Morella is nearly 2,000 meters above sea level, with an average annual temperature of about 20℃. The humidity is relatively high from June to September. The following are some places suitable for installing ERV ventilation systems:

- ** Bedrooms and living rooms in residences ** : These are areas where people stay for long periods of time and have high requirements for air quality. The ERV ventilation system can provide fresh air while recovering the heat or cold from the exhaust air, maintaining a comfortable temperature and humidity indoors. The main unit can be installed in the equipment room or attic. The air inlet is set at a high position on the exterior wall, and the exhaust outlet is reasonably set in the corner or near the bathroom and kitchen according to the room layout.

- ** Hotel Guest rooms and public Areas ** : Hotels need to provide guests with a comfortable environment. The ERV ventilation system can effectively improve air quality, reduce odors, and keep the indoor air fresh. In guest rooms, the air outlets of the ventilation system can be combined with the air conditioning system. In public areas such as lobbies and restaurants, air outlets can be reasonably arranged based on the size of the space and the distribution of people flow to ensure even air circulation.

- ** Classrooms and offices in schools ** : Schools are densely populated and the air is prone to being polluted. The ERV ventilation system can introduce fresh air without affecting the indoor temperature, improve air quality, and be beneficial to the health of teachers and students as well as their learning and working efficiency. The main unit can be installed in the equipment room on the roof or at the end of the corridor, and the pipes are connected to each classroom and office through the ceiling or walls.

- ** Hospital wards, operating rooms and waiting areas ** : Hospitals have strict requirements for air quality and hygiene conditions. The ERV ventilation system can filter out bacteria, viruses and other pollutants in the air, and at the same time regulate humidity to prevent equipment from getting damp. The ERV main unit in the ward can be installed in the adjacent equipment room. The ventilation system in the operating room needs to adopt high-efficiency filtration equipment and be professionally designed according to the grade and function of the operating room.

- ** Office and retail areas in commercial buildings ** : In commercial buildings such as shopping malls and office buildings, there is a large flow of people. The ERV ventilation system can ensure the freshness and comfort of the indoor air, enhancing the experience of customers and employees. The main unit can be installed in the basement or on the roof of the machine room. Fresh air is delivered to various areas through pipes, and the exhaust vents are set near the sources of odors such as bathrooms and storage rooms.
