Condenser Water Pipe Sizing Chart

Condenser water piping sizing me27272727 mechanical 19 oct 15 15 31 we typically size the velocities for 5 8 fps and pressure drops of around 2 ft 100 ft staying below 4ft 100 ft in most applications.

Condenser water pipe sizing chart. The pipe size may be selected on the basis of. Secondary pumps load flow x deltat load equation 4. For r 404a and r 22 medium temperature 2 psi is used. For the tower piping circuit the pump must overcome the piping flow friction loss.

The next standard size larger than 22. It must also provide the energy head necessary to raise water from a low to a higher static head level. This too indirectly impacts the sizing and selection of some fluid handling equipment. Of course the same pipe sizing requirements of ashrare 90 1 discussed above are also included in ashrae 189 1.

These line sizing charts are based on a suction pressure drop equivalent to a 2 f change in saturation pressure and liquid line pressure drop of 5 psi. Velocity usually pipes less than 50 m in length. Refrigerant pipe sizing chart. Different refrigerants will have different pressure changes based on elevation.

Iapmo 2015 2015 upc water pipe sizing calculator iapmo. Selecting the appropriate pipe size nominal bore for a particular application is based on accurately identifying pressure and flowrate. The condenser to the evaporator the refrigerant pressure is lowered. Piping systems dimensions of pipes and tubes materials and capacities pressure drop calculations and charts insulation and heat loss diagrams.

Calculating cooling loads calculating chiller and cooling tower refrigeration in tons. If a condensate unit is chosen to collect the water then the anticipated condensate must be determined and the collection device sized accordingly. Chilled water piping system types typical configuration load valves installed cost pumping cost constant primary flow 3 way lowest highest 3 primary secondary 2 way highest medium variable primary flow 2 way medium lowest. Hvac chilled water system pipe sizing excel calculator for free chilled water air conditioning systems are commonly used in applications that need large cooling capacity such as hypermarket indus.

To size refrigerant piping. Chilled water systems chilled water system equations evaporator and condenser flow rates. For r 404a low temperature 1 psi. Using this guide this guide covers r 22 r 407c r 410a and r 134a used in commercial air conditioning.
