COUNTER FLOW EFFECT

Counter flow

Counter flow and parallel flow refer to the direction of fluid movement in a heat exchanger, such as coils. In counter flow, the hot and cold fluids move in opposite directions, maximizing the temperature difference along the entire length of the exchanger. This results in efficient heat transfer. In contrast, parallel flow involves both fluids moving in the same direction. While it still allows heat transfer, the temperature difference decreases along the length of the exchanger, potentially leading to lower efficiency...

Fin Tube Coils Manufacturing Process

Fin Tube Coils Manufacturing Process

1. Material Selection: - Choose the base material for tubes and fins based on factors such as thermal conductivity, corrosion resistance, and compatibility with the working fluid and environmental conditions. There are distinct choices for each part such as Copper or Stainless Steel for tubes, and for fins we can choose between Copper and Aluminum. 2. Tube and Fin Design: - Optimize the design of tubes and fins to meet the specific heat transfer requirements of the application. Consider parameters like tube diameter,...

Water Coils

Water coils play a critical role in HVAC systems, including Air Handling Units (AHUs), Fan Coils, and Ducted Splits, contributing to efficient heating and cooling. Radiran, being a prominent manufacturer in Iran, is known for providing high-quality water coils. Here's how these coils are used: Air Handling Units (AHUs): - Heating Coils: In AHUs, heating water coils warm the air as it passes over them. Hot water which is provided by the boiler, passes through tubes in the coil and...

The role of coils in the refrigeration cycle

The role of coils in the refrigeration cycle

Coils are known as the most important component in air conditioning and refrigeration systems. One of the most important heating and cooling cycles is the refrigeration cycle. Condenser coils, usually located in the outdoor unit of the system, help to dissipate the heat that has been absorbed from the indoor space. These coils operate at high pressure and temperatures and help to convert the refrigerant from gas to liquid. On the other hand, the evaporator coils, which are located inside...
