In this broadcast, I am joined by Tomas Novillo, Director of Strategic Accounts, Nyle Water Heating Systems, to show how Hot Water Heat Pumps work.

We also discuss two concepts we keep hearing more often, Electrification and Decarbonization. Like it or not, that seems to be the way segments of the HVAC industry are heading.

The manufacturing community is starting to adjust, and we are proud to bring you this Live event, Heat Pump Water Heaters, Just the Basics. We will discuss how Heat Pump Water Heaters can be applied in commercial and residential applications and their role in the movement toward electrification.

Presented by Insight Partners and Nyle Heating Systems. Nyle Systems is a growing, innovative company that develops, manufactures, and sells heat pump-driven, energy-saving products. Specifically, they build industrial equipment for Lumber Drying, Food Dehydration, and Heat Pump Water Heating.

The product design and manufacturing facility is in Brewer, Maine, just across the river from Bangor, central Maine's economic and cultural center. They are firm believers in the need to build a more sustainable future, including the urgent need to reduce emissions. To switch from fossil fuels to electricity based on renewables, the world requires the electrification of many processes, and that is where Nyle focuses.

Thank you!

This podcast discusses the difference between Relative Humidity and Dew Point. This is an audio version of our live stream presentation on LinkedIn and our YouTube channel (Insight Partners HVAC TV). 

Here is a quick summary of the content. 

Relative Humidity: Not a good measure of water in the air (absolute humidity). RH is the percentage of how much moisture is in the air vs. how much it can hold. It answers the question “how full is the container”?

Dew Point: The atmospheric temperature below which water droplets begin to condense and dew can form. This is an accurate measurement of water in the air (humidity). We also look at Dry Bulb, Wetbulb (Illustrating with a Sling Psychrometer), Humidity in Grains/LB of dry air.

We thank you for listening!

In this podcast, I discuss the difference between a Copeland Digital Scroll Compressor and a Danfoss Variable Speed Compressor. These two HVAC modulating scroll compressor technologies accomplish similar results but are constructed differently. 

Watch LIVE Video Here: https://youtu.be/rH-VqoUvtC0?t=38

The Copeland Scroll Digital offers compressor modulation from 10-100 percent, allowing cooling systems to automatically adjust capacity as needed while reducing energy consumption. This scroll technology allows for precise HVAC system control, is more efficient than on/off compressors, and allows for almost continuous operation during dehumidification modes. Variable-capacity control is accomplished by timing the compression by engaging and disengaging the top scroll while motor speed remains constant. Advantages are efficiency, precise control, very low turn down to 10%, and constant velocity refrigerant allowing for effective oil return. For some of the compressor sizes, the "modulating" can produce unwanted noise. Special considerations for location and attenuation are recommended. 

Emerson’s Copeland Scroll Variable Speed compressors are designed with AC drive controls that modulate the compressor speed. This compressor speed modulation allows for precise capacity control. Advantages are efficiency, low acoustical characteristics, and precise control. Special considerations are required to ensure oil return which usually prohibits low turndown capabilities. Usually, the minimum allowable turn down is in the 10-25% range.  

Thank you for listening and please let me know if you have any questions!

Noise is a topic that plays a major role in any HVAC system yet it is a topic that is either misunderstood or not very well understood in the HVAC world. People constantly confuse key terms, definitions, and commonly rated values. 

Some examples of those terms are sound unit dB vs. dB(A); HVAC Sound Pressure vs. HVAC Sound Power; AHRI 260.2011 vs. AHRI 260.2017, A-Weighted Sound, to name a few.

So, in this course, we will go back to the basics of sound where we will define commonly used key terms, review the concepts of acoustics and frequency, understand the difference between sound pressure and sound power, and review how sound is measured in the HVAC units. We will wrap up with some case studies which will help to determine how room construction and unit construction can affect the NC (noise criteria) rating of a given room.

We will also show real-life examples of mitigating HVAC Equipment Noise.

What is the difference between Sound Power vs. Sound Pressure in HVAC Systems?

AHRI defines SOUND POWER as ACOUSTIC POWER, which is, in a specific frequency band, the rate at which the total airborne sound energy is radiated by a source, measured in watts.

In this episode, I discuss the importance of knowing the difference between Hot Gas Bypass and Hot Gas Reheat. 

Check out our YouTube Channel for a video version of this discussion: https://www.youtube.com/InsightPartnersHVACTV

HOT GAS REHEAT uses the high pressure, high temperature, compressor discharge gas to reheat the air leaving the evaporator coil. This is achieved by running the gas through a hot gas reheat coil using hot gas reheat valves. Hot gas reheat is typically used in dehumidification modes to meet the desired space sensible temperature set point. Modulating hot gas reheat, the more advanced form of reheat, allows us to precisely control the HVAC system leaving air temperature. As opposed to the older style electric reheat, which works well but wastes a lot of energy. Advances in HVAC controls and technology in HVAC systems over the years have made hot gas reheat very popular.

HOT GAS BYPASS provides an artificial load on the evaporator by introducing a portion of high pressure, high-temperature gas to the evaporator/suction side of the system. An inexpensive and simple way to keep the HVAC system running without freezing the coil but a huge energy waster. The hot gas bypass valve is old technology used on a limited basis today quickly being replaces by modulating compressors or variable capacity compressors. 

This episode is an audio version of our most popular online event, How To Read A Psychrometric Chart.  You can watch the video version here anytime here > https://youtu.be/b4IVoVP2eeo.
