Job Desription: Controls Upgrade to an Airedale DX Heat Pump
Area: Savannah House, London
Issue Identified: Following an on-site attendance many control items, such as the PCB controllers and main control boards have become obsolete and non-functional with no manufacturer assistance.
Our proposal offered a major cost saving over new equipment which will maximize the efficiency of the existing unit and will enable ‘open protocol’.
Additional benefits are: Effective life cycle extension 2-5years (controls) + (this based on a strict maintenance and treatment plan & subject to new Refcom alteration plans), reduced energy requirement (circa 2.5 – 5% + power reduction), refrigeration system & chiller control and mechanical improvement due to controls, minimal building disruption (unit upgrade carried out whilst keeping the building operational), ease of use to assist building service engineers.
Works carried out:
CONTROLS UPGRADE
- The existing controls/dials were replaced with new Carel PCO5 units, which represent the most advanced offering available in the field of programmable controllers. The system selected for this application included bespoke strategy.
- These controllers and boards were installed into current electrical plates.
- New sensors were fitted to the circuit of the unit and wired back to the control boards in addition to the replacement of all safety devices.
- All data was logged and documented during the commissioning process and a copy of the operational report and Carel PCO5 controller’s configuration was given to the client.
- We also provided onsite training to staff on the PCO5 chiller controller.
