As a starting point in order to reduce overall transportation costs, improve efficiency, the use of computer technology (including geographic information systems technology and optimization techniques),, established distribution scheduling, delivery orders assigned to the vehicles to be used. (4) the temperature of the vehicle low temperature freezers more intuitive and remote monitoring technology for business managers tuna quality real-time remote control may make the system an increase of the temperature rise due to automotive products, as soon as possible on the way off-site trade function. (5) intelligent scheduling techniques to create a distribution schedule for the vehicle to reach the distribution point, so that the most reasonable time frame, improve service quality. Provides drivers with driving directions to ensure that the vehicle driving away the best, achieve the purpose of reducing transportation costs. Using intelligent scheduling technology provides driving directions to get rid of the over-reliance on a single row and transportation process for dispatchers and drivers experience, experienced drivers no longer be forced to complete these tasks. Between drivers also can be good for the swap, but also eliminates the trouble of some drivers do not often send regional road conditions are not familiar with. To break the fixed mode of delivery route, according to the specific orders of distribution, reduce vehicle Kongshi rate, improve the utilization of the enterprise as a whole vehicle. (6) the establishment of intelligent marketing network, and hierarchical control and management and marketing services. May be the case, the driver at the same time marketing staff, to improve the efficiency of the staff. Several issues need to be addressed (1) to establish a standardized system for tuna cold chain logistics. Ultra-low temperature tuna logistics of logistics requirements is different from ordinary products, processing, storage and transport difficulty, therefore, in our country is about to hot tuna market on the eve of the standardization system to be established as soon as possible. Especially rough in the capture of tuna,, the average temperature cooling,, freezing of average temperature and average temperature thawing process and other aspects should be standardized in order to improve the quality of the tuna processing and storage. To be in the low temperature cold storage management and processing procedures to speed up technical training. (2) internal resource optimization and integration of the corporate development of the logistics system. According to the size and needs of different enterprises, designed to meet the characteristics of the enterprise logistics system, to develop and standardize the management system. Existing aquaculture enterprises in China to the lack of appropriate transport enterprises,, and to a certain degree of difficulty in the establishment of aquatic cold chain logistics. Fisheries Group from the building and become bigger and stronger set of aquatic products production, processing, transportation, sales as one can contend with the modern international competitiveness point conditional enterprise groups should consider the acquisition or merger-related transport enterprises . By large-scale logistics enterprises optimize the delivery, in order to reduce production costs in the corporate group as a whole to achieve the purpose of cost of sales and logistics costs. (3) research and development of logistics industry of China's ultra-low temperature facilities and equipment of fish processing machinery manufacturing standards. China cut of tuna raw material,, get meat rate is relatively low, mainly due to mechanical serrated loss part of the raw materials. If you Similarly,, in the development of tuna thawing equipment, packaging equipment,, door to door airbag the SPIDERS devices as well as cold storage, freezing cabin, refrigerated containers and refrigerated cabinet making machinery, manufacturing, materials and manufacturing processes, there are great prospects for development. (4) the establishment of a tuna product quality and refrigerated processing facility operating quality monitoring network. The start of the tuna market in China, will greatly enrich our high-quality deep-sea aquatic food will give the tuna manufacturers bring considerable economic benefits. On the other hand, need to take full advantage of the limited resources of tuna and tuna market mechanisms need to establish a macro-control. For tuna product quality supervision and inspection agencies should as soon as possible into the production and storage of transport enterprises, technical training, technical guidance and quality inspection,, so that people eat tuna products to the health and safety. 4 References [1] Zhang Xiaoping.

