- Dispose of old filter driers and refrigerants according to local regulations.
3. Konec produktuview
The Danfoss DCL162 Filter Drier (Model: 023Z5007) is a hermetic filter drier designed for liquid line applications in refrigeration and air conditioning systems. It features a solid core composed of 80% molecular sieve and 20% activated alumina, optimized for adsorbing system moisture and capturing acids and other contaminants. Its universal design allows it to serve as a direct replacement for many existing driers.
Klíčové vlastnosti:
- Univerzální kompatibilita: Suitable for most refrigeration, air conditioning, and heat pump units.
- Robustní konstrukce: Features solid bronze inlet and outlet flare connections.
- High Performance Core: Effectively removes moisture, acids, and solid contaminants.
- Wide Refrigerant Compatibility: Works with R1234Yf, R134A, R290, R22, R407C, R404A, R507A, R600, and many others.

4. Instalace a nastavení
The Danfoss DCL162 Filter Drier is designed for installation in the liquid line of refrigeration and air conditioning systems. Proper installation is crucial for optimal performance and system longevity.
Kroky instalace:
- Odtlakování systému: Before beginning, ensure the refrigeration system is completely depressurized and isolated. Recover all refrigerant according to environmental regulations.
- Vyhledejte místo instalace: Identify the appropriate location in the liquid line, typically between the condenser and the expansion device.
- Cut and Prepare Tubing: Cut the existing liquid line tubing cleanly. Ensure the ends are deburred and free of debris.
- Connect Filter Drier: The DCL162 features 1/4" flare connections. Connect the filter drier to the liquid line using appropriate flare nuts and ensure a tight, leak-free seal. Use a backup wrench to prevent twisting of the drier body.
- Direction of Flow: Observe the flow arrow on the filter drier body to ensure it is installed in the correct direction of refrigerant flow.
- Evakuace: After installation, evacuate the system to a deep vacuum to remove any non-condensable gases and moisture.
- Systém dobíjení: Doplňte systém správným typem a množstvím chladiva podle pokynů výrobce systému.
- Kontrola těsnosti: Perform a thorough leak check on all connections using an appropriate leak detection method.
Poznámka: The filter drier should be installed in a location that allows for future access for inspection or replacement.
5. Provoz
The Danfoss DCL162 Filter Drier operates passively within the refrigeration system. Its primary function is to continuously remove moisture, acids, and solid contaminants from the refrigerant as it circulates through the liquid line. This action protects sensitive system components, such as the compressor and expansion valve, from damage and ensures optimal system performance and longevity.
There are no user-adjustable settings or operational controls for the filter drier itself. Its effectiveness is maintained as long as its core is not saturated with contaminants or moisture.
6. Údržba
Filter driers are generally considered maintenance-free components. However, their lifespan is dependent on the cleanliness of the system. Regular system checks are recommended to monitor the overall health of the refrigeration circuit.
Pokyny pro výměnu:
- New System Installation: Always install a new filter drier when installing a new refrigeration system.
- System Repair: Replace the filter drier whenever the system has been opened for major repairs, especially after a compressor burnout or if there is evidence of moisture or acid contamination.
- Známky nasycení: If signs of moisture (e.g., ice formation at the expansion valve) or acid (e.g., discolored oil) are present, the filter drier may be saturated and requires immediate replacement.
- Tlaková ztráta: A significant pressure drop across the filter drier can indicate a clogged core, necessitating replacement.
Důležité: Always replace the filter drier with a new, appropriately sized unit. Do not attempt to clean or reuse old filter driers.
7. Řešení problémů
While the filter drier itself is a passive component, issues related to its performance can manifest as broader system problems. Here are some common indicators and potential causes:
| Příznak | Možná příčina | Řešení |
|---|---|---|
| High head pressure / Low suction pressure | Partially or fully clogged filter drier | Replace filter drier. Check for system contamination. |
| Ice formation at expansion valve | Moisture in system, saturated filter drier | Replace filter drier. Evacuate and recharge system. |
| Compressor failure (acid burnout) | Acid contamination due to moisture, saturated filter drier | Replace compressor and filter drier. Perform thorough system cleanup. |
| Snížený chladicí výkon | System contamination or moisture affecting efficiency | Inspect filter drier, replace if necessary. Check for other system issues. |
If troubleshooting steps do not resolve the issue, consult a qualified HVAC/R technician.
