Fin heat exchanger cleaning

You will need to keep the fin heat exchanger clean every once in a while. You will find that you are able to keep it clean and take care of it with proper maintenance and cleaning, the longer it will make it last longer, which will be the better job.

Step 1 Open

The first thing you will do is open the lid of the air cooler. Due to the cooling process of the air cooler, fresh air from outside circulates throughout the office or home. Every air cooler is different, so unless you have to open it before, you may need to look at the instructions and check to see exactly how to do it. Improper doing so may cause damage to your evaporative air conditioner.

Step 2 Check

The air in your room will never be out of date. This even allows you to enjoy a free operating unit, even if the doors and windows are open. After the cooler has been turned on, it is a good idea to take the pad and double check. If they want to be in good condition without debris or molds, then they will have to be replaced. 

Make these judgments before moving on to the next step. If it does need to be replaced, then make sure you get the correct measurement, so the size you get is a usable one.

Step 3 Float valve

Take a good look at your float valve and make sure it does not stick at all. If you find it, then you will need to get cleaned up. The moisture that the air cooler injects into your indoor air uses the cooling and evaporation technology. This enhanced moisture content can prevent the sun from getting out of your skin and eyes due to the heat. Many times, you will find that hard water deposits and debris are the main reason why you have a problem. If you don’t think that something clean can solve this problem, then it’s something else, and you might want to consider replacing everything.

Step 4 Belt

Make sure you check the belt on the fan. It can be very loose because this thing may cause problems. Please make sure it is tight and only slightly push when moving. If the belt moves too much, then it will need to be replaced.

Step 5 Oiling    

It is a good idea to oil the motor parts to ensure that it can run smoothly and longer, not to mention quiet.

Step 6 Cleaning

After you have done the proper inspection, you are ready to start cleaning. At first you will be panned and scrubbed with hard water until all the stains are gone. Make sure they are all cleaned before putting it back. Look inside, there must be a lot of dust anywhere, if there is, then scrub them until they are all washed away. 

Once you are done, you will only need to simply replace the necessary parts, it is best to put them back together to complete. Now, if you are running the air conditioner, you don’t have to be surprised when you receive high electricity bills. Detector air coolers are cost-effective and efficient devices that run on air conditioners with considerably less power. 

In fact, they are not only cost-effective operations, but they can also be maintained for long hours. In addition, they are quite cheap to install and all they need is minimal maintenance. They definitely consume less electricity compared to A/C units.

Technical request for finned tube heat exchanger:

 1. Thermal performance requirements The higher the heat transfer coefficient K value of the finned heat exchanger, the better the heat transfer performance. 

To improve the heat dissipation capacity of the heat exchanger and increase the heat transfer coefficient of the finned heat exchanger, it is possible to increase the heat dissipation area of the outer wall to increase the air movement speed around the finned heat exchanger and increase the outward radiation intensity of the heat exchanger. .

 2. Economic requirements, the less metal consumption per unit heat of the finned heat exchanger to the room, the lower the cost, the better the economy. The metal thermal strength of the finned heat exchanger is a sign of weighing the economics of the heat exchanger. 

The thermal strength of metal refers to when the difference between the uniform temperature of the heat medium in the heat exchanger and the temperature of the indoor air is 1°C. 

The heat output per kilogram of mass heat exchanger per unit time. This index can be used as an index to weigh the economics of the heat exchanger of the same material. For various finned heat exchangers of different materials, the economic evaluation criteria should be weighed by the cost of heat exchanger unit heat dissipation (yuan/w).

 3. The finned heat exchanger should be equipped with equipment application and process requirements

 It has a certain mechanical strength and pressure capability; the construction method should be easy to combine into the required heat dissipation area, the construction size should be small, and the room area and space should be less occupied. The production process of the fin heat exchanger should meet the requirements of mass production.

 4. Hygiene and aesthetic requirements, the surface is lubricated, does not accumulate dust and is easy to clean, the installation of the fin heat exchanger should not affect the look and feel of the room.

 5. For service life requirements, finned heat exchangers should not be easily corroded and damaged, and have a long service life.

 Heat exchangers can be widely used in light industry, construction, machinery, textiles, printing and dyeing, electronics, food, starch, medicine, metallurgy, painting and other industries in hot air heating, air conditioning, cooling, condensation, dehumidification, drying, etc. .

 Heating heat exchanger: one of the uses including heaters and radiators.

 Finned heat exchanger structure: heat exchange tube, inlet and outlet header, frame.

 Among them, the heat exchange tube is composed of a heat exchange tube bundle, and the heat exchange tube is composed of a base tube and a fin. The quality of the heat exchange tube determines the heat exchange effect, the arrangement of the heat exchange tube affects the air resistance, and the installation method of the heat exchange tube determines the ability to withstand the temperature difference (thermal expansion and contraction).

 Commonly used heat exchange tube installation methods: fixed frame type (SRZ type, SRL type, S type), frame support type (GL type, U type). Among them, the frame is fixed, the heat exchange tube is directly welded to the frame box, the structure is simple, generally used for heat or refrigerant below 180 ℃; ) Welding, generally used for heat medium above 180℃.

 Commonly used heat exchange tube types: steel heat exchange tube (steel tube wrapped around steel fins, hot-dip galvanizing treatment), steel-aluminum composite heat transfer tube (steel tube rolled aluminum fin), copper heat transfer tube (copper tube wrapped around copper fin) , Tin lining treatment), copper-aluminum composite heat exchange tube (copper tube rolled aluminum fin), stainless steel heat exchange tube (stainless steel tube around stainless steel fin, high-frequency welding).

 Among them, the steel heat exchange tube, hot-dip galvanizing is the key, which can fill gaps, stabilize the fins, efficiently transfer heat, and efficiently prevent corrosion; copper radiator tubes, tin lining is the key. The main technical parameters of the heat exchanger: heat exchange area, ventilation net cross-sectional area, heat transfer coefficient. 

Among them, the heat exchange area affects the heat exchange, which is also the main cost parameter of the heat exchanger; the ventilation net cross-sectional area affects the ventilation resistance; the heat transfer coefficient affects the heat transfer effect. Selection parameters of drying radiator: heat medium (steam, hot water), hot air, materials. 

Among them: steam (pressure, temperature), hot water (inlet water temperature, outlet water temperature, flow rate), hot air (flow rate, inlet air temperature, humidity (water content), outlet air temperature, air resistance), materials (heat consumption, evaporation).

Water quantity) heat preservation heat exchanger selection parameters: heat medium (steam, hot water), space, region, heat preservation. Among them: steam (pressure, temperature), hot water (inlet water temperature, outlet water temperature, flow rate), space (length, width, height).
