GSHP analysis

 1 problem facing the development of concepts : air source heat pump and gas. Coal-fired heating technology is relatively mature, people choose ground source heat pump system will face resistance.

 2, HVAC technology, and other technical support : HVAC technology is the ground source heat pump technology and drilling technology combines the technologies, both are indispensable. This requires organizers of the project coordination and engineering and technical personnel can reasonably make full technical and economic analysis.

3, the impact on the environment : groundwater recharge imperfect to a certain extent influence the heat to low water-source heat pumps for further promotion; In addition to the drilling ground source heat pump air-conditioning systems soil heat, humidity and salt needs further study the impact of migration. how to minimize the negative factors must be taken into account.

4, the initial investment is not all : the ground-source heat pump systems are economically rational. As the drilling of the initial investment costs may account for more than 50% of the entire system. Some investors may return to the traditional form of air conditioning.

 5 : ground source heat pump system installation and maintenance costs for the installation of higher electricity and refrigeration. /ton million compared to the controlling of natural gas heating system. /ton ground source heat pump 600 ～ 1000 yuan (1ton= 1.01605t) is high. The payback period is 5 to 8 years; ground source heat pump system and the maintenance more difficult. This to a certain extent influence the use of it.

 6, the characteristics of soil properties : soil varies with the changes in place. In one of the results of the study may not apply to another area entirely, or even re-examining the need for consequential amendments.
