The disclosed technology includes an air system including a first interlaced microchannel heat exchanger and a second interlaced microchannel heat exchanger. The air system can include a plurality of fluidly separated refrigerant circuits, and each of the refrigerant circuits can be configured to flow through the first interlaced microchannel heat exchanger and the second interlaced microchannel heat exchanger. The first interlaced microchannel heat exchanger can be located indoors, and the second interlaced microchannel heat exchanger can be located outdoors. Each of the refrigerant circuits can include its own compressor and expansion valve.

Interlaced microchannel heat exchanger systems and methods thereto

Heat exchanger slide rails

Heat exchanger tube with fins

A heat exchanger having a first heat exchanger tube and a second heat exchanger tube is disclosed. The first heat exchanger tube can have a first leg, a second leg, and a bend section, and the bend section of the first heat exchanger tube can include three or more bends, each of the three or more bends having a corresponding bend angle that is less than or equal to approximately 90 degrees. The second heat exchanger tube can have a first leg, a second leg, and a bend section, and the bend section of the second heat exchanger tube can include three or more bends, each of the three or more bends having a corresponding bend angle that is less than or equal to approximately 90 degrees.

Heat exchangers providing low pressure drop

A heat exchange tube for an HVAC system can include at least one reduced diameter section with an integral flattened ridge. The flow of combustion gases through the heat exchanger tubes may be partially constricted inside the reduced diameter sections. When installed in an HVAC system the integral flattened ridges may be angled to intercept the flow of air outside the heat exchanger tubes.
