Dear Trnsys users,I have been simulating the solar hot water system with a variable flow rate which mainly consists of type 534 solar collector(TESS), type 60 storage tank with one internal heat exchanger and four pipes of type 31. Generally, in type 534, if I set the 'pump control consumption' to 1,it will means that we could keep the collector outlet at the specified condition (eg, the outlet temperature of the collector is 55°C) by varying the flow rate. Unfortunately, I tried running many times but it always indicates these error messages that the UAHx of storage could not converge during one time step and the following time step it will use the value of the last iteration. I have attached fiche tpf .
I would like to know what the problem is about this system. I would appreciate any help Thanks in advance yu.Bai Doctorante LOCIE-groupe Développement Energétique Durable ESIGEC-Université de Savoie Campus Scientifique Savoie Technolac 73376- Le Bourget du Lac Cedex (France) Tel: 04 79 26 44 34 email: yu.bai@etu.univ-savoie.fr
