    Superheat and Subcooled Levels for Water Source Heat Pumps

    This paper evaluates and analyzes the superheat and subcooled levels for water source heat pumps. As per the non-ideal refrigeration cycle, each cycle has a certain amount of superheat in the suction line and a certain amount of subcooled liquid in the liquid line. By evaluating the level of measured superheat and subcooled levels for a known correctly charged system, we can document and publish the results for internal and external use. By connecting temperature gauges to the suction and liquid lines of a system, the superheat and subcooled levels of the system can be found relatively quickly. Charge can be declared to be correct if the values of the superheat and subcooled levels match those of the lab tested values.

    Energy Recovery Technologies

    Energy recovery is a common solution to provide comfort ventilation for commercial and institutional applications. Due to the large variety of technologies, there is a need to differentiate the advantages of each. Three of the most common technologies in the energy recovery market are:

    • Total Energy Wheel
    • Total Energy Core
    • Sensible Aluminum Plate

    Although ASHRAE 90.1 drives when energy recovery should be applied, understanding the composition, design and total efficiency of these technologies can add to an educated decision on which technology will be the best for an application.

    Healthcare and Energy Savings: An HVAC Approach

    For hospitals and other healthcare facilities, power systems can never be allowed to flatline. It is this "always on" setting that keeps patients alive, provides reliable access to vital electronic health records, and ensures that medical staff can perform life-sustaining work 24/7. But all that energy expenditure comes at a steep price.

    Inside Matrix Variable Frequency Drive Technology

    From the beginning, VFDs have been used to control the speed of electric motors, which consume approximately 25% of the world's electrical energy in industrial and commercial applications. By definition, VFDs enable a user to operate a motor at any commanded speed, as opposed to running across-the-line at a fixed speed. This variable speed control saves signifcant energy and also lessens the wear and tear on mechancical couplings, such as gear, belts, and pulleys.

    Greenheck Project Profile: Wausau Curling Center, Wausau, WI

    The sport of curling is a strategic game like chess, with an element of skill and experience. Played on ice in an indoor controlled environment, temperature and humidity are critical to setting ice speed and the amount of "curl" the stone will incur. Another design challenge was dealing with the variable loads without over-ventilating which would lead to extremely high utility bills.
