ANSI/ASHRAE 62.1 Addendum h-2012 可接受室内空气质量的通风

62.1-2010, Table 6-1, includes ventilation rates for ôSports arena (play area)ö and ôGym, stadium (play area).ö Both space types have ventilation rates based on floor area only, the per person rate is zero. Users of the standard have expressed interest in applying demand controlled ventilation to these space types, which is effectively prohibited by the lack of a per person component to the ventilation rate. This proposed addendum replaces both of these space types with ôGym, Sports Arena (play area)ö, with Rp = 20 cfm/person and Ra = 0.06 cfm/ft° and assigns this new space type with an air class of 2 rather than class 1 from the first publication public review version.

Ventilation for Acceptable Indoor Air Quality

ANSI/ASHRAE 62.2o-2012 低层住宅建筑物的通风和达标的室内空气质量

This proposed change clarifies that a system must be operated in order to achieve the stated purpose of the standard to define minimum requirements for acceptable indoor air quality. Currently the standard is vague such that a system could be installed and turned off and be in compliance. A non-operating system cannot achieve the air change rate required in Section 4.1 of the standard. Elsewhere in the standard (Section 4.4) it is stated that: 'Readily accessible override control must be provided to the occupant.' This proposed change makes it clear that the override control is modifying or suspending normal operation.

ANSI/ASHRAE 62.2 Addendum q-2012 低层住宅建筑物的通风和达标的室内空气质量

Historically, local exhaust fans have been permitted to serve the dual function of providing whole-house ventilation and local exhaust. When serving as dual-duty fans, the whole-house rate and the local exhaust rate have not been required to be additive. This proposed change is needed to clarify that the whole building ventilation rate can be credited towards the local exhaust rate, and that the rates are not required to be additive.

Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings

ANSI/ASHRAE 62.2 Addendum m-2012 低层住宅建筑物的通风和达标的室内空气质量

This proposed addendum deletes Section 4.1.2 Alternative Ventilation which allows for 'other methods' to be used to provide the required ventilation rates but provides no guidance. The proposed addendum adds a new Section 4.6 Equivalent Ventilation which along with a new definition for annual exposure provides a basis for alternative ventilation system designs by requiring that they provide the same or lower annual exposure as would be provided by complying with Section 4.1.

Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings

ANSI/ASHRAE 62.2 Addendum f-2012 低层住宅建筑物的通风和达标的室内空气质量

This is the second public review of proposed Addendum f with changes based on a comment from the first public review. These proposed changes were made to extend the application range of Table 5.3 and to include some updated values based on newer data.

Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings

ANSI/ASHRAE 62.2 Addendum n-2012 低层住宅建筑物的通风和达标的室内空气质量

This proposed addendum to 62.2 incorporates a revised method of calculating infiltration airflow using normalized leakage, with a revised height adjustment exponent, and a new Appendix that includes weather and shielding factor (wsf) values. This infiltration air flow rate would then be used to determine the required mechanical ventilation fan flow rate requirement for meeting the standard.

Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings

ANSI/ASHRAE 62.2 Addendum k-2012 低层住宅建筑物的通风和达标的室内空气质量

This proposed addendum clarifies the difference between intermittent whole-house ventilation and intermittently operating local exhaust ventilation by adding a definition for intermittent ventilation and revising the language in Sections 5 and 7 to refer to demand controlled local exhaust.

ANSI/ASHRAE 62.1l-2012 可接受的室内空气质量通风

This proposed addendum adds a refrigerated warehouse space type to Table 6-1, providing revised ventilation rates for these spaces. These rates include a 'People Outdoor Air Rate, Rp' which will require ventilation during periods of expected occupancy, but do not include an 'Area Outdoor Air Rate, Ra' which will allow the ventilation rate to be zero for refrigerated warehouses with no occupants. Note E to Table 6-1 is modified to indicate that if combustion powered equipment (e.g., a propane forklift) is used in the space, additional ventilation is required.

ANSI/ASHRAE 62.2 Addendum h-2011 低层住宅建筑物的通风和达标的室内空气质量

This proposed change to Appendix A provides clarifications, with one exception (the Section A2 addition). All the other changes (except the A2addition) are minor, clarifying rather than altering the intended meaning. Currently Appendix A does not indicate whether to apply the infiltration credit, Section 4.1.3, before or after Section A3. In some cases, the order in which Sections A3 and 4.1.3 are applied will affect the final whole-building ventilation rate (in cases where Section 4.1.3 zeros out the whole-building ventilation rate). It seems logical to use the order stated in the proposed change to Section A2.

Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings

ANSI/ASHRAE 62.2 Addendum e-2011 低层住宅建筑物的通风和达标的室内空气质量

This proposed addendum would require HVAC systems covered by Section 6.7 to be designed to accommodate the pressure drop imposed on them by the installed filters to ensure that sufficient airflow is not inhibited. This proposed change includes a requirement to provide the needed information on design airflow and maximum allowable clean filter pressure drop so that the filter can be replaced properly. Since the needed information on clean filter pressure drop is not routinely available at present, the proposed change would not take effect until January 1, 2014.

Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings

ASTM D5032-11 用甘油水溶液法保持恒定相对湿度的标准操作规程

Controlled relative humidity environments are important for conditioning materials for shelf-life studies or for investigating the change in physical or dielectric properties after exposure. The use of aqueous-glycerin solutions reduces the possibility of contamination of the materials or corrosion of electrode systems which would be more likely to result from saturated salt or acid water solutions. Applicable material specifications should state the exposure conditions, including time, temperature and relative humidity that a material should be subjected to before subsequent testing. Typical conditions are given in Practice D618 or D6054.1.1 This practice describes a method for obtaining constant relative humidity ranging from 30 to 98 % at temperatures ranging from 0 to 70°C in relatively small containers by means of an aqueous glycerin solution. 1.2 This practice is applicable for closed systems such as environmental conditioning containers. 1.3 This practice is not recommended for the generation of continuous (flowing) streams of constant humidity unless precautionary criteria are followed to ensure source stability. 1.4 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 and health practices and determine the applicability of regulatory limitations prior to use.
