Foreword

GB/T 19933 "moving machinery cab environment" is divided into six sections.

--- Part 1. Terms and definitions;

--- Part 2. Air filter test method;

--- Part 3. Test methods for pressurization;

--- Part 4. heating, ventilation and air conditioning (HVAC) test method and performance;

--- Part 5. Test methods for windshield defrosting system;

--- Part 6. Determination of effect of solar heating.

This section GB/T Part of 419,933.

This section drafted in accordance with GB/T 1.1-2009 given rules.

This Part replaces GB/T 19933.4-2005 "moving machinery - Operator enclosure environment - Part 4. cab air conditioning, heating and (or) Test methods for ventilation. " This portion of the GB/T 19933.4-2005 compared, in addition to editorial changes outside the main technical changes are as follows.

--- Standard name changed to "moving machinery - Operator enclosure environment - Part 4. heating, ventilation and air conditioning (HVAC) test method and performance";

--- Chapter 2, "Normative references" added the appropriate reference standard (see Chapter 2, Section 2 of the 2005 edition);

--- Increasing the relevant terms and definitions (see Chapter 3, Section 3 of the 2005 edition);

--- Remove the 2 "driver comfort curve" (see 2005 edition of Chapter 3);

--- Modify the technical content;

--- Increase the informative Appendix A.

1 Scope

GB/T 19933 provisions of this part of the harmonized test methods to test the ambient temperature inside the cab, in particular the temperature from around Environment provides heating, ventilation and air conditioning systems produce.

This method can not determine all the cab climate, because heat from the machine outside source (such as solar) heat generated negative Holland will have an impact on the driver's cab. In order to more accurately determine the total thermal load inside the cab, GB/T 619 933 and Part Combined with the application of this section.

This section provides the minimum performance level of the machine cab heating, ventilation and air conditioning system.
