Container refrigeration apparatus

Abstract

A container refrigeration apparatus includes a cooler including a compressor, a radiator, an expansion mechanism, and an evaporator and being configured to perform, by the evaporator, a cooling operation of cooling an inside of a container, a ventilator configured to supply outside air into the container, and a processor configured to control the cooler and the ventilator, wherein the processor is configured to adjust a cooling capability of the cooler, based on a ventilation cooling load that is a cooling load in accordance with a ventilating operation of the ventilator.

 control the ventilator so that an amount of ventilation by the ventilator approaches a first ventilation amount, and   adjust the cooling capability of the cooler, based on an internal cooling load that is a cooling load inside the container and the ventilation cooling load according to the first ventilation amount.   
     
     
         3 . The container refrigeration apparatus of  claim 2 , wherein the processor is configured to execute:
 a first control of determining a first cooling capability of the cooler, based on the internal cooling load and the ventilation cooling load according to the first ventilation amount,   a second control of causing the amount of ventilation by the ventilator to approach the first ventilation amount after the first control; and   a third control of causing the cooling capability of the cooler to approach the first cooling capability after the first control.   
     
     
         4 . The container refrigeration apparatus of  claim 1 , wherein the processor is configured to perform a first limiting operation of limiting a rate of change in an amount of ventilation by the ventilator so that an index indicating a rate of change in the cooling capability of the cooler in accordance with the ventilating operation of the ventilator is lower than or equal to a predetermined value. 
     
     
         5 . The container refrigeration apparatus of  claim 4 , wherein the processor is configured to execute the first limiting operation when a first mode is selected through an operation of an input. 
     
     
         6 . The container refrigeration apparatus of  claim 1 , wherein the processor is configured to control the ventilator, based on the cooling capability of the cooler. 
     
     
         7 . The container refrigeration apparatus of  claim 6 , wherein the processor is configured to perform a second limiting operation of limiting an amount of ventilation by the ventilator when an index indicating the cooling capability of the cooler is greater than a predetermined value. 
     
     
         8 . The container refrigeration apparatus of  claim 7 , wherein the processor is configured to perform the second limiting operation when a second mode is selected through an operation of an input. 
     
     
         9 . The container refrigeration apparatus of  claim 2 , wherein the processor is configured to perform a first limiting operation of limiting a rate of change in an amount of ventilation by the ventilator so that an index indicating a rate of change in the cooling capability of the cooler in accordance with the ventilating operation of the ventilator is lower than or equal to a predetermined value. 
     
     
         10 . The container refrigeration apparatus of  claim 3 , wherein the processor is configured to perform a first limiting operation of limiting a rate of change in an amount of ventilation by the ventilator so that an index indicating a rate of change in the cooling capability of the cooler in accordance with the ventilating operation of the ventilator is lower than or equal to a predetermined value. 
     
     
         11 . The container refrigeration apparatus of  claim 2 , wherein the processor is configured to control the ventilator, based on the cooling capability of the cooler. 
     
     
         12 . The container refrigeration apparatus of  claim 3 , wherein the processor is configured to control the ventilator, based on the cooling capability of the cooler. 
     
     
         13 . The container refrigeration apparatus of  claim 4 , wherein the processor is configured to control the ventilator, based on the cooling capability of the cooler). 
     
     
         14 . The container refrigeration apparatus of  claim 5 , wherein the processor is configured to control the ventilator, based on the cooling capability of the cooler.
