GB/T 19933.4-2014 Earth-moving machinery—Operator enclosure environment—Part 4:Heating, ventilation and air conditioning(HVAC) test method and performance
Abstract
This part of GB/T 19933 specifies a unified test method for measuring the internal environmental temperature of the driver's cab, which is generated by the heating, ventilation, and air conditioning systems operating under specific ambient conditions.
This method cannot determine all the climatic environments in the driver's cab, as the heat load generated by heat sources other than the machine (such as solar energy) will also affect the driver's cab. To more accurately determine the total heat load in the driver's cab, Part 6 of GB/T 19933 should be used in conjunction with this part.
This part specifies the minimum performance level of the heating, ventilation, and air conditioning systems in the machine's driver's cab.
