Air balancing is a fundamental design skill for HVAC engineers and consultants. Depending on the intended purpose of each building area, it may require negative, positive or neutral pressurization. This is accomplished by adjusting supply and exhaust airflows: a higher air supply causes positive pressure, while a higher air exhaust causes negative pressure. Although the ideal scenario would be to ventilate all building areas naturally, this is not possible in practice. For example, there is no way to use natural ventilation in areas that are completely surrounded by other rooms, as well as in underground levels. The purpose of ventilation can range from human comfort to facility safety: ventilation in residential and commercial settings is focused on delivering air of breathable quality, while industrial ventilation is often deployed to keep dangerous gases away from certain areas or below a certain concentration.

Our Ventilation series products include energy recovery ventilator(ERV), heat recovery ventilator(HRV) and some single ventilator (without heat recovery core). As for HRV and ERV, its function are not only as common exhausting fan but also a fresh air ventilation system. It helps to exhaust stale, damp indoor air and supply fresh, filtered air from outside, thus ensuring optimal indoor air quality and comfortable living. And the two air streams "meet" in the air-to-air exchanger core, the fresh air will be pre-cooled or pre-warmed by the stale air, thus saving your energy bills significantly. The systems are suitable for both retrofit and new construction project.

Residential ERV/HRV is whole house ventilation with heat recovery. You can also call it whole house air exchanger or whole house fresh air system. Constant fresh air in your home is an important aspect to maintain the indoor air quality. A good ventilation system will protect your family from unpleasant odors and harmful contaminants such as formaldehyde and VOCs. Opening window is a simply way to increase ventilation, it can make your air feel less stuffy, but pollen and other allergens will be invited into your home at the same time.

For humidity control device series, we have ventilating dehumidifier and central dehumidifier. Ventilating dehumidifiers are whole house ventilating dehumidifiers that can not only allow you to precisely control the indoor humidity levels of your entire house, but also provide you with fresh and filtered air at the same time. By reducing humidity levels within your home, you can reduce condensation, damp and mould problems. And with fresh air, you have abundant oxygen in your house.

Proper ventilation plays a crucial role in maintaining a healthy and comfortable living environment in your home. It allows fresh air to circulate while removing stale air, odors, and potentially harmful contaminants. Without adequate ventilation, the air inside your home can become stagnant and polluted, negatively impacting both your health and the overall quality of your indoor environment.

Soffit plays a crucial role in home ventilation systems, ensuring proper airflow and temperature regulation. Located on the underside of the roof overhang, the soffit acts as a ventilated barrier between the roofline and the attic space.

An Indian kitchen design requires proper ventilation, good floor space and should be traditional looking. For this, get in mind the two essential principles like form and functionality. These were some rules to follow when you wish to revamp your kitchen design into a modular kitchen.

Commercial ERV/HRV has bigger airflow type than residential ones, widely used in large commercial buildings and industrial applications, such as office buildings, hotel, theater, Hospitals, labs, confinement center, school, bank, etc. It's also balanced ventilation system which use both an exhaust air blower and a supply fan that does not pressurize a building. Stale room air is exhausted and fresh outdoor air is brought into the structure. And there is air-to-air heat exchanger that is designed to transfer heat and sometimes moisture between two air streams. They improve the indoor air quality and reduce the load on air handling units to be more energy saving and efficient.

Constant temperature and humidity air conditioning unit is an integrated system which maintain requested IAQ as a whole. For precision air conditioning units, they can control the humidity levels and temperature range very precisely. Mainly used for computer rooms and database room. For swimming pool dehumidifier and air conditioner, they can manage the swimming pool humidity, air temperature and even water temperature. For wine cellar climate control systems, they can always maintain the humidity and temperature to a best suitable degree. For passive house ventilating dehumidifier and air conditioners, they are mainly for the energy-efficient construction with good sealing, such as passive house. These constant temperature and humidity control system devices can not only control humidity and temperature but also bring in fresh air and exhaust stale indoor air. What's more, there are air-to-air heat exchanger core inside, thus can preserve most energy from the stale air
