AIR SUPPLY SYSTEM FOR A REFRIGERATION UNIT OF REFRIGERATED TRANSPORT.

摘要

P The air supply system (20) according to the present invention for a refrigeration transport refrigeration unit (10) comprises a source (12) of double speed motive power, a compressor (14), a condenser (16), an evaporator (18), and first and second air supply blowers (26, 30) for the condenser and the evaporator, respectively. The speed of the first blower (26) is directly proportional to the speed of the motive power source and the second blower (30) is driven by an adjustable speed arrangement (32). This arrangement (32) includes an electric clutch (54) and a one-way clutch (45). The electric clutch, when energized, selects a predetermined speed for the evaporator blower which is greater than the speed of the condenser blower. /P
