Cimahi is located in West Java Province of Indonesia. It is the core satellite city of Bandung and is situated in a volcanic plateau area. It has a tropical rainforest climate, with high temperatures and humidity throughout the year. The average humidity exceeds 80%, and there is abundant precipitation with afternoon thunderstorms. The city is close to Bandung and has absorbed some industrial and population outflows. The building density is high, and surrounded by mountainous rainforests, the air contains high levels of moisture, pollen, and mold spores. Industrial production also brings a small amount of fine particulate matter. Indoors, problems such as stale air, excessive humidity, and mold growth are prone to occur. Although the temperature in Cimahi is slightly cooler than that of plain cities, the environment of high humidity and industrial dust makes the ventilation and air quality issues of sealed buildings particularly prominent. The ERV (Energy Recovery Ventilation System) can continuously ventilate and exchange air while efficiently recovering the coldness and humidity from the exhaust air, reducing the energy consumption for dehumidification and cooling, and also through multiple levels of filtration, it can intercept pollen, industrial particles, and microorganisms from outside, precisely balancing the indoor temperature and humidity, fundamentally improving indoor air quality. This is crucial for enhancing the environmental comfort and operational efficiency of various places. The following places are particularly suitable for installing ERV systems:
The various residences in Cimahi are the core application scenarios for the ERV system. Whether it is multi-story apartments in the urban area, workers' residential communities, or single-family houses in the suburbs, they can significantly improve the living experience by using the ERV system. As a satellite city of Bandung, the residences in Cimahi mainly serve people working in Bandung and local industrial zones. These residences are mostly modern sealed buildings, designed to isolate outdoor high temperatures, industrial noise, and dust. Residents often close the windows and rely on air conditioners, which easily leads to poor indoor air circulation, increased carbon dioxide concentration, and mold growth. The high humidity environment also causes walls, furniture, and clothes to mold, and industrial fine particles can penetrate into the indoor area, affecting the respiratory health of residents. The ERV system can introduce fresh outdoor air continuously without opening windows, effectively intercepting industrial particles, pollen, and mold spores, removing the stale air and excess moisture from the indoor area, and recovering the coldness from the exhaust air, reducing the operating load of air conditioners, and controlling indoor humidity within an appropriate range. This creates a dry, fresh, and quiet living environment for the working class, especially suitable for families with elderly, children, and those with respiratory sensitivities, as well as residences near industrial zones and prone to dust pollution.
