Re: [TRNSYS-users] type 107



Ana,
I think that the hot side outlet temperature of your heat exchanger should be connected to the chilled water inlet temperature of Type107, not to the cooling water inlet temperature. There are two water streams that go through the absorption chiller. The chilled water stream comes back from your load and is cooled down to the set point temperature. The cooling water stream enters the absorption chiller and is heated up with the energy rejected from the chilled water stream.

One other note: if you are using Type5 as a water to air heat exchanger, particularly one that cools air, don't forget to put a Type33 (psychrometrics) on the outlet of Type5. As inputs to Type33, use the dry bulb temperature coming from the Type5 outlet and the absolute humidity ratio of the air at the inlet to Type5. Take the relative humidity calculated by Type33 and give it back to Type56 as the relative humidity of the supply air.

Kind regards,
 david

Dear users,
I am using Trnsys 16. I am connecting the Type 107 (absorption chiller) to the
Type 56 (multizone building) for obtaining the total energy consumed for
cooling. I connected an air to water heat exchanger (Type 5) between Type 107
and Type 56. My problem is in the inputs of the Type 107. I did the next:
Hot side outlet temperature (Type 5) ->cooling water inlet temperature (Type
107)
  Chilled water temperature (Type 107)->cold side inlet temp. (Type 5)
  Cold side outlet (Type 5) ->T_Cool_ON (input) (Type 56)
  Air temperature of zone (Type 56) ->hot side inlet temp. (Type 5)
 But I don't know what I do with the input "Chilled water inlet temperature"
(Type 107).
  Can you help me?
Thank you
Ana
