Abstract

The utility model relates to a novel air conditioning fan which is characterized in that a row of flat pipes (17) are fixedly arranged in equal height and equal distance between a front pipe plate and a back pipe plate (16) of a rectangular heat exchanger (9) in a cabinet type machine body (2), and the flat pipes (17) are generally and fully covered with water-absorbing gauze (18) and droop to the plate surface of a bottom plate (20). After water is injected on the bottom plate (20), blower fans (14), (15) are started to make air flow occur respectively in the inner pipe pass and the shell pass of the heat exchanger (9), and air currents with large humidity of the shell pass are led outdoors. Because of the action of the continuous phase change heat absorption of water molecules on the water-absorbing gauze (18), the flat pipes (17) are kept at the wet bulb temperature. Thus, indoor hot air continuously flows across the inner cold wall of the flat pipes (17), and heat is lost for refrigeration to achieve the air conditioning effect that the room temperature is lowered by 2 to 6 DEG C.

Description

The air-conditioning fan

The utility model relates to air-conditioning technique, specifically is a kind of air-conditioning fan.

At present, its performance indications of the air cooler on the market are: back on the rocks leaving air temp is lower than room temperature 2-6 ℃; Not on the rocks, do not have the cold wind effect through using proof.Yet the cold wind index is the critical index of this product, and other conformability index such as electronic control technology are very strong even this index is very weak, and eventually because of not satisfying the needs of consumer to cold wind, what only can suffer consumer's mercilessness negates.In addition, this product is when the refrigeration air-supply, the vaporize water of decalescence is arranged in indoor in company with " cold wind ", increase a humidity for indoor air, according to correlation theory and experience, the room air water capacity is originally higher should the situation of dehumidification under, especially in the Yangtze river basin and the areas to the south, the result of humidification only can increase feeling of oppression and heat.But the humidification of this product is interdependence with sending cool breeze, wants to cancel humidification, equals to have cancelled this product itself.Obviously, this product is because of existing major defect, so need be sought technical support on refrigeration mechanism, in the hope of the correct road that effects a permanent cure on the refrigeration mechanism.

The purpose of this utility model provides a kind ofly without compressor and fluorine, does not also need by ice cube to show the cold wind effect, but rely on structural doing in the proper way, promptly obtain reliable and stable cold wind effect, and can arrange the phase transformation vaporize water in the open air, thereby can be used for the air-conditioning fan of enclosed cooling.

The purpose of this utility model is achieved in that makes flat tube with the pipe of shell-and-tube heat exchanger, the flat tube wall completely wraps the gauze that one deck corrosion resistant is fungi-proofing and water absorption rate is high outward, this gauze hangs down to the base plate face, the flat horizontal surface of flat tube is parallel and vertical with the board plane of front and back two tube sheets with the baseplane with two metopes about the rectangle outer cover of heat exchanger, equidistantly be provided with between the pipe, its the pipe end near but do not contact base plate, pipe leans and does not closely also contact cover plate, on the cover plate of pipe one end, a rectangle air inlet be arranged in parallel along the tube sheet limit, on the base plate of the pipe other end, be rectangular discharge pipe then corresponding to the parallel mouth of pipe of establishing in tube sheet limit, the upper orifice of this discharge pipe is fixed by design spilling water height apart from the base plate plane height, its lower nozzle is right after the corresponding air inlet desired height of the heat exchanger of its lower floor to be decided with insertion apart from the base plate plane height, and discharge pipe end opening size cooperates airtight requirement fixed with the air inlet size by male and female.Like this, on the base plate in the housing, inject water liquid, the outer gauze of pipe has been filled moisture content, start blower fan thereupon, make tube side and shell side air occur and flow, and make the air-out of shell side lead to the open air, the air intake and the air-out of tube side are indoors circulated, then on business know the wet and dry bulb temperature difference data, can obtain low cold wind, make the indoor stable comfortable air-conditioning effect that does not need additional conditions that reaches.

Below, be further described with accompanying drawing in conjunction with the embodiments:
