Low maintenance condenser

Abstract

A low maintenance condenser for using in commercial refrigeration systems comprising a single metallic flat section having two or more integrally formed pipes for the flowing of a refrigerant fluid and a flat longitudinal heat dissipation section at each side of a pipe, wherein the first end of the first pipe comprising the refrigerant fluid inlet and the second end of the last pipe comprising the fluid outlet, and wherein the first end of the next pipe is connected to the second end of the previous pipe, successively until the last pipe, in order to form a single circuit having a single refrigerant fluid inlet and a single refrigerant fluid outlet.

Description

BACKGROUND OF THE INVENTION[0001]A. Field of the Invention[0002]The present invention is related to condensers for commercial refrigeration systems and more particularly to a low maintenance condenser coil for commercial refrigeration systems, which does not make use of aluminum fins.[0003]B. Description of Related Art[0004]In commercial refrigeration systems, the use of finned condenser coils and an inadequate maintenance to these devices which mainly comprise the cleaning of the coil fins, causes important problems to the refrigeration systems that ranges from a temperature rise of the system, an increase of the operative pressures, a decrease of the useful life of the components, greater energy consume to premature failures of the components, mainly of the compressor, which is an expensive and essential component of the refrigeration system.

AI Technical Summary

Benefits of technology

[0013]It is therefore a main object of the present invention to provide a low maintenance condenser for commercial refrigeration systems made of a single extruded aluminum section.

[0016]It is an additional object of the present invention to provide a low maintenance condenser of the above referred nature, which allows lengthening the maintenance intervals, or to reduce or even eliminate the necessity of maintenance depending on the operating conditions of the refrigeration system.

[0017]It is still an additional object of the present invention to provide a low maintenance condenser of the above referred nature, in which the reduced diameter of the pipes allows to reduce the amount of refrigerant gas in the system and thus to make efficient the refrigeration system by reducing the amount of power required by the compressor. The efficiency of the condenser of the present invention, also lies on the design of the heat dissipation area (the section between the pipes), which allows an optimum contact area with air for dissipating heat.

Problems solved by technology

In commercial refrigeration systems, the use of finned condenser coils and an inadequate maintenance to these devices which mainly comprise the cleaning of the coil fins, causes important problems to the refrigeration systems that ranges from a temperature rise of the system, an increase of the operative pressures, a decrease of the useful life of the components, greater energy consume to premature failures of the components, mainly of the compressor, which is an expensive and essential component of the refrigeration system.

These issues cause problems in the points of sale with the delivery of the final products that are not cooled enough by the refrigeration systems and therefore a rise of the operational costs.

Said condensers have good performance, however they use a larger quantity of refrigerant gas since the circuits are longer, thus increasing the power consumed by the compressor and the energy consume.

Also, since said condenser coils are bigger, they require a larger space for its installation and therefore, there are not suitable for smaller refrigeration systems where the installation of such condenser coils is impossible.

Finally there are technologic and economic limitations when using said condensers in combination with coils having small diameters.

There are more efficient than the condenser coils without fins, however they are less durable specially when exposed to saline environments due to the material that are made of (steel).

There are also low maintenance condenser coils made of cooper which integrates as secondary heat dissipation area an extruded aluminum section, wherein the efficiency of the coil is determined by the contact area between both materials, furthermore, this kind of condenser is very expensive since it uses additional material for heat dissipation.
