air-conditioning system combined with three external unit modules as an example, the present invention and its specific implementation methods are described in detail. The three-module multi-connection unit is composed of three 10HP outdoor units connected in parallel, and each outdoor unit is composed of two 5HP frequency conversion multi-connection units. The frequency conversion compressor is characterized in that: 5HP is the The actual capacity range is 2~8HP, and the capacity range for high-energy-efficiency operation is 3.5~6.5HP (generally provided by the compressor manufacturer). The frequency conversion compressors of the host are marked as B1 and B2 respectively, wherein B1 has a higher priority than B2. The frequency conversion compressors of the auxiliary machine 1 are res...

Abstract

The invention relates to a modular multiple on-line control method. Indoor units and outdoor units are included, wherein each outdoor unit comprises an inverter compressor. The control method includes the following steps that first, the capacity requirement Q of the indoor units is calculated; second, the number N of the outdoor units needing to be turned on is determined; third, the turned on outdoor units are allocated according to weight; fourth, all the outdoor units determine the number of the compressors to be turned on and the operating frequency of the inverter compressors according to the allocated capacity. The control method is reasonable in procedure, simple in control and capable of playing the multiple on-line energy-saving potential. Meanwhile, due to the fact that all the inverter compressors can operate within a high-efficiency range through the method, the phenomenon that because the operating frequency is too high, the compressors are lack of oil or burnt to be damaged can be avoided, and the operating reliability and the service life of all the compressors can be effectively guaranteed.

Description

technical field [0001] The invention relates to a control method of a multi-connected air conditioner, in particular to a modular multi-connected control method. Background technique [0002] At present, the multi-connected air-conditioning system develops rapidly and plays an increasingly important role in the field of central air-conditioning. Compared with traditional air conditioners, it has free control and fine adjustment, fully meeting consumers' requirements for comfort and convenience. At the same time, because its compressor adopts variable capacity technology, which is highly efficient and energy-saving, the market potential is unlimited. [0003] At present, mainstream air-conditioning equipment manufacturers all have multi-connected products, and their common feature is the combination of modules combined with variable capacity technology. The most popular combination of multi-connected modules on the market is: the main unit and auxiliary unit of the outdoor ...
