Hi,
We have designed a fresh water cooled condenser for a refrigeration plant at 37 degC inlet water temperature. But later it is found that the inlet fresh water temperature is not stable. In winter it may go below to 5 degC. My question is "will the compressor/condensor unit will function...
Hi,
Iam working on the ventilation design for a Electric switch board room
When the ventilation system is working, the inside condition is to be maintained at 35 deg C.
My client want know that incase of failure of the ventilation system, In how much time the inside temperature will reach 45...
Hi,
We are designing a fan and duct system. The rooms should always be ventilated. As per our client's requirement, if there is a reduction in airflow ( due to any fault), it has to be signalled at remote controlled station. There are two ways to send signal to remote station.
1. By providng...
Dear Walkes Thanks for your response.
But dont't you think that off coil temperature of 43 deg C will make the delta T across the coil to 63 deg C which it seems is a very high delta T for a heating coil. Heating coils are generally not more than 2 rows deep.
Also the temperature difference...
The design room temperature inside the room is 5 DegC. Outside temeprature is sub zero deg C( around -20DegC). The room should be heatde suitably. In general what is the good engineering practice between supply air air temperature and the room temperature ( Delta T)for heating applications. Is...
It seems my question was not very clear. My question is not related to Carrier HAP program but is related to the more fundamental concept in relation E20 Carrier manual calculation form. I try to be more clear with following illustration.
System : Chilled water with 44/54 deg delta T...
Can someone explain the following in refrence to Carrier E-20 method of Cooling load Calculations
1. What is the diffrence in "Indicated ADP" and "Selected ADP".
2. What are the criterion for selecting the "Selected ADP"
3. What is the effect of Selected ADP on...
