[Equest-users] Air source heat pumps - which equest systems

[Paul Diglio]

Chris:

With over 35 years in the HVAC installation & maintenance feilds I have never 
seen a system that incorporates a heat pump and hydronic cooling.  Defeats the 
purpose of a heat pump.

One normally associates air source heat pumps with DX cooled systems.  But I 
notice that you can select HEAT-SOURCE = HEAT-PUMP for systems I would normally 
consider hydronic. For example a VAVS system which only allows hydronic cooling 
allows the option of Heat Pump for heating.  Would this be a common practice in 
construction?

It is more hypothetical than actually wanting/needing to model this 
configuration.
