Heating and cooling is a process. A paradox of sorts since it is both a simple and a complex process. It is interesting just how much this one process influences our lives, making them either more comfortable or less comfortable. Temperatures have been proven to have an effect on our mental stability as well as our attitudes. This makes heating and cooling a very vital process in our day to day lives.
Heating and cooling processes are all basically the same; the main similarity being the end result. In addition to this, heating and cooling systems all have sources of warm or cold air e.g. a furnace, a means of equally distributing this air to the destination and a gadget that is used to regulate and control the system e.g. a thermostat. All these systems also use one principle in all their processes. This principle is that heat always moves from a warm place to a cooler place. Almost like saying, opposites attract. No matter the system in use, the principle used is always that one. Furnaces and heaters will therefore emit hot air which is then emitted to the cold areas while air conditioners let out cold air into hot areas. Another common thing about heating and cooling processes is that they all use up energy/fuel. This file may either be in the form of electricity, gas or even petroleum.
Like mentioned earlier, the process is simple yet complex. A simple principle carried out in a complex manner. The next time you get yourself a heating and cooling system, you will be in the know about how it works.
