The invention discloses an energy-saving air-conditioning system utilizing air in an underground tunnel of a mine. The energy-saving air-conditioning system comprises an air-conditioning unit comprising an external heat exchanger, an internal heat exchanger, a compressor and an expansion valve, wherein the external heat exchanger of the air-conditioning unit is communicated with the underground tunnel of the mine through a circulating air pipe. The energy-saving air-conditioning system can utilize the characteristic of normal temperature all the year round in the mine tunnel and can be used for heating, refrigerating, providing domestic hot water and the like by taking the existing tunnel as a heat (cold) source, so that soil does not need to be excavated again, and an underground water source does not need to be searched again. The energy-saving air-conditioning system is low in cost, has a good energy-saving effect and is good in environment friendliness.
Description
technical field [0001] The invention relates to a heat pump energy-saving air-conditioning system, in particular to an energy-saving air-conditioning system utilizing mine underground tunnel wind. Background technique [0002] With the development of the economy and the improvement of people's living standards, heat pumps have been more and more widely used as an energy-saving air-conditioning equipment. [0003] The working principle of the air source heat pump is to extract heat from the outdoor air during winter heating, transport it to the room to increase the temperature of the indoor air, and absorb heat from the indoor air during summer cooling, and then discharge it into the atmosphere. Create a suitable indoor environment for people's work and life; [0004] Such as Figure 1a , Figure 1b As shown, the water-source heat pump mainly uses groundwater as the heat (cold) source to provide heating, cooling and domestic hot water. When heating in winter, the ground-tem...
