The automatic temperature regulator with cooling system is a project to control the ambient temperature of the marine engine automatically to turn on the air cooler. This is also used as a home appliances project. The field of mechanical engineering has a thematic word called "CHANGE" as its backbone.
Humans emit heat, around an average of 100 kcal per hour per person, due to what is known as "metabolism." The mechanism of temperature in the human body maintains a body temperature of about 36.9 degrees C (98.4 degrees F). But the temperature of the skin varies according to the ambient temperature and the relative humidity. To dissipate the heat generated by metabolism in order to maintain body temperature at the normal level, there must be a flow of heat from the skin to the surrounding air. If the ambient temperature is slightly lower than that of the body, there will be constant flow of heat from the skin. But it is the surrounding temperature is very low, as on a cold winter day the body's heat flow rate will be quite fast, so the person feels cold, on the other hand on a hot summer day, the room temperature Is greater than the body, so there can be no heat flow from the skin to the surroundings, so the person feels warm.
