Politisite is scheduled to do an on site interview with the Aqua Products President , John Seppamaki, regarding new technology in place of conventional air conditioner units. Here is an excellent chance to get an inside look at a green technology company located in South Carolina.
Reverse Cycle Chiller(TM) Goes Green
Aqua Products Co., Inc.
Newberry, SC 29108
Now With an Optional Heat Pipe Solar Collector
Aqua Products Company, Inc., Prosperity, South Carolina, introduces the new GREEN Reverse Cycle Chiller(TM) (RCC) for heating your home or office with hot water or air conditioning with chilled water. The RCC is will also work in conjunction with the Aqua Solar Heat Pipe (APCHPL16) built with 16 high efficiency evacuated vacuum tubes to produce free hot water.
According to John W. Seppamaki, President of Aqua Products Company, “The days of affordable heating our homes or businesses are coming to an end. We are challenged to not only build new green products for the Heating & Air conditioning Industry (HVAC) but we must also develop the most efficient, flexible systems that will incorporate affordability of operations with the comfort equal to fossil fuels. We are the pioneers of the Reverse Cycle Chiller(TM) (RCC) and are proud to be a York® UPG partner. We would like to introduce the new MODEL RCS built around the York® high efficient air source heat pump. The RCS is now available using the new green, R-410A refrigerant and also carries a higher COP rating. We can now merge both our RCS heat pumps with our APCHPL16 solar panels giving us a renewable energy assist.”
The first part of this system uses one of the Reverse Cycle System models. The RCS is able to produce chilled water for air conditioning and dehumidification in the hottest days of summer. Then in the cold days of winter it provides hot water for comfort heating. It has been called the hot air heat pump and the radiant floor heat pump. You can choose to use this hot water for radiant floor heating, forced air central systems, multiple ductless fan coils or use a mixture of all of the above.
The RCS is a highly-efficient way to heat hot water to a maximum of 115°F at costs competitive with gas fired systems. The RCS uses electric compressor technology to produce low cost hot water. The amount of useful hot water delivered by the RCS is greater than the amount of energy it takes to create it. The hot water Coefficient of Performance (COP) of the RCS is the ratio of useful hot water output (Btuh) compared to the total Kilowatt (1 KW = 3413 Btuh) it takes to produce it. The COP
range of the RCS is from 2 to as high as 6 when operating under favorable conditions. The maximum COPs of gas, oil or electric resistance heating is always one.
What makes the RCS different is its ability to allow the York® heat pump to be sized to the heating requirements (load) of the home. Most heat pumps cannot be sized to the true heat load because the air conditioning load is normally smaller and this could cause short cycling when using to air condition the home. This means that most standard DX heat pumps require supplemental electric resistance heat strips to help match the deficiencies by attempting to provide all of the heat. This is like buying half of a furnace then going to Wal-Mart to purchase small electric heaters attempting to keep warm when cold weather requires the need for the other half that is just not available. Because the RCS can be sized to the heating requirements of your home, it is able to produce hot, comfortable air the majority of the time in the winter with back-up heating required only during emergencies on those few extremely cold winter days that need extra heat.
The RCS heating and air conditioning systems work by sending water through the same two insulated pex water pipes to provide the energy needed for comfort heating and cooling. The RCS uses the high efficiency air source heat pump and converts its energy into an affordable total electric comfort system. We also can install one of our Aqua Solar Tanks with two optional independent water circuits which allows us to divert our stored hot water energy to assist in heating our potable water or used with our RCS for space heating. The RCS can also be used with other alternative energy sources such as wood fired boilers, fuel cells, etc…
The purpose of the storage tank is to act as a buffer and serve as a “thermal flywheel” that assists the system during times of low output and helps shorten defrost cycles without taking heat from the building. This design will also insure that the RCS will not short cycle during the air conditioning cycle.
Hot water radiant floor systems are growing across the world and have become known as one of the most comfortable and cost efficient ways to heat a home or
office. The RCS has made it easy and economical to provide an affordable total electric home by adding its ability to provide hot water for radiant floor heating
using an air source heat pump. The RCS is designed to operate normally down to 17° F outdoor temperatures without the need for back-up heat. By adding an RCS
to a radiant floor system gives you the ideal comfort systems for cold climates. The RCS is able to produce up to 115° F hot water; but just as important, it can
produce down to 40° F chilled water for great air conditioning and dehumidification. Both heating and air conditioning sides can provide true zoning by using
standard or high pressure air handlers and/or ductless fan coils and/or radiant heating or combination of all of the above.
The advantage of using water with an air source heat pump gives us the unique ability of adding multiple single phase power RCS modules for larger loads like 10, 15, and 20 tons. Staging is accomplished with a simple adjustment of the built in water temperature controller standard in each RCS.
The second part of the system uses the Aqua Solar Heat Pipe (APCHPL16) hot water collectors. The Aqua Solar Heat Pipe collector consists of a series of 16 glass vacuum tubes with high intensity film and contain a heat pipe in each tube to absorb solar energy even on a cloudy day. This heat energy is then transfered into a water glycol solution being circulated from our Aqua Solar Tank (AST). The free stored hot water/glycol can be used to heat water circulating through both of our independent AST circuits and used where most beneficial depending on the time of the year. Each vacuum tube is round by design and can track the sun which allows for hot water production from mid morning till mid afternoon. Just two of the new collectors are capable of producing 80 gallons of hot water a day which used to take
three of the old style panels under favorable conditions.
By adding the solar generated hot water to the Aqua Solar Tank gives us several options on how we can use this free hot water. First option: we can use the free hot
water during the heating season to help supplement the RCS with additional free solar heat. Second option: we can use this free hot water during summer months to
heat most of our domestic hot water or it could be used to assist in the heating a pool or spa.
Aqua Products Company is starting its first pilot programs by adding a new model of our RCS with flex sizing. The new models are the RCS-24/36 = 2 to 3 ton capacity and the RCS-48/60 = 4 to 5 ton capacity. This program is under way in the states of Oregon, Washington, Florida, North Carolina, South Carolina and Tennessee.
Aqua Products Company, Inc. is in the process of training a limited number of York® contractors in select areas to market and install this new hybrid system.
