Does anyone have table of expected TD for evaporator and condenser for different type of equipment and different ambient conditions?
Like air to water chiller, water to water chiller, refrigeration plant for freezing of goods and etc......

I think these figures are in Heatcraft manual. You can download that. Somewhere in this forum that site is also given

Hi smpsmp45!
Did you mean Heatcraft engineering manual?

Actually I am away from the office. I can get the exact site once I am back in the office.

Nut I think Mr. Samarjit sen thread on this has all the information

Hi there,

Here are some figures :

Tai ----- air entering temperature
Tao -----air outlet temperature
Te ------Evaporating temperature
Twi ------water entering temperature
Two-------water outlet temperature
Tc---------condensing temperature



Air conditioning (evaporator) :
Tai-Tao = 8 to 10 °C
Tai-Te=16 to 20°C
Tao-Te=8 to 10°C

Refrigeration (evaporator) :
Tai-Tao = 3 to 5 °C
Tai-Te=5 to 10°C (evaporator TD) take low TD for high relative humidity
Tao-Te=3 to 5°C

Water Chiller (evaporator) :
Twi-Two=5°C
Twi-Te=10°C (evaporator TD)
Two-Te=5°C

Air cooled condenser :
Tao-Tai=5 to 10°C
Tc-Tao=5 to 10°C
Tc-Tai=10 to 20°C (condenser TD) take low TD in design for hot climate so the condenser will be bigger.

Water cooled condenser :
Two-Twi=5°C
Tc-Two=10°C
Tc-Twi=15°C (condeser TD)

Hope this helps.
Cheers

Thank you Lana for the table. It will be of great help.

Nike123, the Heatcraft Engineering Manual states the Td for evaporators. I shall try and locate some details which you have asked for, but it may take some time. Lana has provided your requirement.

Thanks Lana!
That is what I asked, and I think that would be of great value to me and others.

Thanks Samarjit Sen. There is no rush, take all the time you need. I am not going anywhere.:D

Dear Lana,
Do you have the TD table for Air Source Heat Pump?
