In today's era of pursuing energy efficiency and environmental protection, the waste heat recovery system of exhaust heat pumps, as an innovative energy utilization technology, is receiving more and more attention and application from industries.

The concept of exhaust heat pump: Exhaust heat pump is a system that completes heat transfer by circulating working fluid through a compressor. Compared with traditional heating and cooling systems, the exhaust heat pump system has a higher energy efficiency ratio and can achieve heat transfer at lower energy consumption.

The rise of waste heat recovery systems: Waste heat recovery technology refers to the collection and reuse of waste heat generated in industrial processes, converting it into usable heat energy. The waste heat recovery system of the exhaust air heat pump has emerged in this context, fully leveraging the high efficiency of the heat pump system.

The basic principle of exhaust heat pump

Heat pump cycle process: The exhaust air heat pump adopts the principle of thermal cycle, and completes the energy transfer process through components such as compressor, expansion valve, evaporator, and condenser. During this process, the temperature and pressure changes of the working fluid in different states achieve heat transfer.

Compression and expansion process: In a heat pump system, low-temperature and low-pressure gases are compressed by a compressor to increase their temperature and pressure. Next, the high-temperature and high-pressure gas is released into a low-temperature and low-pressure state through the expansion valve, releasing heat. During this process, energy is transferred, achieving the extraction and utilization of thermal energy.

Working principle of waste heat recovery system for exhaust heat pump

Collection of waste heat: During the production process, the waste heat recovery system of the exhaust heat pump perceives the waste heat generated in the system through sensors or other equipment. This can come from exhaust gas, wastewater, waste heat, etc. in industrial production, which can be accurately identified and collected by the system.

Transfer of waste heat: Once the waste heat is collected, the system will transfer it to the exhaust heat pump system. During this process, pipelines or other thermal conductivity equipment are usually used to ensure that waste heat can be efficiently and quickly transported to the heat pump system.

Reuse of heat energy: After the waste heat is transported to the exhaust heat pump system, the heat energy in the waste heat is converted into higher temperature heat energy through stages such as compression and expansion during the heat pump cycle. This process achieves the regeneration and utilization of waste heat, improving the energy utilization efficiency of the entire system.
