Scopes of delivery

BlueCool Drive 40 – auxiliary air-conditioner for ​motorhomes The BlueCool Drive 40 system was developed specifically for air-conditioning the ​motorhome’s living space while driving. The air-conditioner impresses with 4 kW cooling ​capacity and is thus one of the most powerful of its kind on the market. The system ​utilizes partially existing components of the vehicle’s own air-conditioning system and is ​integrated into the refrigerant circuit of this system. Uniform cooling of the entire interior space The use of the vehicle’s own air-conditioner and the BlueCool Drive results in the ​creation of a total cooling system that enables uniform cooling of the entire interior s​pace of the vehicle.

 The air-conditioning system is operated via the running vehicle engine.  The refrigerant is compressed in the compressor A and thereby heated to a high temperature.  Now under high pressure, the refrigerant is conveyed to the condenser B , where it is cooled down and liquefied. In so doing, it gives off heat to the surrounding air.  Part of the refrigerant is now supplied to the vehicle’s own evaporator C which also cools the driver’s cab. How the air-conditioning system functions:

 The other part of the refrigerant is conveyed to the newly installed evaporator D where the refrigerant evaporates, thereby absorbing heat. This heat is withdrawn from the induced air of the cabin, so that cooled air is blown into the living space of the vehicle.  The passengers in the living space can now set their own climate comfort via the control element E in which they can choose from blower levels 0, 1, 2 or 3.
