แดนฟอสส์ 068Z3206 (เท็กซัส2) วาล์วขยายอุณหภูมิ

Danfoss 068Z3206 is an internally equalized thermostatic expansion valve of the TX2 type in the T2/TE2 series, ออกแบบมาโดยเฉพาะสำหรับสารทำความเย็น R22/R407C ที่มี 3/8″ × 1/2″ การเชื่อมต่อเปลวไฟ. ใช้สำหรับควบคุมการไหลของสารทำความเย็นในเครื่องระเหยแห้งของระบบทำความเย็นและเครื่องปรับอากาศเชิงพาณิชย์และอุตสาหกรรม.

1. รายละเอียดรหัสรุ่น

Core Attributes: No MOP (Maximum Operating Pressure) ควบคุม, no pre-installed nozzle (matching nozzle must be selected according to system requirements)

2. พารามิเตอร์ทางเทคนิคหลัก

3. สภาพแวดล้อมการทำงานที่เกี่ยวข้อง
4. System Types: Dry evaporators in commercial refrigeration equipment, ชิลเลอร์น้ำอุตสาหกรรม, และระบบปรับอากาศ
5. สภาพการทำงาน:

Evaporation temperature: -40°C to +10°C

ความกดดันในการทำงาน: Complies with standard pressure ratings for R22/R407C systems

Compatible compressors: Reciprocating and scroll compressors

3. ข้อกำหนดในการติดตั้ง:

6. Engineering Implementation Points
7. Nozzle Selection: Select the appropriate nozzle based on system cooling capacity, evaporation temperature and refrigerant type. If an exact capacity match is unavailable, select the next larger size nozzle.
8. หมายเหตุการติดตั้ง:

Liquid line must be sufficiently subcooled to avoid flash gas affecting valve performance

Powerhead mounting location shall avoid suction line bends and welds

Ensure system cleanliness; a 100μm strainer is recommended to prevent nozzle clogging by contaminants

3. Commissioning Points:

Typical superheat setting: 5-8 เค, adjustable via the top adjustment screw on the valve body

Perform fine adjustment only after the system runs stably, with no more than 1/4 turn per adjustment

8. Key Risk Warnings
9. Refrigerant Restriction: This model is only suitable for R22/R407C and must not be used with other refrigerants such as R410A, R134a, otherwise valve damage or system failure will occur.
10. Equalization Matching: Internally equalized valves are only suitable for systems with low evaporator pressure drop (<0.3 บาร์). For higher pressure drops, the externally equalized TEX2 (068Z3209) must be used.
11. Nozzle Compatibility: Only genuine Danfoss matching nozzles shall be used; non-genuine nozzles may reduce flow control accuracy and service life.

Complete List of Danfoss Thermostatic Expansion Valves

Danfoss thermostatic expansion valves cover multiple series to suit different refrigeration system requirements. Below is a categorized list by core series, รวมถึงรุ่นด้วย, สารทำความเย็น, connection type, equalization type and key features for easy selection and replacement reference.

6. Key Selection Parameter Comparison Table

7. คำเตือนความเสี่ยง & หมายเหตุ
8. Refrigerant Matching: Each model is only compatible with specified refrigerants; improper use causes valve damage and system failure.
9. Equalization Selection: Externally equalized valves must be used when evaporator pressure drop >0.3 บาร์, otherwise flow control accuracy degrades.
10. Nozzle Compatibility: Only genuine Danfoss matching nozzles shall be used; non-genuine nozzles may cause unstable performance.
11. ข้อกำหนดในการติดตั้ง: Powerhead must be firmly mounted on the suction line at the evaporator outlet for good thermal contact.
12. Commissioning Points: Typical superheat setting is 5-8 เค; adjust no more than 1/4 turn each time, and fine-tune only after system stabilization.
