Residential Software - CLGS

CLGS is a menu driven, user friendly closed-loop ground source heat exchanger design program. It rapidly designs everything from the smallest to multi-ton residential applications. CLGS also provides energy efficiency comparisons. The user:

• Supplies the buildings heating and cooling loads
  
• Selects a design area from a menu of locations
  
• Chooses the heat exchanger design configuration, vertical or horizontal, pipe size and type
  
• Enters heat pump capacities

The program uses preprogrammed or user-input weather and other data, and then sizes the vertical or horizontal heat exchanger.

CLGS output screens provide:

• Estimated annual cooling, space heating and domestic hot water heating costs
  
• Loop pipe sizes and pressure drops, also purging pump size necessary to flush and purge air and debris
  
• Comparison operating costs of gas, propane, high efficiency electric heating & cooling, and geothermal systems

While CLGS is primarily oriented to residential applications, it can also be used for small commercial applications that are not multiple zone sensitive.
