Fresh, clean air is essential to good health. However, mold, condensation, and other issues that can have serious consequences for the structure of your home and for the health of its occupants.Heat recovery ventilator ( also called fresh air system) and air purifiers are useful "weapons" to solve the problem of home air quality. The Basic Principle The heat recovery ventilator is an air circulation treatment system consisting of a ventilator, a pipeline, etc. The main function is to filter and purify the outdoor fresh air into the room through the pipeline, while diluting the indoor carbon dioxide content and increasing the indoor oxygen content, and Indoor dirty air is discharged outside to keep indoor air fresh. The air purifier...
Proper air circulation and ventilation are crucial in any home, because airflow regulates temperature, removes impurities, prevents mold and just creates a more pleasant and safe breathing environment. Poor indoor air circulation isn't just annoying. It can lead to health concerns, and even worsen the effects of asthma. There are steps you can take to improve indoor air circulation. 1. Open Doors and Windows This is the most simple and obvious way to immediately improve the indoor air circulation. By simply opening windows in different rooms, you can create a cross flow that improves the circulation of the entire house. 2. Install Exhaust Fans Install exhaust fans, especially in the kitchen and bathroom. An exhaust fan works sort of like...
DC Fans (direct current fans)The DC fans are powered with a potential of fixed value such as the voltage of a battery. Typical voltage values for DC fans are, 5V, 12V, 24V and 48V. AC Fans (alternating current fans)The AC fans are powered with a changing voltage of positive and of equal negative value. In general, this changing voltage has sinusoidal shape. Worldwide, the usual value of this sinusoidal voltage may vary in size and in frequency, such as 100V, 120V, 200V, 220V, 230V or 240V, and with frequency (cycles per second) of 50Hz or 60Hz. EC Fans (electronically commutated fans)The EC fans use AC voltage too, but they can have a wider voltage range. They accept a supply...
