Course Summary

• Performance analysing  – based on Climacheck method, Training Level 1

Cooling and Heating systems consume 15-20% of the electricity produced globally. To maintain temperature is critical but maintaining temperatures alone are no longer sufficient. Knowing the performance of these systems is therefore critical in order to make them efficient. With increasing energy demand and focus on global warming, the built environment is facing increased scrutiny. In many countries, and more so in the tropics, HVACR equipment in buildings are a major source of energy consumption which typically have high maintenance costs associated with them. There is also an increased focus on Measuring and Verification (M&V), as well as early warning to achieve maximum reliability to reduce loss of perishable goods, production capacity and to avoid bad will with tenants and guests due to failing temperatures.

Training starts with a review of the basic thermodynamics required to establish performance factors (a pretraining refresher will be distributed for participants that want to make sure they are up to speed with definitions and basics used for analysing). Then training moves into data collection, including what sensors are required and how they should be applied to minimize uncertainty of results. How to validate data inputs and results are covered.

Course Objective

Master Class Course Goals:

1. To give participants a method to compare operation of a system with design, maintenance instructions and good practice.
2. To make participants aware of the possibility to reduce failure rates, maintenance cost, energy consumption and refrigerant leaks by introducing state of the art M&V methods.

Session 1:

• Introduction to principles of Thermodynamics and how they relate to vapour compression systems
• Pressure enthalpy charts and Energy Efficiency

 Session 2:

• How to set-up measuring systems with temperature, pressure and power meters and use a spreadsheet based analysing tool to analyze an HVACR process
• KPIs of a refrigeration / air-conditioning process, and how to improve a basic refrigeration / air-conditioning process

Course Outcome

• Identify what data points that is required to analyze basic HVACR equipment.
• Apply sensors on correct position and with correct application to get good quality data.
• Use data collection units to collect pressures, temperatures and electrical measurements.
• Adjust/configure ranges for basic sensors used.
• Validate data inputs
• Select and make basic adaptation of appropriate analyzing “template” to correspond to measured system
• Validate results such as versus design and/or good practice.
• Understand and be able to compare performance indicators such as COP, System Efficiency Index, compressor/evaporators/condensers efficiency.
• Understand interaction of different adjustment parameters in an HVACR system
• Awareness of the importance of commissioning of controls for each installation

Target Audience

This training is aimed for trained technicians and mechanical/electrical engineers with practical on-field experience with chillers, air conditioning, refrigeration and heat pump systems. ESCOs, site engineers, operation engineers/managers/technicians, energy engineers and cooling equipment maintenance and servicing personnel.
