Cooling tower lab manual

operating the cooling tower, set the air orifice pressure according to the manometer. Pressure transducer readings will be recorded from the VI once the system has reached steady state and will be compared to the manometer reading. the cooling tower inlet piping (4" supply line) and the cooling tower outlet piping (8" return line) so that all external piping can be emptied during a system shutdown period. See drawing below for further details. In a multiple cooling tower system, there . Laboratory-scale cooling tower replicates the function of an industries process cooling tower for study and experiment purposes. The electric flower of cooling tower in the laboratory can be controlled. This is used to study the amount of heat transfer Estimated Reading Time: 13 mins.

BASICS OF TOWER OPERATION Cooling Towers are heat transfer devices that are designed to remove heat from the hot water which returns from an HVAC heat source such as a chiller, or from an Industrial Process such as a condenser or heat exchanger, and transfers this heat to the atmosphere. In the case of The Cooling Tower Company (TCTC) cooling. Pre-lab Homework for Cooling Tower Experiment (to be completed individually) 1. Using a psychrometric chart determine the enthalpy of humid air at a dry-bulb temperature of 75 F and a wet-bulb temperature of 60 F. 2. At the air conditions described in problem #1, determine the air mass velocity of. cooling tower. 5 To study various components in room air conditioner. 6 To find performance of a refrigeration test rig system by using different expansion devices. 7 To study different control devices of a refrigeration system. 8 To study various compressor. 9 To find the performance parameters of Ice Plant.

The thermal capability of a cooling tower used for air condition- ing is often expressed in nominal cooling tower tons. A nominal cooling tower ton is defined as cooling 3 gpm of water from 95°F to 85°F at a 78°F entering air wet-bulb temperature. At these condi- tions, the cooling tower rejects 15, Btuih per nominal cooling tower ton. Marley NC Steel Cooling Tower User Manual. Library, Manuals. Installation, operation and maintenance instructions - as well as those offered separately on motors, fans, float valves, etc. - are intended to assure that your NC tower serves you properly for the maximum possible time. Fig Condition in cooling tower: (a), (b) at bottom of tower, (c) at the of tower Heat transfer from the water to the interface is used to warm the air as well as to provide heat of vaporization, although the water cooling due to evaporation is much greater than that from sensible-heat transfer to the air.
