However, this system also has two limitations. One is that the area of use is severely limited (it is only suitable for openings, that is, strong rock formations, such as granite, quartz sandstone, etc., and the covering layer is not thick (within 30m) and the covering layer is a strong rock formation. area), and secondly, there is a problem that the vertical buried pipe ground source heat pump system does not exist—heat penetration

Abstract
The invention relates to the technical field of heating ventilation air conditioning industry ground source heat pumps and domestic hot water supplying, in particular to a combined type ground source heat pump system and a method for solving recharging of a water source heat pump. The combined type ground source heat pump system comprises a surface covering layer (1), a water bearing bed (2), a competent bed rock (3), a clay ball refilling layer (4), a gravel padding layer (5), a cement grouting layer (6), an upper casing pipe layer (7), a filtering pipe (8), a steel casing pipe (9), an open hole side wall (10), an immersible pump (11), a plate heat exchanger (12), a secondary side circulation pump (13), a ground source heat pump unit (14), a user side circulation pump (15), a user tail end (16), a diversion valve (17), a common inverted well (18) and a related pipeline. The combined type ground source heat pump system has the advantages that the water source heat pump recharging is thoroughly solved, and the single well circulation system thermal breakthrough is achieved. The heat exchanging efficiency is high, the occupied space is small, the construction period is short, the adaptability is high, the system cost is low, and the service life is long.
Description
technical field [0001] The invention relates to the field of ground source heat pumps in the HVAC industry and the technical field of domestic hot water supply, in particular to a composite ground source heat pump system and a water source heat pump recharge method. Background technique [0002] In recent years, environmental problems have become increasingly serious, energy saving has become a trend, and environmental protection has become an irresistible trend. In the field of building energy conservation, ground source heat pumps, as an energy-saving, environmentally friendly and green central air-conditioning system, have attracted more and more attention. However, as we all know, vertical buried pipe ground source heat pump system (GCHP) and water source heat pump system (GWHP) are currently mainly used in China. The vertical buried pipe system has a high initial investment, which restricts further promotion and application. Water source heat pump system Due to the dif...
