Novel subcooled tube group assembly

Abstract

The invention relates to a system pipeline piece for air conditioners, in particular to a novel subcooled tube group assembly. The novel subcooled tube group assembly includes a capillary tube (1), a filter (2) and a capillary tube connecting tube (3), the filter (2) and the capillary tube connecting tube (3) being connected respectively to two ends of the capillary tube (1), a section of transition tube (4) being arranged between the capillary tube (1) and the filter (2), the transition tube (4) being provided with a raised point (4-1) and a recessed point (4-2), the raised point (4-1) being used for mounting and position defining between the transition tube (4) and the filter (2), the recessed point (4-2) being used for mounting and position defining between the transition tube (4) and the capillary tube (1); another end of the filter being provided with a filter connecting tube (5); the capillary tube (1) being fixed into a loop shape through a wiring harness (6); the capillary tube connecting tube (3) and the filter connecting tube (5) having different diameters. The novel subcooled tube group assembly herein has a simple structure design and the capillary tube connecting tube (3) and the filter connecting tube (5) with different diameters can prevent staff from inserting in an opposite direction.

Description

technical field [0001] The invention relates to a system pipe fitting for an air conditioner, in particular to a novel supercooled pipe group assembly. Background technique [0002] The refrigeration system is mainly composed of a condenser, a compressor, an evaporator, and a supercooling tube group. The supercooling tube group is a throttling element. Low pressure refrigerant. In the prior art process tube group design process, there are the following disadvantages: [0003] 1. The outer diameter of the tube connected to the capillary and the filter is the same, and both forward and reverse can be inserted normally. If the operator is not familiar with it or misuses it, it may be inserted in reverse, because the supercooled tube group is inserted in reverse, and the exhaust temperature will rise. , During the random test, it was found that the cooling operation shut down, while the temperature was low during the heating, and the heating effect was also very poor. [0004...

Problems solved by technology

[0003] 1. The outer diameter of the tube connected to the capillary and the filter is the same, and both forward and reverse can be inserted normally. If the operator is not familiar with it or misuses it, it may be inserted in reverse, because the supercooled tube group is inserted in reverse, and the exhaust temperature will rise. , during random testing, it was found that the cooling operation shut down, while the heating temperature was low, and the heating effect was also very poor.

[0004] 2. Because the inner diameter of the capillary is too thin (for example, the outer diameter is 2.7, the inner diameter is 1.4), it is impossible to make a positioning convex, so that when the manufacturer produces the capillary, the insertion depth of the filter cannot be controlled. , will deform the top of the filter, forming a half blockage, the cooling and heating effect will decrease, and it is not easy to find (it is good and bad during operation)
