The Ranco Ice Bank Control O18-100 is a mechanical device designed to sense and regulate the thickness of ice in an ice bank refrigeration system. It consists of a main control unit and a capillary tube with a sensing bulb.

รูปที่ 1: Ranco Ice Bank Control O18-100. The image displays the gray main control unit with the Ranco logo and a visible adjustment screw. Below it, a coiled copper capillary tube extends to a metallic sensing bulb.

ส่วนประกอบหลัก:

• หน่วยควบคุม: The main housing containing the electrical contacts and adjustment mechanism. It is gray and measures approximately 2 5/8 inches in height, 1 7/8 inches in width, and 3 1/4 inches in depth.
• หลอดแคปิลลารี: A thin copper tube connecting the control unit to the sensing bulb.
• หลอดไฟตรวจจับ: A water-filled bulb that detects the ice thickness. It contains transmission fluid which expands or contracts with temperature changes, transmitting pressure through the capillary tube to the control unit.
• Adjustment Screw: Located on the front of the control unit, used to set the desired ice thickness.

การติดตั้งและการตั้งค่า

Proper installation is crucial for the accurate and reliable operation of the Ranco Ice Bank Control. Consult a qualified refrigeration technician for installation.

1. การตัดการเชื่อมต่อไฟฟ้า: Ensure all power to the refrigeration system is disconnected at the main breaker before beginning installation.
2. Mounting the Control Unit: Mount the main control unit in a location that is easily accessible for adjustment and wiring, but protected from physical damage and excessive moisture. Use appropriate fasteners for secure mounting.
3. Sensing Bulb Placement: The sensing bulb must be positioned within the ice bank tank where ice formation occurs. It should be submerged in the water and located at the desired ice thickness level. Ensure the capillary tube is routed carefully to avoid kinks or damage.
4. สายไฟฟ้า: Connect the control unit to the refrigeration compressor's control circuit according to the wiring diagram provided with your specific refrigeration system. The Ranco O18-100 acts as a switch to cycle the compressor based on ice thickness. Refer to local electrical codes for proper wiring practices.
5. การตรวจสอบระบบ: After wiring, restore power and verify that the refrigeration system operates correctly.

คำแนะนำการใช้งาน

The Ranco Ice Bank Control O18-100 is designed for automatic operation once properly installed and adjusted.

1. การปรับแต่งเบื้องต้น: The adjustment screw on the front of the control unit allows for fine-tuning the ice thickness. Turning the screw clockwise typically increases the desired ice thickness, while turning it counter-clockwise decreases it.
2. Monitoring Ice Thickness: After initial adjustment, monitor the ice thickness in the bank over several cycles. Make small adjustments to the screw as needed until the desired ice thickness is consistently achieved.
3. หลักการทำงาน: As ice forms around the sensing bulb, the water inside the bulb freezes and expands. This expansion creates pressure in the transmission fluid, which is conveyed through the capillary tube to the control unit. When the pressure reaches a preset point (corresponding to the desired ice thickness), the control unit opens a switch, stopping the compressor. As ice melts, the pressure decreases, and the control unit closes the switch, restarting the compressor to build ice again.

การซ่อมบำรุง

The Ranco Ice Bank Control O18-100 requires minimal maintenance. Regular checks can help ensure its longevity and proper function.

• การตรวจสอบภาพ: Periodically inspect the control unit, capillary tube, and sensing bulb for any signs of physical damage, corrosion, or leaks.
• ความสะอาด : Ensure the sensing bulb is free from excessive scale or debris that could impede its ability to accurately sense ice formation. Clean gently if necessary.
• การเชื่อมต่อไฟฟ้า: Annually, or as part of routine system maintenance, verify that all electrical connections are tight and free from corrosion.
