CBA Eko Market

Daikin systems provide ’invisible’ climate and temperature control for city supermarket


CBA sought a refrigeration and air conditioning solution using ‘green’ technologies for a new 580 square metre food retail store in central Sofia. Daikin’s ZEAS & Conveni-Pack systems, with third party freezer and cold store equipment, offered an integrated approach to meet both their sustainable refrigeration and heating and cooling needs.

The Sofia Eko Market is part of a mixed-use development combining residential and retail use. Along with energy efficiency, noise control and appearance were therefore essential factors in the choice of HVAC-R equipment.

The outdoor units were sited unobtrusively behind screens next to the residential building entrance, which avoided costly reconstruction work. Low noise levels and night settings for reduced fan speeds minimises disturbance.

Plug-in cabinet solutions from AHT (also part of the Daikin group), linked to the ZEAS system, deliver the heavy-duty capacity required for display, freezer and cold storage areas. By reducing the capacity and number of outdoor units required, the AHT units also helped minimise equipment and installation costs for CBA.

A key requirement was to provide air conditioning for a small office and rest area. A single indoor unit connected via a duct with multiple zoning allows separate temperature control of each area via a wiredin control. Once the required set point is reached, any excess heat is recovered and diverted to the 430 square metre shop floor or used to reduce capacity requirements, minimising running costs.
