How to make an air-conditioner for really hotdays!
Appears trivial. However, good bit (Crazy of course) of chemical engineering here:
If there is no air flow the thermocole box will slow down the ice melting. If the fan runs there is no escape from the mCp(delT) (airside) from melting an equivalent quantity of ice. Slowing the fan will slow it at the cost of reduced cooling.Koushal Patelany way to slow down the melting of ice?
The basic problem is that if any heat is added to ice it will melt consistent with its latent heat. In this case the fan is blowing outside warm air into the chamber. The higher temperature of the air melts the ice.Koushal Patel@A.V.Ramani - Sir I was asking about any material which can be mixed with ice to slow down its melting. Is it possible?
Unfortunately, any addition to the water will depress the melting point leading to faster melting.
This article will help to understand this:
I have heard of salt OR pepper being added to salt to make it melt slower.Koushal Patel@A.V.Ramani - Sir I was asking about any material which can be mixed with ice to slow down its melting. Is it possible?
Not sure if it's true. Here's a link:
Not really. What is said in the reference is the same mentioned in my post. Adding salt lowers the melting point, does not affect the amount melted.Ankita Katdareto make it melt slower.
AS AKNITHA SAID IS CORRECT ADDING SALT TO ICE IT LOWER THE MELTING POINT I HAD DONE IT practically 😀
The total cooling capacity is still invariant. The latent heat does not change.sudharsansrinivasAS AKNITHA SAID IS CORRECT ADDING SALT TO ICE IT LOWER THE MELTING POINT I HAD DONE IT practically 😀
