在叙述3种类型的地铁环控系统和屏蔽门系统在国内外应用现状的基础上，分析了屏蔽门系统的节能原理，并针对国内屏蔽门系统应用存在的误区，提出在北方地区应对传统对屏蔽门系统进行节能改造和创新，推荐多功能屏蔽门和带风口屏蔽门，建议通过实现屏蔽门系统国产化等措施，使屏蔽门系统在国内得到更广泛的应用。
Made a comparison of the geothermal pump type air conditioning system with the conventional system on the total initial investment,operation cost and Eco-efficiency combined with the construction examples of the air conditioning and refrigerating heating water geothermal pump system of one hotel in Shaoshan.It expounds that the geothermal pump system is an environmental protection and energy conservation technology employed in green hotel.
Presents the practicability of applying artificial neural network to forecast performance of ground-source heat pump units.Establishes the forecasting model and simulates and forecasts the operating performance of a unit.The deviation coefficient between the simulating value and experimental value is less than 2.63%.
The author has tested two different heating periods(called initial cold period and final cold period) performance parameters of the soil source heat pump unit in one office building in Beijing,based on which the writer has analyzed the operative performance of the unit.From the test results,it can be gained that the coefficient of performance(COP) of the heat pump unit and the system energy efficient ratio(EER) changes much in different heating periods;It is clear that the outlet water temperature of burying pipe decline 2.96℃ after the whole winter season,although water quantity of flow in the burying pipe is almost the same and variation between inlet and outlet water temperature can be negligible.The paper gives reasons for the above station and suggestions to optimize the design of the soil source heat pump.Then it proves energy saving of this system by comparing with air source heat pump and heating boiler.
This article gives a brief introduction to the definition and developing trend of the green hotel and the rationale of the geothermal pump type air conditioning system, makes a comparison of it with the conventional system on the total initial investment、operation cost and Eco-efficiency combined with the construction examples of the air conditioning and refrigerating heating water geothermal pump system of one hotel in Shaoshan. It expounds that the geothermal pump system is an environmental protection and energy conservation technology employed in green hotel.
