HVAC Design Fundamentals 1

Description

HVAC Design Fundamentals 1

PDH Credit: 6.0 hours
CEU Credit: 0.6 hours

Topics Covered:

• HVAC Design Fundamentals
  • Thermodynamic Refrigeration Cycles
    • The second law of thermodynamics states that heat cannot spontaneously flow from a cold system to a hotter system without the input of work. For example, an air conditioning system requires work input (typically in the form of mechanical compression) to cool a space – moving the heat from a space (the heat source) to a warmer location (the heat sink). Sadi Carnot first described the principle of a refrigeration cycle as a heat engine.
  • Fluid Flow
  • Thermal Comfort
  • Indoor Environment
• Heat Transfer
  • Heat transfer is the exchange of thermal energy between physical systems governed by the First Law of Thermodynamics. The direction of heat transfer is from a region of high temperature to a region of lower temperature, and is governed by the Second Law of Thermodynamics.
  • The three fundamental modes of heat transfer are:
    • Conduction
      • Steady-State Conduction
      • Unsteady-State Conduction
    • Convection
    • Radiation
  • Heat Transfer Through Walls
  • Heat Transfer Through Roofs
  • Heat Transfer Through Glass
  • Heat Transfer Through Floors and Interior Partitions
• Psychrometrics
  • Psychrometrics is the field of study concerned with the determination of physical and thermodynamic properties of gas-vapor mixtures. The term derives from the Greek psuchron meaning “cold” and metron meaning “means of measurement”
  • Wet-Bulb and Dew Point Temperatures
  • Cooling and Dehumidification
  • Heating and Humidification
  • The Psychrometric Chart and The Air Conditioning Process
