▀█▄▄ Earth Coupled Analysis (ECA) quickly calculates the ▀▀▄▄██▀▀
▄▄▀▀██▄▄ required pipe loop length necessary for heating and ▄█▀▀
▄██ ▀██ cooling a building with a given heat pump, soil, and █▓ █████▀
▓██▄ ▄▀ weather conditions. ECA can analyze both vertical and █▓ █▀████▄
▀▀████▄▄ horizontal pipe systems. In addition to computing pipe ▀▄ ▄███▓▀
▄▀ ▀███▓▄ lengths, ECA can also generate a complete bill of ▄▄████▀▀
█▓ █▄████▀ materials with a cost estimate of the required labor ▓██▀ ▀▄
█▓ █████▄ and materials. Pressure losses through the equipment ▀██ ▄██
▀█▄▄ room, heat pump, header pipe, and the earth coil are ▀▀▄▄██▀▀
▄▄▀▀██▄▄ computed along with the purge pressure and flow ▄█▀▀
▄██ ▀██ requirements. Heating and cooling runtime fractions █▓ █████▀
▓██▄ ▄▀ are computed on a temperature bin basis. ECA is █▓ █▀████▄
▀▀████▄▄ supplied with built-in data on many pipe types ▀▄ ▄███▓▀
▄▀ ▀███▓▄ including polyethylene, polybutylene, copper, iron, ▄▄████▀▀
█▓ █▄████▀ and others. However, data on all pipe types can be ▓██▀ ▀▄
█▓ █████▄ revised and additional pipe types can be defined as ▀██ ▄██
▀█▄▄ well. Equivalent length data for fittings on all pipe ▀▀▄▄██▀▀
▄▄▀▀██▄▄ types is also included. ECA comes with a heat pump ▄█▀▀
▄██ ▀██ data file containing performance data on models from █▓ █████▀
▓██▄ ▄▀ several manufacturers. There is also provision for the █▓ █▀████▄
▀▀████▄▄ user to add heat pump data from any other ▀▄ ▄███▓▀
▄▀ ▀███▓▄ manufacturer. Data on all soil types listed in the ▄▄████▀▀
█▓ █▄████▀ ASHRAE manual are built-in to ECA, and the user can ▓██▀ ▀▄
█▓ █████▄ add more. Weather data for over 200 cities are ▀██ ▄██
▀█▄▄ built-in, and the weather data can be revised or added ▀▀▄▄██▀▀
▄▄▀▀██▄▄ to as much as desired. ▄█▀▀
▄██ ▀██ Calculation Method █▓ █████▀
▓██▄ ▄▀ █▓ █▀████▄
▀▀████▄▄ The ECA Program follows the methodology described in ▀▄ ▄███▓▀
▄▀ ▀███▓▄ the Design/Data Manual for Closed-Loop Ground-Coupled ▄▄████▀▀
█▓ █▄████▀ Heat Pump Systems published by the American Society of ▓██▀ ▀▄
█▓ █████▄ Heating, Refrigerating,and Air Conditioning Engineers ▀██ ▄██
▀█▄▄ (ASHRAE). All results computed by the program can be ▀▀▄▄██▀▀
▄▄▀▀██▄▄ easily verified by hand to be in accordance with ▄█▀▀
▄██ ▀██ ASHRAE. █▓ █████▀
▓██▄ ▄▀ █▓ █▀████▄
▀▀████▄▄ Program Input ▀▄ ▄███▓▀
▄▀ ▀███▓▄ The ECA program s a true Windows program complete with ▄▄████▀▀
█▓ █▄████▀ toolbars and hyperlinked help. All input data is ▓██▀ ▀▄
█▓ █████▄ checked at the time of entry so that no improper data ▀██ ▄██
▀█▄▄ can be entered. Two types of data are requested: ▀▀▄▄██▀▀
