Café in Covent Garden, London.
Ground floor & basement café seating area getting very hot day & night with no outdoor space for traditional air-cooled condensing units; or floor space inside the café for portable air conditioning.
Install water-cooled split system air conditioning. The condensing units are much smaller and can be located in confined spaces as opposed to being outdoors.
If the premises water supply is on a water meter, it can result in very expensive water bills if not installed with a water loop passing through an independent chiller.
In a building where a central supply of water is available, you can match various split fan coil units with water cooled condensing units to suit your application. Water cooled condensers offer flexibility in location since it is smaller than a conventional air cooled condenser and does not need an external balcony or wall to install.
Basement Training Offices in London EC2.
Stuffy office with limited ‘fresh-air’ brought into office at street level through outdated ventilation system. Heat generated by people & computers. No obvious outside area to locate condensing units. Office regularly too busy to close during weekdays for installation to take place without loss of revenue.
Install ceiling cassette single-split-systems throughout, connected to condensing units located in various light wells accessed through the ground floor. Work carried out over two weekends so no disruption to clients work schedule.
Private four-story town-house overlooking the River Thames.
River views are south-west facing with large windows creating solar heat gains throughout the property. This was a family home with young children so open windows were not an option, even if considering portable air conditioning. In addition, space was limited for outdoor condensing units.
A multi-split-system was installed. In this case one outdoor unit supplying cooling to four indoor units. The condensing unit being located on a roof terrace.
The premises are detached, single story; and in an exposed location. Inside the layout is mainly an ‘L’ shaped open-plan area plus individual rooms & offices difficult to heat evenly; with limited electrical power coming into the building and no gas or oil for what might be considered traditional heating methods.
Current heating limited through small, expensive to run electric wall heaters.
We installed nine energy-efficient inverter single-split-systems of varying types & outputs. Outdoor condensing units located on the flat roof above, out of sight and away from the children.
Provides cheaper heating bills & the benefit of comfort cooling in the summer.
Too expensive to heat in the winter, too hot to enjoy completely in the summer. During the day windows can be opened to vent hot air, but at night the windows need to be closed due to flying insects.
Install a 5kW energy-efficient inverter single-split-system to heat & cool; running costs approximately 10pence per hour (depending on individual energy provider’s tariff).
Lots of heat sources including east & west facing walls being constructed mainly of glass. Numerous staff, computers & printing equipment. Client not allowed to hang condensing units on any outside wall.
We built a small plant room within the boundary of the premises to house the condensing units; replacing two large double glazed windows with custom secure grille panels to let the heat out. The grilles were backed with insect mesh to prevent insects getting into the building. We then installed energy-efficient inverter single-split air conditioning systems for two large printer rooms and a variable refrigerant flow system (VRF) using one large chiller to supply heating & cooling through ceiling cassettes for the occupied part of the office and meeting room.
