display cooler dual refrigeration technology solves the technical problems that are difficult to overcome by a single refrigeration method, so that there is no cooling blind zone in the cabinet. The 500mm super wide shelf provides customers with a larger effective display area and more inventory. Osram's special lamp tube placed at the front of each shelf enhances the display effect of the items in the cabinet. The display cooler integrated foaming and firm steel frame foundation make the cabinet better in heat preservation performance and stronger in structure.     The color steel plate cabinet with strong corrosion resistance increases the service life of the cabinet. The display cooler fully transparent glass side panels make the items in the cabinet clear at a glance and enhance the display effect of the items in the cabinet. The digital thermostat controlled by the microcomputer makes the temperature control of the items in the cabinet more accurate and the system more energy-saving. display cooler The cooling load of the refrigeration room is the heat that must be taken out of the refrigeration room per unit time; or the cooling capacity that the refrigeration room obtains from the chiller per unit time. The calculation of the refrigeration load of refrigeration room is to determine the cooling equipment load and mechanical load of each cold room correctly and reasonably. The cooling load of the cold room is not constant throughout the year, and its load size is affected by many aspects. For example, the changes in the external environment temperature, the amount of food storage in the cold room, the difference in the amount of cold processing of food in the off-season and peak seasons, and many factors in the operation and management methods. Usually, the calculation of the cooling load is one of the first tasks in the design of the cold storage refrigeration device. One. Therefore, it is very important for the refrigeration design to reasonably determine the refrigeration load of the cold room. 　　 display cooler When calculating the cooling load, the most unfavorable working conditions should be considered. This is the principle of outdoor calculation. For rooms that transfer heat from indoor to outdoor, the outdoor temperature in the hot season should be considered; while for rooms that transfer heat from outdoor to indoor, the outdoor temperature in cold seasons should be considered. The cold rooms of cold storage are mostly of the type that transfers heat from indoor to outdoor. Due to geographical differences, different areas have different outdoor temperatures; even in the same area, the temperature varies in different seasons, and the temperature changes over the years are also quite different. Therefore, you cannot simply take the temperature at a certain moment as the outdoor temperature.     Because the time of continuous occurrence of extreme temperature is unusual, and the domestic cold storageThe thermal inertia of the advanced maintenance structure is large, and its attenuation is large, and it will be delayed or separated in the insulation layer of the maintenance structure, and will not cause the temperature change of the cold storage. If you press the extreme maximum temperature, it will lead to the selection of high-power machinery and equipment, resulting in energy waste, which is unreasonable. The short-term unstable factors can be ignored and the heat transfer can be regarded as stable. When calculating the heat flow of the warehouse enclosure structure,   summer air conditioning daily average temperature   should be used.
