Winter part of the construction area using ground source heat pump heating, the rest of the construction area of ??central heating for the summer using ground source heat pump and cooling system, practical, effective solution to the cold regions using ground source heat pump soil exist "cold stack".

In winter a gross floor area of the soil source heat pumps for hot, with a focus on the rest of floor space for the hot, summer soil source heat pump system for cold, practical, effective use of soil cold soil source heat pump is the "COLD" pile.

A winter part of floor space heats with the soil source heat pump, other part of floor space heats with the centralism, summer uses the soil source heat pump system to supply coldly, actual, effectively to solve the cold area use soil source heat pump soil existence “the cold stack” the question.

Soil source heat pump heating system in winter part of the area, rest area with central heating, using ground source heat pump system for cooling in the summer, practical, effective solution to cold region using ground-source heat pump of soil "accumulation of cold".
