Facts About Solar Home Air Conditioning
Solar home air conditioning can help you stay cool in the hot summer months without hiking electricity bills. It is a lesser known solar energy application which has great potential for widespread use. Though it may sound like a contradiction, a solar air conditioner utilizes the energy from the sun to cool a home. The solar air conditioners are of great benefits especially for people who live in arid areas where there is abundant sunlight.
The solar home air conditioning systems are either active or passive. Active solar air conditioners are further found in two types which include solar absorption coolers and solar desiccant coolers. The solar absorption coolers usually absorb heat using thermal collectors. The absorbed heat is then used for separating a mixture of refrigerant fluids from absorbent fluids. The refrigerant fluids are then condensed and evaporated causing the air to be cool. The cold air goes to the house, and the absorbent fluids reabsorb the fluid, and the cycle is repeated.
The process for solar desiccant coolers is different. Moist air is passed over a desiccant wheel that has a mixture of trapping materials which absorb it and make the air cool. The cool air is then sent out into the room using fans. The desiccant coolers require lesser temperature compared to absorption coolers.
The second type of solar home air conditioning systems, passive solar air conditioners, is usually designed along with the house. They are usually built as solar chimneys or solar cooling towers. The solar chimney is strategically positioned on the house so that it can absorb sun’s heat effectively. It is then connected to the inside part of the house together with a high point vent on one side and a low point vent on another side. The low point vents are connected to underground pipes.
When air in the passive air conditioner is heated up the chimney, an upward draft that creates a vacuum is created. The vacuum causes air to be drawn into the low point vent where it is cooled by the water pipes. The cool air is then released into the house for cooling, and the process repeats itself.
Solar home air conditioning systems have several advantages. They are eco-friendly, implying that no non-renewable energy sources are depleted by using them. The systems rely on solar energy which is one of most abundant energy sources. Cooling the interiors of the houses is facilitated by the solar energy as well as air and water. There is no emission of greenhouse gases such as carbon monoxide and carbon dioxide.
Setting up the solar home air conditioning systems is less costly. This method will also help you to cut down on your electricity bill since it does not need backing from electricity to operate. You can use it anytime despite load shedding. The solar air conditioners are effective and can be used for residential, industrial, commercial, governmental as well as military purposes.
