    VRF refrigerant leak



    I was recently told by a technical department that an ac system that is short of refrigerant would be more apparent in HEAT mode rather than COOL mode; based on air on/off temperatures on indoor units.

    I always understood that HEAT mode used heat of compression as well as phase-change to generate really efficient heating that demanded less power input. And in COOL mode you relied only on refrigerant phase-change for cooling effect.

    Can someone please explain this to me?
    Thanks

    Explain why a lack of refrigerant is more apparent in HEAT mode rather than COOL mode?
