The receiver-dehumidifier serves in air central air for a filtration, drainage and time storage of a coolant leaving the condenser. The receiver tank is equipped by the mesh filter providing elimination of extraneous particles and pollution and clearing of them of a system path.
Service life of a receiver of a dehumidifier in the modern central airs Infiniti working on coolant R134а makes about 10 years whereas earlier, at use of coolant R-12 receiver replacement should be carried out regularly enough owing to a congestion in it of surplus of a moisture. The design of components of modern systems allows to avoid moisture hit in a path at the expense of use of special additives, sealing elements of the compressor, the latent sealing rings and water-proof hoses.
Each time at a detachment of a receiver or any other components of a refrigerator path cork the open ends choke connections and connecting lines in order to avoid hit in moisture system.
Receiver-dehumidifier replacement in modern central airs should be made only in following cases:
- Compressor jamming;
- Hit in system of metal particles;
