Embodiment Construction
[0026] All figures are to be understood schematically. Scale representations have been disregarded for the purpose of improving the clarity of the drawings.
[0027] exist figure 1 An embodiment of a heating and / or air-conditioning device 1 is shown in vertical section, which is mounted on the roof 51 of a ground vehicle, eg a bus. Below the housing cover 3 of the heating and / or air-conditioning device 1, a fresh air fan 5 and a circulating air fan 7 are arranged on the right, each in the form of a radial fan, each with a direction toward the left. Downwards is the discharge direction through the discharge openings 9 and 11 into the vehicle interior 53 , which is formed, for example, as a passenger compartment. Correspondingly, embodiments of the fresh air fan 5 and the circulating air fan 7 are also conceivable as, for example, double radial fans or axial fans or cross flow fans, respectively. For the fresh air to be sucked in by the fresh air fan 5 , there is an inlet ope...

The invention relates to a heating and / or air-conditioning system for a ground vehicle, comprising at least one circulating air fan and at least one fresh air fan, wherein the heating and / or air-conditioning system at least also has an exhaust gas conveying device for conveying exhaust gas from the interior of the vehicle to the outside into the environment, and the rotational speeds of the circulating air fan, the fresh air fan and the motor of the exhaust gas conveying device can be adjusted independently of one another, wherein the at least one circulating air fan is designed only to convey circulating air and the fresh air input is designed such that fresh air can be blown into the vehicle interior only without mixing when the at least one fresh air fan is operated. Thereby, a ventilation of the vehicle interior space of the ground vehicle comprising a delivery of exhaust gas is achievable. The invention also relates to the ground vehicle having such a heating and / or air-conditioning system and to a method for controlling the heating and / or air-conditioning system.
Description
technical field [0001] The invention relates to a heating and / or air conditioning installation for ground vehicles. The heating and / or air-conditioning system comprises at least one circulating air fan for supplying circulating air with respect to the vehicle interior and at least one fresh air fan for supplying only fresh air to the vehicle interior, and also at least An exhaust delivery device that conveys exhaust from the space outward to the environment. The heating and / or air conditioning system is used in particular in construction or agricultural vehicles. Furthermore, the invention relates to a ground vehicle, ie a vehicle designed for forward movement on the ground, for example a road transport vehicle, an agricultural vehicle or a railway vehicle with such a heating and / or air conditioning device and to a vehicle for controlling method of the device. Background technique [0002] Air conditioning systems for ground vehicles generally comprise a refrigerant circu...
