Hospital Cooling Tower Case Study

The airborne remains put the Baptist that turns of cooling of is of hospital in the intensive turns of cooling of Care.Whether are used for process or environmental cooling, suitable maintenance of turn is critical to ensure the optimal execution by satisfying the requests for cooling of the service or the operation. The airborne remains which become drawn in turns of cooling are the major simple problem contributing to the clogging of system, the reduced execution, the downtime and the maintenance costs. When turns of cooling are not correctly maintained, the execution will suffer, having for result the increased temperatures of interior, a reduction of the levels of comfort of occupant including/understanding the reduced productivity of the employees; and it can affect the computer rooms and the equipment and the operations which they support. Moreover, when the turns of cooling fail in applications of cooling of process, it can bring the production to a halt of grinding, ! and the cost of lost productivity can stagger. The following history of war shows the kinds of problems which can occur with any tower of cooling (process and environmental applications of cooling) and in the way in which a hospital solved their problems of turn of cooling. The subjected equipment several modern medical buildings placing the offices of corporation of the system of care of health of Baptist as well as of the offices of doctor and other servicing equipment of health beside the hospital of Baptist is (BHE), of Louisville, KY, the areas carrying out the hospital for the oncology, cardiology, orthopedy and problem of Neurosurgery.The during 16 last years, controlling the cooling of the buildings had been a challenge due to the challenges of maintenance of two turns of cooling of VAT (rolling up of air of Baltimore). Gilbert Fister, director of properties for the buildings of the campus of BHE, was confronted to take the turns out of the operation for programmed ! maintenance twice a year, more, which had with the high season! al conce ntration of the airborne contaminants which became drawn in the turns, they required not-programmed maintenance dependent on the system clogging and obstructing. "In spring and the summer, the transitory ones, the needles pine and any other matter would seriously block our material fill and the sieves of basin and to start a series of other operational problems," indicated Fister. Although the turns of cooling of VAT are equipped with the systems of filtration of water, they required the supervising and cleaning weekly magazine and made little to protect from the remains to enter cooling water against initially. Moreover, they did not do anything to protect the fill material to obtain against blocked with the remains being drawn inside, having for result a reduction of thermal effectiveness like cooling water passed by the fill material. Moreover, the organic remains (the insects, pine upsets, seed of poplar, dirtiness of sheets and any other airborne matter) would gather ou! t of basin and would break up, having for result the preparing of dirty oil which supported bacteria proliferation, connected the sieves of basin and reduced to cool the effectiveness once circulated by the refrigerator. With much from occasions, the remains obtained by the sieve of basin, having for result the exhaust valve of solenoid being wedged in position of opening; this started automatic release of the chemicals of treatment water and prematurely drained the chemical reserve of treatment requiring of BHE to claim fillings of help. Moreover, when the exhaust valve stuck in position of opening, it had as consequence the loss of thousands of gallons of the water of make-up because the sump would not maintain water. In short, the system would fail. During programmed maintenance, the turns by practice were cleaned by using a disc of pressure and solvents of cleaning - most of work was concentrated on cleaning the fill material which had concentrations raised out of remai! ns of its surface. In year, literally of the thousands of doll! ars were spent to just keep of them the turns of cooling from the operation point of view and resound ecologically. Gilbert was not satisfied with the situation and was not presented to improve the requests of maintenance being placed on these important systems. The solution while consulting with their Gilbert contractor of maintenance realized that they had need for a solution which would prevent remains from entering the turns of R efroidissement en premier lieu plutôt que d'essayer de contrôler les débris par le passé il a obtenu po tiré Gilbert a recherché cette option et a contacté Air Solution Company de banlieue noire de commerce, Michigan, le principal producteur de la tour de refroidissement et des systèmes de filtre d'entrée d'air d'enroulement de réfrigérateur. À la différence de l'entrée d'air traditionnelle de filtres à air à air (utilisés généralement en air manipulant la filtration d'unité encaisse) les filtres montent à l'extérieur de l'ouverture de prise et sont spé! cifiquement conçus pour isoler les débris aéroportés sur l'extérieur de la tour de refroidissement. Les filtres sont construits avec résistant et non-électrostatique UV des médias de polyester enduits par vinyle qui résiste au moule et à la rouille, n'a jamais besoin changer et est facilement nettoyé en utilisant une brosse, balayent ou font des emplettes vide. Depuis leur installation en 1999, BHE a éliminé l'habillage de cambouis et n'a pas éprouvé obstruer de tamis ou de soupape d'échappement. En outre, ils ont réduit leur consommation chimique près plus de 50% et ont réduit leur consommation de l'eau de maquillage de 35%. Puisque les filtres d'entrée d'air gardent maintenant des débris hors du système, BHE n'a pas exigé le service non-programmé dû à l'encrassement de système - tho d'économie usands of dollars in labor and service cost. In short, Gilbert "hit a home run" in reducing the maintenance and operational cost associated with their cooling towers."Since the inst! allation of the Air Intake Filters, we now only inspect our to! wers mon thly and find little or no maintenance required versus our inspecting them weekly before the filters were installed and nearly every time finding a need for some maintenance work. Installing Air Intake Filters on our cooling towers has saved us countless dollars and has given me "peace of mind" knowing that we're now optimizing our operational efficiency and protecting the core of our cooling systems." Said Gilbert Fister.Water Treatment and Mechanical Service Providers Perspective? Most companies and institutions that outsource their HVAC system services do so as a means of reducing their cost of operations while improving system efficiencies. This typically entails establishing annual service contracts with water treatment and mechanical contractors to ensure scheduled maintenance intervals. But to truly optimize the cost savings, the system itself must be efficiently equipped so that the savings realized through not maintaining an in-house HVAC service team isn't lost to ! extraordinary and unscheduled service needs. In BHE's case, their water treatment service provider contracted for annual service and chemical replenishment based upon normal maintenance and operation. But when chemical consumption dramatically increased because the blow-down valves would get stuck open, it was the chemical service provider that wound-up eating the added cost during the contract period. Hence, when the Air Intake Filters were installed, both BHE and their water treatment supplier were winners. According to the service company used by BHE, "use of the Air Intake Filters have helped us to keep their cooling towers running optimally and has reduced our maintenance cycle time by nearly half. The advantage to BHE is that their towers are out of service for shorter periods of time during scheduled maintenance. Furthermore, it helps us free-up valuable service time, giving us greater flexibility to deploy our service team where they are needed most and to serve mor! e customers per day. Because the Air Intake Filters do such a ! good job of helping keep BHE's towers clean, they help us to optimize the profitability of our maintenance contract because we now only deploy resources at scheduled intervals and we have virtually eliminated unscheduled emergency maintenance at BHE.Benefits of Air Intake Filtration at BHE (recap)Stopped insects, pine needles, leaves, paper and other airborne debris from getting into cooling towers. Stopped clogging of fill material - enabling optimal thermal release. Helps prevent sludge build-up in basins. Stopped basin strainer clogging. Stopped clogging of blow-down valve. Reduced consumption of water treatment chemicals by 50%. Reduced consumption of make-up water by 35%. Improved chiller efficiency. Eliminated unscheduled downtime and maintenance service calls due to clogging and fouling. Reduced maintenance cycle time by nearly 50%. When it comes to maintaining cooling towers, it ultimately requires a team effort between the customer and the mechanical and water treatment ser! vice providers. Using Air Intake Filters in conjunction with a well managed water treatment program and scheduled maintenance program will ensure that cooling towers perform optimally, while helping avoid unscheduled emergency service.Air Solution Company developed and patented the first Air Intake Filter specifically engineered to mount to the outside of cooling towers and other HVAC equipment for purposes of stopping the debris before it entered into the system. Since that time, Air Solution Company has been manufacturing and has introduced a variety of other innovative filter systems including its new Fine Mesh Filter which is engineered for use on small and medium size refrigeration coils and machine fan intake housing units.
