While many are excited to emerge from a long and cold winter
and enjoy the rising temperatures that come with spring, not everyone loves the
shift in seasons. Facility managers around the country dread the season change
as it always brings lingering HVAC problems to the forefront. Every year during
the spring and fall as temperatures are changing, buildings around the country
work hard to adjust to the change in seasons as well. The HVAC systems go from cold
temps outside and constant heating of the building to cooling instead, or vice
versa. This dramatic change takes a toll on the building envelope and interior
and can make underlying HVAC problems that went unnoticed during one season,
suddenly very noticeable. Employees and paying customers alike are feeling the
discomfort of hot and cold spots, condensation dripping, A/C not kicking on
correctly, doors blowing open, and other annoyances.
These types of issues not only
affect the comfort for your customers in the facility, they can also lead to
long term maintenance and higher energy costs should they not be fixed quickly.
This is where having an independent 3rd party onsite to inspect the
equipment can assist. Hiring an independent company can help in identifying the
underlying cause of such problems and repair minor issues that may have gone
undetected for years. By having the facility inspected by a truly independent
company, facility managers can know that the information they are receiving
provides a truly accurate snapshot of their facility and is not biased or
swayed based on loyalties. You will get real results with accurate and
If you are experiencing any of these issues with the upcoming season change, it is recommended to have these issues investigated immediately. Prices begin to rise just as the temperature does in the summer, as construction demand is at its peak during this time. Seeing some of these issues in your building?

What did you do before coming to Melink?
Before Melink, I
was a student at the University of Dayton. As a student, I served three co-op
terms. Two terms were with Emerson Climate Technologies where I worked in the
A/C Scroll Compressor division. My third term was with Eaton Corporation where
I worked as a technical sales intern out of their Dallas, TX office.
What is your favorite aspect of working
aspect of working at Melink are the customers we get to work with. The fact
that we’re able to do business with biggest names in commercial restaurant and
retail speaks volumes about our offerings.
What do you like to do in your time off?
In my time off,
I like to exercise and cook (not at the same time).
Tell us something that might surprise us
Melink Solar & Geo recently became a national representative for SHARC Energy Systems, a company that has developed a series of products focused on recovering thermal energy in liquid waste such as sewage, laundry wash water, brewery tank cleaning water, etc. This energy is then transferred via a heat pump to create new hot water for either domestic hot water (showering and cleaning) or space heating hot water. These systems can also take the place of a cooling tower to allow heat rejection in the summer months without consuming precious water or requiring chemical treatment.
Why would MS&G want to promote these products?
First, this is a largely untapped source of thermal energy that is HUGE! In 2005, the US DOE estimated that 1,194,200 BILLION BTU’s are discarded annually down our drains in North America – probably much more nearly 15 years later. Note that if you burned natural gas to make that much heat at typical market costs, this untapped energy stream could be worth nearly $6,000,000,000! That’s a lot of zeros!
Second reason to add this to
our “toolbox of energy solutions” includes our mission to “electrify
everything” in a manner that is highly cost effective and
environmentally positive. This
technology is complementary to our other Solar PV and Ground-Source Heat Pump
offerings in meeting that goal. This
additional also complements our other divisions; Testing & Balancing,
IntelliHood (smart, variable volume commercial kitchen hoods) and PositiV (our
new building “health” monitoring system).
Recently we designed a geothermal heat pump system for a new 7 story/230 room hotel that is under construction in the USA Midwest. We observed that the heat pump system removed much more cooling energy than required for heating on an annual basis. One way to address this is to apply this type of technology to “pump” waste heat from the HVAC system into the Domestic Hot Water system to reduce the burning of natural gas, reduce energy cost and allow the heat pump system to operate more efficiently. We’ve proposed to provide a SHARC PIRANHA system to address this and depending upon the size of the system (5 or 10 tons) we could provide an annual energy savings of $4,000 to $9,000 with a CO2 reduction of 22 to 45 metric tonnes. This system could provide 27-54% of their annual hot water needs. Payback on the initial investment can be as short as 6-7 years.
We provided the conceptual design for a 235,000 square foot research facility proposed to be built in Ohio. They wanted to consider a ground-source heat pump solution for their nominal 1,000-ton cooling load. We looked at a full-size geothermal bore field that would cost approximately $5.3 million, then a smaller bore field with a cooling tower that would cost $3.0 million and finally, a VERY small geothermal bore field with a SHARC system tied into the city sewer for only $1.5 million! This offering allows us to provide better energy consumption than a full-size geothermal borefield or the cooling tower options with lower first cost, no water or chemical treatment for a cooling tower and ALL HVAC components safely underground or inside to reduce risk from damage from weather events or acts of terror.
continue to work with SHARC Energy to develop concepts that can enhance our
mission to change how we heat & cool buildings and provide hot water. These types of systems can be great for:
applications such as recovering heat from sewage or laundry, possibly large
commercial kitchens with a significant dish washing load as well
distilleries and wineries that use a great deal of hot water for cleaning that
is then lost down the drain
washes – also can be lots of hot water down the drain
buildings, college residence halls and senior living facilities – target size
of 50 to 400 residents is the sweet spot, but larger is great too!
swimming pools that have separate tanks for filter backwash water before it is
released to a city sewer
We are even looking at two municipal (large) snow melt systems in the Midwest that use natural gas to provide the needed heat. Converting these to municipal sewage heat pumps can significantly reduce energy consumption, cost and CO2 emissions.
