Embodiment Construction

[0023] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention.

[0024] It should be noted that, in the description of the present invention, the terms "first" and "second" are only used for description purposes, and cannot be understood as indicating or implying relative importance.

[0025] Based on the problem pointed out in the background art that the existing air-cooled maglev air-conditioning units cannot simultaneously have a single-compressor start / stop mode and a dual-compressor start / stop mode, so that the cooling capacity adjustment range of the air-cooled maglev air-conditioning units is limited. The present invention provides an air-cooled magnetic levitation air conditioner unit and its contro...

Abstract

The invention belongs to the field of air conditioners, aims to solve the problem that the regulation range of the refrigerating capacity of an air-cooling magnetic levitation air conditioning unit islimited due to the fact that the existing air-cooling magnetic levitation air conditioning units cannot have a single-compressor start / stop mode and a double-compressor start / stop mode at the same time, and provides an air-cooling magnetic levitation air conditioning unit and a control method thereof. The control method comprises the steps as follows: acquiring environment temperature and outletchilled water temperature; selecting the start mode of the air conditioning unit according to at least one of the environment temperature and the outlet chilled water temperature. The air conditioningunit comprises a controller for executing the control method. By the aid of the air-cooling magnetic levitation air conditioning unit and the control method thereof, the regulation of the refrigerating capacity of the air conditioning unit cannot be limited, and the start mode of the air conditioning unit can be more flexible.

Description

technical field [0001] The invention belongs to the field of air conditioners, and specifically provides an air-cooled magnetic levitation air conditioner unit and a control method thereof. Background technique [0002] At present, air-cooled maglev air-conditioning units are installed in central air conditioners, and dual compressors are installed in air-cooled maglev air-conditioning units. Compared with air-cooled maglev air-conditioning units equipped with a single The cooling capacity of the air-conditioning unit has a large adjustment range, and when one of the compressors fails / alarms, the other compressor can maintain the normal operation of the air-cooled maglev air-conditioning unit. [0003] However, in the existing dual-compressor air-cooled magnetic levitation air-conditioning unit, two compressors share a group of pipelines. When one compressor fails / alarms, another compressor is started, which cannot fully utilize the dual compressors; When the compressors ha...
