How to combine heating and air conditioning- An overview of geothermal heating and cooling -Heating and cooling in the global warming framework Heating and air conditioning systems are nowadays an important tool to consider especially because the constant global warming results in the gradual appearance of only two seasons: extremely hot summers and freezing winters. Heating and cooling systems have become the answer to the question whether it is still possible to lead a comfy life and enjoy the right temperatures at home, at work, at school or while chatting with our friends in downtown. Those who are neither familiar with the matter nor with the functions of such systems should read this article and seize the benefits of this long-term investment. Quest for alternative solutions After so many attempts at creating the adequate premises for a postmodern lifestyle, which only damaged the environment and destroyed the ecosystem, it is time for a change. An essential step in this transformation process is decreasing the impact of our actions on the environment by using alternative sources of energy. It needs to be mentioned that there are two types of heating and air conditioning systems: conventional and geothermal ones. Of these two categories, only one implies the combination of heating and air conditioning and this is best known as the geothermal heating and cooling.The final beneficiaries of these revolutionary money and energy savers are both the homeowners and the builders themselves. As for the latter, they have immediately seized this unprecedented opportunity to substantially increase their sales by offering their customers a unique, 2 in 1 product: a heat-pump in winter and an air conditioning system in summer. Advantages The advantages of this practice are obvious. Firstly, it provides the users with the right temperature, by preventing them from melting down in summer and freezing in winter. What such a system does is to use the earth as a main heat source. Therefore, conditioned air and heat are distributed evenly throughout the house or building, according to the users’ needs and desires. To put it in a nutshell, the warmth located in the earth is best used to heat the building in winter and cool it in summer. Secondly, its efficiency is justified by the low costs, when it comes to energy bills. Apparently, geothermal heating and air conditioning systems are more expensive at their purchase than conventional systems. However, the energy saved by the users is a guarantee of the savings made on utility bills (for instance on hydro, heating and air conditioning costs altogether). Nevertheless, it is important to mention that these systems also ensure the protection of the environment, because the pollution that they cause is significantly inferior to that caused by heating and air conditioning systems based on fossil fuel. The explanation is that, while conventional systems use combustion to produce heat, geothermal ones creates heat by moving it from one place to another one. Furthermore, such systems can be deemed a renewable energy form. Fourthly, their maintenance is simple, based on two procedures: either cleaning the pipes by means of acid wash or replacing the well pumps after a long period of time, usually exceeding 10 years. Perspective on lowering global warming effects Considering that human activities have a major contribution to the global warming process and that greenhouse effect is a result of the burned fossil fuel, agriculture and land clearing, this geothermal method of heating and cooling is highly recommended today. On balance, it is obvious that such a method is not only an efficient means to diminish the negative effects of our actions on the environment, but also to save energy and money on utility bills. |
