You could consider using PTHP/PTAC (using electric for heating coil) for your small single zone. It is a single zone equ

2017-06-08 20:45:06 -0600 marked best answer Integrated Heat Pump

I have a system that comprises 4 air-sourced heat pumps for both space heating and cooling. I saw the new integrated heat pump coil system can model a single air-sourced heat pump so it cannot provide both heating and cooling simultaneously.

Is it possible to connect the integrated heat pumps in parallel so that the plant can supply both hot water and chilled water?

Or must I stay with 4 air-cooled chiller + 4 Coil:WaterHeating:AirToWaterHeatPump in order to achieve that?

2017-02-23 20:17:21 -0600 commented answer Two chilled water loop with different temperature

Thanks. As my heat pumps are connected to the same condenser loop and hot water loop but to different chilled water loops, is it still possible to set up 2 central heat pump system and connect them as designed?

2017-02-20 01:46:25 -0600 asked a question Two chilled water loop with different temperature

Hi, I have a building that has 2 chilled water loop with different loop temperature. Each is cooled by a water-to-water heat pump and providing chilled water to different equipment. Is it possible to have 2 separate chilled water loop with water-to-water heat pumps rejecting heat to the same hot water loop in EnergyPlus?

2016-09-19 01:12:29 -0600 commented answer Exhaust Heat Recovery

Thanks for your advise! I think I will explore the option of using EMS to modify the district heating loop input depending on the energy recovered from the exhaust air.

2016-09-13 00:03:10 -0600 asked a question Exhaust Heat Recovery

Hi all,

I am trying to model a system which has heat recovery coil designed at all exhaust air stream in E+. I can only see unitary system has the capability to add heat recovery coils at exhaust but my systems are mostly VAV distribution system. Any suggestion on how to model it?
