Because an industrial chiller works on a continuous cycle, this low-pressure liquid is then transferred back to the evaporator where the whole cycle will repeat itself. During this process, the refrigerant changes from a high-pressure liquid to a low-pressure liquid. The high-pressure liquid travels to the evaporator through the expansion valve. After the gas leaves the condenser, the refrigerant changes into a high-pressure liquid. Because the heat is blown outside of the chiller, it is ideal to place the chiller outdoors or in a large indoor location that will not be affected by the excess heat. While in the condenser, heat is removed from the chiller by being blown outside through fans on the side of the condenser. The gas then leaves and goes to the air-cooled condensers. Next, the evaporated refrigerant travels to the compressor where the low-pressure gas is compressed into a high-pressure gas. Liquid refrigerant evaporates as it moves over the evaporator tube, creating a low-pressure gas. Heat is transferred away from the water using the chiller’s evaporator. Once the water in the air handler system is used, it becomes warm and is sent back to the chiller. A chiller has four main parts: an evaporator, compressor, condenser, and expansion valve.Īn air-cooled chiller works by absorbing the heat from processed water. York® air-cooled chillers generally come in sizes from 15 ton to 500 ton capacities.An industrial air-cooled chiller is a refrigeration system that cools fluids and works in tandem with a facility's air handler system. They operate as variable speed screw or scroll type chillers. The variable screw type compressor is more common and seems to be gaining in new installations each year. Variable speed screw chillers are offered from 150 ton to 500 ton capacities.Īir-cooled York chiller repair and service begins with diagnosis and listening to the people that use the chiller daily or with greater frequencies. Listening to our customer about specific behavior patterns, helps us to better understand the best course for repairing your air-cooled York® chiller. When it comes to scroll chillers from York®, the models offered today include the YCAL and YLAA Scroll Chillers. These range in sizes from 15 ton to 230 ton, with the YLAA models including variable-speed drive fans. Many of the York® air-cooled chillers that are in service today are in their YVAA variable speed drive screw chiller series. These are of a patented, liquid cooled variety and customized to specific job requirements. These, as with all York chillers do require maintenance for optimal performance and reliability. Give us a call to learn more about the maintenance for your particular model and tonnage. Included in the variable speed screw chiller line up is the YVFA Free Cooling and the YCIV models. These range from 150 ton to 500 ton capacities. More about these specific models is included below as a general quick reference. Our goal is to provide you as our customer a complete understanding of how-to best repair or service your York® air-cooled chiller. Our factory trained and certified installers and servicers will get you back up and running as soon as possible with the least amount of cost. York® water-cooled chillers generally come in sizes from 125 ton to 5,500 ton capacities. They operate as variable speed screw, scroll and centrifugal types. Refrigerant options come in R-410A, R-513A or R-134a. Water-cooled York chiller repair and service begins with diagnosis and listening to the people that use the chiller daily or with greater frequencies. Listening to our customer about what the 'behavior' patterns have been for the chiller helps us to better understand the best course for repairing your chiller. We work hard to restore factory performance with the least amount of costs involved. York® water-cooled chillers that are in service today are designed for either replacement or new commercial construction applications depending on the needs and requirements. These plants include the YMC, YZ, YK, YVWA, YCWL, YK-EP, YST, Titan™ OM and the CYK series of water-cooled chillers. More about each one of these models is included below.Īgain, when you are choosing who you want to come and repair or service your chiller, trust factory certified professionals to do the job right the first time. Our main goal is to provide you as our customer a complete understanding of how-to best repair or service your York® water-cooled chiller.
