When the ambient temperature and humidity from 25 ℃ to 30 ℃, relative humidity increased from 40% to 90% of the total analysis of water rose from 4.3 liters per l2.4, an increase of 1.88 times. Experiments also showed that water and condensate evaporator defrost water and relative humidity have a great relationship. When the relative humidity is 40%, the stop before the small amount of water condensation evaporator, condensate water analysis only accounted for 30% water, cold water analysis based mainly in the form of cream, this time down defrost timer will not less, and when the relative humidity above 40% (70% and 90%), evaporator condensate water downtime before the larger of the total analysis of more than 75% water, while the amount of frost (defrosting water.) relatively small . In this environment, relative humidity cabinet to run the evaporator frost will not affect the air curtain flow rate,<a href="http://www.edhardy-brasil.com" target="_blank">ed hardy brasil</a>, indicating that the refrigerated display case in the high humidity season (summer) may be appropriate to extend the operation cycle, do not have to frequently defrost. 2.3 cabinet refrigeration system operating conditions and power consumption of experiments show that changes in indoor temperature and humidity will cause the counters placed in the lower part of the refrigeration unit operating conditions change. Table 2 and Table 3, different environmental conditions that run counter refrigeration system condensing temperature and evaporating temperature t = t. ∈; 2425262728293O31 temperature / ℃ Figure 7 samples at different temperature and humidity cabinet to run a cycle (4 hours) Unit power consumption can be seen from the table,<a href="http://www.abercrombiemilanohollister.com" target="_blank">abercrombie outlet</a>, when the ambient temperature rose from 25 ℃ to 30 ℃, the system condensation temperature 4 .9 ~ 7.1 ℃, while evaporating temperature 2.5 ~ 5 ~ C; when the relative humidity from 40% to 90%, the system condensation temperature 3.5 ~ 6.1 ℃,<a href="http://www.fredperry-outlet.com" target="_blank">fred perry outlet</a>, while evaporation temperature 5.1 ~ 7.9 ℃. When the environmental temperature and humidity from 25oC, 40% increased to 30 ℃, 90%, the system condensation temperature l1.0 ℃, while evaporating temperature l0.1 ℃ visible showcase for the installation of air-cooled chiller unit depends on the operating condition changes in the indoor environment conditions, both --,),<a href="http://www.edhardysdanmark.com" target="_blank">ed hardy tøj</a>,)-- depending on ambient temperature depends on both the relative humidity, on the cabinet a great impact on cooling system performance. Experiments also showed that as the system operating conditions change, the system runs the power consumption with the change. Figure 7 shows experimental sample holder in different experimental run a temperature and humidity cycle (4 hours) Unit power consumption (not including the refrigeration unit outside the cabinet, such as lighting, anti-gel and the power consumption of fans, etc.). Experiments show that with the increase of temperature and humidity, the unit's power consumption increases. The figure shows, when the ambient temperature from 25 ℃ to 30 ℃, relative humidity increased from 40% to 90%, the cabinet power consumption increase 2l%, a significant impact on power consumption. 3 Conclusion of the sample container through the above experimental results show that changes in indoor temperature and humidity on the built-in refrigeration units showcase Vertical Open performance great impact. When the ambient temperature from 25 ℃ to 30 ℃, relative humidity increased from 40% to 90%, the inside layers of temperature 6 ~ l0 ℃, increased water evaporator analysis of 188-fold increase in power consumption 2l %. Performance of such a large change in the showcase, showcase designers and users need to attract much attention. Showcase for designers to improve the structure, system configuration and operation control methods, improving the overall performance showcase, to meet the changing needs of environmental temperature and humidity. At the same time for the user to select and maintain low indoor humidity place to find the temperature distribution inside the display case, according to the rational use of seasonal climate display and adjust the food storage area and run cycle, can reduce the number and cabinet defrost temperatures, to reduce energy consumption and guarantee the quality of the food on display.
