Re: [TRNSYS-users] Type 534 with no HX, vertical storage tank

[David BRADLEY <d.bradley@tess-inc.com>]

Vanentin,
  Type534 is ideal for that situation; I've used it many times with exactly that configuration. I would refer you to the Type534 documentation (..\TrnsysXX\Tess Models\Documentation\Storage Tank Library\Type534.pdf) to learn about how the component treats internal mixing.
Kind regards,
 David

Hello to all,

 

I am trying to simulate a solar system (solar panels à external HX à vertical storage tank) where the storage tank has 2 inlets/outlets :

-          one inlet/outlet from/to the external HX,

-          the other inlet/outlet concerns the supply/draw of this tank with cold/hot water.    

 -------------------

                                                               |                             |--> Hot water

                                                               |                             |

|                             |

                                                               |                             |

        From the external HX    --> |    No internal  |

|             HX          |

                                                               |                             |

|                             |

            To the external HX     <--  |                             |

                                                               |                             |<-- Cold water

                                                                -------------------

 

My questions :

-          Anyone of you simulated a similar installation ?,

-          Is it possible to use Type 534 with 0 HX ? The tank is a constant volume one,

-          How the Type 534 treats the mixing in the tank ? ,

-          Type 534 can deliver acceptable results in this configuration or another type will be more suitable ?   

-          What value of the mixing flow inside the tank will be adequate in this configuration ?

 

Thank you in advance for your answers,

 

Best regards,
