Definitions

  • the invention relates to a cooling module, in particular for the cooling of outside air for decentrally disposed ventilation systems.
  • Ventilation systems may be established in various ways. For instance, many systems are built as central ventilation systems equipped with a set of air channels which convey the outside air into the rooms, and remove the spent exit air from the rooms. This type of ventilation systems makes it necessary to provide many and long air channels which result in pressure drop, and the system must therefore be dimensioned such that it can supply all the rooms with fresh outside air, and so that it can also compensate for the pressure drop through the channels. Dimensioning of such systems is frequently difficult, and, as a result, there are examples of systems having an inferior function in the form of poor ventilation or a high noise level.
  • Ventilation systems are frequently equipped with heat recovery facilities, such as heat exchangers. This makes it possible to extract heat from the exit air and to supply this heat to the fresh outside air.
  • heat exchangers may be constructed in several ways, where passive cross-flow or counter-flow heat exchangers frequently occur.
  • the heat exchangers may also be equipped with liquid coupled recovery faces.
  • Ventilation systems for an entire building may also be composed of decen- tral ventilation systems, which are arranged in each of the rooms in which ventilation is desired.
  • the decentral systems are very compact, and the capacity is adapted to the room.
  • Decentral ventilation systems may also be equipped with heat exchangers for heat recovery.
  • An example of such a system is shown on the applicant's homepage www.airmaster.dk, where it is described in an installation and operation manual designated Airmaster Il 300.
  • the shown system is equipped with a counter-flow heat exchanger for heat recovery, but also with a bypass valve, whereby the heat recovery may be disconnected, and the fresh air is sent directly into the room.
  • This function is useful in particu- lar in case of a great incident solar radiation, or when the outside air temperature is high.
  • the shown system cannot cool the outside air to a de- sired temperature before injection into the room.
  • Air condition systems are also frequently constructed as decentral systems to be mounted in a room in which they can either heat or cool injected air. Air condition systems are provided with a cooling circuit which may be switched for heating or cooling. Such systems are frequently mounted on an external wall or in connection with a window. For reasons of noise and space, the ventilator and the compressor of the cooling system are mounted externally in a box, and, internally, an injection ventilator is disposed behind a grating. Noise nuisances frequently occur both outside and inside.
  • a cooling module which comprises a housing provided with a cooling circuit having components for the filtration and cooling of outside air, and in that the cooling module is configured to be arranged indoors and to be coupled together with and to cooperate with a decentral ventilation system likewise arranged indoors, and in that the cooling circuit and the air flow through the cooling module are controlled by the ventilation system.
  • a supplier achieves the advantage of simultaneously being able to increase the possibilities of subsequent mounting at existing customers, to increase the flexibility in case of new projects and to be able to offer the user better comfort in the room by cooling the outside air in a simple and financially advantageous manner.

  • the housing is additionally provided with a set of mounting plates, which are fixedly connected with each other, and all the components of the cooling modules are secured to these plates, said plates standing on the bottom of the housing, it is ensured in case of a repair or service job that all the components may be taken out at the same time by dismounting the bottom.
  • the cooling system is composed of the stated components, all of which are standard components for the manufacture of cooling systems, an efficient, thoroughly tested and financially attractive solution is achieved.
  • the air flow through the cooling module is determined by the speed of rotation of the injection and exhaust ventilators of the ventilation system, it is ensured that the air flow is determined by the ventilation need, and also a cooling module saving is achieved, because no ventilator for the operation of the cooling module has to be incorporated.
