4. ترتیب او نصب کول

Installation of a thermal expansion valve requires specialized knowledge of refrigeration systems, including refrigerant handling, brazing, and system evacuation. It is strongly recommended that installation be performed by a qualified and certified refrigeration technician.

4.1 د خوندیتوب احتیاطونه

• Always disconnect power to the ice machine before beginning any service work.
• مناسب شخصي محافظتي تجهیزات (PPE) واغوندئ، په شمول د خوندیتوب عینکې او دستکشې.
• Handle refrigerants with extreme care. Refer to local regulations for proper handling and disposal.
• ډاډ ترلاسه کړئ چې د کار ساحه ښه هوا لري.

4.2 General Installation Steps (for qualified technicians)

1. د یخچال بیا رغونه: Safely recover all refrigerant from the system using proper recovery equipment.
2. Remove Old TXV: Carefully unbraze or unthread the old thermal expansion valve and sensing bulb.
3. Prepare New TXV: Ensure the new TXV is the correct model and free from damage.
4. برزنګ: Braze the new TXV into the liquid line, taking care to protect the valve body from excessive heat. Use nitrogen purge during brazing to prevent oxidation.
5. د سینسنګ بلب نصب کول: Securely attach the sensing bulb to the evaporator outlet line, ensuring good thermal contact. Use the provided clamps یا تسمې.
6. د لیک ازموینه: Pressurize the system with nitrogen and perform a thorough leak test using an electronic leak detector or soap bubbles.
7. ایستل: Evacuate the system to a deep vacuum (typically 500 microns or less) to remove all non-condensable gases and moisture.
8. د یخچال چارج کول: Recharge the system with the correct type and amount of refrigerant as specified by the ice machine manufacturer.
9. System Start-up and Adjustment: Start the ice machine and monitor superheat and subcooling to ensure proper TXV operation. Adjust as necessary.

۴. د کار اصول

The thermal expansion valve controls the flow of refrigerant based on the superheat at the evaporator outlet. The sensing bulb, filled with a charge similar to the system's refrigerant, detects the temperature of the suction line. As the temperature changes, the pressure within the bulb changes, which in turn acts on a diaphragm inside the TXV. This diaphragm movement adjusts the valve's orifice, allowing more or less liquid refrigerant to enter the evaporator. This precise control ensures that the evaporator coil is fully utilized without allowing liquid refrigerant to return to the compressor, which could cause damage.

6. ساتنه

The Scotsman 16-1144-21 Thermal Expansion Valve Kit is designed for reliable operation with minimal maintenance. However, regular inspection of the overall refrigeration system is recommended to ensure optimal performance and prevent premature component failure.

• د سیسټم پاکوالی: Ensure the refrigeration system remains clean and free of contaminants, which can clog the TXV orifice.
• Sensing Bulb Contact: Periodically check that the TXV sensing bulb maintains good thermal contact with the suction line. Loose or improperly insulated bulbs can lead to erratic valve operation.
• د لیک چکونه: Include the TXV connections in routine leak checks of the refrigeration system.
• مسلکي معاینه: Have a qualified technician perform annual inspections of the ice machine's refrigeration system, including TXV performance.

7. ستونزه حل کول

Issues related to a thermal expansion valve often manifest as problems with ice production or overall system efficiency. Troubleshooting should only be performed by a qualified refrigeration technician.
