How To Measure Velocity And Flow

In HVAC/R applications it is helpful to understand the methods used to determine air velocity. Air velocity (distance traveled per unit of time) is most often expressed in feet per minute (FPM).  Multiplying air velocity by the area of a duct allows you to determine the air volume flowing past a point in the duct per unit of time. Volume flow is generally measured in cubic feet per minute (CFM).

How do I pressurize an anteroom?

There are several techniques for managing safe and reliable pressurized rooms in healthcare and laboratory applications. When anterooms are present, such as those used for isolation rooms and pharmacies, it is not always clear how the anteroom should be pressurized in relation to the adjoining room and hallway.

Guide for Establishing Relative Humidity Levels in Operating Rooms

Successful surgery depends not only on the performance of medical professionals, but also on the integrity of the environment. Relative humidity is a critical component in maintaining the safety and performance of an operating room (OR).

Can A Room Pressure Monitor Help Me Save Energy?

Monitoring and controlling room pressure in laboratory and healthcare settings can do more than just ensure directional airflow (positive or negative pressure rooms). Proper room pressure also contributes to saving energy. Overpressure or under-pressure scenarios mean that airflow, or even temperature control, are not optimal.

What is a Vivarium?

A vivarium refers to an enclosed area designed to provide a stable environment for animals and plants for observation or scientific research. Often, vivariums contain a portion of an ecosystem for a particular species with controlled environmental conditions on a smaller scale. A vivarium contains racks of various sizes dependent on the species it contains.

Energy Savings Strategies For Operating Rooms

Operating Rooms consume a great deal of energy, considering the high airflow requirements needed, bright lighting, and significant plug load from patient care equipment. There are, however, strategies to conserve energy and still meet the stringent safety requirements of maintaining positive room pressure. Two conditions need to be met to enable OR energy savings. The first is a method to trigger occupied and unoccupied states. And the second is to act on that state change to setback both temperature and airflow.

Where are hospitals consuming the most energy?

Hospitals are one of the most energy intense buildings on the planet.

As budgets are becoming tighter, many hospitals today are moving towards energy management for cost savings. In breaking down how hospitals can save on energy costs, the first step is to understand what areas of the hospital consume the most energy. Keep in mind that energy consumption varies for each individual hospital based on certain factors such as the hospitals primary function and geographic location.

What Is The Difference Between An Anteroom And An Ante Area?

Engineering proper HVAC systems for critical environments often involves distinct areas of room pressure control and directional airflow. An anteroom between a primary room and corridor ensures a safe airflow buffer zone between the controlled pressurized space and an unclean area. The two spaces are separated by a completely walled area with a door. However, in some applications an ante area without walls or a door can achieve the safe effect.

How to Prevent Mold Growth

Although mold has many medical uses, it can be a huge problem for homes and buildings, especially if mold growth goes undetected. Mold spores spread easily and can grow anywhere, including carpet, clothing, food, paper as well as drywall, areas inside walls, around leaking or condensing pipes, and above ceiling tiles. Since mold cannot be completely eradicated and can be costly to fix, the best approach is to prevent mold before it becomes a problem. So how do you prevent mold growth?

What Are Protective Environment Rooms?

Protective Environment (PE) rooms are hospital rooms designed to protect a high-risk immunocompromised patient from human and environmental airborne pathogens. These are positive pressure rooms intended to keep patients safe during recovery from cancer treatment or stem-cell transplant.
