Economic Analysis Of East China Source Heat Pump Operating

Energy is the material basis of human survival and development. With the advancement and development of human civilization, human consumption of energy more and more, failure to take measures to lead to serious consequences of energy depletion, and environmental degradation. Therefore, to develop renewable energy sources has become a major task in the 21 st century economy and building a moderately prosperous society without delay. Heat pump technology is one of the key technology of low-energy renewable.Ground source heat pump system with energy-effective, environmentally friendly, high efficiency, high energy and the rational use of shallow geothermal renewable energy and other advantages, it will overcome the HVAC and hot water supply by way of energy, high energy consumption and environmental pollution problems. Therefore, in order to better promote the application of technology, the paper will be ground source heat pump system(Option One) as the center of the air-cooled heat pump system(Option Two) + gas boiler and chiller(Option Three) in energy consumption and thermal economy comparison, analysis of their strengths and weaknesses.This paper analyzes the formation of ground source heat pump, elaborated on how it works and classification. Establish energy analysis model, using BIN method for ground source heat pump system heating season, cooling season perform energy analysis calculated and compared with the annual energy consumption of two other programs. Thermal analysis using economics, through three programs to establish economic model to analyze the cost of each option Cooling,heating costs, as well as factors affecting the exergy efficiency of heating costs.Although the initial investment cost of ground source heat pump system is high, get cost savings through energy analysis in the latter part of the operating costs are very obvious. In the class system, the ground source heat pump in the cooling season, or whether it is in the running costs of heating season is the lowest. In the cooling season, the unit cost of the cold ground source heat pump is almost half of the operating costs of air-cooled heat pump units, two-thirds of the chiller operating costs.Analysis showed that exergy efficiency of the three programs is relatively low, especially in the cooling season. But no matter what the season is, exergy efficiency of ground source heat pump system is relatively highest. In the heating operation, there is the cost of natural gas and electricity to run as an energy balance, balance of 3. When thermoelectric parity is less than 3, the use of natural gas heating is more economical than using electricity; when the thermoelectric parity than 3, the use of energy more economical than using natural gas. Thermoelectric parity project area 4.66. Therefore, the use of ground source heat pump system energy savings more heating.
