Abstract
The utility model discloses a low-noise energy-saving type direct current fan coil unit, which comprises a return air box and a unit shell. A forward multi-blade fan is arranged in the return air box, the forward multi-blade fan is connected with a direct current brushless motor, an air outlet of the forward multi-blade fan is provided with a flow equalizing flared opening, a heat exchange coil is arranged in the unit shell, the unit shell is provided with an air supply flange, and an air return flange is arranged on the return air box. The low-noise energy-saving type direct current fan coil unit is reasonable in structure, replaces an alternating current single-phase asynchronous motor by the direct current brushless motor, and reduces the energy consumption and the noise of the unit. Simultaneously, a flow equalizing silencer is added between the fan and the coil to further reduce the noise of the unit, thereby realizing a quiet and low-carbon air conditioning environment.
Description
Technical field:
The utility model relates to a kind of fan coil units.
Background technology:
National conditions along with expanding economy and China.Energy-conservation has been a fundamental state policy of China, and it must permeate, be dissolved into each production field.It is basis of China's sustained economic development, also is the basis of constructing economical society.Fan coil units is one of main end of central air-conditioning system, use wide, amount is big.Over year, the use of fan coil is all progressively increasing surplus in the of nearly ten, and the sales volume of 06 year fan coil has reached more than 2,000,000.Life-span as fan coil calculated with 10 years, and the coil pipe quantity of whole nation use at present is more than 1,000 ten thousand.But on technical performance, fan coil improves not quite for a long time.Unit and system energy consumption mainly contain several problems at present: 1. the pattern of thermofin and performance difficulty have breakthrough; 2. pay little attention to for relevant with water system big temperature difference unit production firm.Although require unit that the temperature difference of 6～7 ℃ even 8 ℃ is arranged from the energy-conservation angle of water system, but rare so far producer carries out comprehensive study, exploitation, test from aspects such as water passage, fin performance, noise, wind and water collateral resistances, provides product complete in specifications, function admirable to the client; 3. single phase ac asynchronous machine (then claim " AC motor ") is continuous with the cry that brshless DC motor (back claims " DC motor ") substitutes, but really implement to product and the stride of introducing to the market still very slow.
In addition, people are more and more higher to the requirement of quality of the life, working environment, and user's the noise to air-conditioning system is more and more paid attention to, but seldom have producer that the noise of fan coil is carried out specially treated, and the fan coil noise is all on same level.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the low-noise energy-saving type dc fan coil pipe unit that energy consumption is little, noise is low.
Technical solution of the present utility model is:
A kind of low-noise energy-saving type dc fan coil pipe unit, comprise air-intaking box, machine unit shell, it is characterized in that: the forward multiple wing blower fan is set in the air-intaking box, the forward multiple wing blower fan is connected with dc brushless motor, the forward multiple wing fan outlet is provided with the current-sharing horn mouth, heat exchange coil is set in the machine unit shell, the air-supply flange is set on the machine unit shell, the return air flange is set on the air-intaking box.
Current-sharing horn mouth wall adopts low frequency noise reduction cotton.
The utility model is rational in infrastructure, adopts dc brushless motor to replace single cross stream phase asynchronous machine, reduces unit energy consumption and noise.Simultaneously between blower fan and coil pipe, set up the current-sharing silencing means and further reduce the unit noise, realize the air conditioner surroundings of quiet, low charcoal.Unit adopts dc brushless motor to replace the single phase ac asynchronous motor, and unit is energy-conservation obviously, and overall energy consumption descends more than 50%; But suitability is strong, and motor can provide some kinds of different maximum speeds on request, and a motor can mate with the fan coil of plurality of specifications; Fan outlet is set up silencing apparatus, and the unit noise is low; Motor can adopt voltage, electric current, safeguard measure such as overheated, unit reliability height; DC electrical fault rate is low, easy to maintenance.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the configuration diagram of an embodiment of the utility model.
Fig. 2 is that Fig. 1 is a vertical view.
The specific embodiment:
A kind of low-noise energy-saving type dc fan coil pipe unit, comprise air-intaking box 15, machine unit shell 5, forward multiple wing blower fan 13 is set in the air-intaking box, the forward multiple wing blower fan is connected with dc brushless motor 11 by power transmission shaft 12, the forward multiple wing fan outlet is provided with current-sharing horn mouth 9, heat exchange coil 1 is set in the machine unit shell, air-supply flange 4 is set on the machine unit shell, return air flange 14 is set on the air-intaking box.
Current-sharing horn mouth wall 10 adopts low frequency noise reduction cotton.Also have condensate water guide plate 2, spring hole for hoist 3, drip pipe 7, condensate drain pan 8 among the figure.
