    Low pressure receiver in DX system



    Dear All,

    Please have a look at the attached drawing.

    Any body used or seen this system?

    The low pressure receiver acts as a flash gas removal tool (it seems).

    Any practical problems using this system ?

    Appreciate any input.

    Cheers,
    LANA

    Thanks for the reply.

    That's why I raised the question.

    I have seen this on a mini water chiller catalouge (not seen it on action).

    Any more inputs will be great.

    Re: Low pressure receiver in DX system

    I have seen this type of low pressure receiver use at new York screw chillers (MODEL YCIV) mention flash tank by controlling with two electronic expansion valve. So the main purpose of this to remove the flash gas, same like economizer using for centrifugal chillers. As per your catalogue, there is not low side expansion device and why use for this mini chiller.

    This is not complete drawing. Suction from LPR should be connected to the compressor. LPR should be insulated. Liquid pump should supply liquid to the evaporator.

    Re: Low pressure receiver in DX system

    Would that be a DX system with no expansion device between the receiver and the evaporator ?

    Wouldn't it be more like a flooded evaporator system ?

    Re: Low pressure receiver in DX system

    Thanks guys for the inputs.

    The drawing I saw is like the drawing I sent. All the replies seem correct that's why I am confused. We have this in liquid circulation system with liquid pump BUT on a DX??? Something is wrong I think!!!

    Thanks again

    It is not problem to use liquid pump for DX coil. However, when you throttle refrigerant to LPR flash gas will be created If you don't have suction line, how this gas can be removed.
