2. Product details:

R422D is a simple to use, the ODP zero (ozone depletion potential) of HFC refrigerants, can directly replace R - 22 at moderate temperature in direct expansion (DX) refrigeration equipment, including business systems, supermarket and fixed direct expansion (DX) type air conditioning equipment, including DX water-cooling chiller.

Product information

ASHRAE #

R422d

Replacement:

R - 22

Application:

Medium temperature and low temperature of commercial, industrial, direct expansion refrigeration system (DX), including:

1) catering refrigerated 2) supermarket display case 3) food storage and processing 4) ice machine

Household, commercial air conditioner (AC) :

Direct expansion (DX) type is the best choice for water-cooled machine

Advantages:

Provide a simple, efficient and economic directly replace - R - 404 - a, R - 507, R - 407 - c is easier to replace

HFC refrigerants, ODP value is zero

Compatible with traditional and new lubricating oil. In most cases, the process of replacement without replacement lubricating oil type

So far, all of the field test was successful, and without temperature control expansion valve replacement - may need to adjust the degree of superheat

Still can continue to use the existing equipment

Than the R - 404 - a and R - 404 had a 30% lower global warming potential (GWP)

After filling is used, if discover the refrigerant in the system capacity is insufficient, can be directly to make up, without row has complete pump refrigerant

Performance:

In most systems, has a very close to that of R - 22 refrigeration capacity and efficiency

Than R - 22 lower exhaust temperature, can prolong the life of compressor

Under the condition of low temperature, than R - 22 refrigeration capacity and efficiency as high as 14% up to 8%

In medium temperature conditions and the degree of supercooling is 6 ° C, the R422D refrigeration energy consumption about 5% less than R - 22, but the efficiency and R - 22

3. Product selection deadline:

R422D refrigerant ODP is zero, so is not affected by the Montreal "draft regulations obsolete material in control.

4. Lubricating oil use advice:

R422D compatible with traditional and new lubricating oil, including: mineral oil (MO), alkyl benzene lubricating oil (AB), and ester lubricant (POE). In most cases, the replacement process without replacement lubricating oil type.
