The sun’s power can be used in many different ways and one of them is through solar heating systems. This systems goes through the processes that converts solar energy to heat. Heat can be produced through the use of solar thermal collectors which have three types. These are low, medium and high-temperature collectors.
The low-temperature collector, are flat plates that are used in heating swimming pools and even for heating and ventilation. The medium-temperature collector are also made of flat plates that are used for the purpose of heating air or water for homes and business establishments. The third-type which is the high-temperature collector do not use flat plates, instead, it uses mirrors and lenses that concentrates the solar power harnessing. The high-temperature collector is used to generate electricity. It is important to note that thermal collectors are different from photovoltaics.
The use of solar thermal systems are now widely used, mainly for heating and this is one of the major applications where such systems used. This is where heating, ventilation and air conditioning comes in. In the United States alone, it makes up for 25 percent of energy consumption. The use of solar heating systems will serve as a great help in saving money as well as save in offsetting the use of fossil-fuel-generated energy. In space heating, solar air heat collectors are used which have two types.
The first type is the glazed solar collector and this works primarily for space heating. The air is heated and recirculated all throughout the building through the solar air panel. Such solar heating system works if and only if it is warmer than the building’s or home’s room temperature. It also requires 2 infiltrations in the building for the whole system to work properly.
The unglazed solar collectors on the other hand are for pre-heating of industrial, commercial and institutional make-up ventilation. This is best for buildings that have high-ventilation volume needs. As a result, it turns walls or sections of it into low cost at the same time high-performance transpired solar collectors. In order to do this, a painted and holes metal that serves as a wall exterior. There is a thermal boundary layer of air which is 1mm thick outside the absorber. The conduction happens from the absorber surface and down to the thermal boundary layer. The layer of air is then strained to the perforations which is led to the absorber plate into the ventilation system of the building.
Another solar heating system is called solar roof ponds. It was invented in the 1960’s by Harold Hay. This is a system that includes heating and cooling. It is made of the roof-mounted water bladder that has a movable insulating cover. This system is able to control heat exchange between the inside and the outside surroundings. Controlling can be done through the simple process of covering the bladder during the night and uncovering it during the day. Uncovering the bladder allows it to store heat that can be used during nighttime and the opposite is done to cool the building during the daytime.
Utilizing the sun’s power to heating or cooling advantage is an practical way to save on electricity bills. Aside from the savings, it also makes it easier for people to help the environment since they do not use fossil-fuel-generated electricity. It is like hitting two birds with one stone. This is what solar heating
