4. การตั้งค่าและการติดตั้ง

Follow these steps for proper installation of the KVR15 Pressure Regulator:

1. การเตรียมระบบ: Ensure the refrigeration system is depressurized and isolated before beginning installation.
2. ที่ตั้ง: Install the regulator in the suction line, upstream of the compressor, and preferably in a horizontal pipe run. Ensure there is sufficient space for service and adjustment.
3. การเชื่อมต่อ: The KVR15 features 5/8 inch ODF (Outside Diameter Flare) connections. Use appropriate brazing techniques for copper tubing. Ensure the regulator is clean and free of debris before brazing. Protect the valve body from excessive heat during brazing by wrapping it with a wet cloth or using a heat sink compound.
4. ทิศทางการไหล: Observe the arrow on the regulator body, which indicates the correct flow direction. Install the regulator so that the refrigerant flows in the direction of the arrow.
5. เข้าถึงพอร์ต: The access port allows for pressure measurement. Ensure the cap is securely tightened after use to prevent leaks.
6. การทดสอบการรั่วไหล: หลังจากติดตั้งเสร็จแล้ว ให้ทำการทดสอบการรั่วซึมอย่างละเอียดในทุกจุดเชื่อมต่อโดยใช้วิธีการตรวจจับการรั่วซึมที่เหมาะสม
7. การอพยพ: Evacuate the system to the required vacuum level before charging with refrigerant.

เครื่องมือที่แนะนำ: Brazing torch, nitrogen for purging, leak detector, vacuum pump, manifold gauge set, pipe cutters, deburring tool, wet rags or heat sink compound.

5. คู่มือการใช้งาน

The KVR15 regulator is designed to maintain a constant evaporating pressure. Adjustment is typically performed during system commissioning.

1. การตั้งค่าเริ่มต้น: The regulator is factory set to a nominal pressure. For specific system requirements, adjustment may be necessary.
2. การปรับความดัน:
   • Remove the protective cap from the adjustment spindle.
   • Turn the adjustment spindle clockwise to increase the evaporating pressure.
   • Turn the adjustment spindle counter-clockwise to decrease the evaporating pressure.
   • Use a pressure gauge connected to the access port or elsewhere in the suction line to monitor the pressure while adjusting.
   • Make small adjustments and allow the system to stabilize before making further changes.
   • Once the desired pressure is achieved, replace and tighten the protective cap to secure the setting and prevent leaks.
3. Access Port Usage: The access port allows for temporary connection of a pressure gauge to verify the regulated pressure. Always ensure the port cap is securely tightened when not in use.

6. การบำรุงรักษา

The Danfoss KVR15 Pressure Regulator is designed for long-term, reliable operation with minimal maintenance. However, periodic checks are recommended.

• การตรวจสอบภาพ: Periodically inspect the regulator and its connections for any signs of leaks, corrosion, or physical damage.
• การตรวจจับการรั่วไหล: Conduct regular leak checks on all brazed connections, especially around the regulator body and access port.
• การตรวจสอบการทำงาน: If system performance issues arise, verify that the regulator is maintaining the set pressure. This can be done by connecting a pressure gauge to the access port.
• การทำความสะอาด: Keep the exterior of the regulator clean. Do not use harsh chemicals that could damage the valve body or seals.

บันทึก: Internal components of the KVR15 are not user-serviceable. If the regulator malfunctions, it should be replaced by a qualified technician.
