Specific Examples

hvac_hepa-jpg.ashx• You might require a filtration system that can meet certain performance standards such as ASHRAE 52.2. This particular standard defines the minimum efficiency reporting value (MERV) to describe filter performance rating).2097_28th_sig Although this new standard is applicable to the testing of any type of air cleaner, it has been primarily tailored to high-efficiency dry filters used in hospitals, laboratories, and clean rooms.

• Your needs might dictate an operator exposure assessment at a specific operation. We will identify your hazards of the operation, potential exposure, and then provide exposure control options. Here we are applying a principle of ventilation: Conservation of Mass and Energy. These methods are based on the same basic laws in the prominent use of physical sciences.  We need to determine how much air is required, which dictates the horsepower for the fan to convey the design airflow. Industrial Ventilation: A Manual for Recommended Practice for Design, a manual for recommended practices for the design of industrial ventilation systems, written by ACGIH®, provides us with recommendations on how to assess the exposure and provide a proper design based on these principals of ventilation.  This includes hood design, fans, air cleaning devices, and design calculations for proper conveyance and energy considerations. We are currently using the 28th edition manual.

• You might require a solution for a humidity problem. We can provide, a moisture load calculation for specific humidity controlled environments such as seed storage, food processing, pharmaceutical and nuetracuticals processes, healthcare facilities, electronics and semiconductors, and DOE and DOD facilities. We can provide an on-site assessment of your specific operation. Moisture loads come from several different sources, so typically we look at both internal and external sources. Moisture may be generated from the process itself, people, wet surfaces, open gas flame or it can infiltrate through door openings, permeation, cracks, wall openings, and exterior walls. Fresh air or make-up air if required is always a major contributor.

 

 

• Your needs might require a DOAS or a new make-up air system. Make-up air either replaces the exhausted air in a building or it provides positive pressure to a space depending on its duty requirement. Understanding the sensible and latent cooling loads would be necessary in order to meet required temperature and humidity set points to control environments. These are critical in applications such as seed storage, food processing, and pharmaceutical manufacturing. Hospital and healthcare facilities, electronics, and semiconductor manufacturing sites and DOE and DOD facilities are also suspect to these needs. We can provide an on-site assessment of your specific operation to tailor the solution to fit your needs.
