The supply temperature refers to the temperature of the fluid (usually air or water) leaving a heating or cooling system to be distributed to the space being conditioned. The return temperature refers to the temperature of the fluid (air or water) after it has circulated through the system and is returning back to the source. The temperature difference between the supply and return temperatures indicates how effectively the system is heating or cooling the space.

How do you calculate sensible heat if you know cfm and temperature difference?
To calculate sensible heat, you can use the formula: Sensible Heat (BTU/hr) = 1.08 x CFM x Temperature Difference (°F). Just multiply the CFM value by 1.08 and then by the temperature difference in Fahrenheit to get the sensible heat in BTU per hour.
What is the purpose of a flow and return on a calorifier?
The flow and return on a calorifier are used to circulate hot water from a heat source into the calorifier and to return cooled water back to the heat source for reheating. This helps maintain a consistent supply of hot water and ensures efficient heating of water within the calorifier.
What is the abbreviation for temperature?
The abbreviation for temperature is "Temp."
In the water analogy of an electric circuit what corresponds to the power supply the resistor and potential difference?
Power supply: Water pump, producing pressure at its output valve.Resistor: A section of pipe. Flow of water loses energy on the way through, due to friction with the pipe's interior wall.Potential difference: Difference in water pressure between the beginning and end of the pipe section.
What detemines the direction of flow of heat between 2 objects in contact?
The direction of heat flow between two objects in contact is determined by the temperature difference between them. Heat will always flow from the object at a higher temperature to the object at a lower temperature until thermal equilibrium is reached.
What should the air temp difference be between the supply and return side of a 4 ton 16 seer unit?
20 degree difference
What should supply air temp be for heat pump heating?
With heat pumps supply air temp will vary with outdoor temp. The colder it gets outside the less efficient the heat pump will be (colder supply air).
How do identify supply and return lines on a th350?
Supply is above and return is under.
What is the difference between supply and return air in an HVAC system?
Supply air refers to the conditioned air that is pushed into a room by the HVAC system, while return air is the air that is pulled back into the system to be heated or cooled again. Supply air is typically cooler or warmer depending on the season, while return air is the air that has already circulated in the room.
Water heater has output of 40000 btuh and a 10 degree water temp differential between the supply and return pipes What is the flow rate in gpm through the coil?
8 GPM

In a(n) fuel oil supply system one pipe is the supply and the other acts as the return.?
In a(n) ____________________ fuel oil supply system, one pipe is the supply and the other acts as the return.
Is it OK to close both the supply vent and return vent in a room?
I would say ok on the supply but not hte return.
How do you find the HCF in c?
For two positive integers: int gcf(int a, int b) { int temp; while (b!=0) { temp=b; b=a%temp; a=temp; } return a; }
How Cold Should the Air Be from your Air Conditioner?
There should be appx 15*-20* difference between return and supply air temps measured at the unit (not the registers).
Difference between change in supply and change in quantity supply?
no
What is difference between individual supply curve and market supply curve?
The difference between individual supply curve and the market supply curve is tat individual supply curve is like a firm. To be able to get the market supply curve you have to have the individual supply curve.
