The different characteristics of the refrigeration effect of the horizontal condenser and the vertical condenser

There are many types of condensers, and the most commonly used ones are vertical condensers and horizontal condensers. Today, we will make a simple comparison of these two types of equipment; the horizontal condenser and the vertical condenser are in addition to the placement and In addition to the different distribution of water, the temperature rise of water and the amount of water used are also different. The cooling water of the vertical condenser flows down the inner wall of the pipe along the gravity, and it can only be a single stroke. Therefore, to obtain a sufficiently large heat transfer coefficient K, a large amount of water must be used. The horizontal condenser uses a pump to pressurize the cooling water into the cooling pipe, so it can be made into a multi-stroke condenser, and the cooling water can get a sufficiently large flow rate and temperature rise (Δt=4～6℃). Therefore, the horizontal condenser can get a large enough K value with a small amount of cooling water. However, if the flow rate is excessively increased, the heat transfer coefficient K value does not increase much, while the power consumption of the cooling water pump increases significantly. Therefore, the cooling water flow rate of the ammonia horizontal condenser is generally about 1m/s. Freon horizontal condensation The cooling water flow rate of the device is mostly 1.5-2m/s.
