In the refrigeration process, the compressor is frequency-controlled and has obvious energy-saving effect: when the actual load is less than the rated load, the compressor runs at low speed, which reduces the compression ratio, which can not only improve the compressor efficiency. The output power of the compressor, and the condensation temperature and condensing pressure are lowered, and the refrigeration coefficient COP is increased. Another feature is that the chiller can operate continuously under the optimal working conditions under different loads, and the temperature requirements for freezing and refrigerating are fluctuated. Small occasions are more suitable. Schematic diagram of air conditioning variable frequency variable air volume control system - controller; - blower; "return fan" - "frequency control device; - controller; - electric damper; - pressure sensor; - temperature sensor diagram chiller frequency conversion speed control system principle Figure - compressor; - condenser; - liquid storage; "expansion valve; - evaporator; - pressure sensor; - frequency conversion speed controller focus on the "frequency conversion technology" column compressor frequency control, is a constant torque The type of load is generally proportional control. After the energy-saving effect analysis and calculation adopts the frequency conversion speed regulation technology, the system circulating flow is variable flow control, and the energy-saving effect is the most obvious, which can be calculated according to relevant theories and experience. Energy-saving principle of frequency conversion speed-regulating pump Inverter note In the water treatment industry, AC frequency conversion speed control devices are generally divided into two series, one is ordinary type, the other is high-performance type, which is suitable for low-demand fan pump Types of speed control for compressors and other applications where wide speed range is required. It can be seen that the speed control method has a large energy saving effect. Asphalt mixing plant is one of the key equipment for road construction. It is mainly used in the production of asphalt mixture for paving road surfaces. Asphalt mixing plant consists of a number of parts, including dosing system, dryer, agitator, dust removal system, fuel system and so on.

The batching system is one of the core parts of Asphalt mixing plant. It is responsible for adding various raw materials to the blender in a certain proportion. These raw materials include asphalt, sand, gravel and other additives. The batching system usually consists of a weighing sensor, a batching bucket and a batching transfer device.
The dryer is another important part of the Asphalt mixing plant. It is mainly used for drying raw materials such as sand and stones. There are heating elements and rotating agitators inside the dryer, which can make the raw materials fully heated and mixed evenly.
Mixer is one of the core parts of Asphalt mixing station. It is responsible for mixing various raw materials together to produce a high quality asphalt mixture. The agitator usually consists of multiple mixing blades, which can fully mix the raw materials to ensure the stable quality of the asphalt mixture produced.
Dust removal system is one of the important components of Asphalt mixing plant. It is mainly used to collect dust and exhaust gases generated during the production process. The dust removal system is usually composed of multiple filters, which can effectively filter out dust and exhaust gas to ensure a clean working environment and air quality.
Fuel system is one of the key parts of Asphalt mixing plant. It is responsible for providing the fuel to power the Asphalt mixing plant. The fuel system usually consists of a fuel pump, a fuel filter and a fuel injector.
Asphalt mixing plant is a kind of high efficiency asphalt mixture production equipment, widely used in road construction field. It has the advantages of high automation, high production efficiency, stable product quality and so on, and provides a strong support and guarantee for road construction.
