How does an evaporator work?

1. Heat Exchange and Evaporation Process

An evaporator uses heat from the air to evaporate water, forming a thin film on multiple layers of corrugated fiber (wet pads). As air passes through the water film, it absorbs latent heat, achieving cooling.
2. Negative Pressure and Fan Synergy

The fan creates negative pressure, forcing hot air into the wet pad, improving contact between the air and the water film and accelerating evaporation.
3. Key Influencing Factors

Wind Speed: An appropriate wind speed ensures sufficient air flow while avoiding excessive wind speeds that could blow away the water film.

Evaporation Area: A larger wet pad area provides a wider evaporation area and a better cooling effect.

Relative Humidity: The lower the external relative humidity, the greater the air's moisture absorption capacity and the better the cooling effect.

Company Advantages: Zhejiang Boruis Refrigeration Technology Co., Ltd. utilizes independently developed high-efficiency wet pad materials and energy-saving fan systems, enabling optimal heat exchange efficiency in diverse environmental conditions, meeting the needs of various scenarios, including cold storage and workshops.

What are the different types of evaporators?
1. DL Series (approximately 0°C)

Suitable for locations with high temperature requirements, such as fresh-keeping warehouses and fruit and vegetable refrigeration. Utilizing low-temperature fans and high-efficiency wet curtains, they ensure a stable temperature near 0°C.
2. DD Series (-18°C)

Primarily designed for general cold storage and cold chain logistics, where a freezing temperature of -18°C is required. This series features thicker insulation and a stronger negative pressure system.
3. DJ Series (below -25°C)

For extremely low-temperature requirements in quick-freeze warehouses and ice processing, these units utilize double-layer wet curtains and high-power fans to achieve rapid cooling to -25°C or even lower.

Evaporator Applications and Case Studies
Cold Storage and Fresh Storage

In large fruit storage warehouses, DL-series evaporators, combined with high-efficiency wet curtains, achieve a constant temperature below 0°C, significantly reducing the respiration rate of fruits and vegetables.

Industrial Workshops and Constant Temperature Workshops

The DD-series is widely used in electronic component production workshops, maintaining a low temperature of -18°C and ensuring consistent product quality.

Quick Frozen Food Processing

The DJ-series achieves rapid cooling below -25°C in quick-frozen meat processing plants, significantly improving production efficiency and reducing energy consumption.
