New air conditioning shows its energy-efficiency scope
More efficient air conditioning for a computer-science laboratory at the University of Manchester has been provided by replacing an outdated system with a VRF heat-pump system from Mitsubishi Heavy Industries. The 2-pipe system for the laboratory in Sackville Street is from the KX6 range and uses R410A. It achieves a COP of up to 3.4 and was installed by the northern region of Mitie Engineering Services with equipment supplied by 3D Air Sales.
The installation comprises a 56 kW inverter-controlled heat pump outside serving six wall-mounted indoor units with cooling/heating capacities of 7.1/8.0 kW. They have a front panel that can be opened and closed from the bottom for easy access to detachable filters.
The indoor units are individually controlled by six wired remote controllers, which give access to service and technical data. Upper and lower temperature limits can be specified separately within a set range and adjusted as required to avoid excessive heating or cooling.
