The role of air conditioning copper pipe: connecting outdoor unit
and indoor unit, refrigeration pipeline. Air conditioning copper pipe, also known as air conditioning
refrigerant pipe, is the refrigerant through the connection of heat
exchanger, valve, compressor and other main refrigeration
components of the pipeline. The expansion valve of the copper pipe of air conditioning
generally adopts the external balance view mode to cope with the
pressure drop from the evaporator inlet to the compressor suction
port. Therefore, the quality of refrigerant copper pipe directly affects
the refrigeration effect of air conditioning.
