Multifluid heat pump system

Patent ·
OSTI ID:6240694

A method is described of heating or cooling an indoor space and/or heating or cooling a stored liquid comprising the steps of: operating a heat pump to transfer heat between and among an indoor heat exchange coil located within the conditioned space, outdoor heat exchange coil located outside of the conditioned space and a desuperheat exchange means; transferring heat between the indoor coil and the conditioned space by passing ambient air over the indoor coil; storing heat transferred between the indoor coil of a multifluid heat exchange means and/or the desuperheat exchange means and the outdoor coil by circulating a stored liquid between a heat storage facility and the second heat exchange coil of the multifluid heat exchange means located in thermal contact with the indoor coil, and/or selectively circulated through the liquid coil of the desuperheat exchange means; or storing ''cool'' transferred between the indoor coil and the outdoor coil by circulating a stored liquid between a cool storage facility and the second heat exchange coil of the multifluid heat exchange means located in thermal contact with the indoor refrigerant coil of the multifluid heat exchange means; and transferring stored heat/cool between the heat/cool storage facility and the conditioned space by circulating the stored liquid between the heat/cool storage facility and the second heat exchange coil of the multifluid heat exchanger and passing ambient air over the second heat exchange coil.
