Abstract
The utility model relates to an indirect evaporative refrigeration fresh air unit, which solves the problems that: fresh air load takes up a quite large ratio in the air-conditioning system, and becomes the main load; when a more complex equipment is adopted, the problems of energy waste, higher equipment investment and running cost occur. The utility model comprises a casing of the primary inlet and outlet, a casing of the secondary inlet and outlet, a heat exchanger, and other members, which is characterized in that: a water tank connected with a water distributor through a water pump and a flow pipe is arranged in the casing; the heat exchanger is arranged at the lower part of the water distributor, and an alternate primary passage in horizontal direction and a secondary passage in vertical direction are arranged in the heat exchanger. The utility model has the advantages of exhaustion cooling capacity recovery in the air-conditioning room with high efficiency in summer (heat recovery without water spraying in winter), capability for refrigeration with high efficiency in summer, large fresh air energy consumption saving, and low investment and running cost.
Description
Technical field
The utility model belongs to a kind of refrigeration plant, the new blower fan group of particularly a kind of indirect evaporation refrigerating formula.
Background technology
In air-conditioning system, new wind load usually occupies sizable ratio, and especially in not allowing the single flow air-conditioning system of return air (as SPF level animal used as test Clean room), new wind load becomes main load.When the equipment that adopts more complicated (as using handpiece Water Chilling Units summer, water systems such as cooling tower, winter is with boiler water system etc.), paying sizable energy consumption is cost (electric energy, heat energy etc.) parameters needed is arrived in air-treatment, after the interior hot humidity load of absorption chamber, some air (single flow is whole) will be discharged to outdoor, this has not only wasted the energy, increased operating cost, and investment of equipment is also than higher, especially the single flow air-conditioning system, adopt the brand-new wind can not return air (as SPF level animal used as test Clean room), its building cost operating cost is quite high, so that construction unit is difficult to bear, influences its construction.
The utility model content
The purpose of this utility model provides the new blower fan group of a kind of indirect evaporation refrigerating formula, not only can high efficiency reclaim the cold (do not spray water winter and reclaim heat) of air-conditioned room air draft summer, can also freeze with the high energy efficiency ratio, save the novel wind energy consumption in a large number in summer, reduce investment, operating cost is low.
The purpose of this utility model is achieved by the following technical solution: it comprises housing with wind inlet and outlet, secondary wind inlet and outlet and heat exchanger etc., it is characterized in that: in housing, be provided with water tank, water tank is connected water-locator by water pump with feed pipe, heat exchanger is set below water-locator, once distinguished and admirable road of staggered horizontal direction and the distinguished and admirable road of vertical direction secondary are set in the heat exchanger.
Operation principle: the water in water tank is through water pump, feed pipe, by water-locator spray the distinguished and admirable road of secondary of heat exchanger internal face (also being once the outside wall surface in distinguished and admirable road) and to dirty, on heat-transfer surface, form water membrane, secondary wind blows from bottom to top, a wind is by adjacent once distinguished and admirable road, and both produce heat exchange.Promptly blow over when having water membrane surperficial from the secondary wind (unsaturated humid air) of indoor discharge, moisture content is evaporated from the heat-transfer surface top layer, absorbed the heat of wind of heat-transfer surface and adjacent channels (the new wind of air), a wind (the new wind of air) cools waiting under the wet condition, and this process is called the indirect evaporation cooling.If directly spray undersaturated humid air with recirculated water, formed is the humidifying cooling constant-enthalpy process.When both heat exchange efficiencies were identical, indirect evaporation can obtain lower dry-bulb temperature under the situation that does not increase water capacity.
The utility model has the advantages that: can not only high efficiency reclaim the cold (do not spray water winter and reclaim heat) of air-conditioned room air draft, can also freeze with the high energy efficiency ratio, save the novel wind energy consumption in a large number in summer.The one, reduced air conditioner load, dwindled the specification of cooling and heating machine.Because new wind (wind) is after the new blower fan group of indirect evaporation refrigerating formula, air near or meet the requirements of air parameter, the air-conditioning unit is handled a little or is not dealt with this part air and gets final product, in the direct current air cleaning and conditioning system that has, since it is not really high to the requirement of summer air-conditioning humiture, so that can be without handpiece Water Chilling Units, cooling tower and water system thereof, thus investment and operating cost reduced.The 2nd, the new blower fan group of indirect evaporation refrigerating formula is that cost reaches the cooling refrigeration with the low energy consumption.Because new wind during by the new blower fan group of indirect evaporation refrigerating formula, carries out the exchange of sensible heat and latent heat with air draft (secondary wind), therefore can produce subzero temperature difference effect, promptly new wind outlet dry-bulb temperature is lower than air draft inlet dry-bulb temperature.And the energy that consumes is the energy that water circulating pump and exhaust blower consume.Energy Efficiency Ratio can reach 13, compares with other refrigeration plants to have remarkable advantages, and power consumption and operating cost are very low.The 3rd, the new blower fan group of indirect evaporation refrigerating formula does not need the outside that cold (heat) source is provided, and relatively simple for structure, cost is low.
