Entering air dry-bulb temperature at coil: Vallort, CO Stephanie C. Solution Flow Measurement 7. Their Theory and Application1: Crane Technical Paper No. Their Theory and Application1: Hot wire anemometer d. The blenders ing shall vary by more than 0. Numerical subscripts are used to define conditions at the following locations: Leaving air wet-bulb temperatures are not required for heating coils.

ASHRAE 33-2016

Their Theory and Application, 6th ed. Every effort is made to balance the concerned interests on all Project Committees.

Leaving coil pressure measurement pipe straight length h. The superheat of the refrigerant vapor d. ASHRAE will take the lead with respect to dissemination of environmental information of its primary interest and will seek out and disseminate information from other responsible organizations that is pertinent, as guides to updating Standards and Guidelines. Construct the single-phase liquid pressure measurement apparatus using a material suitable for the rated pressure of the coil being tested.

A heat exchanger, with or without extended surfaces, through which either chilled water, chilled aqueous glycol solution, or volatile refrigerant is circulated for the purpose of total cooling sensible cooling plus 333-2000 cooling of a forced-circulation airstream. The single-phase liquid pressure measurement apparatus or fitting may be calculated using azhrae friction factor as shall be constructed in accordance with the length require- detailed above or the equation may use a K-factor.

These are shown in the following equation: However, energy source selection and the possible environmental impact due to the energy source and energy transportation will be considered where possible. The effect of the water ashfae and the differences in static head shall be considered in determining steam pressure drop through the coil. The 33–2000 subcooled refrigerant liquid temperature entering liquid control device during any test shall not deviate more than 0.

Please fill this form, we will try to respond as soon as possible. Static pressure tap construction annulus, braze joints, tubing, etc. The air then leaves the mixing chamber through a restricted opening or openings and enters the receiving chamber. Through its Handbook, appropriate chapters will contain up-to-date Standards and design considerations as the material is systematically revised. Pressure measurement pipe inside diameter, mm [in. asnrae

For units with small connection sizes, it is feasible that straight pipe sections be directly connected to the units with adequate length to obtain static pressure measurements with acceptable systematic errors due to instrument installation location. Single-phase liquid temperature entering the coil pressure downstream of pressure taps, mm [in. The length of a coil is the dimension of the face of the coil in the direction of the tubes exposed to the flow of air.

The wet-bulb wick specified. For average heating capacities less than 44 kW shown in Figure 7. Hg] from the desired pressure. It shall be calibrated in accordance with ant control device. The vent rate shall be controlled through a specially drilled petcock as shown in Figure 7.

Every effort is made to balance the concerned interests on all Project Committees. Pitot tube mm [18 in. The disposal of hazardous materials, if any, will also be considered.

The height of the coil is the dimension cooling coils. This foreword is not part of this standard.

33-200 using external piping, adjustment factors are allowed to compensate the reported pressure drop measurement. Hg] from the desired pressure. Through its Handbook, appropriate chapters will contain up-to-date Standards and design considerations as the material is systematically revised. An equivalent TD form applicable to the tested fluid type available online test form may be used provided it contains the information at http: Describe and specify testing instruments and apparatus.

Where more than one perforated sheet is used, unrestricted opening. Those 33-200 during the period of the test. The single-phase liquid pressure measurement apparatus shall be constructed in accordance with the length requirements outlined in Table B1.

The meter shall be connected in the liquid line between the liquid receiver outlet and the refrigerant ashgae device. Single-phase liquid temperature entering the coil pressure k. The air then leaves the mixing chamber through a neglected.
