Call for Members Announced for SPC 40R

From eSociety, November 2018

Standard Project Committee 40R, Methods of Testing for Rating Heat Operated Unitary Air-Conditioning and Heat-Pump Equipment, is looking for members, especially members representing the General and User interest categories.

1.1 This standard provides test methods for determining the heating and cooling output capacities and energy inputs of unitary air-conditioning and heat pump equipment that is heat-operated (see Section 3, “Definitions”).

1.2 These test methods may be used as a basis for rating such equipment, but it is not the purpose of this standard to specify methods of establishing ratings.

2.1 This standard applies to heat-operated unitary air conditioners and heat pumps consisting of one or more assemblies, including engine-driven systems. Where such equipment is provided in more than one assembly, the separate assemblies are designed to be used together.

2.2 Equipment within the scope of this standard may be classified as follows:

a. Component arrangements:
   1. factory-assembled equipment employing heat-operated or mechanical refrigeration cycle or cycles (e.g., a packaged unit)
   2. equipment employing a heat-operated or mechanical refrigeration cycle with indoor and outdoor sections in separate    assemblies (e.g., a split system)
   3. equipment employing a heat-operated or mechanical refrigeration cycle as a liquid chiller with cooling coil in separate assembly    (e.g., chiller)
   4. equipment employing refrigeration cycles and heating functions (e.g., chiller/heater)

b. Method of providing air circulation through indoor section:
   1. with circulating fan incorporated with indoor assembly
   2. without circulating fan, for use with separate fan or air handler, or with heating equipment incorporating a fan

c. Medium for heat transfer to or from the outdoors:
   1. air
   2. water (or brine)
   3. evaporatively cooled condenser (cooling only)

2.3 This standard does not include methods of testing the following types of equipment:
 1. heat-operated absorption and engine-driven liquid chillers not part of a unitary air
   2. electrically driven unitary air conditioners or heat pumps
   3. refrigerating systems employing the Peltier effect
   4. desiccant-based cooling systems
