US 2002/0162346 A1 · Medium temperature refrigerated merchandiser

Abstract

A refrigerated merchandiser (100) includes an upright, open-front, insulated cabinet (110) defining a product display area (125) connected in airflow communication with a compartment (120) via an air circulation circuit (122, 114, 116). A high pressure drop evaporator (40) and a plurality of closely spaced fans (70) are disposed within compartment (120). The evaporator (40) is provided with a relatively high fin density heat exchanger coil providing a relatively high air side pressure drop through the evaporator. The increased flow resistance through the evaporator coupled with the plurality of closely spaced fans results in a substantially uniform evaporator outlet temperature profile across the length of the evaporator.

Dependent claims

A refrigerated merchandiser system comprising:

an insulated cabinet defining a product display area and having a compartment separate from product display area;
an air circulation circuit connecting said product display area and said compartment in air flow communication;
a relatively high pressure drop evaporator disposed within said compartment, said evaporator having a fin and tube heat exchanger having a fin density in the range of 6 fins per inch to 15 fins per inch, said fins having an enhanced heat transfer configuration;
and
a plurality of air circulating fans disposed within said compartment in cooperative relationship with said evaporator.
