Description of drawings
Fig. 1 is the structural representation of the utility model;
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is explained further details.
Referring to shown in Figure 1, condenser 1 is installed in the top of machine room than distant positions, and indoor set 2 is in machine room, and distance is far away between condenser 1 and the indoor set 2, and the centre is connected by pipeline, and pipeline is made up of tracheae 6 and liquid pipe 7.Recoil is installed on the liquid pipe 7 of condenser 1 front end bends 5, U type trapped fuel curved 8 evenly is being installed on vertical tracheae 6.In the junction of tracheae 6 and indoor set 2 check valve 4 is installed in addition, with the junction of indoor set 2 stop valve 3 is installed also at tracheae 6, liquid pipe 7, so that maintenance.It is middle with indoor set 2 that stop valve 3 is positioned at check valve 4.Wherein tracheae 6 is the pipeline that relative original design pipeline amplified caliber with liquid pipe 7.
Its specific embodiment is following:
In October, 2005, certain IDC data network company New-deployed Network machine room is after the machine room calculation of Heat Load; The refrigerating capacity that certain brand be equipped with to be installed is three of the air conditioner in machine room of 75KW, and this building, machine room place is an office building, and indoor set 2 is installed in 15 layers; Because this building does not design according to the machine room building; Therefore this machine condenser 1 can only be installed in roof platform, and its normal throw is up to 40 meters, through calculating the resistance that the middle various valves of pipeline, elbow etc. cause pipeline; The actual equivalent length of this pipeline one way reaches 60 meters, and the installation parameter of air-conditioning equipment has exceeded the technical specification of producer's regulation.
As shown in Figure 1, distance is far away between condenser 1 and the indoor set 2, and height fall reaches 40 meters, and the actual equivalent length of pipeline one way reaches 60 meters, and the equipment installation parameter has exceeded the technical specification of producer's regulation.In order to guarantee equipment stable operation, must the air conditioning pipe system of overlength be improved.Because the tracheae of overlength 6 can cause resistance excessive with liquid pipe 7, therefore, the caliber of tracheae 6 and liquid pipe 7 is strengthened.According to the design of air-conditioning equipment producer, system pipeline tracheae 6 diameters are φ 28, and liquid pipe 7 diameters are φ 22.Calculate according to technical data, the pipeline configuration is adjusted into: tracheae 6 enlarged diameter of horizontal level are φ 32, and tracheae 6 diameters of upright position are constant, and the enlarged diameter of liquid pipe 7 is φ 25.
Since the pipeline overlength, the also necessary oil return problem of considering compressor.Have part refrigeration lubrication oil during compressor operating and mix with the refrigerant gas of HTHP, be discharged in the system, if the refrigeration lubrication oil of discharging can not get back to compressor or oil return is less, compressor will cause damaging because of oil starvation.Because therefore the pipeline overlength has more refrigeration lubrication oil and stays in the middle of the pipeline of system.
To this, solution one is the additional addition that goes out refrigeration lubrication oil according to Theoretical Calculation, and measure two is in system's tracheae 6 vertical duct; Curved 8 one of every 5-7 meter ampere dress U type trapped fuel, air-flow is through out-of-date because inertia and gravity, meeting of entrained oil mist and flow separation; And deposit stream in U type trapped fuel curved 8, when accumulating to a certain degree, high pressure gas fails to be convened for lack of a quorum and promotes its upwards atomizing; Up to condenser 1, dissolve each other with condensed fluid and to get back to compressor.
The addition of refrigeration lubrication oil is: 1) according to the filling of one way pipeline actual measurement length, 2.5ml/m;
2) according to the volume filling of the curved 8 quantity summations of U type trapped fuel, the U type trapped fuel of φ 16-φ 19 curved 8 approximately adds oiling 30ml, and the U type trapped fuel of φ 22-φ 28 curved 5 is filling 45ml approximately.
In order to prevent that " shwoot " phenomenon takes place in the refrigeration system liquid pipe 7, increased the duty cycle rates of liquid refrigerant in condenser 1, thereby increased degree of supercooling.According to local environment and place; Amplify the configuration model of condenser 1, enlarge the area of dissipation of condenser 1, liquid refrigerant carried out the also corresponding increase of cold area but; So the degree of supercooling of condenser 1 outlet has also increased, and has so just prevented the generation of " shwoot " phenomenon in the refrigeration system.
Because condenser 1 is higher than indoor set 2 and reaches 40 meters; In the shutdown moment of compressor; Liquid refrigerant dynamic pressure before getting into indoor set 2 unit magnetic valves all converts static pressure suddenly to; Make liquid pipe 7 static pressures of indoor set 2 ends apparently higher than the export value of cold doubtful device 1, borrowing this pressure reduction, the liquid refrigerant in the condenser 1 springs back in the tracheae 6 of compressor.Hoard the liquid refrigerant in tracheae 6, when next compressor was opened, it met the rapid vaporized expanding of high temperature gas meeting, stops up tracheae 6, hinders the exhaust of compressor, causes that the high pressure alarm appears in compressor.Therefore, in condenser 1 tracheae 6 porch recoil is installed and bends 5, in case the fault of alarm for high voltage frequently appears in locking system.
At last,, reduce the loss of cold-producing medium,, stop valve 3 one covers have been installed in pipeline and indoor set 2 junctions for convenient later maintenance.
Equipment moves after the installation, and through detecting, the air-conditioner air outlet temperature stabilization is at the 15-17 degree; " shwoot " phenomenon does not take place in liquid pipe 7; Compressor of air conditioner operates steadily, and refrigeration has reached optimum state, and any fault that produces because of installation does not appear in air-conditioning equipment so far.
More than combine accompanying drawing that principal character, advantage and the embodiment of the utility model have been done detailed description; But the utility model is not limited to above-mentioned embodiment; In the ken that affiliated technical field those of ordinary skill is possessed; Can also under the prerequisite that does not break away from the utility model essential feature, make various variations, these variations are all comprised by the utility model.
