    A question about suction line heat exchanger

    Hello all,

    I have a question about suction line heat exchanger. I learned from some papers that in R134a, R404A and R600 systems, suction line heat exchanger is very helpful to increase energy efficiency; but it does not work well in R22 systems. Could anyone explain why this happens?

    In my opinion, as suction line heat exchanger always increases system super heat and reduce the refrigerant mass flow, adding suction line heat exchanger always reduce system cooling capacity. Is it correct?

    How about R410a? Does the suction line heat exchanger help to indrease the energy efficiency?

    Thanks
