The results showed that the bacteria are seriously overweight, about 25% pass rate of 58%; fungi seriously exceeded 29 percent pass rate was 45.83%. 20_8% of the building with central air conditioning is never on the pipe to clean up the research found that many buildings in the central air conditioning and ventilation system design is unreasonable, the air main channel mostly reserved for the manhole can not be piped dust collection and daily cleansing and disinfection. Leakage of ammonia from a cold store of a slaughter plant in Shanghai around at 3 o'clock on March 9, a new slaughter plant in Shanghai Forte cold storage due to an ammonia pipe burst,, causing the ammonia to a large number of leaks, cold storage near a white mist,, many workers and former to wholesale meat the hawkers Piqiang have ran out. Fire and Rescue Service received a report sent out a number of fire engines, ammonia diluted with water gun. Factory although the timely closure of the pipeline valves, pipe, 50 tons of ammonia, refrigeration workshop to take measures for the recovery of ammonia, until about 6:00, ammonia was basically fugitive out, because the plant away from residential areas farther away, the authorities did not make the decision to evacuate residents,, did not occur in personal injury accident. Shanghai unified installation of residential air conditioning condensate discharge pipe summer season,, air conditioning condensation of water droplets of water is small, but it is one of the reasons that cause neighbor complaints. According to the statistics of the Shanghai Pudong property management department, air-conditioning drip accounted for about 34% of the property of the volume of complaints for the same period. To this end, the Shanghai Pudong New Area,, unified installation of air conditioning condensate discharge pipe, the Department of Real Estate Management estimates the transformation of a 50,000 rn2, 800 households in the district to invest about $ 40,000,, the average household burden of about $ 5O, coordinated Government, property owners tripartite burden,, so let residents bid farewell to worry about the dripping sound,, secure a good sleep. Drip tube to collect the condensate can also be used to irrigate the garden plot. Shanghai released the home central air conditioning maintenance services specification with the growing domestic central air-conditioning market, gradually super warranty period of the home central air conditioning installed in the early disputes growing number of consumers and installation maintenance, Shanghai household appliances industry associations in the Shanghai Price Bureau,, under the guidance of research.

Which the CO, the reaction of lithium carbonate precipitation _2J lithium bromide solution. Rust residue and lithium carbonate precipitate clogging the nozzle with the flow of the solution, affect the solution spray,, absorption rate slows down, resulting in increased * Received date&nbsp;:2005-5-16 evaporator, the refrigerant water overflow evaporator. Solution depending on the different blockage. When the nozzle clogging is not serious, in general, the following methods: 1) to emit a certain amount of distilled water, add the right amount of qualified lithium bromide solution to increase the concentration of the solution. In standard conditions, increase the concentration of dilute solution of 1% to 1.5%, 0.5% to 1% of the concentration of concentrated solution. 2) Open a dilute solution of large absorber valves, increase the amount of spray absorber solution. 3) reduce the cooling water temperature to ensure that in the 30 ~ C or below,, but not less than 20qC. Three kinds of methods can be excluded from the refrigerant water overflow nozzle clogging is not a serious fault, but does not resolve the nozzle clogging. When severe nozzle clogging, these three kinds of approach can not rule out the failure of the coolant water to overflow,, to take the unit cavity chemical cleaning can be resolved. Chemical cleaning steps: 1) washing. Lithium bromide solution discharge unit,, wash with water inside the machine, until the non-bromide ion (available silver nitrate test).

