Abstract: Based on the design of the building load calculations, thermal response of soil test wells, ground heat exchanger layout and the construction methods of technical analysis, consider that ground source heat pump ground heat exchanger costs are falling space.

Key words: ground source heat pump heat exchanger cost analysis

1. Overview With China Energy Reduction Implementation of the strategy development, research and utilization of new energy saving air-conditioning has become an important issue in society today, as ground source heat pump has a high coefficient of cooling performance, energy saving, the use of renewable Energy , Environmental effect, the system is simple and easy to maintain, have been widely used in Europe and the United States across the country to promote the government's active support, the ground source heat pump is also in the construction sector has been growing rapidly. But the cost of ground source heat pump air conditioning than the traditional expensive, Er Shi owners daunting, restricted the promotion of use of ground source heat pump, therefore, reduce the cost of ground source heat pump to reduce its one-time investment, on the ground source heat pump in the development of air conditioning of great significance. This article focuses on ground source heat pump heat exchanger cost analysis of the factors affecting the technology for engineering applications.

Ground Source Heat Pump System (ground source) of the initial investment may seem high compared to traditional systems, so that consumers (developers) will worry about whether the technology works using the price rise, affecting some consumers recognized for the technology. But the ground source heat pump system eliminates the transport process of energy transmission infrastructure investment, and that the system could also cooling (heating) and for the new air (and water for life), overall cost savings will be significant price advantage, however, and not a full understanding by consumers. 1000 square meters of office buildings in the use of ground source heat pump, the winter run 24 hours at room temperature maintained at 22 ? 24 , the power consumption of only 140 day to 150 degrees. If the initial investment, running costs, maintenance costs, useful life, land use, infrastructure construction, energy use and other conditions into account, the daily load unit costs are lower than other types of air conditioning.

Ground source heat pump prices in three parts, the end part of the interior, engine room parts, outdoor buried part of the main cost of ground source heat pump ground heat exchanger in your outdoor, ground source heat pump is to load through the ground for the building heat to heat exchange with the soil in summer to heat transfer into the building the soil, the soil in the winter then the heat transferred to the building, therefore, underground heat exchanger is the ground source heat pump equipment is essential. Ground source heat pump heat exchanger sub-horizontal and vertical type two, use horizontal or vertical-type heat exchanger by the available land area, soil type and excavation costs may be, if a lot of land, and digging to facilitate , then the level of economical heat exchanger. Vertical heat exchanger area of relatively less, so tight in the city where such land is used most of the vertical-type heat exchanger, it requires higher mechanical drilling and filling technology, the project cost is higher relative . Currently, the city ground source heat pump in the construction of all types with vertical ground heat exchangers, vertical heat exchanger cost impact of technical factors are mainly the following aspects.
