Description

A kind of ultra-silent energy-saving DC speed-changing indoor set

Technical field

The utility model relates to Central air-conditioning unit end-equipment, is specifically related to a kind of super quiet energy-conservation speed change indoor set.

Background technology

Fan coil mainly relies on the positive action of blower fan, air is heated by during surface cooler surface, thus enhances the heat convection between surface cooler and air, can the air of heat rooms rapidly.Fan coil is the end equipment of air-conditioning system, and its operation principle is the air in constantly recirculation room, place in unit, make air by with cold water (hot water) heat exchange of surface cooler Inner eycle after cooled (heating), to keep the constant of room temperature.

Fan coil (non-four sides air-out) main in the market has Horizontal type concealed, horizontal bright dress, ceiling embedded type three types fan coil, generally need when order collecting head mode (the right alive, the left side) is described, whether be with air-intaking box, then need as being with air-intaking box air return method (rear return air or lower return air) is described, air return method cannot be changed in erecting bed.

There is some deficiency following in the fan coil of main flow in the market:

1, air return method scene can not be changed, and when running into erecting bed and will changing design, then needs again to order fan coil;

2, part water pond exposes, the easy dust stratification of water pond or other impurity, easily blocking condensate water discharging mouth;

3, the condensation mouth of a river is again bottom fan coil, makes troubles to installation, as the drainpipe angle of inclination of installing not or water pipe distortion, then condensed water may be caused to pour in down a chimney return fan coil pipe; Meanwhile, discharge outlet is in the bottom of unit, and the condensed water in the eliminating water pond of safety, then the end of drainpipe needs more much lower than unit, so just reduces the usage space of user.

4, fan coil water pond in the market has two kinds, and one is the shaping rear welding discharge outlet of general steel plate or galvanized sheet, and surface is plastic-blasting again, and another kind is that stainless steel is shaping, welding discharge outlet; Bond during assembling one layer of heat preservation cotton outside water pond, and in use heat-preservation cotton is directly in atmosphere exposed, along with the lengthening of service time, heat-preservation cotton is aging, plastic-blasting can produce come off, welding position oxidation produce thereupon, thus impact use;

5, surface cooler is vertically installed, while meeting return air area and air quantity, make the Thickness Ratio of fan coil comparatively large (at present fan coil thickness be about 240-250mm) on the market, take the usage space of user, consider the gradient of condensate draining pipe, the usage space of user is less; If user needs ultra-thin fan coil, mode main be in the market unit length constant when, reduce the hole count of surface cooler and realize, the consequence done like this be just heat exchange amount wretched insufficiency, only have and meet by increasing unit quantity, the energy consumption of the user being increases.

6, metal spiral case, impeller are connected by securing member, and under the high-speed cruising, slight vibrations of motor, in use for some time, because of the vibrations friction between metalwork, noise can be increasing;

7, surface cooler fin is in for a long time and directly contacts with air, and the floating thing in air flows with along with air, adheres to surface cooler return side by return air inlet, is easy to blocking, reduces air-conditioning effect;

8, adopt common asynchronous moter, make the rotating speed reaching needs during unit starting immediately, have a strong impact on electrical machinery life, start the vibrations brought simultaneously and make unit easily produce noise, affect the experience of user;

9, according to some use habits, as when window is opened, continue to use fan coil units, result of use will be made very poor, cause energy waste.

Therefore, for the problems referred to above, the utility model proposes a kind of new technical scheme.
