Definitions

  • the invention relates to an air conditioning system and a method for air conditioning the interior of a vehicle, in particular a rail vehicle.
  • an air conditioning system with a central air conditioning unit is used, the output of which is connected via an air supply duct to at least one compartment or vehicle area of the vehicle, each compartment or each vehicle area further comprising a temperature sensor connected to a compartment control unit for measuring the internal temperature and at least one forced ventilation , floor heater controllable by the compartment control unit.
  • a considerable disadvantage of known air conditioning systems is that there is an unsatisfactory temperature distribution within the compartment in cooling operation due to the introduction of the cooling air in the floor area.
  • the arrangement of the supply air duct in the floor area has furthermore the disadvantage that it takes up a lot of space in the floor area and therefore undesirably restricts the passenger compartment.
  • the comfort of a vehicle interior depends very much on the uniformity of the temperature stratification. In cooling mode, this is possible by introducing cooled supply air preheated to a certain temperature into the interior from above. Since such a system is also used to heat this interior, the temperature stratification of these systems in heating mode is generally such that warm air bubbles form in the ceiling area and a so-called cold air lake forms in the floor area. This inadequate temperature stratification in heating mode can be considerably improved by additionally operating floor radiators with constant output. If the compartment or vehicle door is opened frequently, however, this measure is inadequate, since new cold air flows into the floor area, particularly in the case of rail vehicles, and the additional heat required is supplied in the ceiling area, which means that the cold air lake, which repeatedly occurs in the floor area, heats up only very slowly becomes.
  • the invention has for its object to provide an air conditioning system and a method for air conditioning the interior of a vehicle, in which the disadvantages of known devices are eliminated and a uniform temperature stratification is generated in both heating and cooling mode.
  • this object is achieved on the basis of an air conditioning system of the type mentioned at the outset, in which the compartment control unit is connected to a secondary heating element, via which supply air flows into the compartment from above, this compartment control unit controlling the output of the floor heating element as a function of the temperature sensor during heating operation and the like Post-heating element is controlled so that the temperature of the supply air is kept approximately constant, and this compartment control unit controls the power output of the post-heating element as a function of the temperature sensor in cooling mode when the floor heating element is switched off.
  • Each compartment control unit 3 of a passenger car is connected to a system control unit 9, which is also connected to the reheater 8 via the changeover switch 7, all of them Afterheater 8 of a car are each connected to the system control unit 9 via such a switch 7. Furthermore, this system control unit is connected to the air conditioner 10 of the passenger car and connected to a duct temperature sensor 11 and an outside temperature sensor 12. The fresh air outlet of the air conditioning unit 10 integrated in the ceiling area of the passenger coach is connected to a supply air duct 13 which extends in the longitudinal direction over the entire passenger coach. In the ceiling area of each compartment 2 there is a reheating element 8 within the supply air duct 13. Furthermore, the duct temperature sensor 11 is installed in the longitudinal direction approximately in the middle of the passenger car in this supply air duct 13.
  • Fig. 2 the air conditioner runs in cooling mode.
  • the changeover switch 7 and the switch 5 are in the position K, so that the reheater 8 is controlled via the compartment control unit 3, the floor heater 6 being switched off.
  • the supply air supplied by the air conditioner 10 is preheated individually for this compartment, depending on the compartment temperature sensor 4 and under the control of the compartment control unit 3, before entering the compartment 2 by the reheating element 8.
  • the temperature of the supply air supplied by the air conditioning unit 10 is therefore preferably somewhat below the lowest target temperature set in a compartment 2 of this passenger car. This cooled and optionally preheated supply air flows in the ceiling area essentially vertically downwards into compartment 2.
  • the circulating air flowing in the floor area essentially horizontally from the floor heating elements 6 into the compartment is heated depending on the compartment temperature sensor 4 and under the control of the compartment control unit 3.
  • the preferably horizontal inflow of the heated circulating air additionally accelerates the clearing out of the cold air lake which arises in the base area, in particular when the compartment door is opened.
  • Criteria for the system according to the invention to run in cooling or heating mode or when this system is to be switched to the other operating mode can be defined in different ways.
  • the operating mode is determined by the operating personnel. If this decision is made by the plant itself, it is generally dependent on several factors. An essential of these factors is the value for the outside temperature, which is measured by means of the outside temperature sensor 12 and communicated to the system control unit 9. At outside temperatures that are far above or below the compartment set temperature, the system control unit specifies the corresponding operating mode, after which the switch 5 or the changeover switch 7 is set to K (cool) or H (heat).
  • the transition area in which the outside temperature is close to the target compartment temperature, other factors such as the different compartment temperatures measured in the passenger coach, the specified target values for these temperatures and the temperature in the supply air duct of this passenger coach are included in this decision.
  • a suitable logic is installed in the system control unit, which determines which operation is the more economical, for example that with the lower energy consumption. This logic additionally, in particular in this critical temperature range, avoids unnecessary or frequent switching of the system from heating to cooling operation and vice versa.
  • compartments do not necessarily have to be physically separate from one another, but can also be vehicle areas which are essentially air-conditioned independently of one another, so that different temperature requirements can also be taken into account within a single interior.
  • this invention is not limited to passenger coaches, but can be applied to vehicles of all kinds, in particular also to tram / subway vehicles, buses or other vehicles with one or more compartments or vehicle areas.
