\t\t\t\t\t\tIndustrial chillers are refrigeration devices that assemble refrigerators, condensers, evaporators, expansion valves, control systems, and switch boxes on a common base or frame. According to the heat rejection method of the unit, it can be divided into water-cooled and air-cooled chillers. The latter adopts heat pump circulation and is welcomed by users. After fully considering the above factors, what should we pay attention to when choosing a chiller?<\/span><\/p>\n

\n\t\"\"\n<\/div>\n

The main configuration is:<\/strong><\/span>
Compressors, electrical components, water pumps, evaporators, condensers, high\/low pressure controllers, high\/low pressure gauges, LCD thermostats, expansion valves, antifreeze switches, hand valves, and fans. Screw chillers and high-precision constant temperature circulating chillers are trusted by well-known international and domestic vacuum instruments, analytical instruments, and other manufacturers.<\/span><\/p>\n

W<\/strong>ater circulatory system:<\/strong><\/span>
First inject a certain amount of water into the water tank of the chiller, cool the water through the chiller refrigeration system, and then send the low-temperature cooling water to the equipment that needs to be cooled by the water pump. The chilled water will take away the heat and increase the temperature before returning to The water tank achieves the cooling effect. The cooling water temperature can be automatically adjusted according to requirements, and long-term use can save water. Therefore, the chiller is a standard environmentally friendly and energy-saving equipment.<\/span><\/p>\n

When choosing a chiller, you should also pay attention to the following points:<\/strong><\/span><\/p>\n

1. Geralmente, s\u00e3o adequadas 2 a 4 unidades de refrigera\u00e7\u00e3o, 2 para sistemas pequenos e m\u00e9dios, 3 para sistemas maiores e 4 para sistemas extragrandes. Deve ser considerada a possibilidade de backup m\u00fatuo e de comuta\u00e7\u00e3o entre unidades. Podem ser utilizados esquemas de combina\u00e7\u00e3o com diferentes tipos e capacidades de unidades na mesma sala de computadores para poupar energia. Entre as unidades que funcionam em paralelo, deve ser selecionada pelo menos uma unidade com maior grau de automatiza\u00e7\u00e3o, melhor desempenho de regula\u00e7\u00e3o e funcionamento de elevada efici\u00eancia em carga parcial.<\/span><\/p>\n

2. O coeficiente de refrigera\u00e7\u00e3o COP do frigor\u00edfico el\u00e9trico \u00e9 mais elevado do que o coeficiente t\u00e9rmico. No entanto, cada tipo de unidade tem as suas pr\u00f3prias carater\u00edsticas e utiliza os seus pontos fortes.<\/span><\/p>\n

3. Para a fonte de frio de um sistema centralizado de grandes dimens\u00f5es, \u00e9 aconselh\u00e1vel escolher um chiller com uma estrutura compacta, de dimens\u00f5es reduzidas, com compressor, motor, condensador, evaporador e componentes de controlo autom\u00e1tico montados na mesma estrutura. Para sistemas pequenos, devem ser utilizadas unidades de condensa\u00e7\u00e3o de compress\u00e3o evaporativa direta.<\/span><\/p>\n

4. A ind\u00fastria de equipamento de refrigera\u00e7\u00e3o do meu pa\u00eds desenvolveu-se rapidamente na \u00faltima d\u00e9cada e a maior parte do desempenho do produto est\u00e1 pr\u00f3ximo do n\u00edvel avan\u00e7ado internacional, especialmente os refrigeradores de pequena e m\u00e9dia dimens\u00e3o, que s\u00e3o completamente compar\u00e1veis aos produtos importados e t\u00eam vantagens incompar\u00e1veis em termos de pre\u00e7o. Por conseguinte, nas mesmas condi\u00e7\u00f5es, os refrigeradores nacionais devem ser selecionados em primeiro lugar.<\/p>\n
