Tips on How to Service a Chiller System

The comfort one gets in place determines how long they can spend in that place. Homes are the places people spend most of their time. After work, one needs a place they can relax as they wait for the next activity in the following day. It is a place one can interact with family and friends. It provides privacy and freedom to do what one feels makes their life more comfortable, which leads to better living conditions. Consequently, homes need to be well furnished and maintained. They need to be equipped will all that makes the life of the households better off. Air conditioning is among the things that make homes nice places to be. As such, it ought to be properly functioning at all times to provide the desired conditions in the house. The air conditioners need to be of good quality and well maintained.

Chiller systems are types of conditioners used in both home and commercial setups. The air conditioners use chilled water to cool the air inside the rooms. The system is set in such a way that the chilled water absorbs the heat from the air indoor, and the heat is transferred to the air outdoor. The process continues until all the air inside is cooled thereby providing cools temperatures inside.

Chiller system requires good servicing to serve the premises properly for a considerable duration of time. First, you need to maintain a daily operating log. The operator of the system should document detailed and accurate log. The information recorded will be used to check deviations in performance, which is an excellent way of detecting problems whenever the machine develops some. The data recorded in the log will help the operator to analyze the performance of the whole system thus can take the necessary correction measures wherever need be. The data recorded can be compared with the data provided by the manufacturer of the levels that the system should have while operating properly.

Another thing that is done to service the chiller system is keeping the tubes clean. If the heat transfer, efficiency is not up to the standard it can significantly lead to the malfunctioning of the chiller system. The chilled water in the tubes is responsible for absorbing heat from indoors as well as transferring the heat from to the air outdoor. As such, if the tubes are covered by mud, algae or dirt generally, the transfer of heat from air indoor to the air outdoor will be affected. The implication is that the system will not be able to cool the air indoors as expected. To avoid such circumstances, the operator of the chiller system should always ensure that the system tubes are clean to facilitate heat transfer.

Cleaning of the chiller system tubes can be either mechanical or chemical. Mechanical cleaning of tubes helps to remove algae, sludge, mud and loose materials from the tube. The cleaning can be done through brushing or flushing of clean water. The operator should consider the cleaning recommendations provided by the manufacturer. In chemical cleaning, scales are removed. The operator of the chiller system should ensure that they make adequate consultations, either from the manufacturer of local sellers of cleaning chemicals, to ensure the most appropriate chemical is used.

Servicing of the chiller system also involves ensuring that the system is leak-free. Though it may be hard to have a perfectly non-leaking system, it is prudent to make sure that the whole system is not leaking. Although the system is composed of low-pressure compressors, often non-condensable materials are trapped in the condenser thereby increasing the pressure inside. High pressure then results in leakage in the system. The leakage attracts dirt to the system thereby compromising the efficiency of heat transfer. Moreover, moisture can as well create acids, which may corrode the windings of the motor as well as bearings. Such acids end up creating rust that is then trapped in the heat-exchanger tubes. When a substantial amount of rust is trapped, the efficiency in the transfer of heat is adversely affected thus and hence the efficiency of the whole system.

Water treatment is crucial in the servicing of the chiller system. The operator should thus sustain the correct water treatment. Most of the chiller system use water for the purpose of heat transfer. As such, the water should be properly treated to prevent corrosion, scale as well as the growth of organisms such as algae. It is recommended that a one-time chemical cleaning be done when the water system is closed and connected to the evaporator. Open chiller system uses condenser water systems that are connected to the chiller condenser. Such systems require regular water treatment to reduce the effects of the local water, which may lead to the inefficiency of the system. Poor water treatment is often indicated by the presence of scale.

Similarly, the operator of the chiller system should analyze the refrigerant and oil. The analysis helps in the detection of chiller-contamination problems early in enough to avoid their becoming serious. The testing involves spectrometric chemical analysis that aids the determination of contaminants such as acids and metals, moisture, among others. Such contaminants affect the efficiency of the system. The tests can be done by a qualified chemical laboratory technician whose specialization is dealing with such systems.

Besides, the operator should check the operation of the starters as well as motors. The check involves examining the safety and sensor calibrations on the microprocessor controls. Electrical connections, worn contacts, wiring, and switchgear should also be checked. One should also ensure that there is proper insulation; motor windings are okay not forgetting to check whether the shaft seal of the open drive motors for leaks of the refrigerant. Moreover, the cooling air vents in the motor should be kept clean to ensure efficiency in the heat transfer.

In conclusion, installing which system or machine is always a milestone in providing the desired output. However, if the systems are not properly serviced, their significance continually decrease and eventually render them useless. To avoid high costs of having to replace such systems that are supposed to be long lasting, proper servicing should be ensured.
