Auxiliary heat exchanger coil for outdoor side-discharge units

A side-discharge outdoor unit of a climate control system comprising:

• an enclosure defining an interior space and an exterior boundary of the side-discharge outdoor unit;
• a compressor located within the enclosure and configured to circulate a refrigerant fluid within a refrigerant fluid circuit of the climate control system;
• an L-shaped primary heat exchanger located within the enclosure and coupled to the refrigerant fluid circuit, the L-shaped primary heat exchanger being configured to transfer thermal energy between the refrigerant fluid circuit and an external environment;
• a plate shaped auxiliary heat exchanger located within the enclosure and coupled to the refrigerant fluid circuit, the plate shaped auxiliary heat exchanger being configured to transfer thermal energy between the refrigerant fluid circuit and the external environment;
• an outdoor fan located within the enclosure and configured to provide an airflow from the external environment to contact at least the L-shaped primary heat exchanger and the plate shaped auxiliary heat exchanger;
• and
• a switch over valve (SOV) coupled to the refrigerant fluid circuit configured to adjust a direction of flow of the refrigerant fluid between the primary L-shaped heat exchanger and an indoor heat exchanger of the climate control system,
• wherein the enclosure includes:
• a heat exchanger guard defining the exterior boundary for a first section, the first section located along one or more sides of the enclosure, wherein the L-shaped primary heat exchanger is disposed within the interior space along a portion of the first section proximate the heat exchanger guard,
• a cover plate defining the exterior boundary for a second section and including a plurality of openings, the second section located on a top of the enclosure, wherein the plate shaped auxiliary heat exchanger is disposed within the interior space along a portion of the second section proximate the cover plate,
• a side panel section including an airflow opening and defining the exterior boundary of a third section, the third section adjacent the first section and located along one or more sides of the enclosure, and the airflow opening configured to allow an airflow between the interior space and the external environment,
• wherein the outdoor fan is aligned axially with the airflow opening, and
• wherein the second section spans between the first section and the third section,
• wherein the L-shaped primary heat exchanger and the plate shaped auxiliary heat exchanger are fluidly arranged in series within the refrigerant fluid circuit, and
• wherein the auxiliary heat exchanger is fluidly coupled to the refrigerant fluid circuit between a discharge port of the compressor and the switch over valve such that both an inlet and an outlet to the auxiliary heat exchanger are coupled to the refrigerant fluid circuit between the discharge port of the compressor and the switch over valve.
