air energy heat pump double-effect normal temperature vacuum evaporation equipment uses a complex and sophisticated control system to coordinate the operation of the air energy heat pump system to ensure the efficiency, stability and safety of the entire evaporation process.
1. Sensor network
First, the control system is equipped with a variety of sensors. Temperature sensors are distributed in various key parts of the air energy heat pump, such as the inlet and outlet of the evaporator, the condenser, and the material inlet and outlet of the evaporation equipment. These sensors can monitor temperature changes in real time and feed back temperature data to the control system. For example, by monitoring the air temperature at the inlet of the evaporator, the control system can determine the heat supply potential of the air source. Pressure sensors are used to monitor pressure changes in the heat pump system, especially at the inlet and outlet of the compressor and during evaporation and condensation. In addition, there are flow sensors to monitor the flow of circulating media (such as water or refrigerant) to ensure that heat can be transferred and distributed in a predetermined manner during the double-effect evaporation process.
2. Intelligent controller
Based on the data fed back by the sensors, the intelligent controller becomes the core of coordinated operation. The intelligent controller uses advanced microprocessor technology and has a built-in special control algorithm. For air energy heat pump systems, it can adjust the speed of the compressor according to the evaporator temperature. When the evaporator temperature is low, indicating insufficient heat absorption, the controller will increase the compressor speed to enhance the evaporation effect, otherwise it will reduce the speed to avoid energy waste. In terms of the coordination of double-effect normal temperature vacuum evaporation, the controller will adjust the heating or cooling mode of the heat pump according to the temperature and pressure requirements during the double-effect evaporation process. For example, when the first-effect evaporation requires more heat, the controller will give priority to directing the heat generated by the heat pump to the first-effect evaporator.
3. Application of frequency conversion technology
The control system uses frequency conversion technology to accurately control the key components in the air energy heat pump. Taking the compressor as an example, through frequency conversion control, the compressor can operate at different speeds according to the actual heat demand. When the double-effect normal temperature vacuum evaporation equipment is in the startup stage or needs to heat up quickly, the compressor can run at high speed to provide sufficient heat. In the stable operation stage, according to the feedback from the temperature and pressure sensors, the compressor speed can be reduced to a suitable level to maintain a stable evaporation temperature and pressure, and achieve energy-saving operation.
4. Safety and protection mechanism
The control system also has a complete safety and protection mechanism. When the sensor detects abnormal temperature, pressure or flow, such as compressor overheating, system pressure too high or refrigerant flow too low, the control system will take immediate action. It can prevent equipment damage by reducing compressor load, adjusting valve opening or issuing alarm signals, ensuring the long-term stable operation of air energy heat pump double-effect normal temperature vacuum evaporation equipment.
