AC Units Cooled By Well Water Re: AC Units Cooled By Well Water Phoenix Home Inspections Phoenix Home InspectorArizona Property InspectionsWhat you describe is what an hvac tech will know by slang as a "pump and dump" system. People nowadays favor calling it a geothermal system (that term might be more familiar to home inspectors), but it's essentially just a water cooled condensing coil versus the traditional large air cooled condensing coil. This may be straight AC, or it may be a heat pump. The quality of the water sorely effects the lifespan and the operating efficiency of the condensing coil heat exchanger. Paul as Mark stated they are probably water cooled condensers from the well source but being the non-trusting sole that I am I do not necessarily believe what I am told by someone going on hear say. The units could also be glycol not likely but could be. I would determine the cooling medium on site. Water cooled condensers are high maintenance required to be acidized periodically to reduce corrosion if not, they will create high head pressure similar to a matted over air cooled condenser.

Its late had a 5k home with 4 A/C units and furnaces today Good night all and you too John Boy could be water source heatpumps. David that was the point I was pressing the cooling medium can and does vary between MFG's all doing the same thing changing the state of Freon from a hot vapor to a liquid does not matter how it is done. In my reports I just state the type of cooling medium and no way to do this unless on site. As for producing hot water for domestic use, why not the compressor produces a hot vapor and could be routed through an heat exchanger designed for the use. I have not observed a unit of this nature but knowing the refrigeration principal I could trace the lines and tell you what was happening at the different stages and or configuration. Hi Greg clue me in are you stating the units you see do not use Freon but water as the medium explain please. Yes they use water and not freon. Most of them that I see are over 30 years old. I am still confused what I was reading in your links just tells me that the condenser is water cooled not that the unit does not use freon.

Have you actually opened up one of these units. Just trying to find out if someone else is using a system I have never heard of, still young enough to learn up here in the sticks Thanks for your responseStoring heat may be the last thing you think of when turning on an air conditioning unit, but one model takes advantage of the sweltering weather to heat water while cooling the air. The aptly named Air Conditioner Water Heater, or ACWH, from Hotspot Energy has a condenser unit that sits outside of the building, collecting heat that the air conditioner compresses and expels from inside. The heat passes through a copper heat exchanger that connects to a home or building’s hot water tank. According to the company, the unit can cool a 1000-square-foot room and heat about 100 gallons of water per day. At its peak, the ACWH can provide 18,000 BTU, or 1.5 tons of cooling using 1333 watts per hour. Heating water while cooling a building can help save energy, since the heat recovery process eases the load of the air conditioner.

The unit has to be installed relatively close (ideally within 150 feet of) the water heater, however, and only heats water when the air conditioner is running and there is enough hot air to warm the water. fan in ac unit not workingUsing the unit on a mild summer day won’t make a significant dent in water heating costs, but it could have an impact for homes with multiple residents who use hot water throughout the day to shower or wash dishes.how to hang a window ac unit HotSpot Energy, which makes the ACWH, sees buildings as large solar thermal collectors, ripe for gathering heat. places that sell ac unitsAlthough the unit can be installed anywhere, it was designed with the southern U.S. in mind, where many residents use air conditioners during spring and fall, in addition to summer.

Commercially, the company envisions restaurant kitchens, laundromats and server rooms benefiting from their technology.In June 2000, the Government, with the support of EMSD and other bureaux/departments, launched a scheme for wider use of fresh water in cooling towers for energy efficient air conditioning systems (FWCT Scheme) for non-domestic buildings. The FWCT Scheme was launched as a pilot scheme for application in initial 6 designated areas in Hong Kong. With its acceptance by the trade, it has changed its pilot status to a standing one from June 2008. A recent review was completed in September 2010 to streamline application procedures and requirements of the FWCT Scheme. Owners of non-domestic premises are encouraged to use water-cooled type (such as fresh water cooling towers) instead of air-cooled type for their air-conditioning system for energy efficiency. They are encouraged to apply for participation in the FWCT Scheme for their fresh water cooling towers installations.

The updated location plans of the designated areas for application are listed at the following: For premises located outside the listed designated areas, applications for joining the FWCT Scheme for their fresh water cooling tower installations are also welcomed and will be considered on a case-by-case basis in consultation with WSD on adequacy of fresh water supply. Addition /extension of designated areas will be considered as appropriate with regard to the applications. The requirements of application and operation of the FWCT Scheme are detailed in the following documents: To promote the proper use of water-cooled air conditioning systems for energy efficiency with regard to the environment and health issues, a set of Code of Practice for Water-cooled Air Conditioning System was promulgated in July 2006 to provide guidelines for the cooling tower design, installation, testing, commissioning, operation and maintenance. The Code of Practice comprises three parts:- Part 1: Design, Installation and Commissioning of Cooling Towers [PDF format (609KB)] Part 2: Operation and Maintenance of Cooling Towers [PDF format (292KB)] Part 3: Water Treatment Methods for Cooling Towers [PDF format (333KB)]

Guidance Notes on Code of Practice for Water-cooled Air Conditioning Systems (November 2011) (Rev. 1) [PDF format (429KB)] has been promulgated in November 2011. It will help readers to have a better understanding on the requirements of CoP(WACS) and facilitate designers of cooling tower installations to meet the requirements. All applications for participation in the FWCT Scheme shall comply with the above Code of Practice for Water-cooled Air Conditioning Systems and guidance notes. Further, all cooling tower installations under the FWCT Scheme shall also comply with the requirements stipulated in the Code of Practice for Prevention of Legionnaires' Disease (2012 Edition) [PDF format (1.48MB)] published by the Prevention of Legionnaires' Disease Committee. The owners of cooling tower installations should maintain proper conditions of the fresh water cooling towers to minimize contamination and nuisances to the public. A guideline on Good Operation and Maintenance Practice of Fresh Water Cooling Towers for Air-conditioning Systems [PDF format (3.17MB)] is compiled based on Part 2 of the above Code of Practice for easy reference.
