Case Studies
London Airport
Within the airport we were tasked with providing air conditioning to many of the large open areas. The scale of the work was extensive. All the work had to be completed whilst the airport continued to remain open. The entire project required bespoke design and special consideration had to be taken as some of the work needed to be completed on airside. We completed the work within security control, duty free, departure/arrivals pier A/B, Easy Jet crew room and prayer room amongst many others. We also replaced one of the large chillers which provides water to the majority of the airport. The entire project took almost a year and has continued to work without fault.
Moor Park Golf Club
The “Orangery” is situated within a 17th century manor house and is used by Moor Park Golf Club as a function room and restaurant to accommodate weddings, parties and conferences.
Watford Refrigeration & Air Conditioning were asked to provide comfort conditions throughout the year in the restaurant area.
Owing to the unsuitability of the ceiling structure it was not possible to install ceiling mounted units and therefore wall mounted heat pump systems manufactured by Daikin were installed. Interconnecting refrigeration pipework and signal wiring went through the Orangery wall into the loft area, running to the kitchen roof at the rear of the building. Consideration was given to the aesthetic detail due to the historic nature of the building.
We were able to provide unobtrusive heating/cooling thus giving the conditions required to the complete satisfaction of the client.
This installation is covered by an annual maintenance contract which includes a 24 hour call out facility.
W. Jordan (Cereals)
Open plan and individual office areas in the recently built warehouse suffered extreme heat in the summer and cold in the winter.
To maintain pleasant working conditions within the office areas Watford Refrigeration & Air Conditioning designed and installed an air conditioning system to cope with these intense conditions.
The office areas required the air conditioning to run 24 hours per day, 7 days a week. Each individual office area and the open plan area required its own temperature control and on/off function.
Watford Refrigeration & Air Conditioning designed and installed a system that would produce simultaneous heating and cooling for each individual area, all being controlled via a centralised controller and remotely accessed P.C. Operating costs are kept to a minimum with the use of inverter controlled systems.
The installation works were carried out during normal working hours by our experienced and qualified engineers who worked alongside Jordan’s staff during their routine working day.
The end result is an office environment that maintains a constant and comfortable atmosphere throughout the year, completed on time and to the client’s satisfaction.
The air conditioning systems benefit from a service and maintenance package offering 24 hour standby.
Smiths Detection
Smiths Detection is part of the global technology “Smiths Group”. It designs and manufactures sensors that detect and identify explosives, chemical and biological agents, weapons and contraband for both the civil and military markets.
Design requirements – Watford Refrigeration & Air Conditioning Limited were employed to design and build a 110M2 class 10,000 clean room, along with all associated mechanical and electrical services.
The installation works were carried out on the 4th floor where access was limited and adjacent areas were still occupied. With this in mind the installation was carried out to suit the client’s required programme and the whole project was completed on schedule to the client’s satisfaction.
Post installation maintenance – Watford Refrigeration undertake regular maintenance of the refrigeration and air conditioning systems serving the above to ensure optimum performance throughout the year. 24 hour emergency cover is also provided.
Faulkes Reflecting Telescope
Telescope Technologies manufactures robotic telescopes, designed to be remotely operated from Liverpool John Moore’s University.
The telescopes are housed in an insulated steel “clam shell” that opens up fully to expose the night sky for the full 180 degrees of arc, and significantly, the ambient temperature and local weather conditions.
The 24 tonne telescope assembly floats on a hydraulic bearing, which whilst facilitating manoeuvring, carries the risk that the heating effect of the high pressure hydraulic oil supplied to the base of the assembly could cause the structure to expand, thus affecting the critical focussing of the telescope.
Watford Refrigeration were tasked with providing the design and construction of a packaged hydraulic oil cooler that would operate at altitudes up to 4000 M, in ambient ranging from -15 deg.C. to +36 deg.C. provide 10 kW of cooling and control the hydraulic oil temperature to within 3 deg.C. of the prevailing ambient temperature.
The resulting package combined a modified Daikin Glycol Chiller with a control module incorporating a glycol pump, three port valve, glycol to oil heat exchanger and temperature monitoring and control panel.
Weather permitting the telescopes have been in operation since 2006 with the hydraulic oil temperature being maintained within +/- 1 deg.C. of the ambient.
Refrigerated Vertical Storage System
Watford Refrigeration were tasked with solving a lack of space issue within a local laboratory. The laboratory required a huge amount of cold storage for medicine. As their warehouse was tall but limited in floor space, we created a lift system to store all their products at the required temperature whilst also making it easy for staff to remove the medicine whilst maintaining the temperature within.
This was achieved by creating a room attached to a modular stack design which has an automated system in order to pick and choose which medicine they required. The lobby of the room is also refrigerated so that at no point is the temperature varied prior to removal of the medicine.
