Healthcare Facility Chiller & Condensing Coil Maintenance

Because the majority of the equipment of care of health and engineers of maintenance know, suitable maintenance on the refrigerator and the units of condensation is critical with the effective operation and without breakdown. However when you combine the fact that the majority of the refrigerators and units of condensation are located in low places of the traffic and out of the sight (C. - with-D., behind buildings, hidden behind walls, on tops of roof, etc,) with the fact that the part of cleaning of rolling up of the process of maintenance takes unpleasant and time to charge, refrigerator and maintenance of condensation of unit is not one of work that the majority of the engineers of maintenance wait with interest. In the situations where the department of maintenance is occupied or with court of manpower, the cleaning of rolling up is likely to be deferred beyond the moment when maintenance is really required by the equipment. One generally knows it in all the industry of! the CAHT that even lightest clogging rolling up carries out to what can be described as first level of the failure which is distinguished by the following characteristics: First functioning principal pressure higher of compressor of failure of refrigerator of level (characteristics) (caused by high cooling pressure resulting from the flow of restricted air and poor heat exchange). Reduced capacity of cooling (caused by the poor flow of air by rollings up). Increased aspiration of kilowatt coupled to a reduction in the capacity of cooling of tonnage. The unit functions longer and works harder to carry out the regulated points of the temperature. The compressor continues to make a cycle with far and above under the high principal pressure (the compressor is subjected to a constraint in dirty states of rolling up - the system overheats). The refrigerators suffering from the states of pressure of high-head pass the impact length in the form of employee and faintness and felt s! orry for of patient, a reduction of the productivity of the em! ployees and energy costs higher. As long as rollings up remain dirty and the flow of air is reduced, the penalty of energy will occur during every hour of operation (during the part-load and the operation full-load). Unless you supervise the aspiration of kilowatt of refrigerator with a system of management of energy or with a separate regulating device, you will most probably get information about the problem when the weather is hot and you cannot maintain the environmental water alarming and/or temperatures, when you see your consumption energy to go up out of arrow or when your compressor fails. In the applications where a refrigerator supports the critical infrastructure of systems such as computer rooms, rooms of operation and critical equipment of care, clogged rollings up can have like consequence the overheating and the failure of computer equipement, access of effect to the patient care, invoicing and the information of purchase, programmes of operation of impact and carry ! out the comfort and the quality of interior of air - the impact can be enormous. To consider this scenario: A refrigerator of 20 tons employed to cool a room of computer control of a hospital becomes clogged and needs cleaning; but because the department of maintenance was given soon, they did not have the hour to carry out maintenance when it was necessary consequently; maintenance is deferred for one not specified period. Thereafter, the remains load completely clogs rollings up of refrigerator having for result a second level of the failure which has as consequence a catastrophic failure of computer that the impacts automated of the processes of businesses through the service. Second failure of refrigerator of level (characteristics and implications of cost) that the compressor fails and cooling in the computer room is lost. The computer room overheats having for result the failure of computer. Although the back-up systems of computer are in place - they are also vulnera! ble to overheating because the system of cooling of room compu! ters is falling. The coolers of spot are available but are not conceived for the full thermal load of the computer room. The supply of new catches of a compressor 2 days having for result a significant increase in employee work the effort and a reduction of total effectiveness and productivity (note: the reductions of effectiveness will change to depend on the systems and the affected processes of work). The increased employee cost overtime because of the reductions of effectiveness of system - the low preserving evaluation $150.000 + ($75.000 + newspaper). Cost de remplacement de compresseur - installation de $7.500 compresseurs coûter - nettoyage de $4.000 enroulements coûté : $1.500 car vous pouvez voir, si le nettoyage d'enroulement et l'entretien sont exécutés avant le premier niveau de l'échec, il coûterait seulement $1.500 aux systèmes de service de subsistance fonctionnant sans à-coup ; cependant si l'entretien est reporté et l'opération continue jusqu'au deuxième niveau de! l'échec, les coûts liés au deuxième échec pourraient facilement remontage coûtant les compagnies finies de $100,000.Why pour reporter l'entretien sur des réfrigérateurs et Units.There de condensation sont beaucoup de raisons citées par des équipements et des directeurs d'entretien ; toutefois il est important de maintenir dans l'esprit qui indépendamment des raisons, quand l'équipement a besoin de l'entretien, le report de lui pour aucune raison ne changera pas ce fait. Quelconque d'entre ces raisons semblent-elles familières ? Contraintes budgétaires - « nous mettons-au loin l'entretien jusqu'au mois prochain ainsi nous n'allons pas au-dessus du budget ». Quand vous considérez tous les risques à des affaires liées à un échec de système, l'entretien de report dû aux contraintes budgétaires n'est pas habituellement une décision saine. Quand des contraintes budgétaires sont placées sur l'entretien du « processus et soulagent » l'équipement critique, les résultats ca n be cat! astrophic to the facilities and maintenance budget. Man Power ! & Time C onstraints - "We'll get around to cleaning the chiller as soon as we can - we have too many other things to do right now". This reason for deferring maintenance is more common today than ever before. Why? Because businesses & institutions have been forced to reduce staff and streamline operations to conform to the economic realities of their business, or they cannot find qualified personnel. This places additional demand on maintenance engineers because they now have to do more with less. If chillers and condensing units support mission critical operations and facilities, then maintenance of those systems should be near the top of the TO DO LIST even when the maintenance department is busy or short handed. To help improve maintenance efficiency and reduce the time required for performing the maintenance task, the maintenance should be outsourced to a reliable service company or maintenance reducing technologies such as air intake coil filters should be adopted. In short, inv! estment in technologies that can optimize operational efficiency and reduce the maintenance effort should be considered in lean maintenance staffing situations. Maintenance Complexity and Knowledge Constraints - "Maintaining this equipment is very difficult - we don't have the skills to maintain it properly" - this reason is especially common in companies using advanced mechanical systems. Maintenance workers must be trained to properly maintain them or, the maintenance work should be outsourced to a service company that is knowledgeable about the maintenance process. Unfriendly Maintenance Process - "We hate cleaning chiller and condensing units because it's a dirty job - we get dirt and debris all over us when we power wash the coils - we'll clean the coils later". Although cleaning coils are in fact a dirty job, it is not a sound reason for deferring maintenance. When cleaning coils, proper safety equipment including eye and respiratory protection, rubber gloves and prot! ective outerwear should be worn to protect against coil cleani! ng chemi cals and possible mold or bacteria problems that can pose a health hazard. As an alternative, air intake filtration systems that isolate the debris on the outside of the coils where it is visible and easy to clean using an ordinary broom, brush or shop vacuum can reduce the "hassle factor" associated with this important maintenance task. The list of reasons for deferring maintenance can go on and on but one thing is clear, deferring maintenance on HVAC equipment can be risky and can increase the odds that a system failure will occur; and when it does, it will usually cost more than the cost of the maintenance that could have prevented the failure in the first place.In the end, the decision for performing or deferring maintenance on HVAC systems fall squarely on the shoulders of the maintenance and facilities directors as they balance their maintenance and budgetary decisions, recognizing all the risks involved.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.Air Solution Company Randy Simmons is with Air Solution Company, author of articles can be reached at http://www.airsolutioncompany.comArticle Source: http://EzineArticles.com/?expert=Randy_Simmons
