Test methods of energy-saving for air-conditioners and similar equipment with infrared human sensor
This document describes a method in laboratory to assess the performance of ultraviolet germicidal irradiation (UVGI) devices which will be mounted in-duct in heating, ventilating and air-conditioning (HVAC) systems. The method includes the detailed requirements for test rig, microorganisms, procedures, data calculation and result report to determine the UV dose to model microorganisms by an UVGI device at several airflow rates. By the testing results, the capacity of in-duct UVGI devices for air disinfection can be evaluated and compared reliably. If the susceptibility constant of a given microorganism is known, the inactivation rate of that micro- organism by the tested UVGI devices can be further calculated.

What is BS EN 17192 about? BS EN 17192 discusses ventilation for buildings. Ventilation not only affects physical health, it also impacts the mental health of the occupant. Sometimes effects of exposure to CO are subtle, and occupants do not realize what may be causing their symptoms. Due to this, it is important to test ventilation for buildings. BS EN 17192 specifies methods to test rigid or semi-rigid non-metallic ductwork under laboratory conditions. On-site tests are excluded. Note: BS EN 17192 does not include flexible ducts such as those made of textiles, non-metallic spiral ductwork, or others, which are handled in EN 13180 or ductwork made from insulation duct board, which is handled in EN 13403 . Requirements for the airtightness of the ventilation system for non-residential buildings are given in EN 167983 . For residential buildings, it is essential to apply national rules. Who is BS EN 17192 for? BS EN 17192 on ventilation for buildings (non-metallic ductwork) is useful for:
Ventilation for buildings. Ductwork. Non-metallic ductwork. Requirements and test methods
1.1 This test method measures air-leakage rates through a building envelope under controlled pressurization and depressurization. 1.2 This test method is applicable to small temperature differentials and low-wind pressure differential, therefore strong winds and large indoor-outdoor temperature differentials shall be avoided. 1.3 This test method is intended to quantify the air tightness of a building envelope. This test method does not measure air change rate or air leakage rate under normal weather conditions and building operation. NOTE 1—See Test Method E741 to directly measure air-change rates using the tracer gas dilution method. 1.4 This test method is intended to be used for measuring the air tightness of building envelopes of single-zone buildings. For the purpose of this test method, many multi-zone buildings can be treated as single-zone buildings by opening interior doors or by inducing equal pressures in adjacent zones. 1.5 Only metric SI units of measurement are used in this standard. If a value for measurement is followed by a value in other units in parentheses, the second value may be approximate. The first stated value is the requirement. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements see Section 7. 1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

What is ISO 21083-1 about? ISO 21083 discusses the efficiency of air filtration media against spherical nanomaterials. ISO 21083-1 is the first part of the ISO 21083 multi-series. ISO 21083-1 specifies the testing instruments and procedure for determining the fractional filtration efficiencies of flat sheet filter medium against airborne nanoparticles in the range of 20 nm to 500 nm. Nanoparticles, referring to particles with at least one dimension below 100 nm, generally have higher mobility than larger particles. Because of their higher mobility and larger specific surface area, available for surface chemical reactions, they can pose a more serious health risk than larger particles. Thus, particulate air pollution with large concentrations of nanoparticles can result in an increasingly adverse effect on human health and an increased mortality Who is ISO 21083-1 for ? ISO 21083-1 on measuring the efficiency of air filtration media against spherical nanomaterials is useful for: Air filter manufacturers Pollution control bodies Health and safety bodies Quality control personnel Why should you use ISO 21083-1
