Introduction

As known to most individuals, for thousands of years man has always found the need to manipulate resources towards the production of energy as a means of survival. Dating back to prehistoric times when fire had been created, spanning to what we see presently with nuclear fusion reactors and hydroelectric power plants, all which are a staple production sources for reliable energy. Although, through changing times, the mindset and perception of many consumers has become more cognizant of the negative impacts that come with the production of reliable sources of energy. In an effort to preserve this planet we call earth, more stringent attempts are being implemented in the ways we consume and produce energy in hopes of preserving our precious ecosystem.

In order to preserve our ecosystem and yet still meet the worlds present day energy demands, we must look at the negative impacts which inevitably come with the production of reliable energy. As with many means of energy production, one byproduct in particular that has raised concern worldwide, and this is emission byproducts associated with the combustion of natural gases and petroleum products. Many of these byproducts are discharged directly into the atmosphere and have a detrimental effect on the ecology of the surrounding area.

Along with the hazards that emissions pose to the environment, there is also an underlying consequence presented through the production of reliable energy, cost. The amount of money the United States invests into the extraction of energy producing resource and energy production comes between $290-610 billion dollars. Not only does this have any effect on government around in the United States, it also poses an issue to...

Disadvantages

When discussing the disadvantages of using an air-source heat pump system, we must observe that there are inevitable limitations present for the operation of the system. One constricting factor that hinders the mass usage of these systems, is that the systems thermal efficiency is dependent on the heat reservoirs temperature ergo the temperature of the outdoor air. Considering the working fluid that is used to cycle through the air-source heat pump has properties allowing for phase changes to occur with little added energy and low boiling points, how does the process react to geographic areas with frequent sub-zero temperatures. Here in hand lays a key limiting factor. Air-source heat pumps operate most efficiently when they are install in areas with mild climate where drastic temperature fluctuations occur less often in these areas.
