Zen air Dirty - blockage Identification Algorithm

The Zen Air true dirty - blockage identification for constant - air - volume indoor units uses digital twin technology to help users avoid an average annual energy consumption loss of 15%. Coupled with the full - data refrigerant diagnostic analysis Doctor M, which uses all - quantity sensors to diagnose and identify unnecessary performance degradation, users can reduce more unnecessary electricity expenses.

iBUILDING - Let Smart Control Bring a New Experience

Smart Cloud Butler - Easier Project Management

Midea Cloud Control allows users to obtain air - conditioner control rights through account authorization, enabling functions such as schedule management, zoned control, mode setting, temperature adjustment, wind speed adjustment, air - swing adjustment, energy - saving control, and operation reporting. Users can view the complete operating status of the air conditioners anytime and anywhere and conduct centralized management of the air conditioners in the area, which is intelligent and convenient.

Midea's new platform for centralized control has achieved the online data of a large number of global projects and devices, providing data support for intelligent control and service upgrades. It has realized an intelligent air - conditioner comprehensive solution integrating online project and equipment management, cloud - based control of building equipment, mobile - end support at the installation site, and mobile remote control, effectively empowering users.

Energy - saving Analysis Platform - A Strong Support for Optimizing Operating Costs

The energy consumption of the generalized air - conditioning system (including cooling, dehumidification, heating, hot water, etc.) accounts for more than half of the total energy consumption of building operation. Midea's energy - saving analysis platform monitors the energy consumption during the whole - life - cycle operation of the air conditioner, shows the air - conditioner energy - consumption report to users, and based on big - data analysis, deeply identifies the energy - saving potential and provides users with the optimal control strategy to improve the annual comprehensive energy efficiency of the unit.

Ø Comprehensive Display of System Energy Consumption

Monthly energy - saving analysis is carried out on a project - by - project basis. Energy consumption is calculated in the order of electric meter data, State Grid metering module data, and the CC method, and the algorithm results are output for front - end display. The energy consumption values for the current year, this month, and today, as well as the year - on - year values, are calculated based on real - time energy consumption statistics.

Ø Big - data Analysis

Based on big - data analysis of excessive energy consumption, the proportion of excessive energy consumption, the time of excessive energy consumption, and other information, one - click optimization of energy - saving control is pushed. Schedule plans can also be set and recommended. It truly meets users' needs for comfort and reducing operating costs.

Ø Deep Identification of Energy - saving Potential

The corresponding PMV level is calculated according to important parameters such as set temperature, mode, wind speed, and ambient temperature to identify over - cold and over - hot set temperatures, thereby adjusting the control strategy.

Ø Energy - saving Strategy Push

Based on the statistical energy - saving analysis results, relevant energy - saving strategies are pushed. For example, for the situation of forgetting to turn off the machine, an optimized schedule plan is recommended to achieve automatic on - off, avoiding energy waste.
