yes. I am working in Shanghai. I will be very glad to discuss with you about the problems in E+ simulation. you can contact me by e-mail or phone. my mobile phone is 13301856961.

主题： [EnergyPlus_Support] Re: air to water heat pump

 

Indeed, I had the same concern recently. Use the heat pump water
heater component along with water tank:mixed (to connect condenser to
water loop, DX:Coil:heatpumpwaterheater and a Fan:OnOff. That makes 4
object to use.

Still, there is a limitation for that: If the air entering the
evaporator is below 5?, the heat pump stops. In China, they do use
these heat pumps for lower temperature even if COP is bad, that is a
problem I could not avoid and if anyone has an idea, he/she is
welcome to propose!

Mr Yiqun Pan, you are working in Shanghai? I am in Beijing and I
would be glad to discuss with you about models of EPlus that we
should work on according to simulation use in China

Best Regards
Aymeric
