Description
Technical field
The present invention relates to the refrigerant Manifold technology field of air-conditioner outdoor unit, is that a kind of to have a secondary damping curved specifically, can reduce the refrigerant pipe of the air-conditioner outdoor unit of a plurality of directions vibrations.
Background technology
Air-conditioner is the hot-air in the suction chamber, makes it to carry out heat exchange with the low temperature refrigerant, and Cryogenic air row is freezed to indoor; Perhaps by opposite effect, the equipment that the interior space is heated.The work loop of air-conditioner is formed by compressor-condenser-expansion valve-evaporimeter.
Air-conditioner comprises and is arranged on outdoor off-premises station (being also referred to as " outside " or " heat release side "), and the indoor set (being also referred to as " indoor " or " heat absorbing side ") that is arranged on interior of building; Be provided with condenser (outdoor heat converter) and compressor in the off-premises station, in indoor set, be provided with evaporimeter (indoor heat converter).
Air-conditioner can be divided into the detachable air conditioner that sets up off-premises station and indoor set separately substantially, is wholely set the integral air conditioner of off-premises station and indoor set.Be in the consideration of aspects such as space and noise are set, detachable air conditioner more is subjected to people's favor now.
Want to be freezed in a plurality of spaces or when heating, can adopt detachable air conditioner with an off-premises station.That is, as a type of detachable air conditioner, air-conditioner can be arranged on have many between on the building of office, can carry out temperature adjustment effectively to each office.Air-conditioner connects several indoor sets on an off-premises station, and several indoor sets are separately positioned on each interior space, can obtain being provided with the effect of several air-conditioners.
Fig. 1 is the structural representation of prior art air-conditioner outdoor unit; Fig. 2 is the structural representation of the refrigerant pipe of prior art air-conditioner outdoor unit.
As shown in Figure 1 and Figure 2, off-premises station 20 comprises the outdoor heat converter 21 that makes outdoor air and refrigerant carry out heat exchange, carry the outdoor fan 22 of the outdoor air of heat exchange, the compressor 23 of compression refrigerant, the outward appearance of off-premises station 20 comprises the chassis 26 that constitutes the bottom surface, 2 supporting seats 27 of 26 the bottom surface horizontal installation of direction forwards, backwards are installed in the shell 28 above the chassis 22 on the chassis.Be formed with combined hole 27a at the two ends of supporting seat 27, respectively in conjunction with support component 30, make off-premises station 20 maintenance levels and be absorbed in the vibration that produces when off-premises station 20 operates in 4 combined hole 27a.
The working cycles loop in air-conditioner when refrigeration is: the expansion valve of the outdoor heat converter of the compressor of HTHP gaseous coolant → provide normal temperature high voltage liquid refrigerants → provide low-temp low-pressure liquid refrigerants → form the gas-liquid separator of the liquid gentle attitude refrigerant of evaporimeter → separation of low temperature state → the provide compressor of HTHP gaseous coolant by the evaporation of liquid refrigerants is provided.
Gaseous coolant flows into compressor 23 from gas-liquid separator (not shown), becomes the gaseous coolant of HTHP through the compression of compressor.The gaseous coolant of HTHP is from the refrigerant pipe 10 of refrigerant inflow entrance 11 inflow air-conditioner outdoor units, and the damping of flowing through then bends 12, flows out from refrigerant flow export 13 to enter into outdoor heat converter 21, carries out heat exchange by outdoor heat converter and outdoor air.
But, there is following not enough point in the aforesaid prior art:
The refrigerant pipe refrigerant inflow entrance and the refrigerant flow export of air-conditioner outdoor unit of the prior art are not in same plane, link to each other by damping is curved between the two, refrigerant is lower than the entry position of refrigerant inflow outdoor heat exchanger from the flow export position of compressor, the damping bending moment is nearer with respect to the refrigerant entry position of outdoor heat converter from the position that compressor flows out from refrigerant, so the cushioning effect that damping bends up mainly acts on the refrigerant pipe and is connected in compressor one side, it is refrigerant inflow entrance one side of refrigerant pipe, damping is curved, and the refrigerant pipe is connected the cushioning effect that a side played with outdoor heat converter also not obvious, and only can reduce the vibrations that in the curved plane, place of this damping, take place, so because the amplitude of compressor vibrations causes refrigerant pipe and being connected of heat exchanger refrigerant porch to rupture greatly easily, cause product to break down during compressor operating or in transportation.
Summary of the invention
The technical problem to be solved in the present invention provides that a kind of to have a secondary damping curved, can reduce the refrigerant pipe of the air-conditioner outdoor unit of a plurality of directions vibrations.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is:
The refrigerant pipe of air-conditioner outdoor unit of the present invention, comprise: refrigerant inflow entrance, refrigerant flow export and damping are curved, refrigerant inflow entrance and refrigerant flow export are not in same plane, link to each other by damping is curved between the two, in refrigerant flow export one side two reciprocal secondary dampings of opening direction being set bends, two secondary dampings are bent with the refrigerant flow export and are in same plane, with the curved antarafacial of the damping that links to each other.
The present invention can also adopt following technical measures:
Described refrigerant pipe is formed in one.
The material of described refrigerant pipe is a copper.
Advantage and good effect that the present invention has are:
The refrigerant pipe of air-conditioner outdoor unit of the present invention is provided with two reciprocal secondary dampings of opening direction in refrigerant flow export one side and bends, and two secondary dampings are bent with the refrigerant flow export and are in same plane, with the curved antarafacial of the damping that links to each other.The curved side of secondary damping is connected in the refrigerant flow export, opposite side links to each other with damping is curved, when compressor operating, two secondary dampings are curved can to reduce the vibrations of coming from the conduction of the refrigerant pipe influence to refrigerant flow export and heat exchanger refrigerant inflow entrance, the vibrations on a plurality of directions have been alleviated, avoided the refrigerant pipe to rupture, guaranteed the stability of product from heat exchanger refrigerant inlet junction.
