Programs Offered

The Programs currently available include what we considered the "basic package" necessary in any design engineering office (to provide the maximum usefulness, benefit and time savings). It is ESI's intent to continually expand the program offerings, ultimately providing every calculation one would need in the design of an HVAC system.

The current program offering includes:
  • Psychrometric Properties
  • Psychrometric Processes
    • Mixing
    • Cooling and Dehumidifying
    • Sensible Heating or Cooling
    • Isothermal Humidification
    • Evaporative Cooling
    • Difference Between Two State Points
  • Heating and Cooling Load Calculations
  • Heating and Cooling Coil Selection
  • Heating and Cooling Coil Diagnostics
  • Expansion Tank Sizing
  • Hydronic Pipe Sizing
  • Steam Properties
  • Steam Processes
    • Expansion (Power) Process
    • Fuel Heat Required to Generate Steam
    • Steam Control Valve Sizing
    • Steam Orifice Size or Capacity
    • Difference Between 2 State Points

The Programs will be modified, expanded and updated depending upon technological advances, user comments, and our objective of providing all the calculations necessary for the design of energy efficient HVAC systems.

Programs in development include:
  • Pipe sizing calculations for
    • Open Water Systems (Condenser Water)
    • Gas Piping
    • Fuel Oil Piping
    • Refrigerant Piping
