Commercial refrigeration unit and microchannel evaporator for commercial refrigeration unit

A commercial refrigeration unit, comprising:

• a display zone defining a region adapted for display of one or more products;
• an airflow device adapted to circulate air along in an airflow zone of the commercial refrigeration unit;
• and
• a microchannel evaporator disposed in the airflow zone and adapted to exchange heat with the circulating air in the airflow zone, the microchannel evaporator comprising:
• a plurality of flow circuits, each flow circuit comprising at least one tube adapted to allow a flow of refrigerant fluid therethrough, wherein each flow circuit further comprises at least one inlet, and at least one outlet;
• a plurality of fin elements adapted to removably coupled with the plurality of flow circuits, each fin element comprising at least one fin, wherein, responsive to coupling of the plurality of fin elements with the plurality of flow circuits, the at least one fin of each of the plurality of fin elements is arranged in between at least some of the tubes of the plurality of flow circuits,
• wherein the plurality of flow circuits is arranged such that an air passage is formed between at least some of the tubes to allow passage of the circulating air therethrough,
• wherein the plurality of flow circuits is arranged such that the corresponding tubes of the plurality of flow circuits are in any or a combination of parallel and serpentine configurations, and
• wherein the plurality of fin elements is arranged such that a condensation passage is formed between at least some of the fin elements to allow passage of condensate formed in the microchannel evaporator, and
• wherein the microchannel evaporator is oriented in the airflow zone, such that the condensation passage allows the passage of condensate along a direction of flow of circulating air towards a first surface of the microchannel evaporator that is positioned downstream relative to the direction of flow of circulating air.
