A refrigerated merchandiser includes a case defining a product display area and an air passage at least partially surrounding the product display area. The air passage directs refrigerated air to the product display area. The case also defines an air chamber separate from the air passage and in fluid communication between the air passage and the product display area. The merchandiser also includes a fan operable to draw the refrigerated air from the air passage and pressurize the refrigerated air within the air chamber to facilitate distribution of the refrigerated air from the air chamber and into the product display area.

I claim: 1. A refrigerated merchandiser, comprising: a case defining a product display area; an air passage at least partially surrounding the product display area, the air passage including a cooling passage directing refrigerated air to the product display area; an air chamber separate from the cooling passage and in fluid communication between the cooling passage and the product display area; a fan operable to draw the refrigerated air from the cooling passage and pressurize the refrigerated air within the air chamber to facilitate distribution of the refrigerated air from the air chamber and into product display area; and a plurality of louvers positioned downstream of the fan to guide the refrigerated air into the air chamber. 2. The refrigerated merchandiser of claim 1, wherein the fan is positioned in one of the cooling passage and the air chamber. 3. The refrigerated merchandiser of claim 1, further comprising a first wall separating the cooling passage from the air chamber, the first wall having an aperture fluidly connecting the cooling passage and the air chamber. 4. The refrigerated merchandiser of claim 3, further comprising a second wall spaced from the first wall, the second wall defining in combination with the first wall the air chamber. 5. The refrigerated merchandiser of claim 4, further comprising a plurality of apertures in the second wall fluidly connecting the air chamber and the product display area. 6. The refrigerated merchandiser of claim 1, wherein the refrigerated air is distributed to the product display area from the air chamber between about 200 feet/minute and about 700 feet/minute. 7. The refrigerated merchandiser of claim 1, wherein the cooling passage includes a substantially vertical portion, and wherein the fan draws the refrigerated air from the substantially vertical portion of the cooling passage. 8. The refrigerated merchandiser of claim 1, wherein the refrigerated air in the air chamber is pressurized to a static pressure of at least about 0.005 in H2O. 9. The refrigerated merchandiser of claim 1, further comprising a controller electrically connected with the fan, the controller operable to deactivate the fan during defrost mode of the merchandiser. 10. The refrigerated merchandiser of claim 1, wherein the pressurized refrigerated air in the air chamber provides a positive air flow over products positioned in the product display area to substantially sublimate frost accumulated on the products. 11. A refrigerated merchandiser, comprising: a case defining a product display area; a cooling passage at least partially defined in a rear portion of the case to direct refrigerated air to the product display area, the cooling passage defined in part by a first wall having an aperture therein and including a substantially vertical portion; a second wall spaced from the first wall, the first and second walls defining in part an air chamber in fluid communication with the product display area through a plurality of apertures in the second wall; and a fan operable to move the refrigerated air from the substantially vertical portion and through the aperture in the first wall to pressurize the refrigerated air within the air chamber to facilitate distribution of the refrigerated air from the air chamber and into the product display area through the apertures in the second wall. 12. The refrigerated merchandiser of claim 11, wherein the fan is positioned in one of the cooling passage and the air chamber. 13. The refrigerated merchandiser of claim 11, wherein the refrigerated air is distributed to the product display area from the air chamber between about 200 feet/minute and about 700 feet/minute. 14. The refrigerated merchandiser of claim 11, further comprising a plurality of louvers positioned downstream of the fan to guide the refrigerated air into the air chamber. 15. The refrigerated merchandiser of claim 11, wherein the refrigerated air in the air chamber is pressurized to a static pressure of at least about 0.005 in H2O. 16. The refrigerated merchandiser of claim 11, further comprising a controller electrically connected with the fan, the controller operable to deactivate the fan during defrost mode of the merchandiser. 17. The refrigerated merchandiser of claim 11, wherein the pressurized refrigerated air in the air chamber provides a positive air flow over products positioned in the product display area to substantially sublimate frost accumulated on the products. 18. A refrigerated merchandiser, comprising: a case defining a product display area and a cooling passage having a substantially vertical portion in a rear portion of the case separate from the product display area; an evaporator operable to refrigerate airflow passing through the evaporator and into the substantially vertical portion; a first fan operable to generate the airflow through the evaporator and into the substantially vertical portion; a second fan positioned downstream of the evaporator to draw the refrigerated airflow from the substantially vertical portion; and an air distribution chamber adjacent to and in fluid communication with the substantially vertical portion to receive the refrigerated airflow drawn from the substantially vertical portion by the second fan, the air distribution chamber comprising a plurality of outlet openings fluidly communicating the air distribution chamber with the product display area to substantially distribute the refrigerated airflow to the product display area. 19. The refrigerated merchandiser of claim 18, wherein the second fan is positioned in one of the cooling passage and the air distribution chamber. 20. The refrigerated merchandiser of claim 18, further comprising a first wall separating the cooling passage from the air distribution chamber, the first wall having an aperture fluidly connecting the cooling passage and the air distribution chamber. 21. The refrigerated merchandiser of claim 20, further comprising a second wall spaced from the first wall, the second wall defining in combination with the first wall the air distribution chamber. 22. The refrigerated merchandiser of claim 21, wherein the outlet openings are located in the second wall. 23. The refrigerated merchandiser of claim 18, wherein the refrigerated airflow is distributed to the product display area from the air distribution chamber between about 200 feet/minute and about 700 feet/minute. 24. The refrigerated merchandiser of claim 18, further comprising a plurality of louvers positioned downstream of the second fan to guide the refrigerated air into the air distribution chamber. 25. The refrigerated merchandiser of claim 18, wherein the refrigerated airflow in the air distribution chamber is pressurized to a static pressure of at least about 0.005 in H2O. 26. The refrigerated merchandiser of claim 18, further comprising a controller electrically connected with the second fan, the controller operable to deactivate the second fan during defrost mode of the merchandiser. 27. The refrigerated merchandiser of claim 20, wherein the pressurized refrigerated airflow in the air distribution chamber provides a positive air flow over products positioned in the product display area to substantially sublimate frost accumulated on the products.
