Abstract (en)
[origin: EP2075516A2] An operation control method of a refrigeration unit for land transportation in which a plurality of evaporator units are parallelly connected into a refrigerant circuit (10) for circulating a refrigerant by a compressor (11) driven by a dedicated drive source, and a plurality of different transport temperatures can be respectively created for a plurality of freezing sections which are distributedly arranged with the plurality of evaporator units, comprising: employing throttle mechanisms whose opening degrees are adjustable, as well as providing a low pressure sensor (18) which detects the evaporating pressure of the refrigerant from the evaporator units, for the refrigerant circuit (10); and performing a priority control for lower setpoint temperature which preferentially distributes the refrigerant to an evaporator unit having a lower setpoint temperature, when a plurality of operation requests have been made for a plurality of the evaporator units, during a various temperature cooling operation having different setpoint temperatures for the respective freezing sections.
