Standard Test Method for refrigerant desiccant
1 Scope
This standard specifies the test methods desiccant for drying the refrigerant, test principle employed under certain temperature conditions, so
The moisture content of the desiccant is known to be measured held in contact with the refrigerant, after equilibrium is reached, the determination of the moisture content of the refrigerant.
This standard applies to test methods to test the desiccant, testing and assessment on the use of desiccant dryers, see GB/T 23684-
2009.
2 Normative references
The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent
Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research
Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard.

3 Terms and Definitions
The following terms and definitions apply to this standard.
3.1
The solid can adsorb water, and which itself does not dissolve in the refrigerant working fluid used.
3.2
At standard temperature, into contact with the desiccant long enough to achieve a particular water content after equilibrium. Equilibrium point dryness refrigeration
Agent trap mass contained in the mass of one million (ppm) to represent.
3.3
Of water at a given temperature, when the liquid refrigerant passes through the desiccant to maintain a certain equilibrium point dryness, desiccant adsorption
the amount. Press desiccant manufacturing manual activation of the water content in grams per 100g aqueous desiccant activated to measure.
4 Test conditions
Standard Test Method 4.1 applies specifically to the refrigerant in the desiccant and balance each other's conditions, and the determination of moisture adsorption desiccant
The water content of the refrigerant.
4.2 This standard only due to the state of equilibrium at a given temperature, and therefore did not consider the impact of a desiccant container containing designs. but
Yes, this standard describes the method, after some modifications, can be tested in full dress in the desiccant dryer means to determine when it
Adsorption of water containing a known quantity of the refrigerant in equilibrium state. 23684-2009 modifications set forth in GB/T .
4.3 Standard Test Methods desiccant desiccant in equilibrium with the liquid refrigerant.
4.4 standard does not consider the drying rate, ensure that the measure is in equilibrium conditions.
Standard Test Method 4.5 is not considered desiccant physical properties, such as particle size, the nature of the dust, the hardness and the particular shape (i.e., molded
Or granules).
This standard applies to all or phosphorus pentoxide drying agent unreactive refrigerant, but not included in the low-pressure part of the device
It will be condensed into a liquid refrigerant.
