(71 sample, put through the open l: 1 into the display of the total heat rejection is calculated into the formula for the common form of heat. the application of force for heat transfer calculation assumes that the premise is first to identify the heat transfer coefficient K, which can be tested to OK. heat shield through the heat reject incoming display the following formula to calculate the Q3 = KF (tb - t.) 【<img src="http://picsrv.fora.pl/images/smiles/icon_cool.gif" alt="Cool" border="0" /> where: K - heat shield heat transfer coefficient, w / (MK) F ~ - heat shield area, M club to achieve the display of the internal air circulation, fans set f takes refrigerated display area, the work of fan motor heat. dlf its closure smaller.

This type of solution,<a href="http://www.polo-fredperry.com" target="_blank">fred perry singapore</a>, the key is K determination. Third, the load distribution to discuss the level of air curtain with pepper refrigerated display case refrigeration load distribution Ng, first you must know the cold wins B'kg / csMb07n quote 0.O.040.03 Ⅱ .020.0 li | 1 t01020-℃ cold air curtain ring area of ​​3 units in Hong Kong through the flow of ambient air temperature tJ stern relationship with the consumption of cold air curtain. by the type (2J know, the cold air curtain with the infiltration of air between the heat of the solution,<a href="http://www.ralphlauren-uk.net" target="_blank">ralph lauren uk</a>, must understand environment within the unit when you hear the quality of the air curtain with the cold air exchange capacity G. actually air quality with the cold air curtain is a curtain of air to cold air infiltration process,<a href="http://www.toryburchukshoes.com" target="_blank">tory burch uk</a>, so G is the cold air curtain air infiltration traffic. For the unit area of ​​cold air curtain, air infiltration flow rate with temperature (b - t) relationship as 3 3 / 23 * 1993 Refrigeration said. cold air flow at a low temperature range close to the edge of moving the body glistening characteristics. glistening in the cold air moving in fact does not exist in a mixed situation. It can be seen, there are two stable areas. In tb-t. = lO ~ l2 ℃, the amount of air infiltration throughout almost unchanged at t0> ; 25 ~ relaxation ℃, the air closer to the flow of glistening prisms, between them there is a rapid change of air infiltration capacity of the district town. Yi is due to a change in the flow of the election, caused by a rapidly changing region.

The heat shield about the heat transmission cabinet l0% to 15%. Showcase cold air curtain cooling consumption in a large proportion of container in the design need to pay enough attention to its structure. In fact, air humidity on refrigerated display of 24 * La Chong 3 / 1993 cabinet cooling consumption greatly. When the air temperature from lO% ~ 35% increased to 50% ~ 7O%, the refrigerated display an average increase of axial cooling load required to 2O% ~ 30%.

This paper has proposed for level of cold plate refrigerated display screen of the cooling load calculation formula together with the statement required by similar foreign products are basically the same cooling load. 2. Zhou analysis results show that the cold wind screen in the cooling load in the refrigerated display case a large percentage of , its value can be reached 5O% ~ 7O%. 3. ambient air humidity on the cooling load display case under discussion have a great impact. ● test [1] Yang Chuan cooked World Science Higher Education Press drill the well-being .1984 ~ (2 ] TYLER. product samples.
