The invention discloses a combined air cooling system of a rescue capsule, comprising a liquid carbon dioxide refrigeration system, a throttling expansion refrigeration system and an evaporation cooling system, wherein the liquid carbon dioxide refrigeration system, the throttling expansion refrigeration system and the evaporation cooling system are connected to form a combined refrigerating system through pipe lines. The combined air cooling system of the rescue capsule generates a Joule-Thomson refrigerating effect through the utilization of the differential pressure between the high pressure generated after the gasification and heat absorption of working media such as liquid carbon dioxide, liquid nitrogen or Freon, and the atmospheric pressure, and generates an evaporative cooling effect through the utilization of gaseous carbon dioxide of which the relative humidity is lower after throttling expansion. Since the combined air cooling system of the rescue capsule fully utilizes the potential heat, the post-gasification pressure energy and the lower relative humidity of the liquid carbon dioxide, the refrigeration amount of the liquid carbon dioxide of unit mass is greatly improved. Under the condition of meeting the environmental temperature of the capsule, the storage volume of the liquid carbon dioxide is decreased, and the space in the capsule is saved.
Description
technical field [0001] The invention relates to the technical field of air-conditioning and refrigeration, in particular to an air cooling system for an emergency cabin. Background technique [0002] When a catastrophic accident occurs underground, the air cooling system of the rescue cabin can provide the necessary survival temperature for the miners hiding in the rescue cabin, so that the ambient temperature in the cabin can be kept below 30°C, which basically meets the requirements of human survival. The ejector refrigeration system described in Chinese patent ZL200910248593.2 is an open refrigeration system with liquid carbon dioxide as the working fluid, water as the refrigerant, and no condenser. The invention patent makes full use of the latent heat of liquid carbon dioxide and the pressure energy after its vaporization in theory, increases the cooling capacity of liquid carbon dioxide per unit mass, produces a good refrigeration effect, reduces the storage capacity o...
