School District Chiller & Condensing Coil Maintenance

As the majority of the directors of zone of school 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 complaints of faintness and student an! d teaching body of occupant of building; it is a well establis! hed fact that an uncomfortable environment of interior does not support the process of teaching and training. While it Malayan of student and teaching body appears for periods of occupation, the penalty of energy occurs 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. To consider this realistic scenario: A refrigerator of 20 tons employed to cool the computer room of a building of administration of zone becomes clogged and needs cleaning; but because the department of maintenance is given soon and tending on other important subjects through the zone, they do not have ! the hour to carry out maintenance when it is necessary consequently; maintenance has put-with far for a not specified period. Thereafter, the remains load completely clogs rollings up of refrigerator having for result a second level of the failure which has a catastrophic impact on the zone and the budget of maintenance. Second failure of refrigerator of level (characteristics and implications of cost) that the compressor fails. The computer room tests the failure of computer due to overheating and the zone cannot reach discs of school, give access Internet the school buildings; stop communications of email between the administrators, the professors and the parents; the capacity of effects to treat the book of pay of the employees and the impacts reach information and the reports/ratios. In the refrigerator the failure runs can quickly still bring operations and communications of zone to a stand and can cause people of the important countries, the state and the federal dead! lines of report to miss. The use of the information processing! system of help is not deployed because they too would be prone to the failure under the conditions at high temperatures. The supply of a new compressor typically takes 2 or 3 days having for result the appreciably reduced administrative effectiveness during the time of breakdown of refrigerator. The replacement cost of compressor - installation of $7.500 compressors to cost - maintenance $4.000 cost overtime - the cost cleaning of $3.500 rollings up: $1.500 bus you can see, if the cleaning of rolling up and maintenance had been carried out before the first level of the failure, it aurait seulement coûté $1.500 ; cependant, parce qu'il a été reporté et l'opération a été continuée jusqu'au deuxième niveau de l'échec, les coûts se sont associés à la blessure de niveau du deuxième échec coûtant vers le haut la zone plus de $16.000 ; c'est onze fois le coût de l'entretien préventif qui aurait empêché l'échec en premier lieu ! - Note : ceci n'inclut pas même le coût énergetique addition! nel amenant à l'échec ni le coût administratif additionnel dû à l'échec de système. Maintenant, si vous pensez cela qui a la redondance de réfrigérateur est critique à cet endroit critique de « mission » que vous auriez raison ; cependant, les réalités d'aujourd'hui de la zone plaçant généralement ne permet pas le luxe de avoir le plein support de système par conséquent, le besoin des zones d'investir dans des pratiques en matière d'entretien et des technologies préventives diligentes d'économie d'entretien. Pourquoi les zones d'école reportent l'entretien sur des réfrigérateurs et Units.There de condensation sont beaucoup de raisons citées par des équipements et des directeurs et des directeurs d'entretien ; toutefois il est important de maintenir dans l'esprit qui indépendamment des raisons, quand l'équipement a besoin de mA intenance, deferring it for any reason will not change that fact. Do any of these reasons sound familiar?Budgetary Constraints - "We'll put-off the m! aintenance until next month so we don't go over budget". When ! you cons ider all of the risks associated with a system failure, deferring maintenance due to budgetary constraints is not usually a sound decision. When budgetary constraints are placed on the maintenance of "mission critical" equipment, the results can be catastrophic to the district and maintenance budget. Man Power & Time Constraints - "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 school districts have been forced to reduce staff and streamline operations to conform to the economic realities of their district due to failed school levy's, changes or reductions in state and federal funding, 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 technologies such as air intake coil filters should be evaluated. In short, investment 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 correctly" - this reason is especially common in districts 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 ha! te 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 protective outerwear should be worn to protect against coil cleaning chemicals 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 " time and 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 significantly 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 facilities directors and maintenance engineers 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.comArt! icle Source: http://EzineArticles.com/?expert=Randy_Simmonsstudent loan center
