Abstract
A heating, ventilation, air conditioning and refrigeration system includes a diffuser comprising a plurality of diffuser elements located between a blower driving airflow through the system and a refrigeration coil used to cool the airflow prior to the distribution of the airflow to a building. Locating diffusers between the blower and the refrigeration coil reduces the extent to which the airflow carries moisture from condensate on the refrigeration coil, and can prevent circulation of air backwards through the refrigeration coil.
Claims20
A heating, ventilation, air conditioning and refrigeration (HVACR) system, comprising:
- an air handling unit comprising a blower driving an airflow,
- a refrigerant coil, located downstream of the blower with respect to the airflow,
- a plurality of diffuser elements disposed between the blower and the refrigerant coil with respect to the airflow, and
- one or more drain pans, downstream of the refrigerant coil with respect to the airflow,
- wherein the plurality of diffuser elements are arranged in at least two rows of diffuser elements, and, with respect to the refrigerant coil, each row of the at least two rows of diffuser elements is spaced apart from other rows of the at least two rows of diffuser elements.
A method for directing an airflow through an air handler of a heating, ventilation, air conditioning, and refrigeration (HVACR) system, comprising:
- driving the airflow using a blower,
- deflecting the airflow via a diffuser comprising a plurality of diffuser elements,
- cooling the airflow via a refrigerant coil after the airflow has been deflected by the diffuser, and
- capturing moisture in one or more drain pans downstream of the refrigerant coil with respect to the airflow,
- wherein the plurality of diffuser elements are arranged in at least two rows of diffuser elements, and, with respect to the refrigerant coil, each row of the at least two rows of diffuser elements is spaced apart from other rows of the at least two rows of diffuser elements.
