Method and system for cleaning air conditioner and air conditioner

InactiveCN105352128AAchieve breedingTo achieve the purpose of high temperature sterilizationMechanical apparatusSpace heating and ventilation safety systemsEngineeringState of the Environment
The invention discloses a method and system for cleaning an air conditioner and the air conditioner. The method comprises the following steps that the operating state of the air conditioner before operation is stopped is detected; when the operating state of the air conditioner before operation is stopped is a refrigerating pattern, heating elements are on until the environment temperature in an air channel of the air conditioner reaches a preset temperature, wherein the heating elements are arranged in an air outlet, an air inlet and / or the air channel of the air conditioner; and according to the dry state of the environment in the air channel, the heating state of the heating elements is controlled. According to the method, the heating elements are started to heat the air channel, and thus the purpose of killing bacteria in the air channel through the high temperature is achieved. In addition, the state of the heating elements is controlled according to the dry state of the environment in the air channel, and the effects of thoroughly sterilizing and cleaning the interior of the air channel are achieved. Finally, the problems that by means of the automatic cleaning function of a traditional air conditioner, only part of bacteria can be eliminated, and comprehensive and effective cleaning cannot be achieved are effectively solved.

Greenhouse environment intelligent control method based on global variable prediction model

The invention belongs to the technical field of facility agriculture environment control, and environment factors such as temperature, humidity, illumination intensity, CO2 concentration and the like in a greenhouse can be intelligently controlled. According to the greenhouse environment intelligent control method, a concept of a global variable is set, internal and external environment parameters in the greenhouse, current operating states of all controllers and local weather forecast for the next eight hours are used as all variables of a system, so as to be called global variables; and on this basis, a greenhouse environment prediction model based on the global variables is provided, and a BP (Back Propagation) artificial neural network is adopted to establish the model. By utilizing the model and combining fuzzy control, the greenhouse environment control method based on the global variables is invented. The greenhouse environment control method comprises the following steps that all of the global variables are used as input values, internal environment states of the greenhouse are predicted, and advanced adjustment is performed by the controllers in accordance with prediction results. By using the greenhouse environment intelligent control method, the problems of response lag, passive adjustment, inconsistent adjustment of the controllers and the like of traditional greenhouse environment control are solved, lag and oscillation in a response process are reduced, and the quality control of the greenhouse is improved.
