Description
Technical field
The invention belongs to the apparatus of air conditioning, particularly to the indoor improved evaporation refrigeration air conditioner that new wind is provided.
Background technology
Existing Evaporative Cooling Air Conditioning technology is to utilize water evaporates to absorb heat to reduce wind pushing temperature, makes a kind of air conditioning mode of room cooling.Air contacts the equipment that carries out the caloic exchange with water have various ways, is mainly direct Evaporative Cooling Air Conditioning device and indirect evaporation cooling air conditioner, and the combination of two kinds of forms.The air-conditioner that utilizes indirect evaporation cooling air conditioner and direct Evaporative Cooling Air Conditioning device tandem compound to form, its appearance and size is big, and structure is not compact.The air-introduced machine that is provided with is wanted two at least, and the electric energy of consumption is many.The air of introducing when air-introduced machine is during by direct heat exchanger, and the shower water of direct heat exchanger top enters heat exchanger, and directly contact and carry out caloic and exchange with air-flow in the heat exchanger, makes the air realization humidifying cooling of introducing.But, when air-introduced machine flows through direct heat exchanger with a large amount of air with certain speed, the water that from top to bottom flows along the heat exchanger plate face is blown by flow air, current are departed from along the direction that air flows, appearing on the area of a part of plate face in the heat exchanger does not have moisture film, and heat exchanger evaporation endotherm area is reduced.In addition, because heat exchanger is made of corrugated plating, when water flows, can appear at the phenomenon that the raised or sunken position of corrugated plating does not have moisture film to cover on corrugated plating.Like this, the heat exchange area of heat exchanger is reduced, heat exchange efficiency is reduced.
Summary of the invention
The object of the present invention is to provide a kind of improved evaporation refrigeration air conditioner, can increase the heat exchange area of heat exchanger, make air water heat exchange full contact, improve evaporative cooling efficient, energy savings, compact conformation, noise is low.
The object of the present invention is achieved like this: a kind of improved evaporation refrigeration air conditioner, be included in heat exchanger is installed in the casing, the top that is positioned at heat exchanger is being provided with spray water system, the below that is positioned at heat exchanger is being provided with the cistern that water pump is housed, the structure of heat exchanger is uniform connection support column in the gap between the hydrophilic aluminium foil plate that uprightly is arranged in parallel, the dual-side in the gap between the hydrophilic aluminium foil plate is being provided with the sealing support bar, the strip that this top margin gap of sealing is installed in the next gap in a gap, interval respectively in the uniform gap of the hydrophilic aluminium foil plate top margin that uprightly is arranged in parallel is evenly equipped with the water distribution box of hole for water spraying, in gap with water distribution box sealing top margin, be provided with on the one side and exporting, making heat exchanger constitute the space is arranged in parallel, dry passage and wet channel with import and outlet, the uniform respectively metal truss that is being provided with in dry passage and wet channel, the indoor metallic mesh group that is installed with of the direct evaporative cooling that below heat exchanger, is provided with, directly the closing in of evaporative cooling chamber lower tilt wall constitutes discharge outlet, discharge outlet is communicated with cistern, discharge outlet is deep into below the cistern waterline, and the opening part in direct evaporative cooling chamber bottom is being provided with the blower fan air outlet.
The present invention adopts bottom air-supply, ozone is sent into that the direct evaporative cooling of bottom of heat exchanger is indoor to enter heat exchange with the metallic mesh group by blower fan.Because the cooling water of heat exchanger wet channel falls through the metallic mesh group, be subjected to the metallic mesh group to stop collision, make repeatedly refinement of water droplet, fully contact with the new wind that rises, increase the evaporative cooling area.The cooling water and the last sector-style that fall form reverse convection current, tiny water droplet is attracted on the multiple layer metal net grid surface, when wind passes through, the heat of metallic mesh frame surface water is taken away in evaporation, the metallic mesh temperature is reduced, at this moment metallic mesh passes to cold sector-style again and falls into water down as the media of keeping cold here.So constantly move in circles, last sector-style is by cooling with whereabouts evaporation of water heat exchange.Be adsorbed on the cooling water that major part is not evaporated on the metallic mesh, assemble the back along being recycled in the inflow rose pond, inclined plane.Continue to rise through cooled new wind, enter in the heat exchanger.Because the dry passage of heat exchanger and the support column in the wet channel are staggered in order between the aluminium foil plate, constitute uniform optimal evaporation heat exchange gap between the aluminium foil plate.Respectively uniform metal truss in dry passage and wet channel has increased the heat exchange area of heat exchanger, makes air water heat exchange full contact, has improved the evaporative cooling effect.After the last sector-style of wet channel was finished the evaporative cooling task, outdoor by the outlet discharge, the last sector-style in the dry passage was sent into indoor after the heat exchange cooling.The metallic mesh group of the indoor installation of the direct evaporative cooling of the present invention has the effect that absorption reduces noise.The improved evaporation refrigeration air conditioner of the present invention has increased the heat exchange area of heat exchanger, makes air water heat exchange full contact, has improved evaporative cooling efficient, has reduced noise, energy savings, and compact conformation, cost is low, and operating cost is low.
