Engineering Software International

Engineering Software International, Inc. was founded to enable engineering designers to perform the calculations required in their daily activities in considerably less time (thereby significantly enhancing their productivity).

Building systems technology has reached a new level of maturity that will require considerably more engineering sophistication. The driving force is the requirement for improved energy efficiency, compatible with the long-range objective of sustainability (while providing improved performance).

Programs Offered

The Programs currently available include what we considered the "basic package" necessary in any design engineering office (to provide the maximum usefulness, maximum benefit and greatest 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 HVAC systems.
