If you have a warm air system it is a relatively easy task to add air conditioning thereby offering you all year round comfort.

To add air conditioning to your system you simply need to fit a DX evaporator coil to the supply side of your warm air heater and link this to an external condensing unit. The external condensing unit supplies a refrigerant to the DX evaporator coil which removes heat from the air in the same way as domestic refrigerator cools your foood.

There are two types of DX evaporator coil used in domestic applications one for upflow systems and one for downflow. There is also a third option which is a horizontal DX evaporator coil but this is rarely used in domestic applications in the UK although it is frequently used in commercial applcations.

The external condensing unit is also available in two types. a cooling only option or a heat pump option. We have detailed a special offer we are making with regard using the heat pump condensing unit in conjunction with a Lennox G61MPVT warm air heater.

The Lennox HS40 (Cooling option) and the HP40 (Heat Pump option) are available in both single phase and three phase electrical supply. In general terms the single phase unit will give a cooling duty up to 10kW while the three phase option will give a cooling duty up to 18kW. Both the HS40 and HP40 units work on R407c refrigerant.
