[TRNSYS-users] Abouth Typ557

[sun liang]

Hello Trnsys users:
 
I want to evaluate the energy performance and control strategies of  a ground source heat pump system. In this system, the ground heat exchangers are divided into to two subregions.  When the cooling load is less than the half of the designed cooling load, the ground heat exchangers of one subregion are uesd to providd cold water. And the ground heat exchangers of the other sunregion do not work. While in the hottest period, all the ground heat exchangers of two subregions need to work together.  So I need two models of Type557 to simulate the energy perfomance of ground heat exchangers of two subregions.  However, the Trnsys project with two modules of Type557 can not work. The error is listed as follows:
    Generated by Type     :   557
    TRNSYS Message    103 : The TRNSYS TYPE checking routine has found an inconsistency in the specified component between the input file and the information expected by the Type
    Reported information  : The maximum number of occurences of this component model in a TRNSYS input file has been exceeded.
 
I want to know how I can do to deal with this problem. I am looking forward to your reply. Thank you very much.
 
Best regards,
Cathy
