A solar heating system that utilizes an electic fan to move warm air throughout a home is called a ___ system?
Question:
a)active
b)aggressive
c)convetion
d)passtive
Answer:
There are two general types of systems, active and passive. An active system uses energy to move heat energy around. A passive system uses convection to move the heat (heat can also radiate from warm surfaces to heat people and objects too).
In your question, a fan is used to move heat so it is an active system.
In a room that has sunlight coming into the room through windows warming say the floor, that would be an example of a passive system.
Hi. It has a fan so it's not passive, it must be...?
c
Convection
If it uses a fan then it is an active system. (a)
I guess if the list is all I have to pick from, the answer would be A.
I built and tested one and made up plans for a bigger better one which I will be posting on my website soon. But it is really called a "Forced Air System"
