Definitions

  • heat exchangers are used so that the warm exhaust air is not used unused outside.
  • the recovery of heat from the warm exhaust air is achieved by giving off heat to the fresh air introduced through the heat exchanger, for example in stables or industrial halls. This reduces operating costs by up to 60%.
  • the preheated fresh air supplied by the heat exchanger is then brought to the operating temperature with a small amount of heating.
  • Heat exchangers with metal or glass plates are known which are used in a housing made of sheet steel.
  • the plates are installed in the housing at a short distance from one another and in parallel in a vertical manner.
  • the warm exhaust air and the cold fresh air are conducted separately between the glass plates in a cross flow so that the exhaust air e.g. sideways and the fresh air is supplied from above.
  • the colder air flow takes over the vast majority of the heat present in the other air flow.
  • CH-PS 611 701 describes a heat exchanger with tubes made of borosilicate glass.
  • the glass tubes are arranged vertically close together in a metal frame and have a diameter of approximately 13 mm. Here the exhaust air is led through the gaps between the pipes and the fresh air through the interior of the pipes.
  • Such a heat exchanger should be usable for operating temperatures higher than 30 ° C.
  • the invention had for its object to provide a heat exchanger made of such a material that has good stability, is heat-resistant and insensitive to cold and can work in negative pressure.
  • the manufacturing costs of such a material should be kept significantly lower than those of the known materials.
  • Each such double wall plate advantageously has a thickness of at most 15 mm and the double wall plates are accommodated in the heat exchanger such that the distance between two adjacent double wall plates is at most 15 mm.
  • the plastic double-wall plates used as guide plates for exhaust and fresh air in the heat exchanger are heat-resistant up to 140 ° C and insensitive to cold down to -40 ° C. They have excellent stability and can absorb a vacuum of up to 50 mm water column without loss of performance. Such double-wall sheets are customary and inexpensive.
  • the thickness of the individual double-wall sheets 1 is 4 to 15 mm.
  • the double-wall sheets are vertically assembled into a block.
  • the distance between two adjacent double-wall sheets 1 next to one another also amounts to 4 to 15 mm, depending on the thickness of the double-wall sheet 1.
  • the cold fresh air is supplied through the spaces delimited by the webs 1a of the web double plates 1.
  • the warm exhaust air which has a temperature of 20 ° C in cattle houses and is full of ammonia and dust, is combined by the gaps between the individual out other parallel web double plates 1 out. If the cold fresh air has a temperature of about 0 ° C and the exhaust air has a temperature of about 20 ° C, the colder fresh air takes over most of the heat in the exhaust air as it flows through the heat exchanger.
  • the heated fresh air can have a temperature of around 10 ° C when it exits the heat exchanger.
  • the efficiency here is about 50%: depending on the temperature gradient, air humidity, etc., it can be increased by up to 85%.
  • the web double plates 1 are accommodated in a housing 7.
  • this housing 7 consists of two side walls 4, an upper wall 6 and an abbreviated lower wall 5.
  • the warm exhaust air exits at one end of the housing 7, which is from the lower wall 5 is not covered, in the counterflow heat exchanger and then flows through the gaps between the individual web double plates 1 in counterflow to the fresh air and emerges on the other end of the housing 7 as cold exhaust air, which end is also not covered by the lower wall 5.
  • the exhaust air flow is generated by an exhaust air fan 8. The cold exhaust air is then released outside.
  • the cold fresh air is passed through a supply air fan 9 in a forced flow through the spaces delimited by the webs 1a, where it takes over the heat from the exhaust air.
  • the heated fresh air is blown into the interior of the housing 10.
  • This counterflow heat exchanger A can be used at an exhaust air temperature of approx. 20 to 30 ° C and a fresh air temperature of down to minus 12 0 C, whereby no ice forms in the exhaust air part.
  • the cross-flow heat exchanger B shown in FIG. 4 can be used at an exhaust air temperature of approximately 20 to 30 ° C. and a fresh air temperature of down to minus 7 ° C.
  • ice forms much faster in the exhaust air section than in the counter-flow heat exchanger A.
  • the housing 7 has only the side walls 4, which are connected to one another by closing angles, so that the exhaust air through the Heat exchanger B can flow freely from the bottom to the top.
  • the outer walls of the double wall plates 1 of a countercurrent heat exchanger A are provided on their upper edges with plastic tubes 2 with holes 3, which are used for spraying water on the outer walls of the double wall plates 1.
  • nozzles (not shown) are provided for spraying outer walls of the web double plates 1.
  • the water sprayed onto the outer walls of the double-wall sheets 1 in order to clean them from various dirt deposits goes away as condensed water with the exhaust air or is channeled.
