Abstract
A refrigerated display case reduces the temperature of refrigerated items in the front of the case and achieves a tighter temperature range within the case. Air drawn from a cooler is further cooled by a coil. Some of the cold air is discharged along the front of the case as an air curtain is and drawn by fans back into the cooler. The remaining cold air is directed to a duct in the rear of the case. Openings in the duct allow air to flow across the refrigerated items towards the front of the case, further reducing the temperature of the refrigerated items in the front of the case. To prevent refrigerated items in the rear of the case from freezing, air entering the duct is warmed with air that bypasses the coil.
Claims14
A refrigerated case comprising:
- a first flow path of cool air directed along a front of said case;
- a second flow path of cool air directed along a rear of said case;
- and
- at least one diverging path of cool air diverging from said second flow of cool air and flowing towards said first flow path.
A refrigerated case comprising:
- a first flow path of cool air directed along a front of said case;
- a second flow path of cool air directed along a rear of said case;
- at least one diverging path of cool air diverging from said second flow of cool air and flowing towards said first flow path;
- a cooler adjacent to said rear of said case;
- a fan at a top of said rear of said case to draw cool air from said cooler and into said case;
- a cooling coil that further cools said air drawn into said case from said cooler by said fan, and said air cooled by said cooling coil is directed along said first flow path and said second flow path.
A method of refrigerating a case comprising the steps of:
- directing a first flow path of cool air along a front of said case;
- directing a second flow path of cool air along a rear of said case;
- and
- directing at least one diverging path of cool air from said second flow of cool air and towards said first flow path.
