This standard applies to the use of desiccant dryers. As the desiccant performance varies with activity, moisture content test methods specified in this standard applies both to test "new dryer, " also applies to the contents required by the manufacturer had reactivated desiccant dryers. This standard applies to the use of the system halogenated refrigerants boiling point below 20��C under standard atmospheric pressure. This standard does not apply to the dryer following performance indicators: the physical characteristics of a) desiccant, chemical characteristics b) of the dryer, absorbing mechanism c) of the dryer, d) the ability to filter drier, e) dryer acid adsorption, f) are not used for dryer performance liquid pipelines, g) drying speed, h) by the system size, affect i) oil on dryer performance, impact of potential freezing and chemical activities of the water content of the dryer. This standard does not specify the temperature, equilibrium point dryness, drop and other standard conditions, these values ??refer to ARI 710 standard.

The technical content of the standard ANSI/ASHRAEStandard63.1-1995 (RA2001) consistent. The editorial changes made the following standard. --- In the structure of this standard Chapter 1 contains the ANSI/ASHRAEStandard63.1-1995 (RA2001) of Chapter 1 And Chapter 2, all the clauses and contents of the same order as the original standard, numbered differently; --- With a decimal point '. 'Instead of a comma as the decimal point,' '; --- The standard delete the original standard in English units, the uniform application of the International System of Units; --- For ease of use, increase in Appendix A lists the contents of the standard reference standard terms. Appendix A of this standard is an informative annex. The standard proposed by the People's Republic of China Ministry of Commerce. This standard by the National Standardization Technical Committee refrigeration and is responsible for interpretation. This standard was drafted. China Refrigeration Institute, Xi'an Jiaotong University, the National Commercial Refrigeration Equipment Quality Supervision and Inspection Center. The main drafters of this standard. Li Liansheng, Wang Fei from Liu Xiaopeng, Chang Lin, Xiao Yang. Test method for control of refrigerant dryers1 ScopeThis standard specifies the test method to determine the fluid flow rate control refrigerant dryer and moisture performance characteristics. This standard applies to the use of a desiccant dryer. Since the desiccant performance with its activity and changes in the water content of the test methods specified in this standard is applicable to both test "new dryer," also Built by the manufacturer applies to require re-activation through the desiccant dryer. This standard applies to the use of halogenated hydrocarbon system refrigerant boiling below 20 ℃ under normal atmospheric pressure. This standard does not apply to the following performance indicators for the dryer. Physical characteristics a) a desiccant; b) chemical properties of the dryer; c) absorbing mechanism of the dryer; d) the ability to filter dryer; e) for acid adsorption dryer; f) are not used for the dryer performance liquid pipelines; g) drying speed; h) by the size of the system, the potential problem of the freezing and chemical activities on the water content of the dryer; i) oil on dryer performance. This standard does not specify a temperature, equilibrium point dryness, pressure drop and other standard conditions, these values \u200b\u200brefer ARI710 standards (see Appendix A).2 Terms and definitionsThe following terms and definitions apply to this standard. 2.1 The solid can adsorb water, and which itself does not dissolve in the refrigerant working fluid used. 2.2 The device is equipped with a drying agent. In the liquid pipe refrigeration systems, primarily for adsorbing moisture into the system. 2.3 At a specific temperature, contact with a desiccant for long enough to achieve a particular water content after equilibrium. Equilibrium point dryness refrigeration Agent trap mass contained in the mass to represent one million. 2.4 Pressure dryer inlet and outlet refrigerant difference unit. kPa. 2.5 Rated pressure drop, given the refrigerant mass flow rate through the dryer. When the liquid temperature is 43 ℃ per second flow through the refrigerant Quality expressed in units. kg/s. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 23684-2009_English be delivered?Answer: Upon your order, we will start to translate GB/T 23684-2009_English as soon as possible, and keep you informed of the progress.
