Regulating system provides institute's calorific requirement, to offset indoor environment thermic load.
Central air conditioner system transmits hot-air in cold air and suction room eventually by air hose, thus air hose occupy it is whole
Most volumes of a central air conditioner system, and since air hose entirety path is longer, it is difficult to it is integrally formed, it usually needs pass through
Several air hoses are spliced to complete pipe laying.
During air hose splices, the connection of adjacent air hose is usually placed on by sealing elements such as sealing ring, gasket seals
Place is simultaneously clamped by adjacent air hose to realize sealing, although by clamping so that sealing element deformation and air hose end
It is close to, but the sealing element place of being extruded will be made to be chronically at stress in this way and then generate fatigue damage, influences sealing element
Service life, there are also improve space.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of air-conditioning system installation method, have
The long advantage of seal durability.
To achieve the above object, the present invention provides the following technical scheme that
A kind of air-conditioning system installation method, comprising the following steps:
(1) air-conditioner host is installed；
(2) air hose pre-processes, specific as follows:
In air hose both ends welded flange, the flange surface setting accommodates the holding tank of sealing element, and the holding tank is along method
Orchid circumferentially extending and head and the tail connection；
(3) it is laid with air hose；
(4) air hose connects, specific as follows:
Interior one connecting tube of grafting simultaneously of adjacent air hose, unvulcanized sealing element is then put into the holding tank, connects phase
Then the flange of adjacent air hose heats the air hose end to connect adjacent air hose and clamp unvulcanized sealing element so that it is described not
Vulcanize sealing element by thermal softening and crosslinking curing forms sealing element；

Increase the attachment force of sealing element and metal after vulcanization by the way that cobalt salt is added, and then improves sealing element and flange 2
Connective stability, to improve leakproofness.
Since the volume of sealing element is greater than twice of the volume of 21 inner space of holding tank, when guaranteeing that adjacent flanges 2 connect
To the squeezing effect of unvulcanized sealing element 3, at the same flange 2 connect so that 3 part spillage containment slot 21 of unvulcanized sealing element and with
The connection of 2 joint face of flange, further increases sealing effect.
All air hoses 1 are wound to heat by a heating wire 5, so that heating while carrying out, and easy to operate.
By being wrapped circumferentially around heat preservation member 4 along flange 2, heat loss at flange 2 is reduced using heat preservation member 4, it preferably will be hot
Amount acts on unvulcanized sealing element 3 so that 3 elevated temperature cure of unvulcanized sealing element, improves curing efficiency, while utilizing after powering off
Waste heat continues to keep the vulcanization reaction of sealing element, so that vulcanization reaction is more abundant.
By carrying out rough surface processing to 21 inner surface of holding tank, so that unvulcanized sealing element 3 infiltrates into after being extruded
On pitted skin, and then the connection area of sealing element Yu holding tank 21 is improved, improves connective stability while improving attachment force,
Preferably guarantee airtight effect.
