Cooling and freezing at once smart system

Managing daily fluctuation of power prices

Van Kempen Koudetechniek provided the refrigeration and freezer systems for Frost Service's production and distribution site in Venlo.

Main contractor Wijnen Bouw involved Van Kempen in the project. Account Manager Marcel Denecke: "We delivered and installed a CO2-DX system for cooling and freezing here. This system is designed to provide four large freezer cells with cold to temperatures between -18 and -22°C. In addition, they cool the shipping area and production area between 5 and 10°C." 

Heat Recovery

Van Kempen's system provides cooling with low-noise fans. In addition, careful attention has been paid to preventing drafts, so that the environment is pleasant for the people working there. The system also uses heat recovery to heat the underfloor heating of the freezer cells. This prevents the formation of ice under the floor due to groundwater freezing. Indeed, if a layer of ice forms under the floor, the floor could crack.

Smart system

The plant is controlled by Van Kempen Koudetechniek's VK Dynamics control system. This is designed to keep energy consumption as low as possible. It is even available with control based on the daily fluctuation in electricity prices (EPEX). Denecke: "Every day at 1 p.m. it is known what the electricity prices will be for each half hour the following day. The installation can anticipate this by buffering extra cold in the product when the power price is low. If the power price rises again, the freezer switches
automatically off."

Van Kempen is pleased with how the project went. "In good consultation with Frost Service, we created this design together. Also, the facilities on the construction site were good and it was nice working with the contractor."
