Well heat storage method and system of solar heat pump heating and hot-water supply system

Abstract

The invention relates to a well heat storage method of a solar heat pump heating and hot-water supply system, comprising the following steps of: storing heat energy output by a solar heat collection device into a well-shaped aritificial water body, wherein the well-shaped aritificial water body comprises a domestic water well, a circulating well of a ground source heat pump and more than two well-shaped objects mutually communicated on the ground or underground and does not comprise a water body, which takes meter as a measuring unit and has the ratio of depth to sectional area to be less than 3.1, or an opened water body, and the well-shaped aritificial water body is called as heat storage well for short; and supplying the heat energy to a heating and hot-water supply facility by takingthe water in the heat storage well as a heat source through a heat pump unit. The well heat storage solar heat pump heating and hot-water supply system manufactured according to the method comprises the solar heat collection device, the heat pump unit and the heat storage well. The well heat storage solar heat pump heating and hot-water supply system is characterized in that the water in the heatstorage well, which is connected with an evaporator or a condenser of the heat pump unit in a heat exchanging way, is connected with the solar heat collection device in the heat exchanging way. The invention has the advantage of finding a matched intermediate heat storage facility for the combination of solar energy and a heat pump. The embodiment is given by combining with a figure in the specification.

Description

technical field [0001] The invention relates to a solar heat pump heating and hot water system well heat storage method and system. Background technique [0002] The heat pump heating system uses the solar heat collector as a low-temperature heat source to improve the energy efficiency ratio of the heat pump unit. But the heating load is often out of sync with the solar intensity. During the day, the sunlight is strong, but the heating load is low, and the solar thermal energy is rich but cannot be effectively stored; in rainy and snowy days and at night, the heating load is high, but there is not enough solar energy available at this time. Contents of the invention [0003] The object of the present invention is to provide a solar heat pump heating and hot water system well heat storage method and system. [0004] Solar heat pump heating and hot water system well heat storage method: Calculate the required area of ​​solar collectors according to the heating and hot wate...
