The Mechanics Institute’s New Student Registration will reopen in June 2022 for the Fall 2022 Semester. Please email email@example.com for more information.
The HVAC/R Systems Design program is a two-year discipline designed to provide students with a practical understanding of heating, ventilation, and air conditioning concepts as they apply to the field of construction. Classes are taught Monday and Wednesday evenings from 5:30 pm-8:30 pm.
Sample HVAC/R Systems Design Two-Year Curriculum
First Year – Fall Semester
Fundamentals of HVAC/R
The educational objective of this course is to provide the student with an introduction and a broad overview of the heating, ventilation, air conditioning, and refrigeration industry along with its history. Students will be provided with basic theory, and specific examples to better understand the wide range of systems in use and how they have evolved as well as the direction the industry is going.
Hydronic Heating Systems
Hydronics can be defined as a science that utilizes water or steam to transfer heat from the source where it is produced to an area where it can be used through a closed system of piping. Students will gain a working knowledge of boilers and terminal units used for hydronic heating systems, such as baseboard heaters, convectors, fan coil units, reheat coils and “radiators.” Different types of systems and materials used for heating applications will be discussed along with codes and standards that apply.
First Year – Spring Semester
Water Chillers and Cooling Towers The removal of heat from conditioned spaces and equipment can be accomplished by different methods, but cooling towers, chillers, heat exchangers and pumps provide a means of providing water for removing heat effectively. Students will learn the difference between different types of cooling towers and chillers as well as common terms associated with water-based systems including economizer operation and concerns associated with their operation.
Heat Load Calculations and Energy Codes
The educational objective of this course is to provide an understanding of the basic concepts associated with estimating the heat loss and load used to size equipment for heating and cooling applications. Basic theory will be introduced as it is needed to calculate the rate of heat transfer and temperature changes accurately. Instructional topics include fundamentals of thermodynamics, heat capacity, heat transfer, heat loss and heat gain along with allowances for ventilation, and infiltration.
Second Year – Fall Semester
This course will focus on the treatment and distribution of air associated with HVAC equipment. It will introduce the psychrometric chart as a “road map” and ASHRAE standards for energy, indoor air quality and human comfort and how they apply in the design and selection of air handling systems. It will also include the ductwork distribution and fans used to supply, return, exhaust and introduce outdoor air into a conditioned space as well as related topics.
Psychrometrics and Humidification
The educational objective of this course is to introduce the student to the properties of moist air and the gas laws as they apply to the HVAC industry. The use of the Psychrometric chart in diagramming the conditions of air as it changes in pressure, volume, temperature, moisture, and total energy is the central aspect of this class and students will be given a better understanding of how humidity affects comfort. Total, sensible and latent heat relationships are explained along with wet bulb temperature.
Second Year – Spring Semester
Control Systems and Electric Power Supply
The educational objective of this course is to provide the student with an introduction to the electrical concepts associated with the power requirements for HVAC/R equipment including electric motors and their control. Some basic HVAC control systems including pneumatic and electronic as well as direct digital controls and their applications within buildings will be studied.
HVAC/R Practicum and Estimating
This class intends to give the student the ability to take what they have gained from the program and develop an individual or group term project to pull together ideas as may apply to their interests. Site visits to observe the installation and operation of HVAC&R systems are intended. Also, an estimating approach to the industry will be provided including methods of organizing data.
