As a result, sterilization of the indoor heat exchange (20) is performed, which is advantageous in suppressing the growth of bacteria in the indoor heat exchange (20).
  • FIG. 7 is a schematic diagram showing the configuration of the air-conditioning apparatus according to Embodiment 4 of the present invention.
  • the difference from the third embodiment is that the condensed water generated in the indoor heat exchange (20) is stored in the storage tank (63) and reused as cleaning water. Parts are denoted by the same reference numerals, and only the differences will be described.
  • the condensed water in the outdoor heat exchanger (51) and the condensed water generation unit (70) is stored as it is in the storage tank (63), whereas the condensed water in the indoor heat exchanger (20).
  • the drainage route is switched. [0093]
  • the condensate storage operation of the indoor heat exchanger (20) will be described below.
  • the condensed water generated in the indoor heat exchanger (20) is recovered by a drain pan (23), and is discharged into a drain pipe.
  • the drain pipe (24) is branched into two in the middle of the pipe line, and the drain direction of the condensed water is switched based on the amount of washing water in the storage tank (63).
  • the drain switching valve (64) provided at the branch point of the drain pipe (24) is a control signal output from the float switch (65) for measuring the water level in the storage tank (63). It is designed to switch based on. That is, when the water level in the storage tank (63) is lower than the specified value, it is determined that the amount of water in the storage tank (63) is insufficient, and the drain switching valve (64) is switched to Allow the condensate (20) to flow into the storage tank (63).
  • the condensed water in the indoor heat exchanger (20) is filtered through the filtration filter (66) and then stored in the storage tank (63).
  • a cleaning switching valve (67) is provided in the middle of the water conveyance pipe (61). This cleaning switching valve (67) supplies water that has been sucked up and raised from the storage tank (63) by the water transfer pump (62) to the indoor heat exchanger (20) side, or the indoor heat exchanger (20 ) From the filter cleaning direction that is opposite to the direction in which the condensed water passes through the filtration filter (66) so as to pass the cleaning water through the filtration filter (66).
  • the condensed water discharged from the indoor heat exchanger (20) force contains dust adhering to the indoor heat exchanger (20), so the condensed water is stored in the storage tank (63).
  • the force that removes dust with the filtration filter (66) in advance If left as it is, the filtration filter (66) may be clogged and the condensed water may not flow.
  • the filtration filter (66) needs to be cleaned by detecting the force of detecting that a predetermined time has passed by the timer or the degree of contamination of the filtration filter (66) with a sensor or the like. If this happens, switch the cleaning switching valve (67) and use the water transfer pump (62) By cleaning the raised wash water by supplying side force in the filter cleaning direction of the filter (66)
  • the dust adhering to the filter (66) is removed so as to maintain cleanliness.
  • a plasma discharge unit (68) for supplying cleaning water is provided.
  • the condensed water generated in (20) is stored in the storage tank (63), and the condensed water stored in the storage tank (63) is supplied to the indoor heat exchanger (20) as washing water. ) Can be reused as washing water.
  • the present invention provides a highly practical effect that the indoor heat exchanger can be cleaned even during heating operation in which condensed water is not generated in the indoor heat exchanger. Therefore, it is extremely useful and has high industrial applicability.

Abstract

La poussière en suspension dans l'air est chargée par une unité d'ionisation (25) et la poussière chargée se colle dans un échangeur de chaleur intérieur (20). Pendant l'opération de refroidissement, la poussière est éliminée par de l'eau condensée générée dans l'échangeur de chaleur intérieur (20). Par ailleurs, pendant l'opération de chauffage, l'eau condensée générée dans un échangeur de chaleur extérieur (51) sert d'eau de lavage fournie par une unité de distribution d'eau (60) à l'échangeur de chaleur intérieur (20) afin d'éliminer la poussière.
