I am excited to share my journey and experiences with you as a proud member of the AHI Carrier family. My time here has been marked by growth, innovation, and a dedication to excellence. I am thrilled to highlight some of the key moments and achievements in my career with this esteemed organization.
I joined AHI Carrier as back-office support for Sales Engineers in the Johannesburg, Durban, and Cape Town branches in 2020. Initially, my responsibility was to select equipment for all airside projects and prepare quotations that met clients’ requirements and budgets. Occasionally, I would also attend meetings with Sales Engineers or the Toshiba Specifying Engineer to understand clients’ needs and offer the most suitable products. After completing various design courses with Carrier University in 2021, I was entrusted with Carrier’s eDesign Suite programs in the Southern Africa region. I am responsible for licensing, distributing the programs, and providing training and technical support to customers. Currently, I support over 300 consulting and contracting firms in our territory.
In January 2024, I assisted a client with designing rooftop units for a project in Zambia. The project required the highest degree of indoor comfort and humidity control. To meet these stringent requirements, we incorporated an additional condensation coil to reheat the air after the evaporator. The recovered hot gas is injected into this coil to reheat the air after dehumidification. This coil allows for controlling maximum humidity levels efficiently, regardless of location and part-load of the units. Since we could not offer humidifiers with our units, we integrated third-party humidifiers. EC type plug fans with airflow sensors and variable speed were used for evaporators and condensers to reduce power consumption. The nine 50FC rooftop units will be ready for delivery soon. This project is a notable success for the company as these are the first rooftop units that AHI Carrier South Africa will be exporting to the continent.
In my experience, the most remarkable product that AHI Carrier has introduced to our market is the Carrier’s Hourly Analysis Program, commonly known as HAP. HAP is the flagship of Carrier’s eDesign Suite programs, made for consulting engineers, design and build contractors, HVAC contractors, facility engineers, and other professionals involved in the design and analysis of building HVAC systems. HAP calculates design loads for sizing HVAC systems and components. It provides information such as cooling and heating loads, required airflow rates, circulation fan sizes, chillers, boilers, and condensing units needed for selecting and specifying equipment. The program also calculates annual energy use and costs for HVAC and non-HVAC systems in a building by simulating operation for all 8,760 hours in a year. Results from the energy analysis help compare the energy use and costs of alternate HVAC system designs to choose the best option for the project. Developed in the USA, HAP is used extensively globally, with calculations based on ASHRAE fundamentals but adaptable to match various country standards.
I believe that Carrier’s eDesign Suite programs make AHI Carrier uniquely positioned in the market. eDesign Suite refers to a group of software programs that automate several key HVAC engineering tasks. While AHI Carrier charges a licensing fee for these programs, the objective is to provide customers with accurate, versatile tools to conduct their business more productively. By providing these tools and assisting customers in their use, AHI Carrier Sales Engineers can build and strengthen relationships with customers, leading to more favorable design bases, equipment specifications, and equipment sales.
I am deeply grateful for the opportunities I have had to grow and thrive within the AHI Carrier family. My journey here has been nothing short of remarkable, and I am excited to continue contributing to our shared success in the years to come.
Thank you for allowing me to share my story with you.
