If there is insufficient flow and pressure, then there will not be enough cooling and the building may get hot during periods of high cooling load. The condenser water pump must be sized properly to circulate the correct amount of flow at the correct pressure in order to achieve proper cooling within the building. The cooling tower then cools the condenser water, and the condenser water is supplied back to the chiller. The condenser water pump circulates return condenser water from the chiller back to the cooling tower. The condenser water pump is used to circulate condenser water either in an open or a closed circuit system. The condenser water pump is a part of an overall condenser water system that often includes a chiller, piping, valves/fittings, water treatment, and a cooling tower. This guide covers the design and selection of a condenser water pump. Section 3.0: Overall Condenser Water System However, an SI version will also be provided in the future. As such, this guide focuses exclusively on the USCS. The primary units that are used in the calculator are United States Customary System Units (USCS). Lastly, each individual item within the Condenser Water Pump Schedule will be discussed in order to give you more knowledge on how to complete the schedule for your specific condenser water pump application. The primary purpose of the calculator is to find the total dynamic head and net positive suction head available for use in the Condenser Water Pump Schedule. Following the overall condenser water system, the inputs, outputs and references used in the calculator will be covered. The overall condenser water system will help you to visualize how the condenser water pump fits within the overall system and will also help you to determine the hydraulically remote run for pressure drop calculations. This guide covers the overall condenser water system, the calculator and the condenser water pump schedule. The purpose of this guide is to provide the necessary background information on the Condenser Water Pump calculator to be able to use the calculator and to fill out a condenser water pump schedule.
