Definitions

• the invention is a device and a method for cleaning of a climate conditioner or a heat pump indoors part/heat exchanger for dust .
• JP 07190683 is an appliance for cleaning of wall mounted, indoor heat exchangers.
• the method used relies on chemical cleaning agents without compressed air or mechanical suction.
• the amount of chemical cleaning agent in this method will be substantial, and the danger of use of unsuitable cleaning agents that may cause damage to the electronic part of the heat exchanger is considered to be appreciable.
• the appliance is not form stable and is not suitable to create underpressure .
• JP 2001027498A is an appliance for cleaning of indoor heat exchangers.
• the method used relies on the use of water. A water pressure arises when the appliance (the bellows) is forced against the heat exchanger and which then leads the water through the heat exchanger.
• this method relies on use of water, it is most probably only intended for cleaning of heat exchangers that do not contain electric or electronic components, which a modern indoor part for a heat pump does, as these have this integrated under the same cover.
• JP 59030000A is an appliance for internal cleaning of the cooling pipes in a heat exchanger, popularly called "pipe flushing" and has no relation to cleaning of the heat exchanger outside ribs and/or between these.
• US 6305393Bl is an appliance for internal cleaning of the cooling pipes in a heat exchanger, popularly called "pipe flushing" and has no relation to cleaning of the heat exchanger outside ribs and/or between these.
• the object of the invention is to remedy or reduce at least one of the prior art drawbacks, or at least to obtain a useful alternative to prior art.
• the invention deviates substantially from all the up to now known methods for cleaning of the indoor part of the climate conditioner as it utilises:
• An enclosure box is placed on the outside of an indoor part as a temporary airtight encapsulation abutting a wall.
• the enclosure box is made of a transparent material to be able to have a full view of and control with the process up to the point when the air in the enclosure box is clean and the indoor part free of dust.
• the enclosure box is made of a form stable material because it is to withstand an underpressure.
• the enclosure box is supplied with air having 8-12 bar pressure, as the air is led through a nozzle/compressed air pipe having an opening and closing valve giving a high pulsating air speed and small airflow.
• the dust comes loose in the indoor part and is forced out into the enclosure box and further to a suction device.
• the suction device will suck out more air than is blown in. An underpressure will then arise in the enclosure box, and this condition will dominate during the whole process as a balanced pressure/suction function.
• Fig. 1 shows a cross-section through an indoor part where a device according to the invention is connected
• Fig. 2 shows in perspective an enclosure box setting about being arranged on the indoor part after the front cover is removed.
• An enclosure box 6 is arranged on the outside of an indoor part 1 after the front cover 2 and filter 3 have been removed from the indoor part 1 as shown in fig. 2.
• the enclosure box 6 is provided with a gasket 7 being squeezed against a wall behind such that dust tightness around the indoor part 1 is formed.
• the enclosure box 6 is hung off the upper rear edge of the indoor part 1 by means of a fastener 12 as shown in fig. 1.
• blowing slots 8 being of equal length to the width of the indoor part 1 are arranged and sealed with two opposing bulb gaskets 9, so that the blowing slots 8 becomes tight and that dust does not come out through them.
• a compressed air pipe 10 is led through the blowing slot 8 and directed toward or led in through the indoor part fan and radiator fins inside the indoor part 1, for in this way to loosen and transport dust out via a suction device 14 shown in fig. 1.
• a suction pipe stub 11 there is in the left hand side of the enclosure box 6 a suction pipe stub 11. This is arranged remote from the indoor part 1 electronics 5, which in the example shown is arranged on the right hand side so that the dust is led away from the electronics and toward the suction pipe stub in the bottom where it is evacuated.
• the task of the enclosure box 6 is as mentioned to get all the dust led out of the climate conditioner indoor part 1 without the dust whirling out into the room during the process.
• the dust is so fine that it has passed through the filters and has settled inside the indoor part 1.
