Definitions

  • the invention relates to a two-channel air conditioning for air conditioning a number of spaces according to the specified in the preamble of claim 1.
  • Spaces in particular of buildings, may, for example, due to their orientation to the north or south, be aligned with prevailing wind directions or due to the devices located in the rooms, different heat and cooling loads. Therefore, single-channel air conditioners and zone air conditioning systems are not always suitable for air conditioning multi-room buildings, since the air to be conditioned in these cases must be introduced in different states in the rooms to be air-conditioned.
  • a mixing device is incorporated in the mixing boxes, which includes a pneumatic actuator, a cooperating with the cold air duct cold air valve and a cooperating with the hot air duct hot air valve.
  • a pneumatic servomotor By a pneumatic servomotor, the valve positions are coupled together. If the valve to the warm air duct is opened to 30%, the valve to the cold air duct is also opened to 70%. This always results in an opening value of 100%, whereby the amount of air that is conveyed through the mixing box always remains the same.
  • the mixture of hot and cold air is controlled while maintaining the amount of air.
  • rooms with maximum cooling load only receive cold air - the valve to the cold air duct is 100% open and at the same time the valve is 0% open to the hot air duct - and rooms with maximum heating only warm air - the valve to the hot air duct is 100% open and at the same time the valve to the cold air duct 0% open - and rooms with partial load a mixture of cold and warm air with corresponding openings of the two valves.
  • Such air conditioning is, for example, from the book Recknagel, Sprenger, Schramek: Paperback for Heating and air conditioning, Kunststoff and others, Oldenburg Industrieverlag, 2003, pages 1093-1096 known.
  • the DE 35 09 621 C2 , the DE 33 07 116 A1 , the DE 1 454 635 A , the DE 1 454 615 A , the DE 21 35 934 A and the CH 576 609 A each relate to a two-channel air conditioning system described above.
  • GB 2 235 551 A discloses a two-channel air conditioning system according to the preamble of claim 1. Ventilation systems result from the DE 1 580 983 A as well as the DE 198 47 504 C1 , A disadvantage of the two-channel systems mentioned above, that in the summer as well as in winter both in the hot air duct and in the cold air duct permanently warm air and cool air must be maintained. Thus a register in a channel is always activated.
  • the invention is therefore based on the object to form a two-channel air conditioning on such that the flexibility is increased.
  • the conditions are to be created in order to reduce energy consumption considerably, and in particular to allow an adaptation of existing two-channel air conditioning systems to the invention.
  • the invention is based on the finding that the coupling of the valve devices does not meet the individual air conditioning needs in the rooms to be air-conditioned, thereby resulting in waste of energy.
  • decoupling the valve device this problem can be solved in a simple manner. Now it is possible, if necessary, to direct the maximum supply air quantity from one supply air duct as well as the maximum supply air volume from the other supply air duct into a room to be conditioned. A quick adaptation to the desired conditions and a high degree of flexibility is thereby achieved.
  • valve means are formed independently of each other so that the amounts of air from the respective supply air ducts to the individual rooms to be air-conditioned are independently adjustable.
  • the valve device is in each case designed and controlled so that only one of the supply air ducts can be connected to the air inlet device of a room to be air-conditioned.
  • one of the variables pressure, temperature, humidity, density in each supply air duct, independent of the respective size in the other supply air duct, is to be used as a guide parameter for the control / regulation. This further improves the flexibility and the possibility of optimizing the system.
  • the two-channel air conditioning system cooperating with the temperature controllers of the rooms to be air conditioned circuit, which is connected to the temperature sensors in the supply air ducts, the temperature sensors in the rooms to be air conditioned and arranged in at least one supply air duct cooling or heating register, wherein the circuit a control signal which opens the cooling or heating register only emits if the temperature in at least one supply air channel for cooling or heating the rooms to be air-conditioned is insufficient in connection with the delivered air volume.
  • the pressure in the supply air ducts is regulated as a function of the required air quantities via the flaps forming the valve device and / or an intake air motor.
  • each supply air duct may have a heating and / or cooling coil or, alternatively, the one supply air duct may comprise a heating coil and the second supply air duct may comprise a cooling coil.
  • the cooling and heating registers of the supply air ducts are independently adjustable over a predetermined temperature range.
  • the minimum supply air temperature in the supply air ducts essentially corresponds to the minimum temperature of the system with which it does not suffer any damage, for example 12 ° C.
  • the amount of air supplied to the individual supply air ducts varies independently of each other.
  • the supply air quantity can be determined for the rooms or room zones to be air conditioned as a function of the difference between the temperature in the room to be air-conditioned (T room ) or the room zone to be conditioned and the preset temperature / setpoint (T room setpoint ) as well as the supply air temperature vary.

About the individual sensors, the temperature in the room 44, 46, 48 regulated. In the control loop, a corresponding desired value is specified for the respective room. In this case, the cooling coil 32, 58, the heating coil 34, 60, and the humidifier 36, 62 in the respective supply air duct 20, 22 only activated when needed, the temperature for cooling or heating the room to be conditioned or the degree of humidification in at least one the supply air ducts 20, 22 is insufficient. As a rule, the air inlet 52 in the space 44, 46, 48 to be conditioned is connected to only one supply air duct 20 or 22.

This is designed so that, depending on the requirements, only one of the supply air ducts 20, 22 is connected to the air inlet 52 in the air-conditioned spaces 44, 46, 48. In addition, the air quantity from the respective supply air duct 20, 22 is controlled independently of one another via the flaps 54 and 72.

  • the heating register 60 of the second supply air duct 22 is opened.
  • the outside temperature is - 20 ° C.
  • All rooms 44, 46, 48 have an increased heating demand. Now it may be that the heating power of the second supply air duct 22 with the heating register 60 therein is not sufficient to heat the rooms 44, 46, 48.
  • the first supply air duct 20 is opened, in which the flaps 54 and 24 open and the heating register 34 also opens.

  • the temperature value of the temperature sensor 38 in the first supply air duct 20 and the temperature value of the temperature sensor 64 in the second supply air duct 22 for opening and closing the respective associated flap 54,72 in the first or second supply air duct 20 or 22 used. If cooling or heating takes place in both supply air ducts 20, 22, the flaps 54, 72 assigned to the supply air ducts 20, 22 are respectively opened or closed proportionately. If both channels have the same supply air temperature, the flap positions of the flaps 54, 72 for the respective space 44, 46, 48 are the same. That if there is a high demand for heating / cooling both flaps are 100% open, if the heating demand / cooling requirement is essentially covered, the flaps are open, for example, only up to 30%. The flap openings may differ from room to room.
  • the supply air ducts can also be activated and deactivated for humidification and dehumidification.
  • valve means 54, 72 are set independently. This results in far-reaching possibilities. For example, it is now possible that in the room to be air conditioned, the maximum possible supply air from the one Channel as well as from the other channel is initiated, for example, to allow rapid warm-up or cooling. As a result, the flexibility of the system but also the reaction rate is significantly increased.
  • one of the variables pressure, temperature, humidity, density in each supply air duct is adjustable independently of the respective size in the other supply air duct.
  • a further aspect is also that by the decoupling of the valve means a supply of at least one supply air duct 20, 22 with a further, upstream single-channel system is possible. About the independently adjustable valve means 54, 72 occurring pressure fluctuations can be compensated.
