Abstract
The utility model discloses a fan coil capable of providing fresh air. The fan coil is characterized by comprising a casing, a cold/hot water coil pipe, an air feeding fan, an air discharging fan and a heat exchanger. A return air inlet, an air feeding port, a fresh air inlet and an air discharging port are arranged on the casing. The fresh air inlet is communicated with an inlet pipe opening of a first medium flow channel of the heat exchanger, the air feeding fan is arranged on a communicated air channel between a discharging pipe opening of the first medium flow channel and the air feeding port. The return air inlet is communicated with an inlet pipe port of a second medium flow channel of the heat exchanger, and the air discharging fan is arranged on a communicated air channel between a discharging pipe opening of the second medium flow channel of the heat exchanger and the air discharging port. The fan coil enables indoor air to be pure and cool and rich in oxygen. Simultaneously, the fan coil recovers cold air and heat in discharged air and achieves a purpose of saving energy and reducing consumption.
Description
Technical field
The utility model relates to a kind of end equipment of central air-conditioning, i.e. fan coil; Especially relate to a kind of can inletting fresh air, and have the fan coil of energy-saving effect.
Background technology
Along with development and the growth in the living standard of science and technology, the central air-conditioning large tracts of land is used in the places such as hotel, market, office building, residential area, and fan coil has obtained more general application as the end equipment of central air-conditioning.But the birth defects of air-conditioner self are also perplexing the user always, and the room air pollution under the air conditioner surroundings is serious, are the seeds of trouble that causes air conditioner disease, breathing problem, SARS virus, legionaires' disease outburst and propagate.Experimental results show that: in the rear room air of turning on the aircondition bacterial content be do not turn on the aircondition in the room 3-4 doubly, room air pollution has become the environmental factor of human health maximum.Under the air conditioner surroundings in the air oxygen content low, the resh air requirement problem can not get thorough solution always; Cold and hot amount can not get effective recovery always in the air conditioning air exhaust, and energy waste is startling.
This shows, be necessary the fan coil of central air-conditioning is improved.
The utility model content
Task of the present utility model is to solve the technological deficiency that central air conditioning fan coil unit of the prior art exists, and a kind of fan coil that can inletting fresh air is provided.
Its technical solution is:
A kind of fan coil that can inletting fresh air comprises casing, cold water/hot-water coil pipe, breeze fan, exhaust fan and heat exchanger; Be provided with return air entrance, air outlet, new wind entrance and exhaust outlet at casing; New wind entrance be communicated with heat exchanger the first medium runner enter the mouth of pipe, breeze fan is arranged on being communicated with on the air channel between the discharge mouth of pipe and the air outlet of first medium runner of heat exchanger; The return air entrance be communicated with heat exchanger the second medium runner enter the mouth of pipe, exhaust fan is arranged on being communicated with on the air channel between the discharge mouth of pipe and the exhaust outlet of second medium runner of heat exchanger.
Above-mentioned heat exchanger is plate type heat exchanger.
Above-mentioned air outlet is positioned at the end that casing arranges cold water/hot-water coil pipe, and exhaust outlet is positioned at the other end of casing.
Above-mentioned new wind entrance and return air entrance are arranged side by side.
The utlity model has following useful technique effect:
The utility model is when introducing outdoor new wind, energy in the indoor return air is exchanged by a heat exchanger, take to indoor by new wind, thereby make indoor various pollutants, such as smoke, floating dust, foul smell and other peculiar smell, all driven away with indoor planned air draft, make room air pure, pleasant, enough oxygen content; Simultaneously, also the cold and hot amount in the air draft is reclaimed, reach energy-saving and cost-reducing purpose.
Description of drawings
Below in conjunction with accompanying drawing and the specific embodiment the utility model is illustrated further:
Figure is the structural principle schematic diagram of a kind of embodiment of the utility model.
The specific embodiment
By reference to the accompanying drawings, a kind of fan coil that can inletting fresh air comprises casing, chilled water coil or hot-water coil pipe 8, breeze fan 1, exhaust fan 2 and heat exchanger 3.Be provided with return air entrance 4, air outlet 5, new wind entrance 6 and exhaust outlet 7 at casing.The preferred plate type heat exchanger of above-mentioned heat exchanger, new wind entrance be communicated with plate type heat exchanger the first medium runner enter the mouth of pipe, breeze fan is arranged on being communicated with on the air channel between the discharge mouth of pipe and the air outlet of first medium runner of plate type heat exchanger; The return air entrance be communicated with plate type heat exchanger the second medium runner enter the mouth of pipe, exhaust fan is arranged on being communicated with on the air channel between the discharge mouth of pipe and the exhaust outlet of second medium runner of plate type heat exchanger.
Preferably, above-mentioned air outlet is positioned at the end that casing arranges chilled water coil or hot-water coil pipe, and exhaust outlet is positioned at the other end of casing.Above-mentioned new wind entrance and return air entrance can be arranged side by side.
Operation principle of the present utility model roughly is:
The air of indoor dirt enters plate type heat exchanger through the return air entrance, then is discharged to outdoor, outdoor new wind by exhaust fan and enters plate type heat exchanger by new wind entrance and deliver to new wind indoor by breeze fan.Cold and hot exchange occurs in new wind and return air in plate type heat exchanger, new wind is taken back the cold and hot amount in the air draft indoor, has reduced indoor cooling and heating load, in order to reach healthy, energy-conservation purpose.
The technology contents of not addressing in the aforesaid way is taked or is used for reference prior art and can realize.
Need to prove that those skilled in the art can also make such or such easy variation pattern under the instruction of this specification, such as equivalent way or obvious mode of texturing.Above-mentioned variation pattern all should be within protection domain of the present utility model.
