Description

CTI ATC 105:2022 outlines the procedures and instrumentation required for testing and evaluating the thermal performance of water-cooling towers. It focuses on determining a tower's ability to cool water under specific conditions and provides guidance on instrumentation, testing methods, and data analysis.

The code applies to various cooling tower types and aims to ensure consistent and reliable performance evaluation.

Scope

CTI ATC-105:2022 covers the determination of the thermal capability of water-cooling towers. This includes: 

1. Instrumentation: Specifies the necessary instruments and equipment for measuring water flow rate, temperatures (hot and cold water), air conditions (wet-bulb temperature), and fan power. 

2. Testing Procedures: Outlines the procedures for conducting acceptance tests on cooling towers, including test duration, data recording, and data analysis. 

3. Data Analysis: Provides guidance on how to analyze test results to determine the cooling tower's thermal performance and compare it to manufacturer specifications or performance curves. 

4. Applicability: The code is applicable to various types of cooling towers, including mechanical-draft and natural-draft towers, and may be used for both new and existing installations. 

5. Contractual Testing: Emphasizes that acceptance tests should be performed by a CTI-licensed test agent in the presence of the owner and manufacturer. 

6. Preparation: Requires that cooling towers be prepared for testing in accordance with CTI PGT-156, which outlines specific preparation requirements for thermal performance tests. 

7. Safety: Emphasizes the importance of safe access to measurement points and adherence to relevant safety regulations during testing. 

The code aims to provide a standardized and reliable method for evaluating the thermal performance of cooling towers, ensuring that they meet specified performance criteria and operate efficiently.
