AIRAH Residential evaporative cooling - Water efficiency for evaporative air coolers Best Practice Guidelines

 

Image

This brochure, developed by AIRAH and the Smart Water Fund (SWF), provides information about how consumers can improve the water efficiency of their evaporative air cooling systems. It provides recommendations for purchasing new systems, improving existing systems, and ongoing system maintenance and management. These recommendations are intended for residential and light commercial applications. Information about larger scale commercial, industrial, and agricultural applications is available in a separate guide.

AIRAH HVAC Hygiene Best Practice Guidelines

 

HVAC Hygiene Best Practice GuidelinesThis Guideline establishes the criteria for evaluating the internal cleanliness of HVAC system components and clearly determines when cleaning is required, according to the building use.

The Guideline describes the components of HVAC systems to be evaluated, the types of contamination likely to be encountered and includes for post fire and flood damage assessments. Minimum inspection frequencies for various HVAC systems and components are specified for scheduled maintenance programs.

The Guideline also provides test methods that can be used to verify that a clean system hygiene level has been achieved following a system cleaning or restoration project.

This document also includes recommendations for creating new access openings within HVAC systems where they are required to facilitate the inspection and cleaning of the internal surfaces of system ductwork and components.

This Guideline does not include hygiene inspections or recommendations for either cooking (kitchen hood exhaust) or hazardous (i.e. laboratory, fume cupboard) exhaust systems.

This Guideline does not provide instructions on how to clean or restore HVAC systems but does provide some guidelines on the management of cleaning and restoration projects.

Sustainability Victoria Energy Efficiency Best Practice Guides

 

Sustainability Victoria has developed five energy efficiency best practice guides for business which include:

  • Industrial refrigeration
  • Pumping systems
  • Steam systems, hot water systems and process heating systems
  • Lighting
  • Compressed air systems

These documents are a step-by-step guide to improving equipment energy efficiency and achieving best practice. By following the guides, business will be able to determine what changes can be made in order to reduce operating costs, improve the environment and improve the operation and performance of equipment.

The guides have been developed to lead decision makers and service providers through changes to systems; it is not intended to be a thorough technical guide. References for more detailed technical information are provided in each guide.

The guidelines are located at http://www.resourcesmart.vic.gov.au/for_businesses/energy_efficiency.html
