Document Type and Number:
WIPO Patent Application WO/1999/022187
Kind Code:
A1
Abstract:
This invention relates to a phase-changeable and non-heat refrigeration process and apparatus thereof. The apparatus is composed of multi-stages refrigeration cycle. The first stage compresses vapour, the other stages liquify the vapour of gelf stage by using cool quantity in lower temperature of preceding stage to effect refrigeration cycle. A compressor and a condenser of the first stage are immersed in the liquid medium of next stage, heat is consumed by latent heat of vaporation thereof, so that temperature of condensation is approximately temperature of vaporation, to refrigerate and supply cooling. The temperature of respective stage rises gradually in connective order. The median stages multiply refrigeration, the last stage cools a load. This system hasn't heat leaking outside, it ameliorates refrigeration efficiency.
