Truck refrigeration units are familiar to everyone, so what steps does he have when selecting a model? What else needs attention? Today we are here to learn this knowledge.
Determine whether to use an independent unit or a non-independent unit
The independent unit is generally used in large and medium-sized vehicles. Since the unit compressor requires a large amount of power, it needs to be equipped with an independent engine drive without taking up the power of the vehicle itself. On the contrary, the non-independent unit is mainly used in small-scale distribution vehicles in the city. The power required by the unit compressor is small, and there is no need to separately configure the engine. The engine drive of the vehicle itself does not have a great influence on the power of the vehicle. In addition, the actual use of the vehicle should be considered to determine whether to select an independent unit or a non-independent unit.
Determine the ambient temperature used by the unit
The required unit will vary depending on the ambient temperature. For example, in areas with high summer temperatures, the cabin needs more cooling to maintain the same temperature, so the cooling capacity of the selected chiller will increase accordingly. The selection table only lists the unit selection at ambient temperatures of 30 ° C and 40 ° C. The selection of other ambient temperatures can be calculated using the interpolation method.
Select the set temperature in the compartment
The set temperature in the compartment is also the transport temperature of the cargo, which can be determined based on the transport temperatures of the various cargoes listed above. In the selection table, the green color block identifies the unit selection range of the frozen goods, the red color block identifies the unit selection range of the refrigerated goods, and the yellow color block identifies the unit selection range of the unpre-cooled goods.
