Chiller systems are designed to cover a broad range of applications. So it is important to keep maintain the chiller AC system. In this PPT, you will get to know how to increase chiller efficiency.

OVERVIEW The efficiency of chillers ac has increased significantly in the last decade mostly because of the introduction of new refrigerants as well as microprocessor control along with better motor and compressor design. But high-tech chillers come with more precise tolerances, meaning maintenance and repair are more essential than ever to keep them functioning at their best.
Here, you will get to know five facts about Hitachi aircon units. Chiller AC system performance is highly dependent on operating conditions. Full-load performance isn’t an accurate measure of overall performance since chiller plant operations rarely run at full-load. Part load performance is essential to the overall good performance of the chiller plant. Several variables affect chiller efficiency. Below are 10 guidelines to keep your chiller in good shape.
MAKE SURE TUBES ARE FREE OF DIRT Heat transfer is the biggest single impact on the performance of chillers. Large chillers may include greater than 5 miles of the condenser as well as Evaporator tubes, and therefore the ability to transfer heat efficiently is essential for keeping the efficiency of your chiller. The efficiency of the chiller decreases dramatically as tubes get fouled. Minerals scale, mud, algae, and various impurities, cause thermal resistance to increase and decrease overall performance. The contaminants build up on the water surface on heat transfer surfaces, both in open- and closed-loop systems. The process of fouling is gradual as time passes, based on the temperature and quality of the water that is used.
TREAT CONDENSER WATER Condenser water loops that use a free cooling source, for example, atmospheric cooling towers require water treatment to stop the formation of fouling. The effects of corrosive conditions, such as Sand flowing through the tubes at a high speed can pit the tubes, reducing their effectiveness of the tube. In the absence of treatment, water may damage pipes, tubes, and other types of materials.
REDUCE THE TEMPERATURE AT WHICH WATER IS POURED INTO THE RESERVOIR. Reducing the temperature of the condenser’s water can enhance the efficiency of the chiller. For certain systems in the building, operators are able to lower the chilled water set point in order to eliminate air handler problems like dirty coils. Be wary of this method that may halt the symptoms, but will not fix the issue. The chiller is forced to work harder to achieve the same effect of cooling.
CONTROL WATER VELOCITY The rate of flow must be controlled precisely, since the insufficient flow decreases the efficiency of chillers, leading to laminar flows. The recommended flow rate is generally about 3 feet every second. But, a too high flow rate can cause vibration and noise, as well as tube erosion. The highest recommended flow rate is usually approximately 12 feet every second.
