Embodiment Construction

[0060] The technical solutions of the various embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0061] In the existing multi-connected air conditioning system, the number of indoor units connected through the wire controller is relatively limited, and due to the limitation of the number of digits of the dial code for the load capacity of the main control board, it is impossible to increase the operating load capacity of a single indoor unit, that is, a single indoor unit The load capacity of the machine is limited by the number of digits of the load capacity dial on the main co...

Abstract

The invention discloses an indoor unit loading capacity control system and an indoor unit loading capacity control method. The system comprises indoor units, main control panels and a power control panel, wherein the power control panel supplies voltages needed for the working of the main control panels; the main control panels are connected with the indoor units, generate corresponding loading capacity control signals expressed in loading capacity dialing digits and output the loading capacity control signals to the indoor units; the indoor units receive the loading capacity control signals output by more than two main control panels, combine the loading capacity control signals with a preset reference value of loading capacity dialing digits to obtain indoor unit loading capacity corresponding to all loading capacity control signals, carry out accumulation, and set the indoor unit loading capacity to accumulated indoor unit loading capacity, and the more than two main control panels are connected to the indoor units in a parallel mode. By the application of the indoor unit loading capacity control system and the indoor unit loading capacity control method, the develop cycle when a multiple on-line air conditioning system is upgraded can be reduced.

Description

technical field [0001] The invention relates to multi-connected air conditioner control technology, in particular to an indoor unit load capacity control system and an indoor unit load capacity control method. Background technique [0002] With the acceleration of the domestic urbanization process, the number of clustered buildings continues to increase, and at the same time, the improvement of people's living and working environment comfort requires that the total load capacity that the multi-connected air conditioning system as the main air conditioning system can carry continues to increase. Increase to adapt to the continuous expansion of the scale of clustered buildings. [0003] The multi-connected air conditioning system is mainly used to control the indoor temperature and humidity, and generally consists of one or more outdoor units, wire controllers and an indoor unit load capacity control system. Wherein, the wire controller is connected with the indoor unit load ...
