Post subject: christian louboutin Thermal Performance of refrige
Thermal aging refrigerator car
I4898303.7 × 10249087.653.9 × 10Bl349.1886394 × 105445182449.084.97378x10_549.096.12428x】】 5 054/1993 Refrigeration Model Figure 2Bl9 air tightness of the process of applying curve l - B_n44518I No car; 2 - B19445182 No. 3 car from the table the results can be seen: 1. 6 years after two track cars use air tightness targets have increased in value, an average annual increase rate of the two vehicles 0.4% ~ 6.6% 3'2l through factory repair, a car with air tightness improved, and the other one then it increased, analyze its causes, is 44518l car repair in the upper right corner outside the front door, a side of Alice, a serious leak, been corrected in the factory repair, so a small leak before repairs than Works , and 445,182 car door properly, but the wet insulation, air tightness and therefore close to the former factory car repair, Overhaul due in by thousands of dry insulation, so plant after leak repair but increased j3 t test results from the Look, doors, ventilation mouth, drains and other moving parts of the state a great impact on air tightness, air tightness is the vehicle to the deterioration of t factors. __F And wet insulation material on the film has some tightness Xun, wet insulation can increase the leakage resistance, reducing leakage. Third, the comprehensive ability of cooling heat transfer performance of the deterioration of the body (including insulation and air leaks and a combination of cooling performance to the performance of the set conditions for the cooling capacity. Cooling capacity of cargo transportation is a direct indicator of quality. In vehicles in the use of integrated heat transfer coefficient due to gradually increase cooling capacity and cooling the gradual decay machinery, refrigerated vehicles in the conditions set down l6-F, Journal of Refrigeration 4 / 1993 temperature capacity will be greatly reduced, the performance of the car is not up to to the design of the low value of the goods shipped directly Wei Association of the quality. Therefore, the cooling capacity of refrigerated trucks integrated thermal properties important indicator of aging. 'in the tracking test, the decision-making unit of the trouble, only provides for a B. 451S2 No. the cooling capacity test car, which is really left feeling. In this test, but machines do a cool, dual cooling and additional heat load of the three conditions. additional thermal stress test was to test the value and the refrigeration unit when the K F lowering time cooling capacity can be achieved at low temperature cold heat load added is determined by: Q Zhu F △ t [K Pass (1 + v) a K Banquet] (1J-type vehicles, one by one in the F surface area of the geometric mean , F a 192.21ri1; △ t - design assignment required temperature difference inside and outside the car. △ t = 58KK - design requirements of the body heat transfer coefficient, K a 0.523W / (m · K): v - - In addition to deterioration of heat transfer coefficient outside the influence of other factors,

, taking 0.1; K - measured heat transfer coefficient, K Huan = O.276W / (ri1 · K) the relevant parameters into (1), we considered Q = 3 .34 kW. cooling capacity test results in Table 4. B1 ~ ~ 45182 No vehicle cooling capacity test results in Table 4 are reduced down to O ℃ 10 ℃ by a sub-l5 ℃ lower temperature conditions of the minimum time required 『white j (h) take time (h) take time (h) Time (h) and outdoor temperature +4 O ℃ 8132I single cooling (flail .42 ℃) BU 1038 ℃) (1489 40 ℃ I.53595 double cooling (+ O59 ℃) Blake 961 ℃) (15.12U,) (I9I ℃) Additional 3356kW Dual heat load of work, 3h after the temperature inside the vehicle picked up from the l9I ℃ to 164I ℃, and At this temperature, additional heat load of wave action can be seen from Table 4: l outside temperature +40 . Additional heat load test,

, dual mechanism of cold can only reach a l6.4 ℃, less than a l8 ℃ up to normal use requirements; 3. do not go inside temperature drop is mainly due to poor performance at low temperature refrigerator, but the cooling also affect the system configuration properly. Fourth, vehicle maintenance and recovery of thermal performance of design tasks in the book, refrigerated trucks,
