Earth-cooled room temperature adjusting method

Abstract

The invention discloses an earth-cooled room temperature adjusting method. Indoor temperature adjustment is achieved by a cyclic process that liquid medium releases heat underground and then absorbs heat inside a room. The earth-cooled room temperature adjusting method comprises the concrete operations as follows: the liquid medium is driven to circulate by power; the liquid medium firstly achieves heat exchange to release heat together with low-temperature soil in the underground, then carries out heat exchange with indoor air inside the room, and absorbs the heat of the indoor air, so as to adjust the indoor temperature. By adopting the earth-cooled room temperature adjusting method, the liquid medium carries out heat exchange together with the underground low-temperature soil in the deep underground to release heat, and then carries out heat exchange together with the indoor air to absorb heat, so as to reduce the indoor temperature; only a little of electric energy is provided for circulating of the liquid medium in the entire process, so as to achieve cooling. Compared with an air conditioner, a lot of electric energy is saved; earth cold is also fully utilized.

Description

technical field [0001] The invention relates to the field of industrial refrigeration, in particular to a ground-cooled room temperature adjustment method. Background technique [0002] Due to the improvement of people's living standards, air conditioners are becoming more and more popular. However, due to the high energy consumption of air conditioners, the concentrated use of air conditioners has caused the gap between peak and valley electricity consumption in cities to increase day by day. In order to cut peaks and fill valleys of the power grid, energy storage air conditioners are now being advocated. A better option is to use ice storage systems, which can save a lot of operating costs for users. However, the ice storage system also has its own disadvantages. For example, the initial investment is large, and the refrigeration unit has a very low evaporation temperature during ice production, and its COP is reduced. Therefore, from the perspective of energy saving, ice...
