BP12 - Improve refrigeration

Company name: VINH NGUYEN PRIVATE ENTERPRISE
Address: 709, Dong An Hamlet, Tan Hiep Town, Tan Hiep District, Kien Giang Province
Project Summary: An investment project in improving the refrigeration system, with many solutions. The project goal is to reduce energy costs and emission of greenhouse gases.
Year of implementation: 2018

Status before implementation

Vinh Nguyen Private Enterprise is specialized in ice production with the following main products: Ice blocks, ice cubes. The factory has two (2) systems:

  • Ice block production: 2 single-stage reciprocating compressors, total installed capacity of 199 kW.
  • Ice cube production: 2 single-stage reciprocating compressors, total installed capacity of 70 kW.

These refrigeration compressors have a long service life, the average COP is about 1.6.

 Refrigeration compressor            Ice block storage

In order to save energy, the plant expected to replace 4 existing reciprocating refrigeration compressors with 4 high-efficient reciprocating refrigeration compressors.

Result

The plant has reduced by 25.6% of the total electricity consumption for the ice cube and ice block production system compared to the past. Emission is reduced by 202 tons of CO2/ year
