Abstract

See full text

A computer which functions by a performance prediction program for a ground source heat pump system of the present invention and a performance prediction system constructed thereby include a dimensionless distance calculating means, a first dimensionless time calculating means, a second dimensionless time calculating means, a boundary time acquiring means, an underground temperature change calculating means, and a tube surface temperature change calculating means. The performance prediction program and performance prediction system can be applied to the design of heat exchange system by obtaining predicted underground temperature data for the ground source heat pump system with high accuracy and predicting the performance for the ground source heat pump system based on the resulting underground temperature changes, etc., in view of the use of a plurality of buried tubes, underground temperature change patterns for buried tubes placed at different intervals, and the use of U-shaped tube heat exchangers.
