An innovative refrigerated display cabinet is an open refrigerator designed with a PVC curtain and air curtain. This is acts as an artificial door between the cabinet and outside area. In this paper we have discussed the comparison between air curtain and PVC curtain. Due to transparency of PVC material customer can see the product and access the product. The purpose of using PVC strip curtain is to keep cabinet temperature between-2 Cto+ 6 C and food product temperature between 0 C to+ 6 Cwhere as air curtain, cabinet temperature can be obtained+ 6 C to+ 9 C and food product temperature+ 12 C to+ 22 C. Thus it has been observed that electrical energy consumption including compressor power and fan power is to be 1.63 KWh/day for air curtain and 1.12 KWh/day for PVC curtain.
