Focus on EC fan only
Black King Series products ia high efficiency fans.It will give you a new feeling in the ventilation area.
There are two general classifications of fans: the propeller or axial flow fan and the centrifugal or radial flow fan. In the broadest sense, what sets them apart is how the air passes through the impeller.
Cooling systems play an increasingly critical role in protecting sensitive IT systems from extreme variations in temperature and humidity that can cause system failure, degrade performance, and shorten equipment life--particularly in the high-density environments that have become common in enterprise data centers.
Refrigeration processes are very common and have significantly improved life quality of many people. And with improvement of life quality, people seek higher standard for refrigeration devices-energy saving. To maximize the time the compressor and condenser can be off without sacrificing the temperature of your refrigerator, consider retrofitting your current evaporator fan motor with an Electronically Commutated Motor (EC motor) with a controller.
Refrigeration is a process of moving heat from one location to another in controlled conditions. In the refrigeration cycle, there are five basic components: fluid refrigerant; a compressor, which controls the flow of refrigerant; the condenser coils; the evaporator coils; and something called an ex
Ventilation is the intentional introduction of outside air into a space. The general purpose of ventilation in buildings is to provide healthy air for breathing by both diluting the pollutants originating in the building and removing the pollutants from it. Building ventilation has three basic eleme
A household appliance is an electrical/mechanical machine which accomplish some household functions, such as cooling/heating , cooking or cleaning. Common household appliances like air conditioner, refrigerator, vacuum cleaner, hand dryer, electric water heater tank, kitchen ventilator, air purifier
Split air conditioner is very common in daily life. A split air conditioner consists of two main parts: the outdoor unit and the indoor unit.The outdoor unit is responsible for cooling or heating, while the indoor unit takes charge of delivering the cold air or hot air inside door, and bringing the
As you know, FFU=Fan filter unitThe interpretation of the wikipedia as follows :A fan filter unit is a type of motorized air filtering equipment. it is used to supply purified air to cleanrooms, laboratories, medical facilities or microenvironments by removing harmful airborne particles from recircu
About Natural Ventilation Natural ventilation is the uncontrolled air movement in and out of the cracks and small holes in a home. In the past, this air leakage usually diluted air pollutants enough to maintain adequate indoor air quality. Today, we are sealing those cracks and holes to make our hom
The decision to use whole-house ventilation is typically motivated by concerns that natural ventilation won't provide adequate air quality, even with source control by spot ventilation. Whole-house ventilation systems provide controlled, uniform ventilation throughout a house. These systems use one
Ventilation for cooling is the least expensive and most energy-efficient way to cool buildings. Ventilation works best when combined with techniques to avoid heat buildup in your home. In some climates, natural ventilation is sufficient to keep the house comfortable, although it usually needs to be
