VRF climate control for MBZ facility
A new state-of-the-art Mercedes-Benz retail centre now under construction will be air conditioned with Toshiba’s award-winning Super Heat Recovery Multi (SHRM-e) variable refrigerant flow (VRF) system
L
ocated on a 10.5-acre site near Stockport, the development will be the largest Mercedes- Benz facility in the UK, and includes the
brand’s largest showroom in Europe, 32 workshop bays and a high-tech body and paint repair facility. Toshiba Carrier UK is a joint venture between
Toshiba and Carrier in the United Kingdom. The project is the first in a series of new build schemes planned by Hong Kong-based retail group LSH Auto UK, which currently operates nine Mercedes-Benz dealerships and smart retail centres in the Manchester and Birmingham areas. The main contractor on the project is RG Group with Imtech Engineering Services North responsible for mechanical and electrical services. Air conditioning will be provided by 18 Toshiba
high-efficiency SHRM-e VRF outdoor systems connected to 124 indoor units, all ducted to deliver a high-quality interior finish. In addition, Toshiba cassettes are being installed in administration offices. The equipment is being supplied by Toshiba distributor Cool Designs. Gavin Horner, who led the project for Toshiba,
said: “The showroom is a double height, open-plan design with adjoining offices, which offers significant potential for heat recovery. The heat pump-based Toshiba system will harness waste heat energy and deliver it in the form of heating or cooling to wherever it is needed in the building, making maximum use of available energy and minimising running costs for the end user.” SHRM-e is Toshiba’s latest three-pipe heat recovery
VRF air conditioning system. It sets a new industry standard for efficiency and continuous heating, achieving a world first of eight European Seasonal Energy Efficiency Ratio (ESEER ) in most capacities. SHRM-e also delivers improvements across the
board in terms of occupant comfort, ease of installation and breadth of building application. This has been made possible by developments in key technologies such as the compressor and intelligent control system, supported by a battery of incremental improvements in almost all system components. The system is controlled by four touchscreen
controllers, offering quick access to key operating parameters via a colour screen. Each can control up to 64 indoor units, offering a user-friendly interface for enhanced user comfort and system performance.
AC RANGE INCLUDES ‘FOLLOW ME’ FUNCTION B
osch Commercial and Industrial has announced the launch of its new range of air conditioning splits with environmentally
friendly R32 refrigerant for the fast-growing UK domestic and commercial markets. The new range covers single split residential air
conditioning (RAC), single commercial air conditioning (SCAC) and multisplit units with DC inverter technology. The range is described as highly efficient with ErP rating of A++ for cooling and A+ for heating for both RAC and SCAC units and A+/A++ for cooling and A for heating of multisplit units. A key feature of the new range is the introduction
of refrigerant leakage detection. This ensures the safety of users and environment while protecting
the compressor from being damaged by shutting down the unit and warning users in case of a leak. The Bosch RAC split range is available in four
different cooling outputs: 2.6kW, 3.5kW, 5.3kW and 7kW with wall mounted indoor units. Bosch SCAC range is available in 5.3kW, 7kW,
10.5kW 1-phase; 14kW 3-phase cooling output models with a possibility to choose between cassette type and duct type indoor units. With the Bosch multisplit range, it is possible to
connect two to five indoor units to one outdoor unit. It is available with two types of indoor units –wall mounted type and cassette type. It provides an optimal solution for a wide application range from family houses to small offices. 5.3kW, 7.9kW, 10.5
kW and 12.3kW cooling output models are available. The range also features a “follow me” function
which transfers the conventional room temperature measuring function from indoor unit sensor to a built-in wired or wireless controller sensor. This allows the unit to accurately maintain the temperature according to the user’s location. “Air conditioning in the UK is a fast-developing
market, so we are extremely excited to be serving both domestic and commercial markets with our R32 range,” says Tim Davies, director at Bosch Commercial and Industrial. “At Bosch, we are also committed to driving down the energy bills of our customers and lowering the emissions from their properties while optimising their comfort levels.”
