Definitions

  • the invention relates to a device for sorption-assisted air conditioning of room air, in which outside air is adsorptively dried in an adsorption dryer, the outside air, which has been dried by adsorption and heated in the process, is cooled and fed to the room to be air-conditioned, the exhaust air emerging from this room is heated and flows through the adsorption dryer for regeneration and is discharged as exhaust air, with a cooler which is arranged in a supply air duct between the room to be air-conditioned and a regenerative heat exchanger and is connected downstream of the adsorption dryer in the flow direction of the air.
  • a device for sorption-based air conditioning of rooms is also known from DE 299 15 459.

  • CHP combined heat and power unit
  • the waste heat from the CHP unit also serves to regenerate the adsorption wheel.
  • the object of the present invention is therefore to enable sorption-based air conditioning of rooms in which no water is used for cooling the air and only a small requirement for electrical energy arises.
  • the object is achieved in that the cooler is connected to a cold source which has a medium cold level.
  • the cold source has a cold level above the dew point of the outside air and / or the dried air.
  • the dew point is the temperature below which the water vapor condenses in the air.
  • the cold source preferably has a cold level of 12 to 20 ° C., particularly preferably 14 to 17 ° C.
  • a cold level in these temperature ranges is generally suitable according to the present invention in order to bring about sufficient cooling of the air.
  • the cold source is soil and / or groundwater and / or river water
  • the cooler is connected to the cold source via a heat exchanger, in the case of soil and / or groundwater, for example via a geothermal heat probe.
  • the heat source can be a combined heat and power plant, a gas-water heater, a fuel cell or a solar collector (water or hot air collector).
  • the heat required for heating the exhaust air for the purpose of regenerating the adsorption dryer which is preferably low-temperature heat in a temperature range from 50 to 90 ° C., can be provided, for example, by a combined heat and power plant (CHP).
  • CHP combined heat and power plant
  • the waste heat from the CHP plant is used here.
  • a gas-water heater, solar collectors or fuel cells for this purpose. This makes it possible to largely avoid the use of electrical energy to regenerate the adsorption dryer.
  • the CHP can be a small CHP, so that the device is suitable for decentralized use for air conditioning of defined object sizes. In winter, the waste heat from the CHP can also be used to heat rooms, for example.
