- Abstract
This paper introduces the theoretical basis and application method for heat transfer model of buried tube (pipe in pipe and U- type) heat exchanger for ground source heat pump, and a practical example is calculated. Then, the calculation results are analyzed and discussed. In particular, the correlation coefficient and calculation method of tube group exchanger is discussed; the method for determining known parameter and some basic data for main procedure GSHP.HTM is analyzed. The calculation formula and data sampling for JSW.HTM subroutine is introduced. At last, the problems in application of calculation procedure, to which should pay attention, are discussed.