Healthy air conditioning urgent national standard Beijing Municipal Health Bureau shortly before the market, clearly marked with disinfection, sterilization, antibacterial efficacy of air conditioners,, refrigerators carry out the sampling, the results surprising: the sterilization efficacy of publicity misnomer. According to the State Council Development Research Center of the market, according to a recent survey,, 88.6 percent of consumers use the health of air conditioning Experts believe that many manufacturers exaggerate and hype the health of its air-conditioning technology. Health technology trends seminar on It is reported that from July 2003, the Domestic air conditioning companies have to develop the rural market, domestic air conditioner market in major cities there have been signs of saturation, prompting air conditioning companies the main focus of the air-conditioning sales have from the city to rural. The situation of the domestic air conditioner industry from August last year, Air Conditioning Refrigeration beginning of the year 2005 is not optimistic,, especially in the domestic air conditioner sales fell nearly 20 percent in August and September last year. In stark contrast, the rural township market air-conditioning sales but more than 50% increase. According to the statistics show that last year, domestic air conditioning sales of 30 million units, the provincial capital cities and other large cities, medium cities and rural towns market each one. U.S. air-conditioning will start this year, the township air-conditioning penetration plans, investment in the next three years, million to BU in the rural township market, tens of thousands of sales outlets,, to seize 30% of the rural township market goals. The United States this year,, Gree, Haier air conditioning giant began to focus on rural township market. - (More than by the special correspondent fee greater odds reported the) <br /> &lt;/pre&gt; &lt;/td&gt; &lt;/tr&gt; <br /><br />Simplified Chinese Spanish Traditional Chinese Related articles:<br /> <ul><br />  <br /> </ul><br />Related articles：<br /> <ul><br /> <br /> </ul> <p>Related articles： </p> <ul> <li></li> <li></li> <li></li> </ul> <h2> <span class="mw-headline" id="air_conditioning_enthalpy_difference_room_increasing_functio"> air conditioning enthalpy difference room increasing functio </span></h2> <br /> &lt;tr&gt; &lt;td&gt; <pre> &lt;br&gt; air conditioning enthalpy difference room increasing function of the small central air conditioning unit performance testing transformation program &lt;br&gt; </pre> &lt;/td&gt; &lt;/tr&gt; <br /> &lt;tr &gt; The main reason for &lt;td&gt; <pre> &lt;br&gt; secondary control is adjustable electric heating power than workers from 25-100 cooling capacity of the adjustable and strong.

Table 3 dry coil air conditioning air handling mode state point parameters calculated by the state point parameters and the psychrometric chart, the results are as follows: the total air volume (O-N): 11000m / h fresh air: 1100m / h hot wet: ~ = the 16250KJ/Kg the amount of air conditioning and refrigeration (w-L1): 22.94KW air-conditioning cooling capacity (C-O): 6.76KW air conditioning cooling capacity: 29.7KW air conditioning heat (L1 P): 3.36KW2-2 energy analysis of dry fresh air mixed with return air to the indoor offset a table of cold wet load in the fresh air of indoor air processing mode. Cycle units do not bear the dehumidification process,, just fine-tune the room dehumidification cycle unit also has a dehumidification process. Low air humidity, the temperature inside. High temperature, need to be reheated in the usual way, a lot of hot and cold offset a return air system and secondary air system load difference is that heat caused a lot of energy waste. North steam humidification, a return air system has a larger thermal process. The secondary heat source grade require a higher energy consumption; southern region using multi-electrode Wind (fixed secondary air ratio of 1:1) system sometimes need a reheat type humidification, energy consumption, the humidifier is easily damaged. However,, dry coil air conditioning air fine-tuning process, but then less heat. Gas processing mode to avoid this situation: excessive handling by the new air handling units (rev 56) 56 Refrigeration and Air Conditioning 2009 Kui by the above procedure can easily get a discrete PID step response curve. Figure 6 Figure 7 when the heat exchanger working fluid outlet temperature is 6O ℃ mutation set temperature step response curve for 5 ~ C; the contrary,, is when the outlet water temperature is 5 ° C,, the set temperature is 65 ° C when the step response curve. From the two curves we can see the script, good running condition. 4 Conclusion Through the above based on the Kingview discrete control of the heat exchanger PID design, you can draw the following conclusions: After the above-mentioned script language for control purposes, the discrete PID control of the heat exchanger outlet water temperature; Kingview user interface simple, friendly,, and the system to achieve a high level of automation. The control design has been applied in the industrial heat exchanger water temperature control to meet the technological requirements of production, has some promotional value.
