Victoria, Canada, has a Marine climate with a mild and humid climate throughout the year and heavy winter precipitation. Tourism is its core industry, and it is also home to shipbuilding, wood processing and many other industries, as well as numerous educational and government institutions. The ERV ventilation system can solve the dampness problem caused by high humidity, and also recover energy to reduce energy consumption. It is suitable for various local scenarios. The specific suitable areas and places are as follows

1. Dense residential areas in the core urban area

Victoria has a population of approximately 320,000. As the largest city on Vancouver Island, apartment buildings and single-family houses are densely distributed in the urban area. The local humidity is relatively high throughout the year, with abundant precipitation in winter. Moreover, doors and Windows are often tightly closed indoors to prevent dampness and rain, which makes it easy for mold to grow and for a damp and unpleasant smell to occur. The ERV system can efficiently expel the damp air indoors, introduce treated fresh air, and recover the energy of indoor temperature at the same time, reducing the energy consumption for heating in winter and cooling in summer. It is particularly suitable for these residential areas, ensuring the comfort of residents' living.

2. ** Popular cultural tourism and commercial venues **

The city is rich in cultural and tourism resources. Scenic spots such as Buchatte Garden, which is known as the "world's most beautiful Garden", the Emperor and Empress Hotel, and Craig Darok Castle are always crowded with tourists throughout the year. There is also Victoria's Chinatown, the oldest in Canada, which is home to a large number of restaurants and shops and has a huge flow of people. In addition, the commercial streets and various characteristic shops around the inner port are also densely populated areas. These places have a high demand for air circulation. The ERV system can not only quickly replace the air, avoiding air pollution caused by dense crowds, but also reduce the energy consumption of air conditioning and ventilation, which meets the cost control requirements for the long-term operation of commercial and cultural tourism places.

3. Industrial production site

Victoria's industry is centered on shipbuilding, ship repair and wood processing. In Esquimolt Bay in the western suburbs, there is a naval shipyard with one of the world's largest dry docks. There are also many wood processing plants and yacht manufacturing plants in the urban area. Shipbuilding and ship repair workshops may generate damp water vapor due to contact with seawater, and may also be accompanied by oil stains and unpleasant odors. Wood processing plants are prone to problems such as wood shavings and dust, as well as damp and moldy wood. The ERV system can achieve air circulation and replacement within the workshop, filter out some dust and odors, and recover energy at the same time, reducing the energy consumption for dehumidification and temperature control in the workshop and improving the working environment for workers. In addition, local fish product processing sites can also use this system to solve the problems of fishy smell and dampness generated during processing.

4. Government and educational and scientific institutions

In terms of government agencies, the British Columbia Parliament Building in the city center, as a landmark structure, has a large number of office workers on a daily basis and frequently receives visitors. It is necessary to maintain fresh indoor air and stable temperature and humidity. The ERV system can ensure ventilation while maintaining a stable indoor environment, meeting the usage requirements of such public buildings. In the field of science and education, there are many colleges and research institutions in the city. Moreover, the regional science and technology industry has become the largest private revenue-generating industry. Relevant research laboratories, classrooms of colleges and universities, libraries and other places have long periods of personnel stay. Some laboratories also produce slight experimental exhaust gas. The ERV system can efficiently purify the air, replace ventilation, and at the same time reduce the energy consumption of research and teaching places.

5. ** Port and naval related areas **

Victoria has two deep-water ports: the urban commercial port and the suburban naval base. The urban commercial port, as an ice-free port, undertakes domestic and overseas trade tasks. The cargo dispatching room and storage area of the port have frequent personnel flow, and the Marine environment makes the air humid, which is prone to causing goods to get damp. The Canadian Navy Pacific Fleet Command is stationed at the naval base in the suburbs. The relevant office and duty areas need to maintain a suitable indoor environment for a long time. The ERV system can cope with Marine humid climates, providing stable ventilation and temperature and humidity control for various places such as port warehouses, office areas, and naval bases, while recovering energy to reduce operating costs.
