Chemical Product Applications in HVAC Systems
It is generally agreed that source removal of contaminants remains the single best method for cleaning and decontaminating HVAC systems. However, chemicals may be applied within HVAC systems for a variety of reasons. This paper provides an overview of chemical products and associated techniques utilized in and around HVAC systems.
Ultraviolet Lighting Applications in HVAC Systems
It is generally agreed that source removal of contaminants remains the single best method for cleaning and decontaminating HVAC systems. One of the tools used to improve air quality from HVAC systems is the use of ultraviolet lighting within the system, intended to decrease the level of airborne pathogens and allergens going through the HVAC system and thus into the indoor air environment. Currently a broad range of information exists regarding the use and efficacy of ultraviolet lighting. This paper provides direction in the use of ultraviolet lighting applications in HVAC systems.
Ozone Applications in HVAC Systems
Source removal of contaminants remains the single best method for cleaning and decontaminating HVAC systems. However, HVAC systems sometimes require treatment for odors or the reduction of microbial contamination. One remedy that has been used for these problems is ozone, a form of oxygen. Currently a broad range of information exists regarding the use and efficacy of ozone. This paper provides direction in the use of ozone applications in HVAC systems.
Interior Insulation Applications in HVAC Systems
One of the critical aspects of HVAC systems is the insulation used inside metal ductwork, air handlers, mixing boxes, and other components of HVAC systems. Insulation materials need to be understood and handled properly to ensure optimum system performance and compliance with regulations. This paper covers the specific topic of internally insulated sheet metal ductwork and HVAC system components.
Inspection & Cleaning of Open Air Plenums in HVAC Systems
Open air plenums can be found in all types of buildings as well as aviation, marine and transportation applications. The plenums within these buildings can often be contaminated with particulate ranging from simple nuisance dust to other hazards. Soiled open air plenums can adversely impact the conditioned space and this paper provides guidance for the inspection and cleaning of these areas.
