MJD were contracted to supply and install 10no Mitsubishi HMA100V Heavy Industries air to water heat pump boiler systems. The aim of the project was to deliver proven heat pump technology to deliver effective, low carbon heating and hot water, Mitsubishi Electric's award winning air to water heat pump systems provide a simple, renewable solution that rivals traditional heating systems.
Main Contractor- Fulstow Holdings.
During the beginning of the project MJD were contracted to decommission and remove the original Mitsubishi air conditioning equipment. Full reclaim of all refrigerant gas was carried out and all existing units removed from site for re-cycling purposes.
MJD supplied and installed the Daikin ducted fan coil units which were connected to several Daikin Mini VRV air conditioning systems. The Daikin VRV option was selected for its flexibility in residential applications. All indoor fan coil units were concealed within loft spaces or bespoke cabinets. All conditioned air was fed via white linear grilles. The system is controllable via a laptop or mobile phone application.
MJD supplied and installed a Mitsubishi four way blow cassette system to the clean room/ test Laboratory. Mitsubishi was the preferred equipment choice for the following reasons. The airflow is controllable for ceiling heights up to 4.2 metres with automatic adjustment of fan speed. Reduced draught air distribution with independent vane control. Filter lowering operation down to 4metres.'I' see sensor for energy saving and smooth temperature control throughout the room. MJD also provided a Lossnay system to provide fresh air and extract to the enclosed room. The Lossnay unit works in conjunction with the air conditioning system recovering energy that would have otherwise been wasted. The units reduce overall energy costs by extracting stale air and then recovering the heating or cooling to either warm or cool incoming fresh air. By utilising this energy the Lossnay system can save up to 40% on initial capital costs of heating and cooling plant by reducing the load of the occupied space.
Project- MJD were contracted to carry out the replacement of the church heating system. The church had been previously heated via high level electric infa-red heaters. These were proving to be very expensive to run. The decision was made to employ a consultant who would investigate a cheaper form of heating. The following system was approved and MJD were instructed to carry out the required works.
Two Mitsubishi Electric 2 Pipe PUHY-EP-250YJM Heat Pump Systems, providing a total heating capacity of 63KW.
The indoor units consisted of the following: Wall mounted fan coils units: Floor Consoles.
The systems have been fully commissioned and handed over to the client. A maintenance contract has now been put in place, which has in turn activated a five year parts and labour warranty.

Project- To supply and install 25 Daikin Inverter Heat Pump Air Conditioning Systems (Energy Efficient)
Main Contractor- MJD Air Conditioning Services Ltd
MJD were contracted by Veritek to carry out the removal of the existing LG air conditioning equipment.
All systems were fully decommissioned and all of the existing refrigerant gas reclaimed as per the current ‘F’ gas regulations.
All of the existing equipment was removed and sent to AC Salvage for re-cycling purposes. The new Daikin high efficiency inverter systems were then installed, commissioned and handed over to the client.
The main workshop areas were supplied with Daikin four way blow roundflow cassettes. The main administration offices, meeting rooms and the reception area were supplied by ducted fan coil units. We feel this was the perfect solutions for these areas, minimising draughts for the office personnel and creating a comfortable working environment. All areas were fitted with remote temperature sensors to improve efficiency and prevent temperature swings. All of the systems have been fitted with the up to date Daikin time clock controllers to provide maximum efficiency.
A five year parts and labour warranty will be in place when the service contract is signed and agreed.

Project- Mitsubishi City Multi Heat Recovery System
The aim of the project was to provide all of the mechanical services required for the heating, cooling, ventilation, and the hot and cold water services. All of the main areas and meeting rooms were be fed with Mitsubishi ducted systems which were located in all of the adjacent false ceiling voids
The conditioned air was fed into each room via 600 x 600 four way blow white diffusers. All fresh air was installed into the false ceiling voids and fed through the back of the fan coils. Ducted units were chosen for quiet operation and to minimise the draughts within the training rooms. All rooms were supplied with extract air to assist in keeping the rooms to their optimum levels
The system was a Mitsubishi City Multi system which provided simultaneous heating and cooling through its unique two pipe system, offering versatility when required. The fresh air and extract was provided by a Mitsubishi Lossnay unit which provided the correct amount of fresh air/ extract to all areas.
As MJD were contracted to carry out the hot and cold water services, we decided to introduce a Mitsubishi Heat pump boiler onto the system, this would be an economic way of producing hot water as the training rooms are generally running in the cooling mode five days a week and all of the rejected heat would be absorbed into the hot water system.
The system was ECA registered and a saving of 23% was made on the entire installation costs.

We have previously fully air conditioned Level 1 using a Daikin three pipe VRF system, which is still fully functional and maintained on regular service intervals by MJD. Our latest project for Brockton Capital was totally designed by MJD Air Conditioning Services Ltd. Eventually it was agreed that a Mitsubishi City Multi 2 pipe system would be installed on level 2 to provide Cooling , Heating, and hot water. The need for energy efficiency was paramount in the design stages to meet current regulations and legislations. The system was designed with the Enhanced Capital Allowance Scheme (ECA) so that Brocton Capital would benefit from utmost efficiency both financially and environmentally. Visit www.eca.gov.uk for further information. The external condensing unit was lifted to the roof early on Sunday 27th February 20111 by Tonhout Crane Hire Ltd, with a partial road closure. The unit was craned to the sixth floor roof top and positioned on the required condenser base. All of the existing systems serving level 2 were removed for recycling at Ampthill Metal Company
All areas were served by concealed chassis units enclosed in bespoke panelling and the air distribution to each area was provided via bronze linear grilles. All of the meeting rooms were fitted with wall mounted temperature sensors for optimum temperature control. A lossnay heat exchanger was installed to provide conditioned fresh air to all areas and extract air to keep the quality of air as pure as possible within all of the meeting rooms, reception area and the library. The lossnay unit will save around 30% on initial capital costs of the heating and cooling plant by reducing the load of the occupied space. The system is capable of utilising free cooling by using the outside temperature to help achieve the required temperature by free cooling or heat recovery.
A VRF Heat Pump Boiler was connected to the City Multi system. Hot water was provided for the kitchen area, sanitary areas including the shower room. The heat pump hot water boiler is far more efficient than a conventional gas boiler and will reclaim any heat dispersed when the main system is running in the cooling mode, providing free or cheap hot water.
