First Daikin Zeas refrigeration system installed

First Daikin Zeas refrigeration system from Climate Center installed at SeeWoo Foods cash and carry in Greenwich

The system, installed by Stonegrove Refrigeration Services Ltd, replaces an aging R22 system running on reciprocating compressors that had become unreliable and inefficient.

The SeeWoo Foods’ system consists of three low temperature units and one high temperature unit, serving refrigerated food display cases in the store.

In addition to its efficiency and reliability, the Daikin Zeas units were chosen for their compactness and small footprint due to the restricted space at the rear of the SeeWoo Foods’ Greenwich site.

The refrigeration plant switchover had to be carried out according to a tight timetable in order to minimise disruption to store trading. The critical switchover took place on sections of cases between 7.00pm on a Monday night and store trading as normal at 9.00am the following Thursday morning over a four week period.

Ray Cashmore, managing director of Stonegrove Refrigeration Services Ltd, said: “The Zeas is a superb product, and from the contractor’s point of view a joy to install and commission. Because of the compactness of the system it enabled the client to convert the previous plant room to productive use, and it is now being used as a cold room for fish.”

Based on DC inverter-driven Scroll compressors, they deliver a Coefficient of Performance (COP) of up to 3.0, a level of efficiency not obtainable with traditional non-inverter technology.

Zeas units are based on the high capacity refrigerant R410A, making systems compact with a small foot-print and enabling installation of large cooling capacities in areas with restricted space, as at the SeeWoo site.

Inverter control gives the twin benefit of reduced stop/start cycles, prolonging equipment life, and precise matching of cooling capacity to load, ensuring low running costs.

Zeas units are available for use in medium temperature (12.2 to 37kW capacities) and low temperature applications (5.4 to 15.1kW).
