Polycore honeycomb panel has excellent compressive strength act as air curtain in refrigerated display cases.
Polycore Technology provide air curtain has excellent properties:
1. Core uniformality, inside smoothness, cleanness, surface level off.
2. PP raw material is safe for using as airfcurtain in showcase.
3. Lower shrink rate when temperature drop to -30 degree. This is very important for durable life of air curtain and provide installation safety for showcase manufacturer and supermarket operator.
The air curtain characteristic plays a very important role on the performance of vertical and stand refrigerated display case. The transient temperature of the display case shelves was measured for studying the temperature variation and distribution in the vertical display case by changing the number and the velocity of air curtain. The result shows that it is necessary to keep three air curtains in a vertical open low temperature display case and the performance of the display case can be improved by selecting reasonable air curtain velocities.
