Emergency operation method of air conditioning unit

Abstract

The invention belongs to the technical field of heat exchange equipment, and particularly relates to an emergency operation method of an air conditioning unit. The method aims to solve the problems that when partial indoor units of an existing air conditioning unit fail, the whole unit is shut down, and the use experience of all users is reduced. Therefore, the emergency operation method of the air conditioning unit can selectively enable the air conditioning unit to continuously operate for a period of time by combining the fault degree of the air conditioning unit and the current operation requirements of non-fault indoor units, so that the operation time of the non-fault indoor units can be prolonged when the fault degree of the air conditioning unit is light and the continuous operation condition is provided, the air conditioning unit can be continuously used by the users in rooms where other non-fault indoor units are located, the user range affected by fault indoor units is reduced, the condition that all users cannot adjust the temperature through the air conditioning unit once partial indoor units have faults is prevented, the maintenance waiting time of the users of the non-fault indoor units is shortened, and the use experience of the users is improved.

Description

technical field [0001] The invention belongs to the technical field of heat exchange equipment, and in particular relates to an emergency operation method of an air conditioning unit. Background technique [0002] With the increasing development of the economy and the continuous improvement of human living standards, the application of air conditioners is becoming more and more popular, and there are more and more application places. In addition to household air conditioners, large places such as apartments, office buildings, and commercial buildings generally use central air conditioners for cooling and heating. The refrigerant system of the central air conditioner usually includes multiple indoor units and one or more outdoor units, and the multiple indoor units are arranged in parallel to be distributed in different rooms for air conditioning. [0003] When the above-mentioned air-conditioning unit is actually working, due to the complexity and variability of its operati...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned problems in the prior art, that is, to solve the problem of shutting down the entire unit when some indoor units of the existing air conditioning unit fail, reducing the user experience of all users Problem, the present invention provides an emergency operation method for an air-conditioning unit, the air-conditioning unit includes at least one outdoor unit and a plurality of indoor units, the emergency operation method includes: in the case of an indoor unit failure, obtaining the failed The total number and total rated load of indoor units; judging whether the total number of faulty indoor units is greater than the set number; judging whether the total rated load of faulty indoor units is greater than the set load; if the total number of faulty indoor Not greater than the set number and the total rated load of the faulty indoor units is not greater than the set load, then determine whether the air conditioning unit has any indoor units that are still operating normally; If the indoor unit is running, the outdoor unit will be controlled to continue running for the preset time according to the current operating mode
