1. Core Applications of Compressoe in Heat Pumps and Heat Recovery Fields

Compressors serve as the core energy conversion component in heat pump and heat recovery systems, realizing the upgrading and recycling of low-grade thermal energy through the compression of working fluids (such as steam, refrigerant). Their typical applications are as follows: steam refrigerant). Their typical applications are as follows:

1.1 Heat Pump System

Industrial Heat Pumps: Centrifugal, Screw, or roots-type compressors are used to upgrade low-grade waste heat (e.g., 30-80℃ industrial wastewater, flue gas waste heat) into high-temperature heat sources(100-180℃）for process heating, drying, and distillation in chemical, pharmaceutical, and food industries. This reduces reliance on fossil fuel boilers.

Building Energy-Saving Heat Pumps:

Scoll or rotary compressors are applied  in air source, ground source, and water source heat pumps for building heating and cooling, replacing traditional electric heating and split air conditioners to improve energy efficiency.

1.2 Heat Recovery Systems

MVR Evaporation Systems: Roots or centrifugal steam compressors compress secondary steam generated during evaporaiton into high-temperature, high pressure heating steam, which is recycled for material heating. This technology achieves near-zero fresh steam comsumption and is widely used in wastewater treatment, brine concentration, and chemical crystallization processes.

Industrial Waste Heat Recovery Units: Compressors are intergrated with heat exchangers to recover waste heat from flue gas, cooling water, and process tail gas in steel, non-ferrous metal, and cement industries. The recovered heat is used for preheating raw materials or supplying domestic hot water, improving overall energy utilization efficiency of enterprises.

2. Environmental Impacts

The application of compressors in heat pump and heat recovery systems directly addresses the core envirnomental concerns of  foreign enterprises, including carbon neutrality, resource conservation, and pollution reduction.

2.1 Carbon Emission Reduction

Energy Efficiency Improvement: Heat pump systems driven by compressors have a COP (Coefficient of performance) of 3-8, far higher than electric heating (COP=1) and traditional boilers heating (efficiency generally 70%-90%). For example, an MVR evaporation system can save 60%-90% of steam compared to multi-effect evaporation, reduing indirect carbon.

emissions from fossil fuel combustion.

 2.2 Resource Consetvation

Water Resource Saving: MVR systems reduce the consumption of fresh steam and cooling water, avoiding large-scale discharge of condensed water. In high-water-consumption industries such as chemical and wastewater treatment, this can reduce water consumption by 30%-50%.

Waste Heat Valorization: Converting originally discarded low-grade heat into usable energy reduces the demand for primary energy (coal, natural gas) alleviating resource depletion pressure.

2.3 Pollution Reduction

Air Pollution Control: Replacing coal-fired and oil-fired boilers with heat pump systems reduces emissions of sulfur dioxide, nitrogen oxides, and particulate matter, improving regional air quality and complying with strict environmental emission standards of foreign enterprises.

Wastewater Treatment: MVR systems realize concentrated treatment of high-salt and high-organic wastewater, reducinb the environmental risk of wastewater discharge and aligning with the circular economy concept.

3. Social  Impacts

The popularization of compressor-based heat pump and heat recovery technologies brings positive social benefits, as employee well-being, community development, and sustainable development.

3.1 Employee Health and Safety

Work Environment Improvement: Replacing traditional boilers with heat pump systems eliminates potential safety hazards such as boiler explosions and gas leaks, reducing occupational safety risks for employees.

Reduction of Occuptional Hazards: Reducing the use of fossil fuels lowers the concentration of harmful gases and dust in workshops, improving the working environment and reducing the incidence of occupational diseases among employees.

3.2 Community and Regional Development

Energy Cost Reduction for Enterprises: Lower energy consumotion reduces production costs of enterprises, enabling them to have more funds for technological research and development and employee welfare improvement, driving local economic development.

Alleviation of Energy Supply Pressure: Improving energy utilization efficiency reduces the demand for regional power and fossil energy, ensuring the stability of energy supply for residents and reducing the impact of energy shortages on community life.

Promotion of Green Employment: The popularzation of heat pump and heat recovery technologies drives the development of related industries such as compressor manufacturing, system integration, and operation and maintenance, creating new green employment opportunities and promoting local employment.

3.3 Global Sustainable Development

Promotion of Low-Carbon Industrial Transformation: As a core technology of energy conservation and emission reduction, it provides a feasible path for global high-energy consumption industries to achieve low-carbon transformation, responding to the global climate change challenge.

Technology Popularzation and Capacity Building:

Foreign enterprises can promote the global climate change challenge.

Technology Popularization and Capacity Building:

Foreign enterprises can promoto the global application of this technlogy through technology tranfer and local cooperation, helping developing regions improve energy efficiency and achieve balanced development of economic growth and environmental protection.

4. Alignment with core Values of Foreign Enterprises

ESG Governance: The environmental benefits （carbon emission reduction, resource conservation) and social benefits (employee safety, community development) brought by the technology are directly reflected in the ESG performance of enterprises, meeting the investment expectations of shareholders and the supervision requirements of the society.

Sustainable Development Strategy: The technology helps enterprises reduce thrie dependence on non-renewable energy, improve the stability of the supply chain, and achieve long-term sustainable operation of the enterprise.

Stakeholder Responsibility: It meets the environmental demands of governments, communities, and consumers, enhances the brand image and social reputation of enterprises, and realizes the balanced development of enterprise interests and stakeholder interests.
