Heat Load Calculations are the basics of HVAC design, determining the amount of heating or cooling required to maintain a comfortable indoor environment. By assessing various factors such as external and internal heat gains, occupancy, lighting, and climate conditions, engineers can accurately size and design HVAC systems. Real-world samples and case studies are integrated into the curriculum, allowing students to apply theoretical knowledge to practical scenarios. This hands-on approach ensures that learners not only understand the principles but can also adeptly navigate the complexities of heat load assessments. Psychrometry is the science of studying the thermodynamic properties of air and vapor mixtures, a fundamental aspect of HVAC design. Understanding psychrometric properties and processes is crucial for analyzing and deploying air conditions to achieve desired comfort levels. This module introduces learners to psychrometric charts, aiding in visualizing the relationships between temperature, humidity, and other air properties. Practical applications of psychrometry in HVAC systems, such as the design of air conditioning and refrigeration processes, are explored. The integration of Heat Load Calculations and Psychrometry is a specialty of this module. Students learn to control psychrometric data in heat load assessments, ensuring that HVAC systems not only meet thermal comfort requirements but also operate with optimal efficiency. The synergy between these concepts enables engineers to design systems that consider both sensible and latent heat, providing a complete approach to indoor climate control. Upon completion of this module, students gain industry-relevant skills to accurately estimate and manage heat loads in diverse settings. Whether designing systems for residential spaces, commercial buildings, or industrial complexes, the knowledge acquired in this module empowers learners to create HVAC solutions that are both effective and energy-efficient. In essence, this module serves as a comprehensive guide, arming learners with the knowledge and skills necessary to navigate the intricate world of Heat Load Calculations and Psychrometry, essential pillars in the design and optimization of HVAC systems.

Students can aware of the impact of various internal and external parameters that plays vital role in total heat gain for given space. The design of heating, ventilation, and air conditioning systems, as well as energy estimation for buildings are influenced by outdoor design circumstances as they directly influence the transmission heat gain of a structure. Student will learn to calculate total heat gain for given space using various tables provided in ISHRAE Standard and Carrier Handbook. ISHRAE stand for Indian Society of Heating, Refrigerating and Air Conditioning Engineers. With the help of ISHRAE students can set design condition for indoor/outdoor, select ventilation air standard & heat load standard for area and occupancy. Students can understand basic concept of psychrometric, significance of various air properties, various psychrometric processes and its implementation based on application. Basic concept of psychrometric and psychrometric processes are used to control the temperature, relative humidity, and quality of the room air which basic requirement of any HVAC system. Students will have practice on sample heat load calculation in this module. The importance of accurate load calculations for air conditioning design can never be overemphasised as it affects the selection of equipment. The calculations are performed for peak summer design conditions which normally will contribute to more heat gain into the space than monsoon. In this module students will get an opportunity to learn HVAC total load calculation based on L & T experience on very large project. This will help to calculate total heat load in building
