摘要:
On-Line and Off-Line methods of simultaneously cleaning and disinfecting an industrial water system are described and claimed. The methods involve the addition to the water of the industrial water system of a Compound selected from the group consisting of the alkali salts of chlorite and chlorate and mixtures thereof; and an acid, followed by allowing the water in the industrial water system to circulate for several hours. The reaction of the alkali salts of chlorite and chlorate and acid produces chlorine dioxide in-situ in the water of the industrial water system. The chlorine dioxide kills microorganisms and the acid acts to remove deposits upon the water-contact surfaces of the equipment. An alternative method involves the use of a chelating agent and a biocide. Other possible cleaning and disinfection reagents may be added as needed including corrosion inhibitors, chelating agents, biocides, surfactants and reducing agents. These cleaning and disinfecting methods work in a variety of industrial water systems including cooling water and boiler water systems.

Fin material for a heat exchanger, which comprises: a fin material; a water-based resin paint coated on said fin material surface; a hydrophilic coated on said paint coating; and, antibacterial and antifungal powders fixed by said hydrophilic coating and paint coating, wherein the half or less portion of respective powders are exposed to the outside of the hydrophilic coated film so that the properties of said powders can be retained for a sustained period of time and heat exchanger for air conditioner provided therewith.
摘要:
A heat exchanger made of aluminum and apt to collect water thereon, e.g., an evaporator of an automotive air conditioning system is provided with an anodized surface layer which has numerous pores therein. Fungicide is filled in the pores to eliminate an offensive smell ascribable to mold.

Disclosed herein is a hydrophilic coating that includes an adhesive agent; an insolubilizer for insolubilizing the adhesive agent; titanium dioxide; and a metal oxide selected from the group consisting of silver oxide, copper oxide, iron oxide, magnesium oxide, and combinations thereof. The hydrophilic coating is useful on the heat transfer surfaces of a condensing heat exchanger.
摘要:
A method for dispensing a milk-containing composition consisting of a flavour composition and a milk product by supplying the milk product to a removable heat exchanger provided with a flexible tube, wherein the flavour composition is added to the heated milk product in random order after the heat exchanger, cooling the milk product that remains in the heat exchanger after the latter has been emptied for the larger part by means of the heat exchanger after a specified period of time, calculated from the last time dispensing of the milk-containing composition took place, so that it will keep for a comparatively prolonged period of time, and subsequently heating the milk product for a next dispensing action and replenishing it with a next amount of milk product shortly before mixing it with the flavour composition, whereupon the hot milk-containing composition is discharged. The invention further relates to a heat exchanger obviously intended for use in this method.
摘要:
The invention relates to a system that is functionally associated with a refrigeration unit (1), said system comprising a primary tank (6) for the inflow of the water to be treated, and an inner tank (7) for cooling and mixing the water. Said tank (7) contains an exchanger (13) through which the liquid gas from the refrigeration unit (1) is passed, at the same time as the water entering the primary tank (6) accesses the cooling and mixing tank (7) from the primary tank, said cooling and mixing tank comprising water suction tubes (23) that converge in a three-way valve (25) connected to a water recirculation pump (15) via which the water is driven inside the exchanger (13). The treated water leaves via an outflow line (27).
摘要:
A fin for a heat exchanger of an air conditioning apparatus includes a base material, a hydrophilic layer, and a corrosion-resistant layer provided between the base material and the hydrophilic layer. A contact angle of a surface of the hydrophilic layer with water is no more than 50 degrees. A water content of the hydrophilic layer per dm2 of the surface of the hydrophilic layer being at least 60 mg/dm2 and no more than 300 mg/dm2.
摘要:
Disclosed is a heat exchanger wherein an antibacterial member can be installed at a low cost and without using a dedicated fixing member, a drop in heat exchange efficiency due to the installation of the antibacterial member is prevented, and which can maintain high design flexibility. The disclosed heat exchanger is provided with a heat radiating member comprising at least a plurality of tubes which are arranged in a planar manner and through which a heat exchange medium flows, and the heat exchanger is characterized by being constructed such that a water absorption sheet substrate for holding antibacterial components is partially attached to the heat radiating member, and the antibacterial components can disperse, following the surface of the radiating member, via water components which have been absorbed by the water absorption sheet substrate.
摘要:
According to the invention, in order to prevent a film from forming which obstructs the transfer of heat in heat exchanger pipes, the heat exchanger pipe comprises an external side which is adjacent to the external surface and which is impinged upon by a steam medium, and an inner side which is adjacent to an inner surface and which is impinged upon by a coolant, such that the outer surface is provided with a first layer which reduces the adhesion of the steam on the outer surface and/or the inner surface is provided with a second layer which reduces the adhesion of a coolant to the inner surface and which is embodied as a biocidal layer. The invention relates to a heat exchanger and to the use thereof.
摘要:
An improved method and apparatus to prevent clogging of condensate drain lines with a biocide delivery system that prevents the growth of bioorganic growth in the liquid trap using time release biocide tablets or liquid biocide. When using solid biocide tablets erosion and dissolution of the tables is reduced. When using liquid biocides, combination of initial release followed by gradual release of residual liquid biocide in the drain water is attainable. Drain line are promoted from clogging while being installed anywhere on the drain line upstream of the liquid trap. The apparatus can also be incorporated with a liquid trap, allowing placement anywhere in the drain line.
