Description of the problems of industrial air conditioning systems and their solutions
| Description of the problem | Recommended solution | Results |
| Due to high starting currents, cables with a large cross-section must be used. Overcurrent leads to voltage drop, disrupts the normal operation of contact equipment, and reduces lifespan. | The use of frequency converters or soft starters can significantly reduce or even completely eliminate starting current loads, as well as mechanical shock loads. | Reduced repair costs for compressors, motors, and contact equipment, extended service life. |
| The speed of the drive shaft does not change with variations in pressure and temperature, leading to accelerated wear of parts and assemblies, as well as increased energy losses. | The application of a PID controller in the frequency converter allows for the adjustment of flow and pressure by changing the speed of the shaft according to the required mode. | Significant savings in consumed electricity, optimization of process parameters, extended service life of equipment, reduced repair costs. |
| Short-term power outages due to high inertia torque do not lead to an immediate stop of the fans. The draft in the duct can cause reverse rotation of the fans, leading to mechanical shocks and surges in starting current. | The use of a built-in "catch-up" feature in the converter ensures a smooth, unforced start of the drive, even if the shaft is rotating in the opposite direction. | Reduced repair costs for drive units, decreased likelihood of breakdowns, extended service life. |
| In certain sets of operating parameters, resonance may occur between the fan and structural elements, which increases noise levels and likelihood of breakdowns. | The converter is equipped with the ability to adjust the bypass of four zones of values that cause resonance, ensuring uninterrupted operation of the drive and the system as a whole. |
Advantages of using frequency converters
The use of frequency converters to control air conditioning and ventilation systems instead of traditional methods allows for:
- elimination of motor overloads due to current;
- elimination of belt slipping;
- reduction of electricity consumption by 10-50%;
- automatic maintenance of required pressure and temperature indicators in the room;
- elimination of the need for complete restart of the technological process in case of short power outages.
Comprehensive solutions for the management system
There is a possibility to create a comprehensive management system for all equipment included in the line or installation, with further integration into the dispatch control system of the entire enterprise. This will require several additional controllers.
