HEATING A GERMAN INDUSTRY HALL WITH A HFC CHILLER

HEATING A GERMAN INDUSTRY HALL WITH A HFC CHILLER

27.06.2014

A HFC based VRV (Variable refrigerant volume) chiller, working as heat pump,  has been installed to provide underfloor heating for a new industrial hall at a leading German manufacturer of temporary tent structures (used in many different market segments, such as events and the hospitality industry, for the sports sector and industry).

Due to the lower temperatures required for the underfloor heating, an air-cooled VRV Chiller was the preferred solution, on economic and environmental grounds. The chiller CO2 emissions are 33 % lower than with an oil heater. The heat for the hall – 3800 m2 large and 8 m high – and the 600 m2 attached offices, is provided by three 75 kW split chillers running independently. The advantage of split chillers is having the heating water heat exchange inside the building.

The system operates in an outside temperature range from -15 C to +43 C, and inverter controlled VRV chillers are able to adjust constantly to the heating demand, ensuring high comfort while keeping energy load minimal.