Mass fraction of 7% of the amino sulfonic acid, 1% LX9-001 inhibitor, 0.1% compound surfactant, 1% penetrant, dubbed detergent solution at room temperature, reverse circulation 8 ~ 10h, according to the cleaning of iron ion concentration in the medium to determine whether to complete the cleaning. 3) passivation. Drain the cleaning fluid,, and wash with water to nearly neutral, plus 1% trisodium phosphate, and heated to 80 ~ 90 ℃ cycle 8h emissions. Wash with water to neutral water quality clarification until _3J. 2 absorber present in the non-condensable gas absorber memory non-condensable gas, the constant of the total pressure (evaporation pressure), the partial pressure of the refrigerant vapor reduces the driving force of mass transfer decreases, affecting the absorption rate of the absorber; second is due to the presence of non-condensable gas,, the refrigerant vapor and solution contact area is reduced, and also affects the absorption rate L4J. In this way, resulting in the high side of refrigerant water. Therefore, running water high side of refrigerant in the evaporator cooling capacity drops, you should check the unit's vacuum. According to experience every day pumping a vacuum will be able to solve the non-condensable gas generated due to unit solution to corrosion. If the unit leak, it must be down to check repair. Refrigerant water was contaminated lithium bromide unit phenomenon often occurs in the operation of the lithium bromide solution into the coolant water. The same temperature, saturated vapor pressure of the lithium bromide solution is lower than the vapor pressure of water, the solution around the refrigerant vapor pressure drop, mass transfer driving force is reduced, absorption weakened, the high side refrigerant water,, cooling capacity decreased. Check the coolant water, relative density, if&gt; 1. o4 refrigerant water regeneration. Also, check, analyze and solve the refrigerant water pollution problem. 4 shielded pump damage conveying the coolant water shield pump sealing components is one of the centrifugal pump with a shielded motor. Motor bearings,, non-I is the infiltration of resin, graphite bearing, graphite bearing damage will seriously affect the water throughput, the evaporator basin of water, the water will slowly become more, operation and management personnel should check a refrigerant water per hour Shielded pump current, such as the current increases, graphite bearing damage, and the need to stop to repair or replace the shield pump 5 Conclusion The proposed operation and management personnel in the unit refrigerant water overflow evaporator cooling capacity decreased gradually, according to Figure 1 of the ways Check for and resolve. The same time to check the coolant water shield pump current is increased. 6 References [1] Refrigeration Engineering Design Manual Writing Group.

If the air supply angle is too large, the velocity increases near the wall, air jet caused by the wall convection strengthened part of the air jet directly into the personnel activity area, on the jet stream has been unable to plant the central joining the plant central region can not covered by the air curtain, so the staff activity area will lead to local overheating or local undercooling phenomenon, although the average temperature of the entire heating zone, the vertical temperature difference is small, but the heating zone temperature distribution is very uneven. Winter conditions, the air jet due to the buoyancy effect, the jet trajectory is bent downwards with a range of upwards trend in Figure 9, the figure given in the three different air angle axis at the end of the air jet The center path maps, winter stratification heating axis orbit shape parabola, the air the greater the angle,, orbit the smaller the radius of curvature. Based on the numerical results by controlling the boundary level in the air jet and air jet lap height the air point of view, the specific choice of the air point of view is by changing the air supply angle size, so that the air jet boundary height of less than height of the workspace, and the jet stream lap height above the height of the workspace, so that air jet to form a stable horizontal air curtain at the top of the workspace, and down the hot jet full role in the work area, and the formation of horizontal hot air screen to prevent the lower part of the hot air convection heat transfer. Working height of 3m, seen from the table,, and air an inclination of 10. ,, The height of 4.4m of the boundary under the air jet, the jet stream lap height is 6m, even spray air jet formed a horizontal air curtain, but the Jet border above the working area 2.4m, air the volume covered by the jet is too large, and the air jet at small angles can not fully reach the work area, so that the air jets can not completely role in the work area,, resulting in low average temperature of personnel activities; when the air angle increases , Jet boundary height, gradually approaching the height of the workspace, the jet stream lap height also decreases,, the air jet can gradually reach the personnel activity areas and the formation of hot air to cut off the heating zone and heating zone screen, this time staff activity area air flow to accelerate, with an average wind speed gradually increases, personnel the active region temperature is rising; when the air angle increases to 25. Jet border, height reduced to 2.6m, lower than the height of the workspace, the jet stream lap height of 4.7m,, the interior velocity field, temperature field varying degrees of improvement over the previous three conditions, then air angle within a reasonable range of options: air angle is 30. When the angle of the air supply design conditions,, Jet boundary height of 2.4m, the jet stream to lap height of 4.5m,, height of lower jet stream lap average speed of the personnel activity areas in the comfort requirements of the within the scope of the average temperature of the personnel activity area has basically reached the heating design requirements, and the air jet lap well, to form a stable horizontal air curtain to cut off the heating zone and the non-heating zone, reduce the heat transfer of the lower part of the heat, so for the specific circumstances of this article, the blast angle can choose 25. -30. . 3 Conclusion winter conditions, the layered heating make thermal jet full role in the heating zone, due to buoyancy effects of thermal jet, the non-heating zone temperature higher than the heating zone temperature can be weakened through the airflow organization two intervals of temperature, inhibition of thermal convection in the large space between the upper and lower parts of the winter design calculations, the heat load according to the consider of the full-room air conditioning. Through the analysis of numerical results, stratified air conditioning in winter conditions to achieve satisfactory design requirements, but compared with the summer conditions of energy-efficient, and can not produce a lot of energy efficiency can be controlled with shame boundary level wind jet to select a reasonable air supply angle and jet lap height.
