Title:
MICRO-CHANNEL EVAPORATOR AND AIR-CONDITIONING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/019828
Kind Code:
A1
Abstract:
Disclosed are a micro-channel evaporator and an air-conditioning system, wherein same can reduce production costs and improve the energy efficiency of refrigeration. The micro-channel evaporator comprises: at least two flat tube groups (10) located at different positions where air volumes are different in an air-conditioning system, each of the flat tube groups (10) comprising a liquid inlet collecting tube (11), a liquid outlet collecting tube (12), and a group of flat tubes (13) connected between the liquid inlet collecting tube (11) and the liquid outlet collecting tube (12), with distribution tubes (14) being inserted into the liquid inlet collecting tube (11), and the distribution tubes (14) being axially provided with several through holes; a distributor (20), comprising a liquid inlet (21), a liquid outlet (22) corresponding to each of the flat tube groups (10), and capillary tubes (30) respectively corresponding to the at least two flat tube groups (10), with each of the capillary tubes (30) being used for connecting the distribution tube (14) of the flat tube group (10) corresponding thereto to the liquid outlet (22); and a water pan (40) located at the bottom of the at least two flat tube groups (10), wherein the capillary tubes (30) corresponding to different flat tube groups (10) have different sizes selected according to the difference of air volumes at the positions where the flat tube groups (10) are located.
