Is it a Heat pump or and AC only
I ran across this system in a newer building the other day and got stumped.
The equipment that I was looking at had a label that that said it was a water source heat pump.
It was in a large multi story residential building. The equipment was in a closet. There was one blower fan , one compressor, two coils (one evaporator and the other a heating coil.)
Basically the equipment used water from a boiler to heat the coil when an actuator was opened by a call for heat.
The AC used a water source and the compressor.
The refrigeration system had no reversing valve.
I was wondering if I missed something or what. I thought that a heat pump by definition did heating and cooling by the use of the refrigerant systems reversing valve.
This system looked like an AC only with another coil for heating from the boiler source.
Is this a heat Pump?
