Good morning, I am trying to simulate a water-water heat pump (Type 927) which is able to provide space heating/cooling, domestic hot water heating, as well as cooling a tank for dehumidification. The problem I have is that whenever the hot water is required, the pump goes on and the temperature of the tank increases up to 3000 degrees. After it is slowly decreasing to an average temperature of 15 degrees.
I have tried to follow the ZNE_House model provided with the software but the behaviour in this case is the same. The temperature of the tank jumps to thousands of degrees. Thank you very much and I am looking forward to hearing from you. Luminita Dumitrascu |
