Description
Technical field
The present invention relates to the air-conditioning technique field, is a kind of B grade supporting fixed device of compressor that reduces vibrating noise specifically.
Background technology
With the air regulator is the example explanation: for comfortable temperature environment is provided to the user, air regulator utilizes the compressor of A with the refrigerant boil down to HTHP gaseous coolant of low-temp low-pressure gaseous state as shown in Figure 6; The condenser that warm high-pressure liquid refrigerant discharged internal heat simultaneously during B changed the HTHP gaseous coolant into; C changes the middle temperature high-pressure liquid refrigerant in the condenser into the expansion valve of low-temp low-pressure liquid refrigerants; D change the low-temp low-pressure liquid refrigerants gaseous coolant of low-temp low-pressure into and absorb refrigerant circulating pipeline structure capable that the parts such as evaporimeter of surrounding environment heat constitute to indoor refrigeration, heat or purify air.
In addition, air regulator still divides to be arranged in one according to cooling/heat release function setting again and is divided into one-piece type and separation type.Integral air conditioner is cooling (refrigeration)/heat release (heating) function integration, burrows on the wall in house or installs on window, and Saperated air conditioner is divided into indoor set and off-premises station.It is cabinet type, wall-hanging, embedded etc. that Saperated air conditioner is divided into again.
Be illustrated in figure 7 as the single cold window air conditioner of existing integral type, it is by the cabinet that forms appearance; The chassis of parts is installed; Be arranged at the indoor panel of indoor, chassis part, indoor panel central authorities are formed with air inlet, and the upper and lower left and right side of panel has exhaust outlet; The indoor panel inboard is disposed with evaporimeter 7; It divides into drip tray; Indoor centrifugal fan 5; The air guiding; The dividing plate 6 of indoor and outdoor part; Outdoor section has the fan electromotor 4 of dividing plate arranged outside in frame; Be fixed in the compressor 1 of chassis outdoor section by the vibration damping rubber cushion; Expansion valve 9; Be installed on the outdoor aerofoil fan 3 of fan electromotor outer shaft; Be arranged at the condenser 2 in the aerofoil fan outside on the chassis.
Its running process of refrigerastion is: compressor and fan motor runs when inserting power supply, refrigerant in its medium circulation pipeline by compressor compresses after by outdoor condenser heat release, be back to gas-liquid separator for compressor again after absorbing heat through the evaporimeter of expansion valve, indoor section again and carry out reciprocation cycle; And along with the running of fan electromotor, the indoor and outdoor fan begins to rotate, room air enters air-conditioner by indoor panel central air induction mouth, passing evaporimeter carries out the upper and lower left and right exhaust outlet that heat exchange becomes behind the cold air by indoor panel and flows back to indoor again, outdoor air enters air-conditioner by the side air inlet, and carrying out heat exchange through outdoor fan, condenser is that heating installation is discharged outdoor by central exhaust outlet.
And for example split type single-cooling air-conditioner, its indoor set are formed the indoor cabinet of appearance by the carrying parts; The casing front has enters hot-air and cold air is discharged the indoor unit panel of grid; Filter; Box house is equipped with evaporimeter on the chassis; Air guide; Formations such as following installation room internal fan.Off-premises station is by the compressor of installing by the vibration damping rubber cushion on the chassis in the outdoor cabinet; Condenser is arranged in addition; Outdoor fan; The air guiding; Air-inlet grille; The grid of giving vent to anger; Formations such as filter, HTHP gaseous coolant warm high-pressure liquid refrigerant in the condenser heat release is condensed into of compressor compresses output during the energising running, by changing the low-temp low-pressure liquid refrigerants behind the expansion valve again into, enter indoor evaporator by the tube connector between indoor unit and outdoor unit again and be vaporizated into the low-temp low-pressure gaseous coolant, and absorption surrounding environment heat reaches the purpose of refrigeration, airborne moisture content aggegation is on the fin of evaporimeter in the process of refrigerastion, later repetitive cycling said process.
But as mentioned above, there are the following problems to be installed on the compressor on chassis by the vibration damping rubber cushion in various air-conditioner: compressor adopts bolt to belong to the one-level supporting system by the rubber damping elastic mounting on the chassis of air-conditioner as shown in Figure 1, the low frequency noise that this kind supporting fixedly makes complete machine produce is still very big, experiment is found, when the noise of compressor own is also little, the buzz that air conditioner casing and compressor resonance produce just has the 20-30 decibel, for the one-level supporting system as shown in Figure 2 its vibration mechanics equation be: MX "+C (X '-U ')+K (X-U)=Fsin (ω t); in the formula: the quality of M-compressor, the vibration displacement of X-compressor; The damped coefficient of C-vibration damping rubber cushion; The coefficient of elasticity of K-vibration damping rubber cushion; The vibration displacement on U-chassis; The vibration frequency of ω-compressor.The object function of finding the solution is: U/X (ω/ω n), this low-frequency vibration long term be in people, and disease such as cause neurasthenia, insomnia easily, have a headache, be losing one's memory propagates into air-conditioning duct and can make that the pipeline stress is tired breaks or disconnect.The vibration that causes according to the compressor direction of rotation is proportional to the capacity of compressor, be inversely proportional to the inertia of compressor and the quadratic relationship of rotary speed, the way of traditional reduction vibration of compressor noise is that the degree of balance that increases its inner rotating part, the weight that increases compressor are coherence, pipeline adopts vibration-proof material and vibration protection, but these all can increase the cost of product undoubtedly simultaneously.
Summary of the invention
The present invention provides a kind of B grade supporting fixed device of compressor that reduces vibrating noise for the problem that solves above-mentioned prior art and exist, and its technical scheme of dealing with problems includes: the compressor that is bolted in air-conditioner with three pin sheets with through hole of being separated by 120 °; Compressor is bolted in the bolt of air-conditioner; Being connected to the rubber damping rubber cushion that bolt, pad be connected to below the compression under-chassis sheet constitutes, it is characterized in that: its three the pin sheets with through hole are welded in the middle and lower part of compressor housing, three pin sheets with through hole are bolted in three pin sheets that a upper and lower side all is welded with three the pin sheets identical with it and can holds the ware shape fixed support upper end of its underpart compressor housing below by the vibration damping rubber cushion, and three pin sheets of said fixing support lower end pass with bolt again and are bolted on the chassis of air-conditioner by the rubber damping rubber cushion between pin sheet and chassis.
The above-mentioned support bracket fastened internal diameter of ware shape that can hold the bottom compressor housing, the degree of depth be greater than its compressor lower case of holding, and do not contact when the system vibration with the two and be advisable.
The pin sheet that above-mentioned three of the support bracket fastened upper and lower sides of ware shape that can hold the bottom compressor housing have through hole can misplace an angle as 60 ° so that install.
Above-mentioned ware shape fixed support has the U-shaped opening in the design of the edge at gas-liquid separator for compressor air inlet place.
Advantage and good effect: being shown in the compressor quality as Fig. 3,4,5 is that M and chassis quality are that quality of socket is M in the fixed system of m
