is there such thing as condenser/evaporator capacity of an aircon?
how to compute for that?
thanks!

You solder a coupling with a pressure port onto the tube.plucker_08 said:do i have to bore the tube or just place the transducer around the pipe.?
momentum_waves said:Plucker_08, if this is an industrial application, then I'd suggest that you employ the services of a professional consultant.
If this a student project, then you will have a lot of reading to do.
These are simple facts of life. Some consultants have spent years researching & applying the principles in practice. This comes at a price, unfortunately - time <=> money.

velz said:i want to calculate the mass flow rate of hot water in the heat exchanger?
my known datas are...
In the first heat exchanger exhaust gas flows with 650 c temperature inlet and mass flow rate is 18.7 m3/min
In the second heat exchanger hot water flows with 27 c temperature inlet and 90 c temperature outlet......
here i want to calculate mass flow rate of hot water in the second heat exchanger?
and how to calculate cp value for both exhaust gas and water?
russ_watters said:There is a theoretical maximum capacity of any heat exchanger, based on the delta-T and flow rates of the fluids on each side of it.
The heat exchange capacity of an air conditioner is typically calculated by multiplying the airflow rate (measured in cubic feet per minute, or CFM) by the temperature difference between the incoming and outgoing air (measured in degrees Fahrenheit). This value is then divided by 12,000 to convert it to tons of refrigeration, which is the standard unit of measurement for air conditioning capacity.
The heat exchange capacity of an air conditioner can be affected by a variety of factors, including the size and efficiency of the unit, the ambient temperature and humidity, the insulation and ventilation of the space being cooled, and the presence of any heat-generating equipment or appliances in the space.
Yes, there are multiple methods for calculating heat exchange capacity, including the "rule of thumb" method, which uses a rough estimate based on the square footage of the space being cooled, and the more precise "load calculation" method, which takes into account specific details about the space and its cooling needs.
The heat exchange capacity is a crucial factor in determining the performance of an air conditioner. A unit with a lower capacity may struggle to effectively cool a space, resulting in longer run times and higher energy consumption. A unit with a higher capacity may cool a space too quickly, leading to frequent on/off cycles and potential temperature fluctuations.
In some cases, the heat exchange capacity of an existing air conditioning system can be increased by upgrading to a larger or more efficient unit, improving insulation or ventilation in the space, or adding supplemental cooling equipment. However, it is important to consult a professional to determine the best course of action for your specific situation.
