Only in this way, the expected "cooling capacity", "heating capacity", "APF (energy efficiency ratio)" and "IPLV (cooling overall performance coefficient)" can be achieved when the air conditioner is operated.
However, different enterprises execute different process standards for different unit systems, and taking table one as an example, the side-air-out multi-connected unit for filling the unit system with R410A refrigerant requires that the vacuum degree of the system must reach 20pa to be qualified, and then the refrigerant filling process can be performed;
