Project Scope

This project involved the supply and installation of mechanical and electrical services for a refurbishment project in Chelsea, London.
The building consisted of two properties that had been joined to create one large private residence. The property comprised of a sub-basement, basement, ground, first, second and third floor.

The works included:

LTHW systems Heat recovery ventilation systems Water treatment & filtration systems
Underfloor Heating Humidification systems Rainwater harvesting systems
VRF comfort cooling Distilled water service Electrical distribution equipment
Water treatment systems UV treatment Lighting circuits
Domestic water systems Leak detection system Lighting control and dimming
Gas installations Fire suppression systems Supply & installation of luminaires
Dry risers CHP system Small power
Sprinkler systems Acoustic package Fire alarm
Above ground drainage High end sanitaryware fit out Security systems
Automatic Controls Swimming pool AHU & ventilation systems Audio visual systems

The Priory Approach

A major part of the project involved engineering a method of controlling the building’s humidity to protect the artwork displayed throughout.

To control individual room humidity we installed ultrasonic humidifiers, fitted within each of the VRF fancoil units. A discrete thimble type sensor measured room humidity and was wired back to the UFH manifold IQ controller serving the area. This controller produced a 0-10V control signal to modulate the humidifier and maintain the correct level of humidity.

Before activating the humidifier, the VRF fancoil unit must be in heating mode with the adjustable air temperature setpoint at the correct level. To ensure this happens we installed a duct mounted temperature sensor in the airflow supply to measure the air temperature. This was wired back to the UFH IQ controller to prevent the humidifier operating before achieving the required temperature.

“LTS have recently completed a large residential project in Chelsea where Priory were the mechanical, electrical and public health subcontractor. The Priory works alone was valued in excess of £2m to provide the complete services installation on this project. Throughout the works Priory and their team provided a high level service, working closely with other subcontractors appointed and integrating well in elements where input was required by a number of trades. LTS look forward to working again with Priory and would not hesitate in recommending them as a mechanical and electrical services provider.”
