Whether it is a home or a building, ventilating homes in any climate can be a challenge. Consider the case of cities like Winnipeg, Stockholm, and Oslo; winters are extremely cold and the wind coming in can be extremely dry.
Then we consider cities like Phoenix, Mexico City, Cairo, Rabat, Algiers, Windhoek, and Tunis; the summers get quite hot and air conditioning costs rise. Santa Monica in California has a mild Mediterranean climate. When windows are painted like the house, they get stuck. Ventilating buildings and homes in humid climates is different.
Humidity can be annoying. People run their air conditioners in humid climates to reduce indoor humidity levels. Keeping the levels below 60% is recommended. This method would work on hot days and also on days that are not hot.
But when residents try to bring in outdoor air the amount of passive air indoors from other people is reduced. Wind outdoors is brought in to improve the air quality indoors, but in humid climates; water vapor and moisture is also introduced. This on a hot day is unacceptable and requires the air conditioner to get started. Otherwise, everything will feel sticky indoors.
Residents and engineers should understand proper methods for ventilating homes and buildings in humid climates and seasons. Construction claims professionals have decided to share with us some really good ways of ventilating homes and buildings in humid climates. They need to be done properly to ensure ventilation is top-notch.
Fans blowing in the air, out, or in both ways
Mechanical ventilation works quite well. It simply means moving air in and out, or in both ways by means of fans. A complete mechanical ventilation system for apartments, condos, and homes can easily move air in and out to help change the inner atmospheric and air conditions.
One of the easiest and most well-known ways of providing this kind of ventilation is running fans that exhaust air from the home, supply fresh air, or both. The same goes for individual units in apartments and condos.
A balanced system of ventilation using fans is worth the investment. It ventilates air inside and outside and balances its conditions too. A simple version may not be feasible for long-term ventilation of homes and other residential/commercial units. But it does have an advantage: it reduces pressure effects in buildings and homes. Somehow it does bring in humid air in the building.
Fans that supply air only with humidistat
Keeping positive pressure inside homes and buildings is preferred in humid climates. Thus the first improvement on a supply-only system is a humidistat. It helps residents and tenants set limits in upper and lower areas of humidity and temperature for their homes and residential units.
When the air outdoors is not within the required ranges, the fan closes and waits for the conditions to improve. It starts ventilating again when the conditions are good. The air supply can be directed to a duct and dumped in a return vent for further conditioning and distribution.
Central fan integrated supply system
The central fan integrated supply system comes with a controller and a duct connecting the return duct of central air management to the exterior. It also comes with an air-damping motor. Users can set the system up for as many minutes per hour as possible to help bring in conditioned outdoor air.
When the heating/cooling system is working, the damper works until it reaches its time limit. If the cooling/heating system isn’t running properly, the blower starts working. In turn, the damper turns on and ventilates the air until it reaches the required amount of ventilation.
A complete ventilating dehumidifying system
The Houston, New Orleans, Orlando, Tampa, and Miami metro areas can be quite wet, hot, and humid like Rio de Janeiro, Kuala Lumpur, Bangkok, Havana, Port of Spain, Belize City, Manila, and Bogota. Construction companies and architects usually specify a ventilating dehumidifying system in most HVAC designs.
Expert services professionals explain these systems extract air from outdoors and dehumidify them. The conditioned air is sent into the home/other residential or commercial unit. These systems are efficient and made in countries like the United States, Canada, Colombia, and Japan. They are built to last long and are also easy to fix.
The best way to set them up is by setting up independent ducts. They can be connected to heating and air conditioning systems when there is not much room for ductwork.
Over to you
Setting up ventilation systems in homes and buildings present in hot and humid climates is not easy but also not that hard. The climate of these countries is tricky and builders must ensure the health of residents is not adversely affected in any way possible. A humid and hot climate is a tricky climate and air conditioning becomes a necessity especially when the air has warmth and moisture in it.
