Hi Oli,

It is to describe the quick couple connector that allows you to connect the internal unit to the external unit without use of specialist air conditioning tools.

Our couplings do not require torque wrenches, spanners, or vacuum pumps, and simply click together, which automatically releases the refrigerant around the system. It also means it can be disconnected in exactly the same way and re-installed in a different location for example.

This process can be repeated hundreds of times, without refrigerant loss or ingress of moisture etc.

It means itcan be DIY installed without the need of specialist tolls are paying engineers prices!!

Hello Simon

Engineer Robert came on Friday and unit now AOK; also invoice has arrived in post. Thanks for all your help. Have recommended you to a few friends and contacts so you may get some more business from south London.

Dear Jeremy,

Thank you for your air conditioning enquiry.

The answer to your question:-

Hi,

Can you tell me the difference between this model and the 12000 DC inverter? I notice the inverter is more expensive, but I’m unclear as to what extra it does?

Many thanks,
Jeremy

The DC Inverter is a more efficient machine that costs less to run and is more even in its temperature control due to having a variable speed compressor within the condensing unit.

A standard Fixed Speed Air Conditioning System works by cooling or heating the room towards the set point you have indicated on the remote controller, then once it has reached that temperature it turns the external condensing unit off. Once the temperature raises or drops (depending on the mode you are on) it cuts back in to resume its function. This way the external condensing unit has a lot of start/stop load and due to the nature of the condensing unit cycling, the temperature has a differential of 2- 4 degree C.

An inverter air conditioning system, works in the same way apart from when it has made temperature (according to the set point), it slows down the external condensing unit (rather than shutting it off completely). Once the temperature begins to rise or fall (again depending on the mode you have selected Cooling/Heating) the external condensing unit speeds up or slows down making the power consumption far less, as there is less start/stop load, and also because it is not shutting down as often, the temperature is much closer to the set point. The DC Inverter is 0.5-1 degree controllable.

The DC Inverter is 320%* ( *heating mode 200% cooling mode) more efficient in power consumption than the fixed speed. However the cost of the DC Inverter is higher, if you are using the dual function it will save you money over time.

If your main concern is cooling, and heating is not really a requirement, it may be prudent to go for the cheaper unit, as it would take a long time to justify the cost difference, however if heating is just as important, then the DC Inverter would make up the cost difference over a shorter time.

The DC Inverter also works to much lower outside ambient conditions, is quicker to heat/cool the room and is generally quieter due to the relays not being engaged every time it cuts in and out.

If you would like to know more or have any queries regarding this response. Please do not hesitate to contact me.

Best Regards

Simon

Dear Ishtiaq,

I would contact the firm in Portsmouth who imported it for you. All our units are Japanese manufactured in China, and as such the wiring on our units is all to U.K specification. In fact I thought it was illegal now to import goods into the U.K without the correct power supply attached due to H&S fears.

I cannot advise you exactly as it could be a danger to yourself. The electrician should be able to check back to the indoor unit board to see the live side on the PCB.

I would contact the company you purchased from, stating the requirement to have a U.K specification power source attached to any electrical appliance brought into the U.K

Best Regards
