Embodiment Construction
[0023] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but not to limit the present invention.
[0024] Considering that most of the existing air conditioner emergency control methods simply set an emergency switch on the air conditioner, when the air conditioner fails, the emergency switch is manually controlled to perform emergency control of the air conditioner. When the above method is specifically implemented, due to the limitations of the method itself, it is impossible to carry out targeted and accurate control of the air conditioner according to the specific fault conditions and environmental conditions; it also requires human participation, that is, it cannot automatically...

The invention provides an air conditioner emergency control method and device. The method comprises the steps that whether preset failures of an air conditioner occur or not is detected, and the preset failures comprise the return air probe failure, the exhaust air temperature wrap failure, the evaporator outlet pipe temperature wrap failure and the evaporator inlet pipe temperature wrap failure;under the condition that the preset failures of the air conditioner occur, historical operation records of the air conditioner are obtained, wherein the historical operation records are generated according to preset regulations under the condition that the air conditioner works normally; according to the preset failures and the historical operation records, corresponding preset strategies are determined; and the air conditioner is controlled to operate according to the preset strategies. According to the method, under the condition that the failures occur, the historical operation records, generated during normal operation, of the air conditioner are obtained; and the corresponding preset strategies are determined automatically for air conditioner emergency control according to the historical operation records and the preset failures, so that the technical problem that the air conditioner cannot be controlled automatically, accurately, correspondingly and effectively under the failurecondition through existing methods is solved.
Description
technical field [0001] The present invention relates to the technical field of air conditioning control, and in particular, to a method and device for emergency control of air conditioning. Background technique [0002] Some air conditioners in air conditioners, such as computer room air conditioners, mostly serve electronic equipment such as computers, data processors, and program-controlled switches. For the service objects listed above, once this type of air conditioner fails, shuts down, or fails to cool the computer room, it will cause the temperature in the computer room to rise, resulting in the downtime of electronic equipment such as computers, processors, switches, etc. Damage to electronic equipment. Therefore, for the above air conditioners, the requirements are relatively high. It is generally required that the above-mentioned air conditioners can take some emergency measures in time when a failure occurs, so that the equipment room can be urgently cooled. ...
