Method of Test for Direct-Expansion Ground Source Heat Pumps

1. PURPOSE:
The purpose of this standard is to provide a method of test to determine capacity and efficiency of direct-expansion ground source heat pumps.

2. SCOPE:

This standard applies to factory-assembled unitary heat pumps (that utilize indoor air as energy sink on heating and the energy source on cooling and a refrigerant as the heat transfer medium in the ground) and are used for direct-expansion (DX) ground source systems.

SPC 198P Proposed Standard authorized (Tech Weekend) Oct. 24, 2008.
Method of Test for Rating DX-Dedicated Outdoor Air Systems for Moisture Removal Capacity and Moisture Removal Efficiency

1. PURPOSE:
The purpose is to prescribe test methods for determining the moisture removal performance and efficiency for DX Dedicated Outdoor Air Systems (DX-DOAS).

2. SCOPE:
This method of test applies to air-cooled, water-cooled or water-source factory-assemble DX-DOAS produce which includes reheat to condition 100% outdoor air to provide dry air at a dry-bulb temperature at or near the design room temperature, directly or indirectly to the conditioned space. The product may pre-condition outdoor air by containing an enthalpy wheel, sensible wheel, desiccant wheel, plate heat exchanger, heat pipes or other heat or mass transfer apparatus.

SPC 199P Proposed Standard authorized (New York) January 23, 2009.
A Method of Test for Rating the Performance of Industrial Pulse Cleaned Dust Collectors.

1. PURPOSE: The purpose is to provide a quantitative laboratory test method for determining the performance of Industrial Pulse Cleaned Dust Collectors using a test dust.

2. SCOPE: This method of test applies to bag, cartridge, or envelope industrial dust collectors that recondition the filter media by using a pulse of compressed air to discharge the dust cake from the filter media while the air cleaning device remains on line.

SPC 200P Proposed Standard authorized (Louisville) June 25, 2009.
