Is 102.56 degree celsius a high temperature?
In terms of hot to touch, yes, very high.In terms of the heat it takes to melt a metal, no, it is not very high
What does a low U-value mean?
It can also be referred to as an 'overall heat transfer co-efficient' and measures how well parts of a building transfer heat. This means that the higher the U value the worse the thermal performance of the building envelope. A low U value usually indicates high levels of insulation.
What are u-values?
A U value is a measure of heat loss in a building element such as a wall, floor or roof. It can also be referred to as an 'overall heat transfer co-efficient' and measures how well parts of a building transfer heat. This means that the higher the U value the worse the thermal performance of the building envelope. A low U value usually indicates high levels of insulation. They are useful as it is a way of predicting the composite behaviour of an entire building element rather than relying on the properties of individual materials. By Andreea Teodora Merlan
What do plus and minus temperature signify?
Its signifies that the temperature maybe high or low ..
What is the difference between triangular and square pitch in evaporators?
Square pitch is used in HEX and condensers when a fluid that is prone to fouling is flowing through the shell side. Square pitch allows for easier cleaning but the heat transfer isn't as high as triangular pitch because less tubes can be placed. If you don't have a fluid that is prone to fouling (adding layers of junk to the tubes) you can use triangular which allows you to place more tubes in the HEX so higher heat transfer.
