Economical Analysis of a Groundwater Source Heat Pump with Water Thermal Storage System
MetadataShow full item record
The paper is based on a chilled and heat source for the building which has a total area of 140000m2 in the suburb of Beijing. By comparing the groundwater source heat pump of water thermal storage (GHPWTS) with a conventional chilled and heat source scheme in economical, technical, and environmental aspects, it is determined that the scheme of the groundwater source heat pump has better energy efficiency than others. The GHPWTS can take full advantage of the heat source from groundwater and benefit of electricity difference pricing during a day. Its character is a combination of a strength and another strength. It is the lowest cycle cost of all chide and heat source schemes. The GHPWTS has the best economic benefit and runs stably and reliably. Its advantage is clearly compared with other schemes. There is a real value for the project that is similar to the characteristic of this project and the condition of the water source.
