Heat Pumps With R32 Refrigerant

proposterous | Posted in General Questions on

It seems that there are still no residential heat pumps using R32 refrigerant available in the USA. Does anyone have information on if/when such units (like the LG Therma V) may become available here?

    I’m going to give your question a bump. In the meantime, read through this Q&A thread. Another reader asked the same question back in May.

    This from Daikin website

    “As the only manufacturer that develops and manufactures both air conditioners and refrigerants, Daikin launched the world's first residential-use air conditioner
    using R-32.”

    Most manufactures will not willingly do business with their competitors if at all possible.
    My guess is you will see it in Daikin units but nowhere else unless it is the last legal option open to other manufactures or the patent expires.

    It appears as though its Honeywell that is blocking the adoption of R32 into code!

    We have an active HVAC contractor that has been talking with engineers in the industry - they are saying it will be an industry wide transition starting this summer. The R32 has reduced efficiency and as such it is expected that AHRI is going to start re-rating the equipment as the rollout of R32 occurs. Here in the PNW we have some high bars to reach for code and it is expected to throw a big wrench meeting basic code requirements. We've reached out to others in the industry to verify and learn more...

      R32 has reduced efficiency? Everything I've read up on claims increased efficiency?
