Abstract
The utility model discloses a standard refluxing dry type fan-coil unit which can be completely discharged which mainly consists of a blower and a fan-coil type heat exchanger; a ventilating surface of the fan-coil type heat exchanger is in a level state or in an incline state less than 10 degrees than the level plane. An air flow vertically passes through the pan-coil type heat exchanger; the cold medium or the hot medium of a pipe coil of the pan-coil type heat exchanger flows to the windward side from the leeside. The fan-coil unit can lead the pipe coil to be completely exhausted and discharged under the premise of standard refluxing heat exchange between air and the cold medium or the hot medium, thus greatly improving the heat exchange efficiency of the heat exchanger.
Description
Technical field
The utility model relates to the apparatus of air conditioning, exactly is the dry-type fan coil unit that is used for cooling off or adding hot-air in the humiture independent regulation air-conditioning system.
Background technology
Dry-type fan coil unit in the existing air-conditioning system mainly is made up of blower fan (containing drive motors) and coil exchanger, blower fan is responsible for providing air circulation power, cold (heat) the matchmaker coil exchanger of flowing through, carry out exchange heat with air, air be cooled (heating), relative current between the heat exchange effect of coil exchanger and air and cold (heat) matchmaker is to relevant, and cold (heat) matchmaker is to improve the effective measures of coil pipe heat exchange efficiency from the accurate adverse current form that coil pipe lee face one side flows to windward side one side successively.
As shown in Figure 1 and Figure 2, this dry-type fan coil unit mainly is made up of blower fan 2 and coil exchanger 1, adopt coil pipe to cross the arrangement of wind face or wide-angle tilt vertical with horizontal plane, if cold (heat) matchmaker's flow arrangement adopts accurate reflux type, then be difficult to realize the venting and the emptying of tube side, easily because of height point gas collection causes tube side gas stifled, or because of being emptied completely freezing coil pipe (when cold district uses).
The utility model content
At the deficiency that above-mentioned existing dry-type fan coil unit exists, the purpose of this utility model is to provide a kind of fan coil units that can realize convenient again venting of accurate adverse current and emptying, to reach the purpose that improves heat exchanger heat exchange effect.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of accurate reverse flow dry fan coil units that can be emptied completely, comprise blower fan and coil exchanger, the wind face of crossing of described coil exchanger is level or horizontal by the heeling condition less than 10 °, air-flow is vertically by coil exchanger, and refrigerant or heating agent in its coil pipe flow to windward side one side successively from lee face one side.
Described airflow direction is arranged from top to bottom.
Described airflow direction is arranged from bottom to top.
The refrigerant of described coil exchanger or heating agent are kept supplying back formula or are upward supplied formula method of supplying next time under being.
Described coil exchanger is provided with deflating valve at the peak of its coil pipe, and minimum point is provided with the sluicing mouth.
Described fan coil units is horizontal, vertical or card top formula structure.
The utility model can make the coil pipe of dry-type fan coil unit exit fully and emptying under the prerequisite that realizes accurate countercurrent flow between air and cold (heat) matchmaker, has improved the heat exchange efficiency of heat exchanger greatly.

As shown in Figure 3, this horizontal fan coil units mainly is made up of blower fan 2 and coil exchanger 1, coil exchanger 1 is located at the unit inlet side, it crosses that wind face (referring to the plane parallel with the coil pipe windward side) is level or horizontal by the heeling condition less than 10 °, air-flow vertically passes through coil exchanger from bottom to top, in air side, processed air flows through coil pipe under centrifugal blower drives, air is cooled or heats, cold (heat) matchmaker in the coil pipe flows to windward side one side successively from lee face one side, see along airflow direction, blower fan 2 places the back of coil exchanger, cold (heat) matchmaker can be water or other liquid refrigerant, supply formula method of supplying next time in the employing, enter from the water inlet of coil pipe lee face one side, first row's arm of starting at, flow through one or more flow processs earlier from lee face, enter second row's arm again and flow through one or more flow processs, enter the 3rd row's branch road then, the rest may be inferred, the row's arm that flows through at last near the windward side arrives delivery port, the accurate countercurrent flow of realizing ideal, and the coil exchanger water inlet is provided with deflating valve, the delivery port place is provided with the sluicing mouth, can realize coil pipe venting and cold (heat) matchmaker emptying easily.
As shown in Figure 4, this vertical fan coil units mainly is made up of blower fan 2 and coil exchanger 1, and coil exchanger 1 is located at air side, unit bottom, in air side, blower fan 2 drives processed air and flows through coil pipe from top to bottom, air is cooled or heats, and in the tube side side, cold (heat) matchmaker enters from the water inlet that is positioned at the coil pipe bottom, flow out from the top delivery port, realize accurate countercurrent flow with air, coil exchanger delivery port place is provided with deflating valve, and the water inlet is provided with the sluicing mouth.
As shown in Figure 5, this vertical fan coil units mainly is made up of blower fan 2 and coil exchanger 1, adopt the version that goes out on advancing down, coil exchanger 1 is located at air side, unit top, the oblique layout of air outlet, all the other structures and above-mentioned vertical fan coil units are basic identical, just repeat no more here.
The utility model is not limited to above-mentioned preferred forms, and anyone can draw other various forms of products under enlightenment of the present invention.For example fan coil units is horizontal, vertical or blocks top formula structure or the like.Though but on its shape or structure, do any variation, every identical with the utility model or akin technical scheme is all within its protection domain.
