The invention discloses refrigerating glass provided with conical through holes. The evenly-distributed conical through holes are formed in the glass. The aperture size of the conical through holes is 0.01%-200% of the thickness of the glass, the smallest size of the small-aperture end of each conical through hole is 0.01% of the thickness of the glass, and the largest size of the large-aperture end of each conical through hole is 200% of the thickness of the glass; the distance between the conical through holes is 0-10 times the aperture of the big end of each conical through hole, and the inclination angle of each conical through hole is 30-75 degrees. Before the glass is formed, the evenly-distributed conical through holes are formed in the glass through a template; and the glass provided with the conical through holes is applied to a glass window, the large-aperture side of the glass is located outdoors, natural wind enters a room through the conical through holes in summer, and thus the indoor temperature is decreased according to the throttling expansion principle. The glass provided with the conical through holes is simple in structure, convenient to use and free of electricity consumption, and no refrigerant is needed; and adverse effects, such as pollution and the greenhouse effect, caused by adoption of refrigerants are reduced, and meanwhile, resources are saved.
