Design of a villa ground-source heat pump central air conditioning system
Abstract: With the development of science and technology, more and more technology will be applied to air-conditioning energy saving. Ground source heat pump technology in the villa district installation greatly reflects its advantages of saving energy, this technology is in line with the national policy on energy saving and emission reduction. This paper based on analyzing the advantage of energy-saving ground-source heat pump air conditioning system, for the design of ground-source heat pump central air conditioning system in a villa in Nanjing, which can meet the summer cooling and winter heating requirements. Because Nanjing is hot in summer and cold in winter, heat pump should be designed with both summer cooling and heating in winter, and the heat transfer from the general underground pipe group is higher in winter than in summer, if it can meet the requirements of general summer then winter can also meet the requirement, so the device according to the summer condition design. The design, building heating load calculation based on the design conditions, followed by the building's air system, water system design and equipment selection, calculation and selection of floor heating and ground heat exchanger, and finally take into account thethe muffler and damping of the building.
Keywords: Energy; Ground source heat pump; HVAC; Buried pipe; Ground source heat pump air conditioning system
