Hot pump ground buries tubal heat exchanger to conduct heat to the model reviews
From;    Author:Stand originally

The ground buries source tubal the ground to heat up pump technology is the forward position with air conditioning at present medium domain study one of tasks. The ground buries source tubal the ground because hot pump system has function coefficient tall, energy-saving effect is good, use but effect of second birth the sources of energy, environmental protection good, system is simple wait for an advantage, be in Euramerican applying relatively extensive, but still be in in our country start level, only at present very few ground buries source tubal the ground to heat up pump aircrew to move successfully. Our country region is vast, contain is worn rich upper shallow-layer (be less than 400 m normally) resource of the heat of the earth's interior, because this uses resource of shallow-layer terrestrial heat effectively, in order to overcome the confine in technology of the traditional air conditioning that heat up pump and inadequacy, it is very significant with what have economic value. Bury source tubal the ground at present to heat up pump to do not have hot like air source pump to develop quickly in that way, bury source tubal the ground to heat up pump besides the ground invest to be mixed high first outside the requirement of pair of cliff land system, also do not eliminate to still lack reliable systematic design and simulation tool up to now. The canal that e of C a n and s of a of g of F o r think through computation the ground of current North America buries source tubal the ground to heat up the ground in pump project example to bury tubal heat exchanger is long bigger than slanting actually 10% ~ 30%[1] , make thereby short-term inside reclaim capital is more impossible, go against the ground to bury source tubal the ground to heat up the development of pump and promotion.

The ground buries a canal between heat exchanger and cliff land system conduct heat of dispute stable state, inside infinity area conduct heat, the process is very complex, influencing factor is various. From the point of existing document, about subterranean heat exchanger pass hot mechanism to analyse main concentration to studying theoretically and try applied phase, the research of field of temperature of cliff land system is based on heat to conduct a principle, conduct heat to considering what groundwater moves the research such as mechanism and heat exchange mechanism is very few, and domestic and international document shows groundwater is transverse seep conducts heat to cliff land system the process has huge to affect [25] . Accordingly, after to understand a setting the ground buries tubal heat exchanger, be opposite the influence of character of original underground environment, be conducted to heat and groundwater carries the land that uses joint action to fall buries tubal heat exchanger to pass hot mechanism to undertake study very necessary.

1 ground buries those who be in charge of heat exchanger to conduct heat model

The factor that affects the ground to bury source tubal the ground to heat up pump system performance is more, the possibility that happens to change all round the property that includes material of groundwater flow, backfill, heat exchanger and the change along sex of other people of system of Guan Changyan land are waited a moment, how to perfect the ground to bury those who be in charge of heat exchanger to conduct heat model, make its better the circumstance of real heat exchange that imitate ground buries tubal heat exchanger, the dimension that buries tubal heat exchanger optimally certainly is the key that development and promotion ground bury source tubal the ground to heat up pump.
