The Condenser with Wind Orifice is an air-cooled heat exchanger designed to dissipate heat from high-pressure refrigerant vapor, converting it into liquid. Its defining feature—strategically positioned wind orifices (airflow channels)—optimizes natural or forced airflow, enhancing heat rejection efficiency. This condenser is widely used in small to medium refrigeration systems where energy efficiency and space-saving are priorities, such as convenience store freezers and residential air conditioners.
The orifices (diameter 15–25mm) are arranged in a staggered pattern across the condenser surface, increasing airflow rate by 25% compared to non-orifice models. This design reduces airside resistance by 18%, allowing natural convection to handle 40% of heat rejection in low-load conditions .
With a heat rejection rate of 5–20 kW (depending on size), the condenser operates efficiently at condensing temperatures of 35–55°C. The aluminum-zinc coated fins (zinc content 15–20%) enhance corrosion resistance, suitable for urban and semi-industrial environments.
Measuring 600–1200mm in height and 400–800mm in width, it occupies 30% less space than traditional air-cooled condensers. The vertical orientation allows installation in narrow spaces (e.g., between building walls).
It functions in natural convection (no fan) for low loads and switches to forced convection (with 200–500W fans) during peak operation, reducing energy consumption by 10–15% in partial-load scenarios.
The condenser withstands maximum working pressure of 3.0 MPa (R410A refrigerant) and test pressure of 4.5 MPa, meeting ASHRAE 15 safety standards for refrigerant systems.
Small-Scale Refrigeration: Used in vending machines and under-counter refrigerators (convenience stores, cafes).
Residential AC: Integrated into window-type air conditioners and mini-split outdoor units.
Marine Applications: Installed in boat refrigeration due to its resistance to salt spray (with optional anti-corrosion coating).
Medical Equipment: Cools laboratory refrigerators (2–8°C) for vaccine and sample storage.
Q: How do wind orifices improve energy efficiency?
A: The orifices channel airflow directly through heat-dissipating areas, reducing air recirculation (warm air re-entering the condenser). This lowers the condensing temperature by 2–3°C, decreasing compressor power consumption by 5–7% .
Q: Can the condenser operate in high-wind environments?
A: Yes. The orifice design includes wind deflectors that prevent excessive air turbulence in winds up to 10 m/s. For coastal areas with stronger winds, a wind shield accessory is available.
Q: What maintenance is required for wind orifices?
A: Orifices should be inspected every 6 months for blockages (dust, debris). Cleaning with compressed air (0.2–0.3 MPa) removes obstructions without damaging the fins. Avoid using water jets, which may bend delicate fins.
