Abstract
The invention relates to a low-noise screw rod type refrigerating machine unit for a ship. The low-noise screw rod type refrigerating machine unit comprises a base, an evaporator, a condenser and a compressor, wherein an evaporator support frame and a condenser support frame which have the same height are respectively surrounded and connected with the outer side of the evaporator and the condenser, the evaporator and the condenser are respectively and parallelly arranged on the base through the evaporator support frame and the condenser support frame, a compressor support frame is arranged at the bottom of the compressor, and is supported on the upper surfaces of the evaporator support frame and the condenser support frame, the evaporator, the condenser and the compressor are connected through hoses, the compressor support frame is parallelly supported in the center positions of the upper surfaces of the evaporator support frame and the condenser support frame through a plurality of shock absorbers, the axial lines of the compressor, the condenser and the evaporator are parallel, and the outer side of the compressor is provided with a sound isolation cover. The low-noise screw rod type refrigerating machine unit has the advantages that the structure is simple, the design is reasonable, the use noise is low, the vibration is small, the service life is long, and the shielding performance is high.
Description
Technical field
The present invention relates to naval vessel refrigeration unit, relate to specifically a kind of naval vessel low noise screw type cold unit.
Background technology
On naval vessel, the normal naval vessel being equipped with easily produces noise and vibration by refrigeration unit at present, its source mainly comes from compressor, there is no effective inhibition means for noise and vibration, the noise and vibration that refrigeration unit produces in operation had not only affected crewman's rest but also had affected the entirety disguise on naval vessel.
Summary of the invention
For solving the larger problem of the naval vessel conventional naval vessel being equipped with refrigeration unit noise and vibration, the invention provides a kind of simple in structure, reasonable in design, use noise low, shake little, the life-span long, disguised high naval vessel low noise screw type cold unit.
The technical scheme that the present invention takes is:
Low noise screw type cold unit for a kind of naval vessel, comprise base, evaporimeter, condenser and compressor, the outside of described evaporimeter and condenser is enclosed respectively and is connected to contour evaporator support and condenser brackets, evaporimeter and condenser are set up in parallel on base through evaporator support and condenser brackets respectively, it is characterized in that described compressor bottom is provided with compressor bracket, compressor bracket through multiple shock absorber parallel supports in the center of evaporator support and condenser brackets upper surface, compressor, the axis of condenser and evaporimeter is parallel, compressor outside is provided with blimp, evaporimeter, condenser is connected through flexible pipe with compressor chamber.
Further, described blimp comprises framework and polylith panel, and panel and framework enclose and connect as closed cavity.
Further, described panel comprises double-layer plate and sound absorption cotton, and described sound absorption cotton is arranged between double face slab.
Again further, described compressor is semi-closed screw type compressor.
The present invention takes the beneficial effect of above technical scheme to be:
(1) compressor adopts semi-closed screw type compressor, traditional piston compressor that compares, and screw compressor has the raising of the less and Energy Efficiency Ratio of identical refrigerating capacity lower volume; Because screw compressor is the pulse exhaust mode of continuous exhaust pneumatic wallop instead of piston compressor in the running, the generation of noise and vibration while having reduced greatly unit operation; Screw compressor moving component is few, and the probability that breaks down is little, is convenient to unit maintenance, the security that has improved unit.
(2) adopt acoustic hood by isolated to the helical-lobe compressor of refrigeration unit and extraneous air, acoustic hood adopts frame structure of aluminum alloy, panel adopts fills the cotton compacting of sound absorption in the middle of double-layer plate and forms, have intensity high, lightweight, can effectively cut off the noise of compressor to outside transfer of air.
(3) compressor and acoustic hood have special base, between base and evaporimeter, condenser brackets, use rubber absorbers to be connected, and compressor suction and discharge interface is connected with exterior line by metal hose, by above measure, weaken the vibration of unit and the transmission of noise, the disguise on naval vessel is improved.

Fig. 1 is front view of the present invention;
Fig. 2 is left view of the present invention.
In figure: base 1, condenser brackets 2, evaporator support 3, condenser 4, evaporimeter 5, compressor bracket 6, compressor 7, shock absorber 8, blimp 9.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described:
As shown in the figure, a kind of naval vessel comprises base 1 with low noise screw type cold unit, condenser brackets 2, evaporator support 3, condenser 4, evaporimeter 5, compressor bracket 6, compressor 7, shock absorber 8, blimp 9.Described compressor bracket 6 is semi-closed screw type compressor, evaporimeter 5, between condenser 4 and compressor 7, be connected through flexible pipe, evaporimeter 5 encloses respectively and is connected to contour evaporator support 3 and condenser brackets 2 with 4 outsides of condenser, evaporimeter 5 and condenser 4 are set up in parallel on base 1 through evaporator support 3 and condenser brackets 2 respectively, described compressor 7 bottoms are provided with compressor bracket 6, compressor bracket 6 through multiple shock absorber 8 parallel supports in the center of evaporator support 3 and condenser brackets 2 upper surfaces, compressor 7, condenser 4 is parallel with the axis of evaporimeter 5, compressor 7 outsides are provided with box blimp 9.Blimp 9 comprises framework and 5 panels, and panel and framework enclose the cavity and the compressor bracket 6 that connect and form confined space.
