Understanding how heat is transferred from outdoors to indoors, and from home to your body is important to keep your indoor space cool. Learning the process of keeping your body cool is important to understand the cooling strategies for your home.

As a leading ceiling fans manufacturer, we share with you a few principles of cooling the human body:

Principles of cooling

Cooling the human body

There are three processes to cool down the human body: convection, radiation and perspiration. All of these processes are enhanced by ventilation.

1. Convection: If the surrounding air around you is cooler than your skin, it will absorb your heat and rise above. As the warm air rises above, cooler air takes its place and absorbs more of the heat. The faster this process moves, the cooler you feel.
2. Radiation: This process happens when the heat radiates between you and the other objects in your interior space. If these objects are warmer than your body, the heat will move towards you. You can control the temperature of your surroundings such as the ceiling, walls and furnishing by ventilation.
3. Perspiration: Although it can be uncomfortable to many, perspiration or sweating is a powerful cooling mechanism for your body during hot weather and physical exercise. As moisture from your body leaves your skin pores, it carries out a lot of heat with it, leaving your body cool. The moisture will evaporate more quickly if a breeze passes over your body - this will leave you feeling cooler.

How does heat accumulate in homes?

Heat accumulates in homes through several sources. This heat can further make indoor temperatures higher than outdoors. The major source of indoor heat in most climates is sunlight that enters a home mostly through the roof and windows. Other sources of heat include

• Lighting solutions (particularly incandescent and halogen lighting)
• Dishwashers
• Televisions
• Refrigerators.

How to prevent heat from entering or accumulating in your home?

• Install additional attic insulation
• Sun-blocking windows
• Put shades or blinds in a room
• Install window awning

Some of the operational changes you can carry out are:

• Reduce the use of electrical appliances
• Avoid using light-emitting bulbs like incandescent light bulbs
• Let the night air in. Keep your doors and windows open at night
• Keep all the doors inside your home open for better circulation of air
• Use exhaust fans in your kitchen and washrooms to push out the extra moisture and heat
• Install a good ceiling fan. Set your ceiling fans to rotate counter-clockwise. By reversing the spin, the fan will pull warm air up and push the cooler air towards you.
