The refrigerant is the blood of the compressor. The purity of the refrigerant is particularly important for the cold storage refrigeration equipment. The most obvious phenomenon is: the cold storage filled with high-purity refrigerant, the…
R134 has a certain greenhouse effect R600a has no greenhouse effect.
R134 has a certain greenhouse effect. R600a has no greenhouse effect. 2. R600a’s evaporating pressure, condensing pressure, and exhaust temperature are lower than R-134a. The lower liquid density of R600a refrigerant makes its charge capacity…
The application characteristics of R22 Freon and R134a Freon
1. The global warming potential (GWP) of R134a Freon is 0.25. The global warming potential of R22 Freon is 0.36. Both are greenhouse gases. 2. The ozone depletion potential (ODP) of R134a refrigerant is 0.…
Refrigerants can be divided into three categories: single working fluid
Refrigerants can be divided into three categories: single working fluid refrigerants, non-azeotropic mixed refrigerants, and azeotropic mixed refrigerants. No matter whether the single-working-substance refrigerant is gaseous or liquid, its composition will not change, so it…
R-134a refrigerant alias R134a HFC134a HFC-134a tetrafluoroethane
R-134a refrigerant, alias R134a, HFC134a, HFC-134a, Chinese name , English name 1,1,1,2-tetrafluoroethane, chemical name 1,1,1,2 Ethane, the molecular formula CH2FCF3. Because R-134a belongs to HFC substances (non-ODS substances Ozone-depleting Substances)-it does not destroy the ozone…
R410A needs to be filled in liquid, and the thickness of the copper tube
Because R22 and R410A have different compositions and pressures, R410A needs to be filled in liquid, and the thickness of the copper tube of the machine is also different, so it is forbidden to mix…
If the refrigeration engineer with experience or careful observation
This method does show that there are bubbles that indicate a lack of refrigerant, but we must understand that the pressure loss of the liquid pipe can also cause bubbles. If the pressure loss of…
R-134a is the most widely used medium and low temperature environmentally friendly refrigerant.
R-134a refrigerant, alias R134a, HFC134a, HFC-134a, tetrafluoroethane, Chinese name tetrafluoroethane, English name 1,1,1,2-tetrafluoroethane, chemical name 1,1,1,2 tetrafluoroethane Ethane, the molecular formula CH2FCF3. Because R-134a belongs to HFC substances (non-ODS substances Ozone-depleting Substances)-it does not destroy…

All the refrigeration system are designed to run without moisture
All the refrigeration system are designed to run without moisture and non-condensable gases else it may not work as designed and is likely to fail prematurely. Presence of moisture in the air conditioning system may…
