Case Histories

Data Centre, Fareham, Hants

This project involved the design and installation of a first floor heating and cooling system as well as the ventilation.  Energy efficiency was paramount. The RJC solution involved the installation of a heat recovery fresh air system. The system allows the temperature difference in either heated or cooled air to be recovered through a heat exchanger and then used to heat or cool incoming fresh air.  This gives a level of free heating and cooling, reducing the running costs of the main air conditioning systems. 

The inverter technology utilised within the condensers, allows the client to maintain COP’s of 3-4 providing extremely efficient heating and cooling, far in extremes of that offered by a conventional wet heating system.

The ground floor houses the clients’ computer and processing systems which are crucial to the running of their company.  These require a constant low temperature and humidity level to maintain the effectiveness of the equipment.  The floor has been fitted with 100% backup, fed through generators. Via a building management system, the temperature can be maintained at the desired levels, even in the event of a major power failure.

All systems comply with new government part L legislation.

Flagship Store, Manchester

Working in conjunction with one of the UK’s most reputable mechanical companies, we installed heating and cooling air conditioning in this major high street retailer’s flagship store. Located within Manchester’s new Arndale Shopping Centre, the high spec store is spread over three large floors. Along with the pressures of opening the store on schedule and handing over the systems on time and working effectively, attention to detail was imperative.

The store is now fitted with seven large heat recovery systems. These allow units to operate from their return air sensors and keep each area of the store at the desired temperature.  Because the floors are vast and due to the amount of glazing and changes in lighting, temperatures vary within specific areas. This means that some of the units are in cooling mode while others are in heating.  Heat recovery technology allows this to be achieved within a single system and can be applied to office and shop areas alike.

Student Loans Centre, Darlington

The site now houses the largest gas powered VRF heat recovery system in Europe. Supplied and installed by RJC working closely with the mechanical contractor and consultant, we were able to install the system on time and to programme, to an exceptionally high standard. 

The project utilises the latest technology from a leading manufacturer, using gas as the main source of power for the condensing unit rather than electric.  This type of system is ideal for buildings in which electricity is a scarce resource.  With so much computer and electrical equipment in use in  modern offices, electricity supplies can often be stretched to their limit.  This type of system means the client does not have to pay colossal electricity bills or suffer huge disruption when increasing the electrical supply to the building.

The system can provide both heating and cooling. Combined with heat recovery technology, this means that separate offices/areas can be in different heating and cooling modes at the same time, depending on the occupants’ comfort levels.
