Introduction

Energy is one of the most fundamental concepts in the 20th century and one of the most important concepts in our daily life. Fossil fuels and other traditional forms of energy have been the major source of energy for a long time. Combustion of fossil fuels produces harmful gases like carbon dioxide that causes greenhouse effect, which results to global warming. Global warming is a serious pollution problem caused by continued use of fossil fuels. Environmental pollution because of these traditional forms of energy is one of the major touching issues in the 21st century . It is also important to note ...

Introduction

As the price of oil and its derivatives fluctuate and reserves of easily accessible sweet crude decline, the cost of energy consumption has increased. Conversely, world energy consumption increased over 49% between 1984 and 2004 [1]. Based on calculations of extraction costs and energy needs, it is clear that fossil fuels are an unsustainable source of energy and as a result, there has been increasing interest in finding alternative methods of energy generation and reducing current use. This interest has been exacerbated due to the negative environmental impact of burning fossil fuels. Buildings are an enormous part of overall energy ...

Abstract

The use of thermistors started when the scientists discovered that metals have a semiconductor property. The inventor of the first operating thermistor is Samuel Ruben. Thermistors are resistors which could vary their resistance with the change of temperature. The industry of thermistor rapidly increases due to its reliability and low price. Then, its uses became wider as more and more devices are installed by the thermistors. As the technology progresses, the use of thermistors in any devices and instruments also developed (Ametherm, np).

What are heat pumps?

Heat Pumps work similarly to the air conditioning units, but unlike the air conditioners they do not have refrigeration units. Heat pumps are simply transferring air from one place to another, For example in summer they are transferring hot air that is inside of building to outside and in winter they transfer hot air to the building.

What makes them an efficient method of air conditioning?
