使用步进马达制冷控制阀费用的直接和间接节约

DIRECT AND INDIRECT SAVINGS USING STEP MOTOR REFRIGERANT CONTROL VALVES

在空调和制冷行业追求更高效率和使用不同制冷剂时 ,各类电子控制器和电动阀正前所未有地大量使用。电动阀几乎可以在制冷系统中任何一个地方使用 ,而并不局限于膨胀阀。直接费用的节约 ,通常是由于电动阀根据冷凝压力和回气压力变化作出调整来实现的。间接费用的节约 ,通常是通过冷柜空间内温度的稳定 ,增加食品的寿命来获得的。

As the industry moves toward greater efficiency and the use of different refrigerants, electronic controls and electric valves are being used more often. The benefits of the of the electric valves can by realized in almost every part of the system, not just as expansion valves. Direct benefits accrue from the ability of the valves to operate with varying head and suction pressure. Indirect benefits result from increased product life due to the stability of the temperature in the refrigerated space.
