South Carolina has a subtropical climate, characterized by long, hot, and humid summers 

and short, cold, and dry winters, with abundant rainfall in many areas. ERV ventilation 

systems can recover energy to reduce energy consumption, regulate humidity, and purify the 

air, making them well-suited to the state's climate. They are particularly suitable for 

enclosed spaces or locations with high air quality requirements, such as residences, medical 

facilities, offices, and educational institutions. Specifically:

1. **Various Types of Residences**

Modern newly built homes in South Carolina are typically highly airtight for energy efficiency.

 In summer, the humidity can easily lead to mold growth and unpleasant odors, while in 

winter, the enclosed environment can result in poor air quality. ERV systems can pre-cool 

and dehumidify fresh air in summer and recover heat and moisture from the indoor air in 

winter, preventing excessive dryness. In cities like Charleston and Greenville, installing this 

system in detached houses and apartment buildings can improve indoor air quality, reduce 

energy consumption for air conditioning and heating, and lower living costs.

2. **Medical Facilities**

Hospitals and emergency centers have stringent air quality requirements. South Carolina has

 many high-tech medical centers, some of which have fresh air intakes located near 

emergency helicopter landing pads. Helicopter landings generate pollutants such as sulfur 

dioxide and volatile organic compounds. ERV systems, equipped with high-efficiency filters, 

effectively filter these gaseous pollutants, as well as airborne germs and particulate matter, 

while maintaining constant temperature and humidity. This provides a stable and clean 

environment for critical areas such as operating rooms and emergency rooms, ensuring 

smooth patient recovery and medical work.

3. **Office and Commercial Buildings**

Office buildings, shopping malls, and hotels in cities like Columbia and Hilton Head Island are

 typically densely populated and highly enclosed. Prolonged use can lead to increased 

carbon dioxide concentrations and air pollution. ERV systems can continuously deliver fresh 

air while recovering energy, reducing the load on central air conditioning systems. For 

example, in Hilton Head Island, a popular tourist destination, local resorts installing this 

system provide guests with a comfortable stay and enhance the hotel's reputation.

4. **Schools and Educational Institutions**

Throughout the state, primary and secondary schools, universities, and other campuses often

 have densely populated classrooms and dormitories, where students tend to have relatively 

weaker immune systems. The state's humid summers can easily breed bacteria in enclosed 

classrooms, while winter heating can dry out the air. ERV systems ensure air circulation in 

classrooms, filter allergens and pollutants, and balance indoor temperature and humidity, 

creating a healthy learning and working environment for students and faculty. This is a 

suitable scenario for classroom buildings and dormitories at the University of South Carolina.

5. **Industrial and Research Sites**

Some areas of the state have manufacturing plants and research laboratories. For example, 

chemical-related research institutions or small manufacturing workshops around the 

Savannah River may produce small amounts of harmful gases, and the production process 

has certain requirements for indoor temperature and humidity. ERV systems can exhaust 

stale indoor air, introduce fresh air, recover energy to reduce production energy consumption,

 and reduce the probability of outdoor pollutants entering the room through filtration 

systems, ensuring research accuracy and worker occupational health.
