Multi-couple unit operation state control method and system and heat pump multi-couple unit

Abstract

The invention relates to a multi-couple unit operation state control method and system and a heat pump multi-couple unit. The control method comprises the steps that the target operation mode of eachindoor unit is determined according to the operation mode, set by a user, of the indoor unit; the heat exchange quantity demands of the indoor units corresponding to the different target operation modes are counted, and the leading operation mode of the target operation modes is judged according to the heat exchange quantity demands; and the leading operation mode serves as the operation mode of an outdoor unit. By means of the control method, when the operation mode of the outdoor unit is determined, the expected operation mode of each user is comprehensively considered quantificationally, sothat the operation mode of the outdoor unit meets the actual heat exchange requirement of a majority of users, the control mode can be more suitable for meeting the actual use requirement of a majority of users during use, and accordingly the user experience is improved and user complaint can be reduced when the system is used on public places like office buildings.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a method and system for controlling the running state of multiple heat pumps, and a heat pump multiple heat pumps. Background technique [0002] A multi-connected system refers to an air-conditioning system in which one or more outdoor units are connected to multiple indoor units. The heat pump multi-connected system can operate in cooling mode or heating mode, but the indoor unit cannot operate in a mode that conflicts with the outdoor unit. [0003] At present, the operating mode of most outdoor units is determined by the main indoor unit mode in the multi-split unit, but the way of judging this mode is not free and democratic enough, and it is easy to cause user complaints when used in public places such as office buildings. [0004] For this reason, another control method of preset priority operation mode has appeared in the prior art. When the user has speci...

Problems solved by technology

This control method can avoid the abnormal operation of the air conditioner caused by the selection mode conflict or misoperation by setting the priority operation mode, and improve the convenience of the user. However, since the priority operation mode is preset according to the demand, It does not reflect the actual needs of all users, so this control method still lacks freedom and democracy when used, and it may also cause complaints from some users when used in office buildings and other places
