Abstract
This invention relates to one air conditioning machine coolant distribution components, which comprise the following parts: Maintenance valve board with multiple holes on one side of the outdoor shell; multiple maintenance valves and electrical expansion valves located with equal distance by parallel through maintenance valve board; T shape tube with two exit facing to top and down connected to the coolant along level direction from indoor machine; C shape coolant distribution tube connected to the maintenance valve along level direction relative to the two ends entrance.
Description
Technical field
The present invention relates to a kind of air-conditioner outdoor unit, particularly relate to a kind of coolant dispensing assembly that can make the uniform air-conditioner outdoor unit of cold medium flux in each indoor set.
Background technology
Usually, air-conditioner is a kind of device that makes its inner refrigerant carry out the kind of refrigeration cycle be made up of compression process, condensation process, expansion process and evaporation process.In air-conditioner, the refrigerant that becomes high-temperature high-pressure state through overcompression can dispel the heat to the outside in condenser, and when flowing through expansion valve, significantly reducing its temperature and pressure, this low temperature, low pressure refrigerant can absorb heat when flowing through evaporimeter then, flow back to compressor at last again.Wherein, compression process, condensation process and expansion process are to carry out in the off-premises station of air-conditioner, and evaporation process then is to carry out under the effect of blowing fan in indoor set and evaporimeter.Fig. 1 is the not multi-split air conditioner off-premises station structure side view of mounting portion housing of prior art.Fig. 2 is the multi coil structural perspective that the maintenance valve links to each other in the coolant dispensing assembly with Fig. 1.As shown in Figure 1 and Figure 2, the multi-split air conditioner off-premises station of this prior art comprises that mainly inside is equipped with the housing 1 of main devices such as compressor, condenser and outdoor fan; With a side that is installed in housing 1 and refrigerant can be offered the coolant dispensing assembly 2 of off-premises station or indoor set.Described coolant dispensing assembly 2 mainly comprise on the side that is arranged on outdoor shell 1 and above be formed with the repair valve plate 3 of a plurality of perforates; Run through the perforate of repair valve plate 3 and equidistantly be set in parallel in a plurality of maintenance valves 4 and electric expansion valve 5 on the repair valve plate 3; And by the person in charge 6 who vertically is provided with a plurality of be responsible for 6 vertical link to each other and with keep in repair the multi coil 8 that arm 7 that valve 4 joins is formed.As mentioned above, because the maintenance valve 4 that is arranged on the repair valve plate 3 equidistantly be arranged in parallel, therefore can be when entering multi coil 8 from the refrigerant of indoor set former thereby concentrate on arm 7 places of its downside because of the pressure of refrigerant in managing and gravity etc., promptly its flow of bottom the closer to multi coil 8 is big more, will make the cold medium flux that enters each maintenance valve 4 inhomogeneous like this, consequently the refrigeration of each interior space or heating effect have very big difference.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of coolant dispensing assembly that makes the uniform air-conditioner outdoor unit of cold medium flux in each indoor set.
In order to achieve the above object, the coolant dispensing assembly of air-conditioner outdoor unit provided by the invention comprise on the side that is arranged on outdoor shell and above be formed with the repair valve plate of a plurality of perforates; Run through the perforate of repair valve plate and equidistantly be set in parallel in a plurality of maintenance valves and electric expansion valve on the repair valve plate; Inlet is connected with refrigerant pipe along continuous straight runs from indoor set, and two outlets respectively towards upper and lower to T shape manage; Vertically be provided with, and two end entrances link to each other with two outlets of T shape pipe respectively, then be formed with on the straight tube relative with two end entrances a plurality of along continuous straight runs settings and can with the C shape refrigerant distributing pipe that keeps in repair the arm that valve be connected.
Described T shape pipe and C shape refrigerant distributing pipe connect into annular.
Rounding off should be adopted in the bending place of described C shape refrigerant distributing pipe.
The coolant dispensing assembly of air-conditioner outdoor unit provided by the invention is that the multi coil with straight tube-like makes the ring pipe be made up of T shape pipe and C shape refrigerant distributing pipe into, so just can avoid refrigerant from indoor set former thereby concentrate on the multi coil downside that vertically is provided with because of pressure and gravity etc., thereby can make refrigerant evenly and reposefully offer the maintenance valve that is connected with C shape refrigerant distributing pipe, the temperature of respectively freezing or heating the space is consistent.
Description of drawings
Be elaborated below in conjunction with the coolant dispensing assembly of the drawings and specific embodiments to air-conditioner outdoor unit provided by the invention.The parts identical with prior art use identical symbol, and omit its explanation of carrying out.
Fig. 1 is the not multi-split air conditioner off-premises station structure side view of mounting portion housing of prior art.
Fig. 2 is the multi coil structural perspective that the maintenance valve links to each other in the coolant dispensing assembly with Fig. 1.
Fig. 3 is T shape pipe and a C shape refrigerant distributing pipe structural perspective in the coolant dispensing assembly provided by the invention.
The specific embodiment
As Fig. 1, shown in Figure 3, the coolant dispensing assembly of air-conditioner outdoor unit provided by the invention comprise on the side that is arranged on outdoor shell 1 and above be formed with the repair valve plate 3 of a plurality of perforates; Run through the perforate of repair valve plate 3 and equidistantly be set in parallel in a plurality of maintenance valves 4 and electric expansion valve 5 on the repair valve plate 3; Inlet 10 is connected with refrigerant pipe along continuous straight runs from indoor set, and two outlets 11,12 respectively towards upper and lower to T shape manage 13; Vertically be provided with, and two end entrances 14,15 are continuous with two outlets 11,12 of T shape pipe 13 respectively, and then be formed with a plurality of along continuous straight runs settings on the straight tube 16 relative and the C shape refrigerant distributing pipe 18 of the arm 17 that can be connected with maintenance valve 4 with two end entrances 14,15.Described T shape pipe 13 and C shape refrigerant distributing pipe 18 connect into annular, thus maintenance valve 4 porch that can avoid refrigerant to concentrate on being positioned at the bottom.Rounding off should be adopted in the bending place of described C shape refrigerant distributing pipe 18, can reduce the pressure loss that refrigerant produces because of resistance like this in flow process, thereby can cut down the consumption of energy.When air-conditioner moves, refrigerant from indoor set at first flows into its inside from the inlet 10 of T shape pipe 13, then along upper and lower to the bending after respectively from exporting 11,12 enter two end entrances 14 of C shape refrigerant distributing pipe 18,15, the refrigerant that enters C shape refrigerant distributing pipe 18 will flow into straight tube 16 along the bend pipe at two ends about it, because refrigerant is through repeatedly bending its pressure of back and flow will be tending towards balanced, thereby enter each maintenance from arm 17 and just the problem of maldistribution can not occur during valve 4, thereby the temperature that can make each refrigeration or heat the space is consistent.
