An HVAC heat exchanger with an array of tubes including one or more dead tubes is provided. In one embodiment, the heat exchanger is a microchannel heat exchanger operable to exchange heat with air in an HVAC system via refrigerant passing through the microchannel heat exchanger. The microchannel heat exchanger includes an array of flat tubes arranged between a first manifold and a second manifold. The array of flat tubes includes multiple tubes coupled in fluid communication with the first manifold and the second manifold to convey refrigerant between the first manifold and the second manifold through microchannels of the multiple tubes. The array of flat tubes also includes one or more dead tubes that do not convey refrigerant between the first manifold and the second manifold. Additional systems, devices, and methods are also disclosed.

Heat exchanger assembly and method for HVAC system

An HVAC system for use with a first refrigerant and a second refrigerant. The HVAC system may include a first refrigerant circuit for use with the first refrigerant, a second refrigerant circuit for use with the second refrigerant, and a heat exchanger. The first refrigerant circuit and the second refrigerant circuit may each include may include a compressor, an expansion device, and an evaporator. The compressor may include a first upper section, a first lower section, a second upper section in fluid communication with the first lower section, and a second lower section in fluid communication with the first upper section. The first upper section, the first lower section, the second upper section, and the second lower section may be arranged such that the first refrigerant and the second refrigerant both flow through a majority of a face area of condenser while remaining in two different circuits.
