The air handling unit is reasonable in structure, and can effectively utilize much coldness in low-temperature condensed water which is generated by the surface air cooler of an air conditioning unit.
Description
Technical field
The utility model relates to a kind of air-treatment unit.
Background technology
" public building energy design standard " (GB50189-2005) points out that in the annual energy consumption of public building, about 20%～30% is consumed in illumination, and 50%～60% is consumed in air conditioner refrigerating and heating system.So air conditioner load that should the zone is significantly increasing.On the other hand, because the development of this regional economy, people improve constantly the environmental requirement of living and handle official business, and cause also constantly increased the service time of air-conditioning.Use survey data to show according to 5 years in the past to this regional air-conditioning, and went down according to present trend development, and in coming 10 years, used the power plant that causes this zone must increase 3 Ge Zhou Ba scales just can tackle because air-conditioning increases.Simultaneously, China is energy resource consumption big country, and along with expanding economy, energy day is becoming tight.
" People's Republic of China's national economy and social development 11th Five-Year Plan outline " proposes, and will reduce about 20% in China's per Unit GDP Energy Consumption the five-year.Therefore, research and development are also promoted high-efficiency air-condition equipment, end-equipment, and the work that reduces the air-conditioning system consumption reduction is imperative.
In the all-air conditioning system, often need air conditioning area is replenished a certain amount of fresh air, satisfy indoor people to oxygen demand.And outdoor fresh air often temperature is higher, water capacity is large, can separate out a large amount of moisture after the cooling, and temperature lower (at 12 ~ 15 ℃).Take District of Shanghai as example, the Air-conditioner design operating mode in summer is that DB34 ℃, relative humidity 70%, absolute moisture content are 24.2g/kg.Suppose that wind pushing temperature is DB18 ℃, relative humidity 95% behind the surface cooler, can think that water capacity is 12.4g/kg.The absolute moisture content difference is at 11.8 g/kg, namely 10000m
3Can separate out the water at low temperature of about 142kg/h after the new wind of/h is cold through table.And we often directly discharged the water of this part in the design of air-treatment unit in the past, were not used.
Summary of the invention
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and can effectively utilize the new wind-breakage water precooled air of cold in a large amount of lower temperature condensed waters that air-conditioning unit surface cooler produces to process unit.
Technical solution of the present utility model is:
A kind of new wind-breakage water precooled air is processed unit, it is characterized in that: comprise shell, arrange upper and lower two-layer in the shell, the upper strata arranges air outlet, lower floor arranges fresh wind port, behind fresh wind port, set gradually roughing efficiency air filter, medium effeciency filter, heat exchanger is set behind medium effeciency filter, heat exchanger is provided with water inlet pipe and water outlet pipe, the heat exchanger bottom is provided with water-collecting tray, and the shell side of heat exchanger communicates with the water tank of heat exchanger upper end, and the water tank top arranges the surface cooler that is arranged in the upper strata, blower fan is set behind the surface cooler, is air outlet behind the blower fan.
Described roughing efficiency air filter is roughing-efficiency plate filter, and medium effeciency filter is the pocket type medium effeciency filter.
Water tank is provided with pressure switch, and described water-collecting tray is the hermetic type water-collecting tray, and the type water-collecting tray that gathers is provided with one-way pressure valve.
Be provided with inorganic bacteria-proof film at water tank inlet.
The utility model is rational in infrastructure, utilizes new blower fan group that the water at low temperature of separating out after the air cooling is carried out precooling to new wind, reclaims thermic load and reduces system energy consumption (10000m
3The recyclable thermic load 2.5Kw of new blower fan group of/h);
Below the folded formula structure of unit employing two sections, surface cooler the precool heat exchanger device is set, utilizes the deadweight of water as the power of water at low temperature, overcome the resistance of heat exchange coil; Hermetic type water-collecting tray of heat exchanger bottom design prevents air turnover condensed water side; The hermetic type water-collecting tray is joined one-way pressure valve, and after reaching certain hydraulic pressure in the coil pipe, pressure valve is opened and discharged, simultaneously also definitely heat exchange fully; Stainless steel condensation water tank of Surface cooling coil bottom band, condensation water tank is by the collecting water from runoff of pressure switch control condensation water tank and the plate side discharge of bottom compound heat-exchanger; Condensed water filter to adopt inorganic bacteria-proof film to filter, but purification and condensation water not only has bacteriostasis simultaneously, prevents secondary pollution; The upper and lower side of heat exchanger designs with water inlet pipe and water outlet pipe, and summer, can carry out heating function winter by water inlet pipe and water outlet pipe as the heat-exchangers of the plate type of condensed water; Unit adopts cold-prevention bridge shape steel construction, and chilled water parts, the condensed water parts that can effectively stop a plurality of low forms produce the cold bridge problem; Unit adopts folded formula structure, and connection and reasonable arrangement is compact, and floor space is few; Heat exchanger coils adopts the lower resistance design, and units consumption is low.
