Embodiment Construction
[0040] The present invention will be described in further detail below in conjunction with specific examples, but the implementation of the present invention is not limited to this. The operation data processing method, the online long-term performance detection based on the predictive model and the optimization operation method changes are all protected by this patent. within.
[0041] Such as figure 1 Said, a room air conditioner online long-term performance detection and optimized operation method, including the following steps:
[0042] 1) Hourly measurement of air conditioner operating data, and transmit the parameters to the background server via GPRS. Through a period of data collection, the user's operating data for the past two months can be collected. The data format of a certain moment is as follows:
[0043] Table 1 Data format collected
[0044]
[0045] 2) Preprocess the operating data to obtain the data under the stable operating state of the air conditioner;

The invention discloses an online long-acting performance detection and optimized running method for a room air conditioner. The method includes the steps that firstly, air conditioner running data are measured hour by hour and saved; secondly, the running data are preprocessed, and data in a stable running state are acquired; thirdly, the air supply temperature and the like of the air conditioner in the data serve as input parameters, the power and the like of the air conditioner serve as output parameters, and a long-acting performance prediction model of the air conditioner is established, and the energy efficiency of the air conditioner is calculated; fourthly, the common running work condition of the air conditioner is determined, and performance parameter values under the running work condition are acquired based on the prediction model and serve as evaluation indexes; fifthly, preferentially designed indoor temperature and humidity of a current user are found out; and sixthly, an optimal running control model of the air conditioner under special outdoor temperature and humidity is established, and a control manner of the air conditioner is updated. The online long-acting performance detection and optimized running method for the room air conditioner can detect the performance state of the air conditioner in time; and meanwhile based on the using habit of the current user and the optimized running manner of the performance state of the air conditioner, the running energy efficiency of the air conditioner can be better improved while the using requirement of the user is met.
Description
Technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method for long-term performance monitoring and optimized operation of a room air conditioner. Background technique [0002] After the air conditioner is used for a long time, its performance will be attenuated to varying degrees due to heat exchanger corrosion, pipe fouling, component wear, etc., which will deviate from the factory state and affect the user's experience. With the implementation of the China Quality Certification Center "Implementation Rules for Continuous Energy-saving Evaluation of Air Conditioners in Use" and "Technical Requirements for Long-term Energy-saving Evaluation of Air Conditioners" standards, the long-term performance of room air conditioners has received attention. [0003] Although the long-term performance of the room air conditioner can be accurately obtained under laboratory conditions, in order to accurately grasp the performance changes of...
