The need for cooling and heating systems in buildings and automobiles has been influenced by temperature variations created by climate change and weather changes as well as the desire for an appropriate temperature (Mitchell & Braun, 2013). These systems also referred as HVAC, heating, ventilation and air conditioning are made of various component parts. In the process of manufacturing heating and cooling systems, two major issues that are taken into consideration are: Efficiency and Efficacy. Efficiency in relation to consumption of energy i.e. Electric power is crucial in the manufacture of heating and cooling systems. Additionally, users and manufacturers are Continue reading...
