The invention discloses a one-man
refrigeration and
breathing device, for use by personnel working in unlivable environments to ensure the safety and comfort of the personnel. The one-man
refrigeration and
breathing device comprises an oil-free
air compressor (1), an air handling device (2), a
breathing mask (3), a vortex tube
refrigeration device (4), one-man refrigeration clothes (5) and a connecting pipeline (6), wherein the oil-free
air compressor (1) is connected with the air handling device (2) and the vortex tube refrigeration device (4) through the connecting pipeline (6); the air handling device (2) is connected with the breathing
mask (3) through the connecting pipeline (6); the vortex tube refrigeration device (4) is communicated with the interior of the one-man refrigeration clothes (5) through the connecting pipeline (6). The one-man refrigeration and breathing device can ensure that the temperature and the
humidity of inspired air of the working personnel are within a
normal range and the air is clean, so as to prevent a
human body from suffering from high temperature and
high humidity; meanwhile, the one-man refrigeration and breathing device can reduce an
apparent temperature of the
human body to ensure the comfortableness of the working environments, is simple in structure, adopts a
modular design, is small in size and light in weight, uses air as a refrigeration medium, thereby being safe and environment-friendly, and having a broad application prospect.
