Foreword

This standard replaces GB/T 14294-1993 "modular air conditioning units" and GB 13326-1991 "noise air handling units Limit. " This standard and GB/T 14294-1993 and GB 13326-1991 main technical differences compared as follows. --- Performance Indicators. external static pressure when dry conditions is not less than 90% of the rated value; when wet condition rating of not less than 85%; and cooling capacity Rated heat input of not less than 95%; and increase the housing deformation rate and quantity of water resistance requirements. --- Unit noise is determined by the amount of wind and fully hydrostatic unit. --- Test Method for Change. the amount of cooling and heating load test, in addition to loop duct air enthalpy method, increase the room air enthalpy method; unit Leakage rate increased negative pressure means; the unit amount of wind pressure tests using the clear duct pitot tube and multi-air flow nozzle method; increase housing Deformation test points positive and negative pressure test. The Standard Appendix A, Appendix B, Appendix C, Appendix D, Appendix E is a normative appendix, Appendix F for the informative appendix.
