  • Page 20: Unit Operation

    Unit Operation Air-to-Air Cooling Products (Air Conditioners) The cooling mode operates similar to a refrigerator, removing heat from inside the conditioned space and rejecting it outside of the space being controlled. There are three main parts of the system: 1. The evaporator (indoor) coil where cold refrigerant absorbs heat from the air, which circulates from the conditioned space through the machine and is returned to the space at a lower temperature and with some of the humidity (moisture) removed.

  • Page 21: Water-To-Air Cooling And Heating Products (Geothermal Heat Pumps)

    terminates, the reversing valve will shift back to heating mode and the outdoor fan will restart. There is typically a large puff of steam emitted as the fan restarts. When the heat pump shifts from cool to heating mode, from heating to cooling mode and especially during defrost cycles, there will be a pressure transfer sound heard as the reversing valve redirects the flow of refrigerant.

  • Page 22: Dehumidification And Ventilation Operation

    Ventilation Options (Air-to-Air or Water-to-Air Systems) All Bard systems are available with factory-installed vent options. Most units can have ventilation field installed after unit installation.
