Surface Air Cooler

Features of Surface Cooler

It is a product with reasonable flake arrangement and good heat exchange effect;

It ensures the close contact between the aluminum fin hole wall and the copper tube through the strict mechanical riser tube, and is not affected by heat rise and cold shrinkage, thus stabilizing the efficient heat transfer of the surface cooler.

The unique bending process greatly reduces the volume of the surface cooler and realizes the efficient heat exchange of refrigerant, hot and cold water and air.

It is the best choice for building vacuum, purification air conditioner, variable wind air conditioner, commercial and residential air conditioner manufacturers.

The cooling water consumption is greatly reduced, and the air cooler's demand for cooling water flow and pressure supply is reduced. The delivery quality of compressed air is improved, and the water content in compressed air is reduced.

Principle of Operation Surface Cooler

Wet surface air coolers operate in a manner similar to open cooling towers, except that the heat load to be rejected is transferred from the process fluid (the fluid being cooled) to the ambient air through a heat exchange coil. The coil serves to isolate the process fluid from the outside air, keeping it clean and contaminate free in a closed loop. This creates two separate fluid circuits:

(1) An external circuit, in which spray water circulates over the coil and mixes with the outside air.

(2) An internal circuit, in which the process fluid circulates inside the coil. During operation, heat is transferred from the internal circuit, through the coil to the spray water, and then to the atmosphere as a portion of the water evaporates.

Material of Surface Cooler

Tube Material

Stainless Steel, Galvanised Steel or Metal Alloy Tubes provide varying effectiveness based on the cooling requirement of the process fluid.

Fin Material

Aluminium, Copper and other metal alloys dissipate heat based on their thermal conductivity.

Design

There are four main applied fin styles. Each has advantages in regards to heat transfer and thermal efficiency.

Cycle Requirements of Surface Cooler

In the working process of the surface cooler, the refrigerant is mainly used to absorb heat in the surface cooler, so that the temperature of the cooled space is gradually reduced. The fan coil surface cooler of the air handling unit cools the air flowing through the heat exchange fins outside the pipe through the air conditioning chilled water (refrigerant water) flowing inside. The fan sends the cooled cold air to the place of use for cooling. The refrigerant water takes the heat absorbed back to the refrigeration unit from the return pipe of the surface cooler, releases heat, cools down, and then is sent back to the surface cooler to absorb heat and cool the air flowing through And it goes on and on.

The surface cooler can effectively avoid the oxidation of heat transfer oil to a certain extent. As the heat carrier, the heat transfer oil is prone to oxidation reaction under high temperature operation, resulting in oil deterioration. Therefore, nitrogen charging protection should be carried out in the high temperature expansion tank to ensure the sealing of the system, avoid contact with air and prolong the service life of hot oil.

FAQ

Q: What is surface cooling?

A: Surface cooling is a method of reducing temperature by allowing heat to escape through the walls of a jacketed reactor, leading to a quicker cooling rate.

Q: What is the difference between an air cooler and an air conditioner?

A: An air conditioner repeatedly circulates the existing air into the room for cooling, whereas an air cooler draws fresh air from the outside and then cools it down. Furthermore, unlike an air conditioner, an air cooler does not dry out the air in the room.

Q: What are the pros and cons of air cooler?

A: An air cooler can cool a room quickly and efficiently. It is also more energy efficient than most air conditioner units and can be used in smaller spaces. However, the disadvantage of an air cooler is it has limited cooling capacity and needs a daily water change.

Q: Does an air cooler work in a closed room?

A: Yes, an air cooler can work in a closed room, but its cooling effect may be limited. If the room is closed and not adequately ventilated, the air cooler may not be able to draw in enough hot air to effectively cool the room.

Q: How does an air cooler work without water?

A: When you use an air cooler without water, it essentially becomes a fan. It will still circulate the air, but it will not cool it down or humidify it. In fact, it may even increase the temperature of the air slightly, as the fan motor generates some heat.

Q: Do all my products come in the one package?

A: If possible, we ship all units in one package. If the number of items exceeds our box sizes, multiple boxes will be used and shipped.

Q: How can I check the status and tracking of my order?

A: You will receive an order confirmation email when you place your order. Once your order ships you will receive a shipping confirmation email with your order tracking information.
