Surface air cooler dirt soaking agent

Abstract

The invention discloses a surface air cooler dirt soaking agent which comprises the following raw materials in parts by weight: 11-16 parts of sodium dodecyl benzene sulfonate, 14-22 parts of disodium edetate, 5-9 parts of quaternary ammonium salt cationic surfactant, 4-6 parts of aluminum mildew preventive, 5-11 parts of Bordeaux mixture, 0.5-2.5 parts of corrosion inhibitor, 1-4 parts of cosolvent, 2-5 parts of chelator and 77-84 parts of water. The preparation method comprises the following steps: mixing the sodium dodecyl benzene sulfonate, disodium edetate and quaternary ammonium salt cationic surfactant, heating to 60 DEG C, adding the cosolvent and water, stirring for 40 minutes, cooling to 40 DEG C, adding the aluminum mildew preventive, Bordeaux mixture, corrosion inhibitor and chelator, stirring for 30-50 minutes, and cooling to room temperature. The surface air cooler dirt soaking agent adopts the soaking mode to remove dirt on the surface air cooler, does not need disassembly, reduces the cleaning work load and the influence of the disassembly and assembly work, has favorable effect dirt removal effect, does not corrode the components of the surface air cooler, prolongs the service life of the surface air cooler, and ensures the high-efficiency heat transfer of the surface air cooler.

Description

technical field [0001] The invention relates to a soaking agent, in particular to a dirt soaking agent for a surface cooler. Background technique [0002] There are two types of surface coolers: one is the heat exchanger of the fan coil unit, its performance determines the ability of the fan coil unit to deliver cold (heat) and its influence on the air volume. This device is generally found in air conditioners. The second is the air-cooled finned condenser in the air conditioning unit. [0003] The surface cooler dissipates heat for the refrigerant and discharges the heat to the outside. It condenses the high-temperature and high-pressure gas compressed by the compressor into a low-temperature and high-pressure liquid. The fan coil surface cooler of the air handling unit cools the air flowing through the heat exchange fins outside the tube through the air-conditioning chilled water (refrigerant water) flowing inside, and the fan sends the cooled air to the place of use for...

Problems solved by technology

However, since fan coil units are generally equipped with primary-effect filters with relatively large holes, dust inevitably passes through the filters and adheres to the pipe or fin surface of the fan coil unit at the beginning of operation.

If it is not cleaned in time, the amount of heat exchange between the cold hot water in the coil and the air flowing out of the coil will be reduced, and the heat exchange efficiency of the coil cannot be fully exerted.

If there is a lot of dust attached, and even some air passages between the ribs are blocked, the air supply volume of the fan coil unit will be reduced at the same time, further reducing its air conditioning performance.
