Energy storage and temperature change type air conditioning method with underground reservoir and water source heat pump, and the dedicated device thereof

Abstract

The present invention discloses a variable temperature air-conditioning method using underground reservoir and water-source heat pump with energy-storage and its specialized equipment, which includes a geothermal heat exchanging cycling loop and an air-conditioning heat exchanging cycling loop, wherein the air-conditioning heat exchanging cycling loop includes a variable temperature air-conditioning heat exchanging cycling loop. In the geothermal heat exchanging cycling loop, the water-source heat pump exchanges energy with energy-storage tanks, and in the air-conditioning heat exchanging cycling loop, the energy-storage tanks exchanges energy with an air-conditioning load loop.

BACKGROUND OF THE PRESENT INVENTION[0001]1. Field of Invention[0002]The present invention relates to a water-source heat pump, and more particularly to a variable temperature air-conditioning method using underground reservoir and water-source heat pump with energy-storage and its specialized equipment.[0003]2. Description of Related Arts[0004]Water-source heat pump is an effective energy-saving heating and cooling air-conditioning system for buildings by using low-ground heat including underground or surface water. The application of water-source heat pump technology has to be limited because of the following problems during the utilization of the underground and surface water. Well-drilling and underground recharge is high cost. The surface water is substantially subject to the environment temperature. Heat exchange affects the ecological environment.[0005]A buried-tube type of water-source heat pump system is to bury tubes for exchanging heat from rock and soil to a thermal stora...

Problems solved by technology

The application of water-source heat pump technology has to be limited because of the following problems during the utilization of the underground and surface water.

Well-drilling and underground recharge is high cost.

The shallow-buried tubes will be greatly influenced by the surface temperature and solar radiation, so that the system has low stability.

The deep-buried vertical tubes adopt high pressure polyethylene plastic U-shaped tube, so that the costs on related materials and ground-hole drilling are high.

Besides, the buried-tube type of water-source heat pump system demands high quality heat exchanger and geological structure, has low energy level per unit in heat exchange, and has higher system investment than other types of water-source heat pump, so that it is generally applicable to residential buildings with small unit and low temperature control standard, and hardly applicable to large air-conditioning engineering with high temperature control stability and standard.

When main heating pump is faulty, the system still ca
