Air conditioning unit and control method and control device thereof

Abstract

The invention discloses an air conditioning unit and a control method and a control device thereof. The method includes the following steps: according to total number of air-outlet air valves of the air conditioning unit and total regulation capacity of the air conditioning unit, computing rated regulation capacity distributed to each air-outlet air valve; according to the number of opened air-outlet air valves, computing and controlling opening air levels of an indoor unit; according to set temperature and the rated regulation capacity of an area where each air-outlet air valve is located, computing actual regulation capacity of each air-outlet air valve; summing the actual regulation capacities of all the air-outlet air valves to obtain total regulation capacity needed by the air conditioning unit, and controlling a compressor to run according to the total regulation capacity. One air-outlet air valve and a temperature controller are arranged in each regulation area independently, the opening air levels are controlled according to the number of the actually-opened air-outlet air valves, the actual regulation capacities of all the areas are integrated to control the compressor to run as required, multiple regulation areas are controlled centralizedly, and comfort and energy conservation requirements are met.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a control method, a control device and an air conditioner unit. Background technique [0002] At present, for a one-to-one unitary unit, generally one unit is used in one area, and one set of controllers is used for control. But for light commercial units (such as 3P and above), it can be used in a small office area, villa, shopping mall and other places. Using a set of outdoor unit and indoor unit, the indoor unit transmits cooling (heat) to different rooms through the air supply pipe, but in terms of control, it can only control the start and stop of the whole unit at present, and different rooms can only be turned on at the same time. Turn off at the same time, which will cause a certain waste of cooling capacity and electricity. Contents of the invention [0003] Based on this, it is necessary to provide an air-conditioning unit control method, a control device and an ...
