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%.
In the northern, the temperature of soil is very low and the heating load is dominant. If the peak load of heating was supplied by ground exchanger, the ground-coulped heat pump heating efficiency is low. Therefore the solar energy can be utilized as assisted source. This article 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 pumps by using the solar energy as an assisted source system in BOGART factory. The resoults show that the program is more economical.
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.
