refrigerating and space engineering; on-board refrigerators for storage of products during protracted operation of manned spacecraft. SUBSTANCE: refrigerator has heat-insulated cabinet, thermostat, air cooler hydraulically connected with condenser which is made in form of radiating panel with the following optical characteristics: As<=0,2 and epsi>=0,9, where As is solar energy reflection; epsi- is surface emissive factor; it is mounted on the outside of spacecraft pressure compartment. Air cooler and condenser are included in their own closed hydraulic loops provided with flow activator. Loops are interconnected by means of intermediate heat exchanger. Flow activator of hydraulic loop of air cooler is connected with thermostat by means of control channel. EFFECT: reduced power requirements due to use of natural source of cold-space; reduced noise and vibration levels. 1 dwg |
