Solar HVAC For Energy & Environment

As more and more homes throughout US are opting for energy efficient green designs, HVAC which stands for Heating Ventilation And Cooling systems are getting a lot of attention. Improvements in HVAC are considered key in helping reduce greenhouse gas emissions as efficient heating and cooling will lower energy expenditure, which in turn will mean lower carbon emissions. So while a properly maintained HVAC system has the potential to bring down your power consumption considerably, a solar HVAC system can reduce it still further or even remove the utility bill from the equation altogether.


Why solar heating and cooling matters


It is estimated that 75% of all residential energy consumption in the US is related to water heating, space heating and cooling. 115 million homes throughout the US consume energy to the tune of $266 billion every year to keep their homes warm during cold months and vice-versa. Likewise, in the commercial sector $50.76 billion is spent on regulating the environment of 4.8 million buildings.

These are obviously great costs which in the presence of available solar technologies seem entirely redundant.


How does Solar HVAC work? 


There are many different ways to generate and regulate heat in a building. Solar heating and cooling systems work by harnessing either the sun’s thermal energy, or its light to power HVAC systems. Also called Solar Heating and Cooling (SHC), these technologies are some of the most efficient ways to keep your home warm and/or cool.


Solar heating and cooling systems can be used for a variety of different applications…


Solar air heating


A solar collector with a matrix of copper pipes is used in a solar heater. Thermal energy from the sun heats the air in the copper pipes, which then flows back into the building via a fan. These systems are very efficient too, converting 70%-90% of sun’s heat into usable energy. They typically employ either water, or antifreeze to collect the thermal energy, and then a heat exchanger to transfer it into the air.


Solar water heating


These work on the same principle as a solar air heater does. SEIA estimates that as many as 9 million solar water heaters are placed in the US every year. Solar water heaters are available in two formats – active and passive. Active solar water heaters utilize an electric pump to circulate the water within the collector, while passive heaters use thermodynamics and gravity to do the same.


Solar cooling


Solar energy can also be used to cool a building, just like it can be used to keep it warm. The American Council for an Energy Efficient Economy estimates that as much as $15 billion is spent every year to keep homes cool. Two types of solar ACs are available – Hybrid solar ACs which use photovoltaic panels to generate electricity for powering a regular AC, and evaporative coolers which work by evaporating and cooling water.


Solar HVAC is the natural evolution of regular heating and cooling systems and presents numerous advantages over traditional systems. While they could cost more upfront, the resulting savings can pay back the price over the life of the system. Solar heating and cooling systems are efficient, low on maintenance, and do not use any toxic chemicals that are hard to dispose of.
