How Water Source Heat Pumps Work

How Water Source Heat Pumps Work
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 coil so that the superheated gas cools.  The refrigerant flows to the indoor unit that rapidly expands the high pressure cooled liquid to create a low-pressure low temperature gas that enters the indoor coil and the indoor fan… Read more

How a Water Source Heat Pump Works: Thermodynamics 101

How a Water Source Heat Pump Works
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 equipment pressurizes and cools refrigerant to achieve the desired temperatures needed to heat or cool the air in a space. Gas and Liquid substances generally follow the relationships explained by the ideal gas law:  With this equation, if you know the pressure, volume, and amount of substance you can calculate the temperature.  This also provides the relationship between Pressure, Volume, and… Read more

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

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 equipment and construction methods that can withstand these threats while keeping occupants safe is increasing every year. Recognizing this need, Nailor has recently undergone the process of certifying its Terminal Unit and Horizontal Fan Coil Product Lines as acceptable in these regions.  This process is governed by the AHRI Standard… Read more

The best HVAC system for High Rise Condo developments

When designing a multi-tenant residential or hospitality hi-rise building there are several different choices for the air conditioning system.  The system selection must consider how the decision affects all the interested parties over the life of the building, including the developer, contractors, building management, owner, and/or dwelling owner in the case of a condominium.  Ultimately, all these groups have common goals, but how they prioritize these goals may differ.  The developer is concerned with return on investment, the contractor is concerned with ease of installation and reduced call backs, the building management wants to reduce maintenance, and the owner wants a reliable and comfortable space. An easy choice to meet all these needs is a Water Source Heat Pump… Read more
