REFRIGERATION SYSTEM FOR AIRCRAFT

摘要

A refrigeration system (200) for aircraft is provided, which includes: a first stage heat exchanger (102) for receiving hot bleed air from an engine; a second stage heat exchanger (106) with an inlet communicated with an outlet of the first stage heat exchanger (102) and an outlet communicated with an inlet of a mixing chamber; a valve (204) is arranged between the outlet of the second stage heat exchanger (106) and the inlet of the mixing chamber; sensors (210, 212) senses at least the temperature of environment air; and a controller (120) receives parameter from the sensors (210, 212) which are compared with a stored preset range, if the parameter is within the preset range, the controller (120) opens the valve (204), and the hot bleed air enters into the mixing chamber after passing through the first stage heat exchanger (102), the second stage heat exchanger (106) and the valve (204) in order. The refrigeration system (200) can save energy and improve economic performance.
