The evaporative cooler is the heat exchanger of the fan coil unit, its performance determines the unit's ability to transfer cold (or heat) and its impact on airflow. This equipment is commonly found in most air conditioning systems.

The aluminum fin of the air conditioner's heat exchanger features a double-bend louver design, ensuring turbulent air flow for enhanced heat exchange efficiency. The aluminum fins of the heat exchanger undergo a rigorous three-step cleaning process at the factory: ultrasonic cleaning with metal cleaner, followed by a clear water rinse, to ensure no residue remains on the fins. This guarantees smoother air flow and fundamentally guarantees the reliability of the heat exchange.

The Function of the Condenser:

Utilize refrigerant to absorb heat within the cooling coil, gradually reducing the temperature of the space being cooled.

Air-cooled coil of the air handling unit cools the air passing over the heat exchanger fins by circulating chilled water (refrigerant water) inside. The fan then delivers the cooled air to the occupied space for cooling. The chilled water, carrying the absorbed heat, returns to the refrigeration unit through the return pipe of the coil, where it releases the heat, cools down, and is then sent back to the coil to absorb heat and cool the air passing through, continuously cycling.

The finned air heat exchangers with chilled water as the medium are generally referred to as surface coolers, commonly using Ф16 copper tubes (with a hole spacing of 38 and a row spacing of 33). In recent years, surface coolers with Ф12.7 copper tubes (hole spacing of 31.75, row spacing of 27.5) have also gained wide application.

The evaporator is manufactured using mechanical胀管 technology, ensuring excellent heat exchange performance.

The condenser header material can be galvanized pipe, copper pipe, or stainless steel pipe; the condenser fins can be standard aluminum foil or hydrophilic aluminum foil; the condenser end guard can be galvanized sheet or stainless steel sheet.

Qinjiang Company can calculate and design surface coolers based on the air volume, intake conditions,外形尺寸外形尺寸, chilled water intake temperature, cooling capacity (or exhaust conditions requirements), and other parameters provided by the customer, and take responsibility for the thermal performance specifications of the surface coolers.
