"Vacuumize " this word, pushing forth a few years, average user listens to had not heard of repeatedly. As frequency conversion air conditioning arisen, just more and more people knew air conditioning installation wants vacuumize. So, why to want vacuumize after all? Be all air conditioning need vacuumize? We solve these two problems today. (next graphs: In vacuumize exercise)
Air conditioning conduit is not closing before installation, regular meeting is put in a lot of air in the conduit after so installation is finished. So called vacuumize, pump the air in conduit namely. So we might as well think conversely: If do not pump these air, what can you produce?
1. most the mainest harm, it is R410a refrigeration agent belongs to agent of a kind of mixture refrigeration, the scale of all sorts of composition asks inside extremely tall. If air exists inside conduit, with respect to the composition that can destroy the part in former refrigeration agent and scale, bring about refrigeration agent pressure finally to produce change, affect refrigeration result, lose refrigeration ability even.
2. air runs in air conditioning system (the course according to refrigeration agent) , can bring about compressor vent temperature to lift, affect compressor life.
There is vapor in 3. air, vapor can become a liquid in the condensation in the system, enter compressor labor oily pool finally. Then attenuant refrigerator oil, affect the result of refrigerator oil, cause compressor damage finally.
... harm still has a lot of, the mainest is this at 3 o'clock, listed what remain one by one no longer.
Whether all air conditioning wants vacuumizeWe also a moment ago said, not the harm with the mainest vacuumize destroys R410a refrigeration agent namely. To average R22 refrigeration agent, composition is more onefold, accordingly although enter a few air, affect to refrigeration also too won't big.
Frequency conversion air conditioning is general and applicable R410a refrigeration agent -- agent of this kind of refrigeration more environmental protection, be thought to be able to replace R22 refrigeration agent in future by person much person -- accordingly must vacuumize.
The air conditioning that decide frequency uses R22 refrigeration agent commonly, did not have so " air destroys refrigeration agent " this says. Because this decides frequency air conditioning to be when installation need not vacuumize -- but other harm or some, just need not vacuumize, if can vacuumize is better of course.
In addition, no matter install what air conditioning, need to examine a manual ahead of schedule, agent of refrigeration of affirmatory air conditioning is phyletic -- do not eliminate to a few decide frequency air conditioning to also use R410a refrigeration agent.
Conclusion: Whether does air conditioning need vacuumize, have nothing to do with calm frequency or frequency conversion, concern with refrigeration agent!
