    I had problems with Frigidaire Mc on furnaces. They have a static problem. I no longer use nordyne. York uses Mc also on some of there products. I just looked into Rheem that my distributor is picking up and they had an aluminum tube/fin coil so I'm not sure if they are switching to that or if they still produce the mc. Looks like nice equipment but I'm not sure of there reputation.

    Just looked that up. I've not seen one. Are they just on resi, high efficiency heatpumps?

    No, they're on a lot of equipment. They're replacing accumulators as they're smaller & more efficient since we have TXVS on most equipment. They act like a receiver. With a TXV the refrigerant backs up, fills the compensator & there's no need for an accumulator.

    Yeah I guess I'll have to read more about them. It seems to me that their application would be for heat pumps with a varying load between heat and cool and where does the extra refrigerant go if it's a mismatched system. The Emerson site would not load up for me on my phone . I wonder if anyone has a link to a compensator interior breakdown and description of its intended use.

    From what I understand about micro channel systems, you can not mix & match. Both indoor & outdoor needs to be micro channel or both tube coils.

    Someone please correct me if I am wrong. Rather be wrong here than on a service call trying to figure out why it is not working.
    Can someone please explain to me -
    Why is there never enough time to do it right the first time, but plenty of time to do it twice?

    There are quite a few that are mix matched per say. Usually see more systems with micro channel condenser and tube evaps. Just lately been setting pack units where both coils are micro channel. Only done a few splits where both were micro channel.

    I don't think that is the case at all unless it is specific to a brand you work on. York and Nordyne it is not.

    In the commercial work I do, lot's of micro channel condensers, and no micro channel evaps.

    Over the years evaporators have come a long way. 26 fins per inch, thinner wall tubing & the evaporator coils tend to use rifled tubing to spin the refrigerant evenly across the surface area.

    I had similar problems with water source heat pumps that were 410A. 60-70% came 10-12oz over charged. (Mcquay/Daiken were the WORST)

    Charge Compensators
    The ACC charge compensator increases system efficiency by storing extra refrigerant in the heating mode then returns refrigerant back into circulation in the cooling mode.

    Designed to work in heat pump and micro-channel applications. The heat pump ones look like this, the suction line cools the refrigerant & keeps it as a liquid. Acts like a receiver for liquid refrigerant.


    The ones for micro-channel applications look like a 162-S filter drier with only one inlet. You tap into the liquid line with a 3/8"×1/4"×3/8" T & run a 1/4" line to the compensator which is mounted on the sheet metal using a "U" strap. During low load the compensator acts like a receiver, holding liquid refrigerant & keeps the unit from tripping on head pressure.
