What is refrigerant charging?

All air conditioners and refrigerators rely on the right charge or the amount of refrigerant in their systems to work properly. Refrigerant charging refers to replenishing these gases when the repairs or leaks of the system caused exhausted levels. Refrigeration can be charged with bulky refrigerant containers or charging sets that generally hold enough gas for one charge. In both cases, the refrigerant charging pipes with associated hoses, valves and meters are required to complete the operation. Refrigeration gas is usually carried out through a hopeless service port or a valve mounted in the system.

Air -conditioning units and refrigerators are designed to function properly with a predetermined refrigerant gas charge. Under perfect operating conditions, air conditioning and refrigerators would never require recharge, but leaks sometimes develop that exhausts refrigerant charges. Repairs of these systems also require dischargeVA. During normal operation, there are several fast indicators that indicate the exhausted charge of the refrigerant. These include low system efficiency, noticeably lower temperature from the capacitor fan, topping up the coils and located oily residues on the pipes that may indicate leakage.

If the refrigerant is suspected, the condition should be verified by a set of meters for system pressure; This verification procedure may need to be performed by a qualified technician. If the result is positive, the system should be recharged as soon as possible, as low refrigerant charges place excessive load on the compressor. Most cooling and air conditioning systems will include a service valve to facilitate the system recharge. These valves are usually a Schraeder design that allows refrigerant charging without losing the system. The recharge process is done from the cylinder or the recharge set of relevant refrigerant via the setAva pipes and breakup.

refrigerant charging is performed when the compressor is running to ensure even charging. The system should also have time to warm up normal operating temperatures before charging. When charging, the refrigerant gas should be added to small additions to prevent the system overload. Between each gas input, the system should be allowed to run for a short period of time to allow gas charges to settle and check the pressure. If the pressure within the specifications of the operating specifications of the manufacturer is, the power supply valve on the cylinder may be closed and the distributor from the system.
