Cab Cooling & Ventilation
A Solution Without Idling; Safe and Simple.
Dew point cooling technology is the preferred concept for cab cooling and ventilation. It combines high energy efficiency with low weight, low noise and low maintenance, making it the key technology to meet the requirements of the new anti-idling laws. The transportation TechnologyR&DCenter estimates the average annual fuel costs for idling at $3,500. Avoiding these costs provides additional justification for fleetowners to invest in this new technology. Oxycom developed a new cooling technology based on indirect evaporation of water. In the compact, highly efficient counter-flow heatexchanger (the Oxycell X-Changer) direct contact between the water evaporation process and the cooling air is avoided.
Benefits
- Excellent cooling performances
- Less air-turbulence in cabin
- No humidity increase in cabin creating more cab comfort
- Above all, no hygiene risks because the cool supply air will never be in contact with the water vapour
- Automatic switch to cabin air recirculation when outside air is polluted
- Low-weight, silent
- Low consumption of water for the evaporation process
- Impression of Oxycell based product; Roofmounted or back-wall mounted.
DAF/Paccar Test 2005
The concept of an Oxycell based Cab Cooler was tested with DAF in Holland (a Paccar company) showing spectacular results:
- As stand-cooler the Oxycom unit provides adequate cooling, creating a comfortable climate during the day and night.
- The recirculation possibility shows positive effect on cabin indoor air quality.
- Compared with existing solutions an Oxycell based Cab Cooler is less expensive, lighter more hygienic and shows excellent cooling performances.
All Season Functionality
With the Oxycell X-Changer it is even an option to bring in preheated intake air in winter without using extra heating energy. In wintertime, when outside temperatures are uncomfortable cold, the Oxycell can be switched to heat-recovery. Before flowing into the cabin the cold supply air is heated up in the Oxycell X-Changer by transferring heat from the hot cabin exhaust air with an efficiency of 90%.
Cooling Functionality in More Humid Areas In hot and dry climates the system can be operated all day, either with or without the engine running, to keep the driver cool. In more humid climates, when the cooling capacity from the evaporation process is reduced, an optional drying rotor can be added to dry the intake air before it enters the cabin through the Oxycell. When parked the surplus heat of the switched-off engine can be used to regenerate the drying rotor, avoiding the need for additional energy consumption to dry the air.
Runs Directly From Battery
The Oxycell based Cab Cooler is powered directly from the battery. No investment in costly (and noisy) generators, expensive energy storage systems or inverters are needed. In high capacity cooling mode the electrical consumption is approx. 8A. (at 24V.), in ventilation with heat recovery the consumption is less than 3A.
Healthy Cab Environment
Taking air from outside is pleasant, however on truck-parking places this intake air can be highly polluted. The set-up of an Oxycell based product also allows for 100% recirculation of the indoor cabin air.
Simplicity in Technology
The only moving parts in an Oxycell based product are the fan(s) and the water supply and exhaust pump. Compared with compressor-driven air-conditioners the number of moving parts is minimal. Especially the avoidance of a compressor and a high-pressure cooling circuit make Oxycell based cooling products far more robust, maintenance friendly, lighter and silent.
