Refrigeration apparatuses are arranged basically in two ways: the monoblock and the SPLIT refrigeration configurations. That is a result of the way in which the different refrigeration components are associated and interconnected. There are four major components in refrigeration units: the condenser, the refrigerant control assemblies, the compressor, and the evaporator (
In the monoblock refrigeration configuration arrangement, all of the refrigeration components are gathered within a rigid chassis platform (
Those units are one piece, meaning that their condenser, refrigerant control assemblies, compressor, and the evaporator are fixed to one rigid chassis and enclosure. No refrigeration components are outside the enclosure. All of the refrigeration components are interconnected by the use of rigid refrigerant lines (tubes). The heat rejecting sector and the heat absorbing sector are rigidly joined together in the same platform and enclosure, even though each sector has its own sub-housing (
These monoblock refrigeration machines may have several condensers, refrigerant control assemblies, compressors and evaporators, but the machines are still configured as one self-contained apparatus. Usually, these units are factory ready. They arrive to the end users charged and ready to go. There is no need to perform any assembling or service to the refrigeration unit itself at the time of installation. For example, that is the case with window residential air conditioning units, vending machines, large truck-trailer refrigeration units, maritime container refrigeration units and others. They have to be placed at the desired and correct location as one rigid piece of equipment (
When those monoblock refrigeration equipment have various heat absorbing sectors, they are called multi-zone monoblock refrigeration units, because they still conform with one rigid platform and enclosure system (
In the SPLIT refrigeration configuration arrangement, the refrigeration components are gathered within two or more rigid chassis platforms (
The refrigeration components are arranged and assembled in various platforms and enclosures, dividing them into various separate rigid chassis and enclosures: the chassis and enclosure that contains the heat rejecting sector, and the chassis and enclosure that holds the heat absorbing sector. Usually, this type of refrigeration arrangement congregrates the condenser, the refrigerant control assemblies and the compressor as the components of the heat rejecting sector, leaving the evaporator assembly as the sole component of the heat absorbing sector.
The various separate rigid chassis platform and enclosure assembling are interconnected by either rigid or flexible refrigerant lines, tubes or hoses (
Those elements, the separate platform enclosures and the non-integrated refrigerant lines give that type of refrigeration units the ability to be fixed or installed in a variety of different shape, surfaces or locations. This characteristic gives flexibility to the separate enclosures arrangement, not really to the separate platforms themselves. The various rigid platforms and enclosures could not be deformed into taking different shapes. Rather, the two or more interconnected pieces of equipment can be installed in a variety of different positions and applications, as various separate remote enclosures.
That split type of apparatus is not self contained. There is a need to perform a final assembling on site. At the least, the refrigerant lines must be installed at the premises (
The split refrigeration units could have several condensers, refrigerant control assemblies, compressors and evaporators. That type of SPLIT configuration unit is called MULTI-SPLIT unit (
Examples of the split and multi-split refrigeration machines are: the air conditioning unit of an apartment with one, two or more rooms to be independently temperature controlled by only one remote refrigeration unit. The air conditioning apparatus of a city bus, where the heat rejecting sector (the condenser, the refrigerant control assemblies and the compressor platform and enclosure) is placed outside, underneath or in back of the bus. The heat absorbing sector, the evaporator platform and enclosure, is placed inside of the vehicle at the ceiling. In the refrigeration equipment of a perishable food delivery van, the heat rejecting sector is roof-top mounted outside the vehicle, and the heat absorbing sector is wall-mounted inside the cargo box.
Needs exist for improved refrigeration systems.
The new flexible refrigeration platform gives life to a totally new flexible-monoblock refrigeration unit configuration concept. The new system comes complete and ready to plug in and use. One unit may be configured in several ways. Requirements are eliminated for an inventory having several different configurations.
In the new flexible-monoblock refrigeration configuration arrangement, all of the refrigeration components are gathered within its one and only flexible chassis platform. These units are one piece, meaning that their condenser, refrigerant control assemblies, compressor, and the evaporator are fixed to their one and only integrated flexible chassis. No refrigeration components are outside its enclosure. There is no need to perform any assembling or service to the refrigeration itself at the time of installation.
