Things to Know about GreenMango HVLS Fans

GreenMango Solutions HVLS fans

Perhaps most people very rarely take interest in fans. It is hard to blame. After all, as long as we have one to blow our hair in our faces, everything is well, right? How about if I tell you that you are wrong? What would you do if I tell you to have the choice to pick a better cooling fan, in terms of coverage, energy and cost efficiency?

The Efficiency

According to BigFanInstaller, ceiling fans are considered as one of the most effective types of fans. It is because they are effective in air circulation, creating a draft throughout the room. Also, when used with air conditioning, ceiling fans allow users to users to raise thermostat settings to about 4° Fahrenheit, and without compromising comfort.

BigFanInstaller added that studies by mechanical efficiency experts reveal that a type of ceiling fan, which is called High Volume Low Speed fan or HVLS fan, is the most energy-efficient air circulating fan available. Moreover, when used as a stand-alone cooling system, HVLS fans are able to provide a cooling effect equal to a reduction in the temperature of up 8° Fahrenheit within the fan’s coverage area of up to 20,000 sq. ft per 2 horsepower 24-foot fan.

The Energy

An HVLS fan is proven to save a huge amount of energy as it consumes relatively the same amount of electricity required by a high-speed fan while being able to move over 12 times the amount of air. A “downwash” feature was also enhanced, which increases airflow cubic foot per minute (CFM) by almost 30 percent with only minimal increase in power consumption.

Moreover, an HVLS fan saves on energy cost by increasing the thermostat temperature and at the same time maximizing the comfort level during hot periods or by warming the facility through destratification during the cold periods. Destratification is defined as a process in which the air or water is mixed in order to eliminate stratified layers of temperature. Therefore, these features surely save a significant amount of funds allotted to energy and heating bills, especially in larger facilities.

An HVLS fan is advantageous during hot periods as it acknowledges that air conditioning a large building can be really expensive and complex. Size, occupancy, loading docks, and large doors and windows make indoor climate difficult to control. Recirculating conditioned air allows the thermostat to be set higher during hot periods. But by using energy-efficient fans in conjunction with air conditioning, companies can raise thermostat set points to save up to 30 percent on cooling cost without compromising comfort. As an HVLS fan’s blades slowly rotate, they effectively move air at 3 to 5 miles per hour. this air movement is sufficient to break up the moisture-saturated boundary layer that surrounds our bodies. As sweat evaporates, a cooling effect is produced.

It is also advantageous during cold periods. During these times, stratified air forms temperature layers, with the coolest air at the floor and the warmest air trapped at the ceiling. This phenomenon is caused by the fact that warm air is approximately 5 percent to 7 percent lighter than cool air

Output Integrity

Condensation occurs when warm, moist air contacts a cold surface. During hot periods, temperature swings and the results of condensation can bring great damage to unconditioned workplace environments. This destroys inventories, as well as create possible hazards in the workplace, especially towards mechanical supplies and equipment. It is because excessive moisture and humidity can rust metal and even storage boxes. But, an HVLS fan can keep condensation from setting on the floor or the product.

On the other hand, cool, moist environments also encourage the growth of mold and mildew, which produces unpleasant odors. through providing well ventilation through efficient air circulation, an HVLS fan disperse cool, moist, stagnant air and its’ associated odors to ensure the cleanliness of facilities.

Whereas food products, especially produce and medicines can spoil or be damaged if stored with improper temperature control. To be able to prevent these, an HVLS fan can eliminate hot or cold zones from floor to ceiling that damages a product’s integrity. With this, spoilage and another damage cost will also be lessened.

Workers Health, Safety and Productivity

Everybody dreams of a healthy, safe and productive working environment. Since the workers are one of the main contributors behind a company’s success, it is just as important to provide them beneficial working conditions.

One of the ways to achieve this is to ensure that air needs to circulate efficiently throughout the facility. Proper air circulation eliminates pollutants which cause a variety of illnesses and other air-related concerns. HVLS fans provide air movement that dissipates stagnant air and mitigate poor air quality in order to provide greater comfort to workers. This will also be extremely beneficial to company owners, as financial loss from workers’ illnesses will be lessened.

Humidity is also a primary cause of SBS. Sick Building Syndrome (SBS) is used to describe instances where occupants experience health and comfort issues relatively linked to time spent in an area.

Furthermore, studies have shown that as temperature goes up, productivity drops, and even just a few degrees temperature difference can have a 5% or more degradation effect in terms of productivity.

Humidity plays a major role in the perception of heat in a building, and eliminating moisture is one of the best ways to create a healthy atmosphere comfortable enough for workers.

They are designed to withstand the pressure between the hub and the connectors, which substantially enhance speed and safety. They are also certified that the strength at the end of the hub is 10x more centrifugal force and stress generated by blade rotation.
