Definitions

  • the invention relates to a device for easier defrosting of refrigeration Apparatus, in particular air coolers, according to the preamble of patent claim 1 such a device is known for example from DE 31 18 600 A1.
  • Air coolers are often used in rooms with temperatures below 0 ° C. During the Operation of such air coolers leads to ice accumulation on the heat transfer surfaces of the Heat exchanger. This ice formation has a negative effect on the heat transfer or Heat transfer coefficient, so that the overall heat transfer is deteriorated. Therefore, it is common practice to use the heat transfer surfaces, i.e. the heat exchanger surfaces, at predetermined intervals, for example by supplying electrical energy, gas or Warm water to thereby heat the ice formed on the heat transfer surfaces melt down. The fans are switched off during such a defrost phase. Despite If the fans come to a standstill, larger amounts of heat are applied during the defrosting phase given the environment.
  • the air circulation is particularly formed intensely on the side of the air cooler on which the one heated during the defrost phase Heat exchanger block is ultimately obtained in such an operation in High energy losses due to the unused amount of heat. It can also cause steam vapor formation and to a frosting in the immediate vicinity of the air cooler and at the air cooler come yourself.