This invention provides a totally new concept of a flexible-monoblock refrigeration configuration arrangement. Instead of fixing the refrigeration components into one rigid integrated platform, or into various rigid separate platforms, the present invention fixes them into one “flexible” integrated platform (
The new invention takes the traditional four different groups of refrigeration components, and assigns them individual sub-platforms (
The condenser, the refrigerant control assemblies, the compressor and the evaporator (all of them individually) are conforming independent groups that are fixed or attached into sub-platforms of the new flexible refrigeration platform by means of the implementation of a new flexible chassis that at the same time, houses the new flexible refrigerant lines that interconnects all of the refrigeration components.
In the new flexible-monoblock refrigeration units (
The new flexible monoblock refrigeration system can be configured in many different forms using parallel rigidly interconnected side plates. The sub platforms for mounting major elements are shown in
Reconfiguration is shown in
The different reconfigurations shown in the second line of
Condenser fans f are also connected to the rigid frames above the condensers, as shown in the bottom line in
The Flexible Monoblock has one chassis that is reconfigured in many shapes. The subassembly platforms are not limited to currently available best technology in compressors, condensers and evaporators. As new technological advances are made, new compressors, condensers and evaporators may be mounted on the subassembly sub platforms as indicated in
The sub platforms are connected to rigid parallel mounting side plates. In some embodiments the elements are connected directly to the side plate. Nothing loads or stresses the parts. The drivers are mounted directly on the compressor sub platform.
The side plates and rigid interconnections are connected by frames directly to the trailer truck box or bus body with simple connections so that the entire refrigeration units may be removed and replaced.
Exterior and interior covers are attached to the trailer, truck or bus. The covers stay with the truck. Only the refrigeration units are removed and replaced.
The refrigeration units are available in four different width sizes in two different heights.
The side elevations show the ends of refrigerant lines, which are long U-shaped tubes. The long legs of the tubes twist as the monoblock chassis is reconfigured.
The subassemblies s.a. may be separated along lines A, B, C and D in
The disclosure of copending U.S. patent application Ser. No. 12/214,403 filed Jun. 18, 2008, now U.S. Pat. No. 7,614,242, is incorporated by reference herein as if fully reproduced herein.
These and further and other objects and features of the invention are apparent in the disclosure, which includes the above and ongoing written specification, with the drawings.
The flexible monoblock system 90 is the same in both trucks. Only the flexible configuration has been rearranged.
The flexible monoblock system 90 mounted on a passenger vehicle 120 has a curved horizontal rooftop configuration 121 in which sub platforms 61,63,65,67 are mounted. Fan f blows air through condenser platform 71, and blower b circulates cooled air in the interior of the passenger vehicle 120.
Compressor 1 and a compressor driver motor 121 are mounted on the compressor platform 61. The temperature control sub assembly 3 is mounted on the control platform 63. The condenser sub-assembly 5 is mounted on the condenser platform 65. The evaporator temperature control sub-assembly 123 may be mounted on platform 65 or on a separate platform 124. The evaporator coil sub-assembly 7 is mounted on the evaporator platform 67. Insulating wall 127 is mounted between the side fixing plates 119 to separate the chilled evaporator 7 from the outside heat rejection components.
In one embodiment, such as shown in
When the sub platforms 61,63,65,67 are moved to different positions, the fixed refrigerant line connectors 140 prevent the component connectors from moving or being stressed.
The fixed connectors clamp ends of the refrigerant lines to the platform. The line connectors along the edges of the platforms have two aligned openings. One opening clamps an end of a line. The other opening is a guide opening that allows a portion of another line to pass through the connector while keeping the portion of the other line alignment with the width of the platform.
In one embodiment, as shown in
While the invention has been described with reference to specific embodiments, modifications and variations of the invention may be constructed without departing from the scope of the invention.
This application claims the benefit of U.S. Provisional Application 60/961,571 filed Jul. 20, 2007, which is hereby incorporated by reference in its entirety.
