Cooling a Room with Chilled Water and a Fan-Motor Assembly
What is the purpose of circulating chilled water through a heat exchanger in a room?
Is the air circulated through the heat exchanger by a 0.25-hp fan?
What is the typical efficiency of small electric motors driving 0.25-hp equipment?
By circulating chilled water through a heat exchanger in a room, the purpose is to cool the room effectively and efficiently. This method helps in maintaining a comfortable temperature indoors without consuming too much energy.
Yes, the air is indeed circulated through the heat exchanger by a 0.25-hp fan. This fan helps in distributing the cool air generated by the chilled water throughout the room.
The typical efficiency of small electric motors driving 0.25-hp equipment is 60 percent. This means that 60 percent of the energy input is converted into useful work output, while the remaining 40 percent is lost as heat.
When it comes to cooling a room, using chilled water along with a fan-motor assembly can be a cost-effective and energy-efficient solution. By circulating the chilled water through a heat exchanger in the room, the heat from the indoor air is absorbed by the water, resulting in a cooling effect. The fan, powered by a 0.25-hp motor, helps in moving the air through the heat exchanger, distributing the cool air into the room.
The typical efficiency of small electric motors driving 0.25-hp equipment is 60 percent, indicating that these motors can convert 60 percent of the energy input into useful work output. This efficiency factor is crucial in determining the overall performance and energy consumption of the fan-motor assembly.
In conclusion, by understanding the purpose of circulating chilled water, the role of the fan-motor assembly, and the typical efficiency of the electric motors involved, we can create an effective cooling system for indoor spaces while optimizing energy usage.
