Freezer Wrapped Condenser

The wrapped condenser incorporates a precooler condenser in series (through an oil cooler) with the main condenser. The condenser, made of 1/4 in. steel tubing, is clamped to the cabinet wrapper. Thermal mastic is applied to each pass for maximum heat dissipation.

A wrapped condenser depends on natural convection of room air for dissipation of heat. Restricted air circulation around the cabinet will cause high operating temperatures and reduced capacity. The wrapped condenser reduces the possibility of moisture condensing on the cabinet shell during extremely humid weather. It also eliminates the need for periodic cleaning of the condenser. Figure 13-5 shows the condenser layout on an upright freezer.
