US-efficiency refrigeration / freezing of the design and structure

Two electric heaters for defrost, the power of 135 watts. Is a refrigeration evaporator between the aluminum, which is' new kind of squeezed into a plate evaporator, the evaporator surface area than normal, therefore the greater the heat can bear published in 1986 GuldBrandsellandNorgaard that tit: evaporation and condensers to withstand the greater the heat, in normal use, the higher the cooling efficiency of the compressor is turned off, heat transfer is still continuing. Results for higher evaporation temperature and better coefficients. Circuit 2 Circuit 3 shown in Figure 2, between the condenser to freeze around the freezing room layout, around the same refrigerated condenser between frozen furnished. Figure 3 Prototype Zhong Yan hair position. Prototype is equipped with two compressors piston compressors, model is DanlossTFS4A (115 volts,abercrombie et fitch, 60 Hz), semi-j6 · device directly into the air to ensure a higher than normal compressor volumetric efficiency, thermal insulation material in front of already mentioned, the prototype in 1985 the market l: the most efficient of the U.S. sale of 556 liters of the same size as the model shape, with the latter than the former frozen hot material thickness interval 5l mm to 65 mm can be frozen interval of heat thickness 63 mm increments from 85 mm with the result that Q and freezing cold outside the heat transfer between and respectively 22% and 26% reduction of insulation material is polyurethane foam. Control device designed and manufactured in the laboratory, a special electrical control devices,christian louboutin sko, this device can control both the temperature and the freezing cold to ask cyberspace defrost the evaporator. One of the benefits set two compressors are two easy cold temperatures were controlled by the respective regulator. Fourth,ed hardy brasil, the design and structure of the prototype of the freezing chamber set in the upper part of the prototype is a thermal plastic material inside the shell, the shell is a steel plate, and two cold with the door frame can store food,abercrombie outlet, so along the ring reduce the heat exchange part of the prototype is manufactured in the laboratory, in part by the Danish BrdrGramA / S manufacturing. V. Conclusion The prototype m the third brother Bong Hagen Bell Labs Physics Laboratory and California test. The two counties on the prototype laboratory testing r energy physics laboratory on the third prototype made use of the prototype performance test performance test is 4l ℃ room temperature tests conducted, test results show that the prototype has a cooling capacity of Higher Education . Energy consumption of the prototype test is conducted by the United States test key indicators are: the ambient temperature T. Irllh = 32.2 ℃ (90F) of fresh food temperature T = 7.2 ℃ (45. F) freezing temperature T =- I5 ℃ (5. F) by inserting the test method are described: the test of time should be used a defrost cycle, the physical laboratory in the third test will be conducted 48 hours, dysentery try exhausted even q: Eagle Habitat 『Tl l, a 3】 7r ',fred perry paris, frozen T-l know a kind of small, cold limbs I5r bore Song T can be seen from Figure 4, the standard test conditions, the power consumption of 520kWh per year 4 is the third physical network laboratory test results. No laboratory test for the defrost, but take into account the test results dating back a year's electricity consumption and proud defrost _ 『amendment. * 37 * Tests conducted at Bell Labs is the control of the defrost system, each of 2O hours of defrosting time. Tested in strict accordance with DOE standards, the results of insertion of the sail-like power consumption of 554kWh. Calculations show that the consumption tests of Bell Labs and at l3-day power consumption of the defrost cycle, the difference between the test results for the year 18kWh, the revised annual power consumption of 536kWh. Deletion of two laboratories obtained consistent test results. VI, i,-I the structure of the prototype and test results show that we can use the existing insulation technology, base closed heat exchange system compressor and the United States to freeze domestic refrigerating devices hybrid electric consumption reduced to a certain extent . Cost factors: F out improvements to increase the cost of the prototype r: - increase the r a small compressor. - 510 l-type growth than ordinary insulation materials used and metal structural materials. - Added a _ 『evaporators, filters and condenser. - Increase the r at least four pipeline welds. - Manufacture of condensers require more expensive machines. The following sample can reduce the cost of improvements: - focus on saving a condensation - Taiwan condenser. - Due to set up two sets of compression system, so the hair Yan freezing chamber and the fan can choose smaller and cheaper. Asked one by one between the two cold no air circulation, so no need to set the thermostat to control two to ask the question of cold air circulation. . We did not estimate the required mass production of this prototype also increased the cost of J, this part of the cost ultimately depends on the price and the Government's tax and financial subsidies to political section (beam work, Wang Wei translated)
