Depok is located in the West Java Province of Indonesia, in the southern part of the Jakarta metropolitan area. It has a tropical monsoon climate, with high temperatures and humidity throughout the year. The rainy season sees concentrated precipitation. As a satellite city with a concentration of universities and a combination of residential and industrial areas, it has a high building density and a large population movement. The ERV (Energy Recovery Ventilation) system can effectively balance temperature, humidity and energy consumption while ensuring indoor air quality. The following scenarios are particularly suitable for this system. 

High-rise apartments and gated residential communities are the core application scenarios of ERV. The newly-built high-rise apartments by Debao are mostly of sealed design. The windows are mostly fixed or have small opening slats, resulting in insufficient natural ventilation. Coupled with the dense population, indoor areas tend to accumulate CO₂, odors and moisture. In summer, the energy consumption of air conditioners is extremely high. The ERV system can continuously replace the air while recovering the energy from the exhaust air, reducing the load of air conditioning and filtering out pollutants such as PM2.5 and pollen. It is suitable for families with elderly members and children, as well as tenants who value a healthy living environment. During installation, a small ceiling-mounted ERV unit can be selected based on the ceiling space, adapting to the layout of the apartment and coordinating with the air conditioning system for control, thereby enhancing living comfort and saving energy. 

Large commercial complexes and office buildings have a prominent demand for ERV (Exhaust Air Recovery Ventilation). The shopping centers and office buildings in Debo mostly adopt closed central air conditioning systems. With dense populations and high equipment heat dissipation, indoor concentrations of VOCs and CO₂ tend to exceed the standards. Moreover, the long-term high-load operation of the air conditioning system increases operating costs. The ERV system recovers the cold and heat from the exhaust air through the full heat exchange core, reduces the cooling and heating loads of the air conditioning, stabilizes the supply of fresh air, improves office efficiency and reduces energy consumption. It is compatible with large ceiling-mounted ERV units and is linked with the central air conditioning system to meet the ventilation and energy-saving requirements of large areas, especially suitable for commercial landmarks such as ITC Depok and office clusters along Margonda Raya and Cinere Raya. 

Universities and research institutions are important application scenarios for ERV systems. Depok, as a hub for Indonesian universities, houses several institutions such as Indonesian University. The classrooms, laboratories, and libraries are densely populated and have high requirements for air quality and stable temperature and humidity. The ERV system can provide continuous fresh air, filter out bacteria and dust, recover energy to reduce operating costs, and the laboratory area can be customized with efficient filtration and air volume control to ensure the safety of the research environment. It can be adapted to ceiling-mounted or floor-standing ERV units, and the appropriate filtration grade can be selected based on the functional requirements of the place. 

Industrial buildings and storage facilities are highly compatible. The electronic and food processing plants in Debo have strict requirements for indoor temperature, humidity, and cleanliness. During production, heat, moisture, and pollutants are easily generated. Traditional ventilation methods often lead to energy waste and environmental fluctuations. The ERV system recovers energy when expelling polluted air, maintains stable temperature and humidity, reduces dehumidification and air conditioning energy consumption, and is suitable for electronic component workshops, food storage areas, etc. The floor-standing or ceiling-mounted units can be selected based on the size of the building, and the air volume and filtration grade can be customized to ensure a stable production environment. 

Medical and educational institutions are equipped with ERV systems to enhance environmental safety. The places such as hospitals, clinics, and schools in Debao have high personnel mobility, which makes cross-infection likely and requires ensuring fresh and comfortable air. The ERV system continuously supplies fresh air, filters out bacteria and dust in the air, and simultaneously recovers energy to reduce operating costs.ERV units with high-efficiency filtration functions can be installed in areas such as hospital wards, operating rooms, school classrooms, and laboratories to improve indoor environmental safety and ensure the health of patients, doctors, and teachers and students. 

Hotels and dining establishments can enhance service quality and energy-saving efficiency through ERV systems. The hotel rooms, restaurants, and kitchen areas of Debao are densely populated, prone to odors, fumes, and moisture. Traditional ventilation methods often lead to energy waste and poor environmental conditions. The ERV system effectively removes odors and moisture, recovers the energy from the exhaust air to reduce air conditioning energy consumption. The kitchen area can be equipped with a dedicated exhaust system, combined with the ERV unit to improve ventilation efficiency and reduce the impact on the surrounding environment. Hotel rooms can use wall-mounted or small ceiling-mounted units, while restaurants and kitchens should select appropriate air volume units based on the size of the space, taking into account both service experience and operating costs.
