Water film type air conditioner and indoor heat exchanger used thereby thereof
Technical field
The present invention relates to field of air conditioning, be specifically related to a kind of water film type air conditioner and indoor heat exchanger used thereby thereof.
Background technology
Conventional at present various air-conditioning units, room air cooling all adopt copper pipe cover aluminium finned heat exchanger, and the interior unit of composition is common as family expenses wall mounted machine, clothes closet machine, commercial fan coil etc.During air-conditioning unit refrigeration work, cold-producing medium is flow evaporation in the pipe of copper pipe cover aluminium finned heat exchanger, and room air then skims over the pipe fin outside and obtains cooling; Existing structure has following defective:
1, in most cases, the room air dew point is lower than the heat exchanger surface temperature, causes the condensation phenomenon, and dust will incorporate in the moisture film in the air at this moment, because aluminium fin gap is too small, flow rate of water flow is too slow, very easily causes dirt accumulation, influences the serviceability of air conditioner;
2, dirt accumulation is between fin, and space therebetween is little, cleans and safeguard all inconveniences;
3, the dirt deposition is present between aluminium fin slit, adds humidity, accumulates harmful bacteria easily, and the room IAQ causes anxiety;
4, behind the traditional air conditioner of installing, the cool cycles of room air is interior circulation, can't exchange with outdoor air easily, and the indoor room air quality is poor, and the cost that drops into when introducing outdoor new wind is big;
5, for traditional air-conditioning, if will use air-conditioning simultaneously, need need install a typhoon coiler in each room at least in a plurality of rooms, deployment cost is higher.
Summary of the invention
The object of the present invention is to provide a kind of water film type air conditioner and indoor heat exchanger used thereby thereof, the present invention has the air self-cleaning function, and air quality is good, and is easy to maintenance, and when installing air-conditioning simultaneously in a plurality of rooms, its deployment cost is low.
