Underground energy storage-ground source heat pump combined building energy supply system

Abstract

The invention provides an underground energy storage-ground source heat pump combined building energy supply system, which includes three subsystems, including a cold storage and supply system, a heat storage and supply system and an air-conditioner house system, wherein the cold storage and supply system includes a wind plate, a cold storage buried pipe group, an ice storage pool, a cold-zone circulating water pump, a direct supply cold end inlet valve, a direct supply cold end outlet valve, an ice storage pool inlet valve, an ice storage pool outlet valve, a cold storage zone inlet valve, a cold storage zone outlet valve, a surface water inlet valve, a surface water outlet valve and a connecting pipeline; and the heat storage and supply system includes a floor board heating, a heat storage buried pipe group, a solar collector, a wax storage pool, a hot-zone circulating water pump, a direct heat supply end inlet valve, a direct heat supply end outlet valve, a wax storage pool inlet valve, a wax storage pool outlet valve, a heat storage zone inlet valve, a heat storage zone outlet valve, a heat collection inlet valve, a heat collection outlet valve and a connecting pipeline. The underground energy storage-ground source heat pump combined building energy supply system is provided with two tail ends and independent cold and heat sources, and can avoid the geo-temperature field unbalance caused by load difference at winter and summer.

Description

technical field [0001] The invention is specifically an inter-seasonal energy storage and energy supply system that provides cold and heat energy for villa buildings. Background technique [0002] At present, under the condition of tight energy supply and increasingly serious greenhouse effect, it is imminent to develop renewable energy utilization technology. Especially in the field of building energy use, the use of new energy sources has received widespread attention, such as the use of solar energy, wind energy, and geothermal energy. In the utilization of renewable energy, the most widely used technology is the ground source heat pump technology in the utilization of shallow geothermal energy. This technology is a heat pump system that uses underground soil as a low-level heat source for heat pumps, and transfers heat from a low-temperature position to a high-temperature position by inputting a small amount of high-grade energy (such as electric energy). At the same t...
