Does Your Space Deserve the Most Advanced Room Air Cleaner?
October 14, 2020
The American Society of Heating, Refrigeration, and Air-Conditioning Engineers (ASHRAE) is the leading organization focused on researching and guiding proper HVAC system design and construction for maintaining comfort, health, and wellbeing of building occupants. This includes controlling infectious disease contaminants in the air within a space. The ASHRAE Position Document on Infectious Aerosols (COVID-19) recommends that existing spaces have high-efficiency particle filtration paired with UV-C Lights (Ultraviolet light) to capture and destroy...
Constant Volume Regulators: What are they and how they help
October 6, 2020
Many obstacles will arise when trying to keep a building 30-50°F warmer or cooler than the outside temperature. The aim of the HVAC system is to keep the buildings’ inhabitants comfortable and healthy while considering system costs. When designing and installing multi-floor supply and exhaust systems, balancing can become an issue. Fan pressures and thermal stack effects can cause differences in how much supply/exhaust air each floor experiences. When spaces experience the incorrect amount of supply/exhaust air it can affect the...
Filters on Fan Powered Terminal Units
September 8, 2020
Summary
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 “clogged” with filtrants the pressure drop will increase. This...
Energy Efficiency: Water Source Heat Pumps
August 21, 2020
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. More efficient equipment utilizes less energy...
How Water Source Heat Pumps Work
August 17, 2020
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 through the outdoor coil. The fan draws the outside air through the...
