Hello,
Does anybody has idea how to model gas engine heat pump (GHP) in eQUEST software? There are two types of this GHP as below:
- Air to water GHP unit.?
- VRF GHP.
Please refer to the below link for more details about these GHPs. Thanking in advance for your help.

Hello Ahmad:
I'm not clear about your system. A quick look at the EQUEST manual does not show such a system in the index.
However, a general google search of such systems shows lots of options, for example, a gas fired furnace combined with a heat pump? Or possibly a nat gas fired engine driving a heat pump compressor.
The first system is easy to model. The second would be a challenge.

Hi Ahmad, Jeff,
I haven?t used it before, but it does look like you can use the GAS-HEAT-PUMP code-word as the HEAT-SOURCE for DX units to model a gas-engine-driven compressor (see below).

In the User Guide Volume 2 (dictionary), the Air-to-Air Heat Pump section should have more information about the associated keywords for the system:
