摘要:
Heat exchanger processes are disclosed. A heat exchanger process uses a heat exchanger. The heat exchanger has a surface positioned to be contacted by a fluid. The heat exchanger process includes contacting the surface with the fluid by transporting the fluid through the heat exchanger and transferring heat between the surface and the fluid. The transporting is at a rate of less than 2 meters per second, the surface includes a fouling-resistant coating, the fluid includes particles known to cause fouling, or a combination thereof.

An assembly comprises a wet compartment (100) having at least one inlet opening for allowing water to enter the wet compartment (100), a functional unit (2) located in the wet compartment (100), a dry area (200) which cannot be reached by water and which is outside of the wet compartment (100), a barrier (110) situated between the dry area (200) and the wet compartment (100), and at least one energy source (20) which is arranged and configured to emit energy for preventing biofouling of at least an exterior surface (17) of the functional unit (2), wherein the energy source (20) is arranged in the dry area (200), a path (112) being present between the dry area (200) and the wet compartment (100) for allowing energy emitted by the energy source (20) during operation thereof to reach the wet compartment (100), through the barrier (110).
摘要:
A low temperature Freon, where indoor air in an air handling unit goes through an indoor coil. Do to the fact that indoor coil fins' surface temperature is below freezing, ice will build up on surfaces of the fins, icy/wet surfaces will catch foreign substances from the air. Air in the center of indoor coil is passing through without cooling the indoor air.Mixture of the cooled and the by passed air are resulting pleasant and clean indoor air. Temperature sensors installed on surfaces of indoor coils opens and closes according to set temperature, turning blower motor on and off.

The present invention relates to a method and a system for controlling the circulation of water films on the exchange walls of an exchange surface of a cooling tower. It comprises combining a tank and a dispenser lip to ensure that the film has a specific thickness and that it adheres to the exchange wall right from the moment it starts to flow and repeatedly so, on each exchange wall. The exchange walls between air and water are horizontally sloping at a small angle, thereby ensuring that the water flows by force of gravity and, at the same time, limiting the speed increase on the plate to avoid the droplets from being pulled away by the airflow. The water films are recovered in recovery troughs perpendicular to the flow of the water films on the plates. These troughs are tilted horizontally, and enable the recovery of the water films without being crossed by the air flows. The air is blown in by nozzles which are interposed between the water flow plates in such a way that the airflow is in a counter-current flow or, if necessary, in a cross-current flow, relative to the water films thus enabling the evaporation of the water that cools the water flow on the exchange plates without forming liquid aerosols.

A ceramic coated heat exchanger component and method for making the ceramic coated heat exchanger component by creating porous metal oxide coatings on an aluminum surface of the heat exchanger component by plasma electrochemical deposition of a metal oxide on the aluminum surface and layering an odor neutralization agent on the porous metal oxide ceramic coatings to form an odor remediation ceramic coating on the heat exchanger.
摘要:
A surface polyaniline layer comprising a polyaniline and/or a derivative thereof capable of generating active oxygen or hydrogen peroxide upon the reaction with the water component in external air that comes in contact therewith, is formed on at least a portion of the outermost surface of a base body constituting tubes and/or fins, wherein a benzenoid/quinoid ratio in the surface polyaniline layer (defined as a ratio of an absorbancy of the benzenoid structure to an absorbancy of the quinoid structure in the polyaniline and/or the derivative thereof) is in a range of about 0.5 to about 3.0.
摘要:
The present invention relates to a hydrophilic antimicrobial coating composition for an air conditioner evaporator of a vehicle with improved durability. In one embodiment of the present invention, the antimicrobial composition comprises a hydrophilic organic polymer with molecular weight in the range of about 4,000 to 8,000, a smoothing agent, an antimicrobial agent, and deionized water. In particular, the degree of polymerization between the hydrophilic functional group and a crosslinking group of the hydrophilic organic polymer is greatly improved. The antimicrobial composition is prepared with particles with a diameter of a few nanometers, which increases the number of particles per unit area and reduces the decomposition rate of the coated layer.

The invention concerns inserts in the moist/wet region of cooling towers, which essentially consist of plastic. An additive that prevents or considerably reduces soiling through the formation and buildup on the inserts during subsequent use is added to the plastic.
摘要:
A method of controlling Legionella bacteria in cooling water systems is described. The method involves the heating of recirculating cooling water to temperatures of 70° C. for sufficient time to kill the bacteria. The method functions best in combination with chemical bactericides.
摘要:
This air conditioning apparatus having sterilization function which can maintain the sterilization function for a long time period. The air conditioning apparatus having a sterilization function comprises a sterilizing coating layer formed on the surface of a component, wherein the sterilizing coating layer has copper or copper alloy particles dispersed in a resin matrix. The coating layer is formed by dispersing fine copper or copper alloy particles having a maximum particle size of about 2.5 μm or less into an epoxy or epoxy-acryl synthetic resin, and covered on the surface of a component of the air conditioning apparatus such as a heat exchanger. The maximum content of the copper or copper alloy particles in the coating layer is preferably about 18 to 31 wt %. The thickness of the coating layer is preferably less than the maximum size of the particle.
