Filters on Fan Powered Terminal Units

September 8, 2020

By: Gus Faris & Matthew Crump, PE


Adding a filter that has greater efficiency than just a throwaway fiberglass filter can be done but could require modifications to the unit.  Each individual unit’s size, design, and operating environment would have to be considered to determine the right route to take to ensure the performance of the unit is not compromised by the addition of the filter. Also, this analysis was done considering the initial pressure drop across the filter.  As the filter is used and becomes...

Energy Efficiency: Water Source Heat Pumps

August 21, 2020

By: Matthew Crump, PE

One of the most important factors in selecting any piece of HVAC equipment is energy efficiency.  In my previous article I discussed how the critical components of the WSHP works to deliver conditioning to the space.  Here I’ll discuss how energy efficiency is calculated, tested, and communicated along with measures that providers can take to increase the efficiency of their product. 

Energy efficiency is the measure of how much cooling/heating you get for each unit of energy put into the equipment...

How Water Source Heat Pumps Work

August 17, 2020

By Matthew A. Crump PE

Most people are familiar with a standard residential split air conditioning system.  It is split because the indoor system blows the cooled or heated air and the outdoor unit makes a lot of noise when it’s operating.  These two pieces of equipment are connected by piping that carries refrigerant between them.  The outdoor unit contains a compressor, outdoor coil, and fan.  During cooling the compressor will compress the refrigerant into a superheated gas, then force it...

How a Water Source Heat Pump Works: Thermodynamics 101

July 24, 2020

By Matthew A. Crump PE

In my previous article, located here, I discussed the benefits of selecting a water source heat pump system for your building.  The next few articles will discuss how the heat pump works.

The heating and cooling provided by a water source heat pump, and for that matter all refrigerant based conditioning equipment, is made possible by the refrigeration cycle.  Mechanical...

Seismic Shift: Nailor Terminal and Horizontal Fan Coil Units now certified for seismic environments

July 14, 2020
By: Matthew Crump, PE
According to the United States Geological Survey (USGS) there are 65,000,000 people living in an area that has a 10% probability of experiencing “Strong Shaking” due to seismic activity.  [Peterson, 2019] This area is represented by the yellow through red areas on Figure 1. And, population trends over the past 20 years have shown that this number is growing quite quickly. Almost 20% growth in the exposed population in that time frame. The need for...
