Chayapala is located in Papua Province, Indonesia, in the northern part of New Guinea Island.

 It has a tropical rainforest climate with high temperatures and humidity throughout the year and 

abundant precipitation. Moreover, the surrounding areas of the city are mostly mountainous rainforests, 

with a high concentration of water vapor, pollen and mosquito-breeding microorganisms in the air. 

At the same time, some areas within the city have relatively dense infrastructure, and the problem of 

indoor air pollution caused by human activities is also quite prominent. ERV (Energy Recovery Ventilation System) 

can continuously ventilate and exchange air while efficiently recovering the coldness and humidity in the exhaust air, 

reducing the energy consumption of air conditioning dehumidification and cooling. It can also intercept outdoor 

particulate matter, pollen and other pollutants through its filtration function, balance indoor temperature and humidity, 

and prevent mold growth. It is particularly crucial for improving indoor air quality and living and working comfort in various places. 

The following places are particularly suitable for installation:

The residences in Chayapura, especially modern sealed houses and high-rise apartments, are important 

application scenarios for ERV systems. The local climate of high temperature and humidity throughout the

 year makes residents rely on air conditioners for cooling and dehumidification for a long time. The state 

of tightly closed doors and Windows easily leads to poor indoor air circulation and an increase in carbon 

dioxide concentration. At the same time, the humid environment is prone to cause mold on walls and furniture, 

and even breed harmful microorganisms. The ERV system can continuously introduce filtered fresh outdoor air 

and expel the stale indoor air without opening the Windows. At the same time, it recovers the coldness and 

humidity in the exhaust air, reducing the operating load of the air conditioner. This not only lowers energy 

consumption costs but also effectively controls indoor humidity and prevents mold growth, creating a dry 

and fresh living environment for residents It is especially suitable for families with the elderly, children and 

people with sensitive respiratory tracts.

As the capital of Papua Province, Jayapura is home to a large number of government office buildings, corporate office 

Spaces and business office buildings. These commercial office buildings are densely populated and usually have air 

conditioners running all day long. The indoor air is prone to become dirty due to people's breathing and the heat 

dissipation of office equipment. Excessive carbon dioxide concentration can also affect the work efficiency of employees. 

The ERV system can continuously supply fresh air to the office area, diluting harmful gases and odors indoors. 

At the same time, through its energy recovery function, it reduces the energy consumption required by air conditioners to 

maintain indoor temperature. While ensuring the physical health of office workers and improving work efficiency, it also 

lowers the operating costs of buildings, meeting the demands of green offices. Whether it is an open office area or an 

independent office, Whether it is public office areas such as meeting rooms and reception areas, they can all play a significant role.

Jayapura, as an important medical center in eastern Indonesia, has many hospitals, clinics and community health centers. These 

medical facilities have extremely high requirements for indoor air quality. They not only need to ensure an adequate supply of fresh air, 

but also prevent cross-infection of bacteria, and maintain a stable temperature and humidity environment to facilitate patients' recovery. 

The multi-stage filtration function of the ERV system can effectively intercept pollen, particulate matter and harmful microorganisms in 

outdoor air, delivering clean fresh air to areas such as wards, operating rooms and examination rooms, while expelling indoor bacteria 

and stale air, reducing the risk of cross-infection. Its energy recovery feature can also maintain the stability of indoor temperature and 

humidity while ventilating, avoiding the impact of sharp fluctuations in temperature and humidity on the recovery of patients' conditions. 

It also provides a healthy and comfortable working environment for medical staff, making it an important choice for medical facilities to 

improve air quality and operational efficiency.

Tourism is one of the important industries in Chayapura. There are numerous hotels, homestays and resorts scattered throughout the city. 

Such accommodation facilities need to provide tourists with high-quality living experiences, and indoor air quality and living comfort are 

the key factors affecting tourists' satisfaction. Due to the local hot and humid climate, if the ventilation is poor, hotel rooms are prone to 

dampness and mold, which will affect the accommodation experience of tourists. The ERV system can continuously introduce fresh air into 

areas such as hotel rooms, lobbies, restaurants, and leisure zones, filter outdoor pollutants, and recover energy to reduce air conditioning 

energy consumption. This not only enables guests to enjoy a dry and fresh indoor environment during their stay, enhancing their accommodation 

experience and hotel reputation, but also helps hotels save operating costs. It is especially suitable for mid-to-high-end hotels and homestay 

resorts that emphasize ecological and health concepts.

Schools, kindergartens and other educational institutions in Chayapura are also key areas where the ERV system is applicable. The classrooms, 

dormitories and other areas within the school are highly crowded with people. Students' immunity is relatively weak, and there are many pollen 

and microorganisms carried by mosquitoes in the local air, which can easily lead to the spread of respiratory diseases. During winter 

(the relatively cooler season in the local area) and the hot summer, schools usually close doors and Windows and turn on air conditioners, 

making the problem of poor indoor air circulation more prominent. The ERV system can continuously supply fresh air to areas such as classrooms, 

libraries, and dormitories, dilute carbon dioxide and bacteria indoors, reduce the probability of disease transmission, and at the same time filter 

pollutants outdoors to protect students' respiratory health. Its energy recovery function can also reduce the energy consumption of school air conditioners, 

alleviate the pressure of school operation costs, and create a healthy and comfortable learning and living environment for students.

In addition, crowded public venues such as shopping malls, supermarkets and stadiums in Chayapura, as well as production sites such as food processing 

plants and small industrial plants, are also suitable for installing ERV systems. Public venues have a large flow of people and the air is prone to being polluted. 

The ERV system can ensure the freshness of the air inside the venues and enhance the experience of citizens and tourists. The production site can filter 

outdoor pollutants through the ERV system to prevent them from entering the production area and affecting product quality. At the same time, energy 

can be recovered to reduce energy consumption during the production process, taking into account both production safety and operational efficiency.
