Internal environments are extremely important when considering the comfort and wellbeing. Marjory Kinnon and Oaklands educational facilities, two Middlesex based special educational needs and disabilities schools (SEND), recently both moved into new purpose-built premises offering state of the art facilities capable of delivering quality learning in a safe flexible environment for 512 pupils that attend.
In order to provide building preheat, a commercial heat pump system adopts an air recirculation mode and uses the integral heat pump circuit to provide air up to 18oC into the building. Low temperature hot water [LTHW] coils mounted in local ductwork provided localised boosts and closer control to individual areas.
